Description

  The present invention relates to a modification treatment agent, a method for modifying a heat history silicate, and a binding shape body having a heat history silicate modified. More specifically, a “reforming agent” exceeding pH 12 for reforming wastes composed of heat history silicate composed of dormant components, waste that coexists with heat history silicates, particularly harmful substances, through an aqueous solvent. "Reforming treatment method" that applies detoxification treatment and shaping treatment to a series of work processes that allow substances to be used and treated at least at room temperature, and reforms to waste that coexists with harmful substances Providing a “bounded shape body” that has been subjected to detoxification treatment and shaping treatment as a water-resistant, non-polluting recyclable material that has a pH of less than 10 and is not re-mudged in water. There is technology to do.

  Furthermore, in the present invention, a heat history silicate composed of a dormant component is used as a material to be modified, and an activity prepared via water by combining a modifying agent exceeding pH 12 and a function-imparting agent as necessary. A series of shaped admixtures, or shaped processed products that have been processed into shapes, or processed processed adhering materials on the surface of the substrate to be applied, are released into an atmosphere at least at room temperature to form a bound shape. In-situ non-molded product, water-resistant granular product or shape-processed molded product that is a recycled material that has been modified by the work process, or a binder molding active product that is integrated with the target substrate Bonded materials provided for various uses as laminated materials, granule aggregates or injection-filled integrated products as industrial materials, construction / civil engineering materials, life-related materials, plant growth materials, environmentally friendly materials or preference materials Body on.

  The general background art related to the present invention is a solidified body and a hardened body prepared by utilizing an inorganic solidifying material that exhibits hydraulic properties at room temperature, a curing agent, a binder, a binder, and the like. In related technical fields such as binders. In addition, the characteristic background art relating to the present invention is coexisting in heat history silicate composed of a dormant component composed of a silicate compound, in particular, technology for recycling and recycling wastes as bound shapes and wastes. It is in the insolubilization treatment technology for harmful substances, especially coexisting heavy metals. These background technologies lie in the technology that enables low-load and energy-saving in the environment demanded by society, and can safely improve and maintain the environment at low cost.

  In particular, the construction and recycling of wastes has been proposed for the treatment and disposal of wastes, and under conditions where the environment is adequately protected without adversely affecting human health and animals and plants, centering on recycling. The main premise is that it will be treated and disposed of. Therefore, hazardous substances contained in wastes are not allowed to diffuse and contaminate the living environment, and treatment, disposal and treatment methods that cannot respect the environmental standards stipulated by the law are strictly prohibited. There is also a need for a low-cost recycling technology for waste that enables a low-load environment.

  Therefore, as shown in the background art, we faced the reality that dioxins coexisting in wastes or harmful chemical substances such as harmful elements are adversely affecting the living environment and human health. It is possible to protect and improve the living environment of mankind by addressing the “standards that are desirable to protect and protect the human health and protect the living environment” indicated in the “Basic Law” and related instructions, notifications, ordinances, etc. It is important to develop processing technology.

  Currently, landfills that are generally designated as specially managed areas are used for the disposal and disposal of waste, sludge, husks (incineration ash), etc., which are mainly silicate compounds among general and industrial waste. It has been disposed of by dumping and landfilling. At present, however, it is difficult to secure a dumping site or landfill site for dumping / landfilling wastes, especially wastes that are coexisting with harmful elements and dioxins and are released and diffused. The situation where waste is accepted in the living environment is very difficult. Therefore, in the future, there will be no way for society to allow means and methods for treating and disposing of wastes that elute harmful elements and release dioxins by dumping or landfill.

Hazardous elements From the above situation, of course, wastes, especially wastes that are mainly composed of silicate compounds, generally contain harmful elements and are eluted. Guidelines for soil contamination surveys and countermeasures related to heavy metals, etc., and provisional guidelines for soil and groundwater contamination surveys and countermeasures related to organochlorine compounds, etc. (1994 Guidelines) have been completely revised. The “Survey / Countermeasure Guidelines” and the operational standards were formulated and notified to prefectures and related ministries and agencies. Hazardous element groups covered by environmental standards under these laws include cadmium, arsenic, mercury, lead, chromium, selenium, boron, and fluorine.

Dioxins Also, new environmental standards for dioxins including PCBs were set in 1999. The soil standard was set to 1000 pg / g, and 250 pg / g was used as a survey index. Measures such as immediate removal are regulated. In addition, when disposing of dust collected from incinerator dust collectors and incineration ash and other husks subject to regulation under the Special Measures Law for Countermeasures against Dioxins, the amount of dioxins contained is It is said that it is necessary to treat the incinerated ash and other burning hu to be within 3 ng-TEQ per 1 g. On the other hand, the environmental standard for water quality is 1 pg / liter. In addition, in garbage incineration facilities, sewerage end treatment facilities, paper pulp manufacturing industry, vinyl chloride manufacturing facilities, etc., the rate is 10 pg / liter. The atmosphere is enhanced to 0.6 pg / m ³ .

  However, the disposal of waste, etc., is regulated by the “Act on Waste Disposal and Cleaning” (Waste Removal Law). Currently, the disposal and disposal methods for waste, etc. are dumped and landfilled in specific management areas. However, as a well-developed treatment / disposal method, wastes are converted into (1) molten slag and supplied to tiles, blocks, bricks, coarse aggregate, sand, etc., (2) cement Supplying to tiles, blocks, bricks, lightweight aggregates, etc. by molding solidification technology using a solidifying agent such as (3) A method of supplying to cement production secondary materials, soil improvement materials, etc. has been adopted and partially recycled .

  However, the molten slag method requires a high temperature to melt the incinerated ash once incinerated. As a result, it consumes a large amount of important thermal energy resources and releases a large amount of carbon dioxide, leaving challenges for securing thermal energy resources and combating global warming. Moreover, since the molten slag method requires heat treatment at high temperatures, it requires expensive melting equipment and exhaust gas treatment equipment, and the molten slag method can be used for incineration ash treatment with low cost and low load. Therefore, it is difficult to supply incinerated ash as an inexpensive processed product.

  In addition, in the molding and solidification method using a solidifying agent such as cement, the cement contains hexavalent chromium which is essentially harmful, and in addition to the harmful elements eluted from secondary products, harmful hexavalent The fact that chrome is diffused and contaminated in the living environment is inevitable. In addition, the supply of raw materials for manufacturing admixtures to cement admixtures and other factors has a negative impact on the future demand for cement resulting from the slowdown of public works in recent years. There are many expectations for the future of cement processing and using a large amount of waste.

  In general, dioxins are decomposed and detoxified by exposure to a temperature of 450 to 500 ° C. or higher, so that they are decomposed at a temperature higher than this. There is a tendency to synthesize dioxin again in a cooling atmosphere, and if dioxin is simply burned, it is not in a detoxified state. Therefore, detoxification is performed using various catalysts such as titania and vanadium in combination, but a special expensive apparatus is required, and it is not an inexpensive treatment method. Although a technique for decomposing dioxins at a low temperature has been disclosed, many are differentiated over a period of months using specially selected microorganisms or enzymes, which is not economical.

  From the above situation, a project to secure a reliable processing and supply destination for next-generation wastes is an important issue. In particular, it is judged to be important to establish technology for treating and disposing of wastes by methods and means that do not diffuse and contaminate harmful elements and dioxins that are eluted from wastes into the living environment. Under these circumstances, a number of technologies relating to treatment and disposal have already been disclosed in the past, and many researches and invention technologies have been disclosed.

  In the conventional technology, the processing technology that fixes and insolubilizes 8 types of harmful elements (cadmium, arsenic, mercury, lead, chromium, selenium, boron, fluorine) that are eluted from wastes individually as the processing target Many have been disclosed. In particular, as a detoxification treatment technology for water-soluble heavy metals that adversely affect the living environment, the soil ground and wastes contaminated with water-soluble heavy metals are treated, and drugs and treatment agents are applied from outside the system. Many techniques for adding and blending to insolubilize water-soluble heavy metals have been developed and disclosed. However, in these techniques, there is no disclosure of a technique for efficiently insolubilizing harmful heavy metals that are water-soluble and harmful boron and fluorine acids by utilizing the components of the material to be treated.

  In addition, since the above eight types of harmful elements basically have different properties, there is no disclosure of a processing technique that fixes and insolubilizes all eight different types of harmful elements in a single simple processing material at least at room temperature. Thus, there is a need for a processing technique for stably fixing and insolubilizing eight different types of harmful elements, particularly boron and fluorine acids, at the same time by using a single simple processing material without distinguishing heavy metals.

  Typical treatment technologies for fixing and insolubilizing heavy metals: 1) Technology that involves wastewater treatment but cleans heavy metals with water, etc. 2) It involves exhaust treatment, but fumes are recovered by pyrolysis of heavy metals. 3) a technique for chelating heavy metals with a chemical compound such as a chelate, and 4) a technique for coating heavy metals with cement or the like. In particular, there are many disclosures of techniques for fixing and insolubilizing heavy metals with chemicals and treatment materials due to treatment costs.

  Recently, many treatment techniques for insolubilizing boron or fluorine in water have been disclosed. For example, in Japanese Patent Application Laid-Open No. 2004-283787, a calcium-based material such as cement or slaked lime is used for soil containing contaminants. Treatment with metal ion-based materials such as ferrous salts, ferric salts, aluminum salts; metal iron, metal aluminum, metal zinc, etc. Treatment with metal materials; Chelate materials such as dialkyldithiocarbamic acid; Treatment with inorganic adsorbents such as apatite and zeolite; Treatment with ion exchange resins; Treatment with chelating resins having functional groups such as iminodiacetic acid Technology is disclosed.

  In JP-A-2004-089816, Portland cement, mixed cement, eco-cement, special cement, which is selected as a hydraulic binder for soil from which fluorine or boron elutes or fluorine or incinerated ash from which boron elutes, A technique for insolubilizing eluted fluorine or boron by adding and mixing a hydraulic binder containing magnesium oxide, magnesia cement, lime or the like or further containing calcium salt is disclosed. However, there is no technical disclosure that activates the object to be treated with cement.

  Furthermore, as a harmful element group that elutes from wastes, a representative technology of treatment technology that immobilizes heavy metal groups such as cadmium, arsenic, mercury, lead, chromium, selenium, etc., without specifying fluorine or boron, and insolubilizes them. Disclosure is, for example, an alkali carbonate and ferrous sulfate disclosed in JP-A-09-155319, a technique for insolubilizing heavy metals that are eluted by kneading and solidifying by adding cement to sewage sludge incineration ash, Also, published patents such as JP2003-175370, JP2002-001273, JP2000-279971, etc. describe heavy metals that elute by adding iron salt such as ferrous sulfate to sewage sludge incineration ash and kneading and solidifying it. A technique for insolubilizing a kind is disclosed.

  Further, in the prior application (Japanese Patent Laid-Open No. 12-263661) by the present inventors, a wet fluid obtained by dispersing a silica-alkali composition having a silanol group and an aluminate composition of an alkaline earth metal in water is used.

Furthermore, in the prior application technique by the present inventors (Japanese Patent Laid-Open No. 2002-128550), 20 parts by mass or more of an alkali-type curing agent composed of a calcium composition and an alkali composition is added to 100 parts by mass of a silicate material. A technique is disclosed in which a deformable admixture is prepared together with an aqueous composition to provide a water / heat resistant solidified product.

  Furthermore, the prior application technique (Japanese Patent Application Laid-Open No. 2002-249348) is composed of a composition mainly composed of four silanol group-containing compounds: a sulfur oxyacid salt composition, an alkali composition, a calcium composition, and an aqueous composition. A room temperature hydraulic solidified material is disclosed. In addition, the prior application technique (Japanese Patent Laid-Open No. 2003-013061) discloses a detoxifying treatment agent for a powdery one-pack product composed of a calcium composition, an aluminum sulfate composition, and an aluminum phosphate composition. . In addition, in the prior application technique (Japanese Patent Application Laid-Open No. 2003-122953), a calci-silica composition that has been heat-treated at a temperature of 800 ° C. or lower in advance by adding calcia and the like to volcanic ash containing sulfur oxide in response to a thermal history is prepared. Hydraulic solidifying material comprising activated silicate having silanol group as a constituent component by adding sodium hydroxide to calcium-silica composition which has not been sufficiently inactivated to ensure quality retention The manufacturing method is disclosed.

  In addition, in the prior application technique (Japanese Patent Application Laid-Open No. 2004-050158), a powdery one composed of active silica having a silanol group, reactive alumina, sodium hydroxide and a calcium composition as an immobilizing material for heavy metals. Although the composite component of the pack is disclosed, no special means or device in consideration of the product quality retention is disclosed. In addition, in the prior application technique (Japanese Patent Application Laid-Open No. 2005-097069), an active silica having sodium and silanol groups is added to the inert silicate prepared as a mixed raw material at 820 ° C. or higher, and sulfament is provided if necessary. Consists of 3 basic components added and 4 composite components with supplemental components added to the basic components. Shaped (solidified, bound, poured, etc.) and harmless by reaction via aqueous solvent Disclosed is a modified processing agent technology consisting of a silanol group-containing cured material that has a shelf-life ensured with a granular composition that exhibits a processing function (below pH 10, immobilization / decomposition, etc.) at a temperature of 190 ° C. or less at room temperature Has been.

  However, in these conventional techniques, at least by a modification treatment operation at normal temperature, a modification treatment agent exhibiting strong alkalinity of 12 or more at a pH value constituted by three components of a calcium-containing component, a sodium-containing component and a sulfur-containing component, Activated and utilized the dormant component silicate compound that constitutes the waste consisting of silicates that have undergone a thermal history, the alkaline component and harmful element group coexisting as harmful substances in the system at a pH of less than 10 The technology to fix as water-insoluble minerals, and the water-insoluble minerals that have fixed and formed harmful substances are not only water-based solvents in the neutral range but also pH 4 in the acidic range where acid rain is expected. Treatment conditions and treatments that do not elute alkaline components and harmful elements immobilized on the treated material out of the system even when exposed to the solution Technology disclosure is not related to the surgery.

  Furthermore, as a detoxification treatment technique for dioxins in the prior art, a detoxification technique for decomposing dioxins by heat treatment at a high temperature of 800 ° C. or higher is generally adopted. Other techniques for detoxifying dioxins include: (1) reductive decomposition with metallic sodium, (2) treatment with magnesium hydroxide as adsorbent, (3) treatment with photocatalytic silica gel, and (4) activated carbon as adsorbent. And the like are disclosed.

  However, there is no disclosure of a technique for efficiently decomposing and detoxifying dioxins at a low temperature of 100 ° C. or lower. In addition, in the prior art, a modification treatment agent composed of three members having a pH of 12 or more is added via water, using inorganic wastes and the like in which heavy metals and dioxins coexist as materials to be modified. In addition, at least at room temperature, by co-mixing multiple coexisting harmful element groups with a single agent (modifying agent) at the same time, all the harmful element groups are fixed and insoluble in water at a pH value of less than 10, and at the same time at least at room temperature. However, there is no disclosure of a processing technique for decomposing and detoxifying coexisting dioxins.

  The subject in the present invention is a heat history silicate, and the actual condition that harmful substances eluted from wastes that have been generated and treated and disposed of in large quantities have contaminated the living environment and have adversely affected humans, animals and plants. Is a technology that can cope with the toxic substances that coexist in the heat history silicate that constitutes the waste, is low environmental load type, energy consumption is energy saving type, processing process is low cost type, reforming process is executed It is in processing technology that can. In addition, in order for waste to be reformed and provided as a reusable binding shape body, it is necessary that the modified binding shape body has various physical properties to meet the needs of a wide range of application fields. There is a problem in that it is practically impossible to build a recycling society without an effective binding shape that can be safely supplied at a low price.

  In the prior art, when processing and disposing of silicate wastes, especially when trying to detoxify harmful heavy metals, which are harmful substances with which wastes coexist, and fluorine and boron at least at room temperature, Introducing multiple chemicals, modifying agents, binders and solidifying materials from outside the system to the waste to be treated, chelating treatment, neutralization / hydroxide formation treatment, coating / solidification treatment The insolubilization process with respect to a toxic substance has been performed by the above.

  For example, in the prior application technique of the present inventors (Japanese Patent Laid-Open No. 2002-128550), a large amount of 20 parts by mass or more of an antarian component made of an alkaline curing agent is added to 100 parts by mass of the material to be modified. Techniques for processing are disclosed. However, in this prior application technique, an insolubilization technique using heavy metals as elements to be insolubilized is disclosed, but there is no technical disclosure that simultaneously insolubilizes boron and fluorine, which are acid elements sufficiently soluble in strong alkali. On the other hand, in order to activate and utilize the silicate compound constituting the wastes, a modifying agent having an activation function consisting of a high alkalinity of pH 12 or higher is required.

  The first object of the present invention is to collect a group of harmful elements consisting of cadmium, arsenic, mercury, lead, chromium, selenium, boron, fluorine, etc., which are eluted from the wastes that are the materials subject to modification of the present invention.

When incorporating a harmful element group into a water-insoluble mineral, a calcium-containing component, a sodium-containing component, and a sulfur-containing component whose low alkali concentration is controlled within a range that does not inhibit the incorporation of the harmful element group into the water-insoluble mineral. The processing technology adopts a modified processing agent.

  In addition, the water-insoluble minerals incorporating the harmful element group formed here have a pH value of less than 10 that does not cause secondary pollution in the environment, and pH 4 where acid rain is assumed as well as the neutral range. It is important that insoluble treatments that do not allow water to elute toxic elements and alkali components are applied even when exposed to acidic areas, and this phenomenon makes the treated products safe and insoluble in nature for a long time. Can be ensured and maintained, and wastes coexisting with harmful elements can be effectively utilized as a bound shape body having water resistance and a pH value of less than 10.

  Furthermore, in the first problem of the present invention, not only harmful elements that are eluted from the waste that is the material to be modified, but also harmful dioxins that often coexist in the waste, at least at room temperature, By activating and utilizing the dormant component of granular wastes, insoluble treatment of harmful elements, dioxins are also decomposed at least at room temperature and detoxified, and together with harmful elements, dioxin This is a processing technology for reforming a material to be reformed at the position where at least existing coexisting wastes are present, and reforming it into a water-resistant binding shape that can be effectively used in each field.

  The second problem of the present invention is that wastes and the like mainly composed of a heat history silicate compound are used as a material to be modified, and the pH of an inert dormant component such as silica, alumina, and calcium in wastes.

It is in.

  Therefore, the object of the present invention is to provide a processing facility that enables an energy-saving reforming process step at least at room temperature in order to solve the first and second problems simultaneously at a low cost and in a low-load environment. Adopted and prepared in advance a component containing calcium, a component containing sodium oxide, a component containing sulfur, and an activated component exceeding pH 12 by managing them in a specific formulation, and the activated component is a heat history silicate. By subjecting wastes to a series of work processes that utilize them as materials to be reformed, wastes can be reformed into binder-shaped bodies with a pH value of less than 10 for recycling and disposal. The purpose of this is to provide the various wastes as recyclable materials at low cost to each field to solve the problems in environmental problems.

[Proceeding to the present invention]
The inventors of the present invention have developed a harmful element group such as boron or fluorine that is eluted in water in a large amount and is treated and disposed of, and heavy metals that are eluted simultaneously (cadmium, arsenic, mercury, Lead, chromium, selenium) and dioxins coexisting in various wastes are harmless by detoxifying them at least at room temperature with no special heat energy or expensive special equipment. Establish a reforming technology that can fix the element group to be water-insoluble not only in the neutral region but also in the acidic region, detoxify the dioxins, and provide waste as a water-resistant binding shape. This is important because it can solve the problems in environmental problems.

  For this reason, in the example of means for treating a harmful element group that is eluted from wastes with water by using conventional technology, water is insoluble. Must be used for many kinds of hazardous substances to be treated, multiple kinds of drugs must be adopted, multiple work steps are required, and the treated products must be subjected to natural environmental conditions (UV Or acid rain, etc.) and have left problems.

  In particular, when dealing with a group of harmful elements eluted from wastes by the processing method in the prior art of the present inventors (Japanese Patent Laid-Open No. 2002-128550), which is a prior art, a dormant component constituting the wastes In order to activate the silicate-based compound, for example, 100 parts by mass of the waste to be treated is treated by adding at least 20 mass of an alkaline curing agent and a large amount of an alkaline component, and waste In order to treat the harmful element group coexisting in the same group as a single element group in a lump, a treating agent composed of a large amount of alkali components has been used. In addition, there is no disclosure of technology for insolubilizing simultaneously with other heavy metals using boron, which is sufficiently soluble in a large amount of alkali, or fluorine, which is an acid element, as an element to be insolubilized.

  As a result of thorough examination of the above prior art and the like, the present inventors first made a dormancy in the mixing step of adding an alkaline component exceeding pH 12, which is a sufficient amount necessary for activating the dormant component of the material to be modified. Harmful elements eluted from the material to be modified by activating the components and consuming as much alkaline components as possible by activating dormant components to reduce the free alkali components in the system as little as possible. Effectively form water-insoluble minerals that enable the fixation and insolubilization of harmful element groups without dissolving the group, dioxins are decomposed, and at the same time, the material to be reformed is used as a recycling material in various fields In order to modify the modified material with the physical properties that can be supplied to it, a series of work steps that clarify the role assignment and amount conditions in the modifying agent are necessary. It was cross-sectional.

  In addition, the present inventors have determined that there is a problem in the technology that has uniformly processed the harmful element groups eluted from the wastes to be reformed as a collective group in the same category. Therefore, in order to cope with this problem, the present inventors classified the harmful element groups into groups according to the properties, and first examined processing techniques for each classified group. As a result, the present inventors first form a group consisting of cadmium and mercury, which are basic element groups that behave as pure basic components, and an oxo acid as a group classification of harmful element groups to be treated. It was judged appropriate to categorize into the group consisting of lead, chromium, arsenic, selenium and boron, which are oxoacid elements, and three groups consisting of fluorine, which is an acid element that acts as a halogen acid.

  The inventors of the present invention have studied and studied the fixing / insolubilization mechanism and processing conditions that can appropriately correspond to each element for each group of elements having different properties, and individually fixed / insolubilized corresponding to each group. The processing conditions were found, and the reforming conditions of the wastes by the reforming agent satisfying all the individual fixing / insolubilizing conditions were found. In particular, the present inventors have found a modification technique in which the modification effect of the present invention can effectively perform the insolubilization treatment even under conditions assuming acid rain in nature.

  Based on the above judgment, we conducted extensive studies and experiments on waste disposal technologies. As a result, the present inventors have confirmed that the group consisting of the basic components cadmium and mercury needs to form an aluminosilicate with sufficient alkalinity. On the other hand, the group consisting of lead, chromium, arsenic, selenium, and boron that form oxo acid tends to increase water solubility when it comes into contact with an excessive alkali component. It was confirmed that it was necessary to form the aluminosilicate in the presence of sufficient but not excessive alkali. Furthermore, it was confirmed that the group consisting of fluorine which is a halogen acid needs to form apatite minerals such as calcium fluoride and calcium silicofluoride in the presence of a sufficient calcium component.

  In the prior art, when a group of harmful elements coexisting in the material to be modified is insolubilized and simultaneously shaped, the components required for insolubilization and shaping are obtained from various modification treatment agents from outside the system. The material to be modified has been modified by adding and blending. The present inventors first activate the dormant component constituting the material to be modified by the free ionic sodium component, which is the modifying treatment agent, and then control the treatment agent and the blending amount of the activated dormant component The conditions for modifying the coexisting harmful element group to be water-insoluble by immobilizing the coexisting harmful element group on the water-insoluble mineral formed at a pH value of less than 10 by using the sodium component was investigated.

  However, in order to activate the inactive dormant components silica, alumina, and calcium components constituting the wastes, a sodium component exhibiting a high alkalinity of pH 12 or higher is necessary, while they are harmful metals. The group metal composed of lead, chromium, arsenic, selenium, and boron that forms oxo acid is easily dissolved in excess alkali, and these element groups cannot be insolubilized in the presence of excess alkali. Therefore, it was confirmed that satisfying the conditions for activating the inactive dormant component and the insolubilization conditions for toxic metals that form oxoacids and elute in water under the same conditions are difficult and difficult.

  Based on the above confirmation conditions, the present inventors have studied a reforming technique that satisfies the conditions for activating the inactive dormant component and the conditions for insolubilizing toxic acids that form oxo acids under the same conditions, and Alkaline components necessary to activate the dormant component of the class are used up in the activation process of the dormant component, making it an unsatisfactory condition for dissolving toxic acids that form oxo acids, Therefore, it was judged that it is important to manage the technology with a modification treatment agent that can secure an appropriate amount of alkali component with the calcium component in order to uniformly form insoluble minerals.

  As a result, the present inventors have adopted a modification treatment agent exhibiting a strong alkalinity of 12 or more at a pH value by a modification treatment operation at least at room temperature, and constitute a dormancy comprising wastes composed of heat history silicate. We have discovered a modification technology that activates and uses the silicate compounds as components in advance to immobilize all of the alkaline components coexisting as harmful substances in the system and all the harmful elements classified into three groups as water-insoluble minerals. Moreover, even if the water-insoluble mineral in which harmful substances are fixed and formed at a pH value of less than 10 is exposed not only to a neutral aqueous solvent but also to a pH 4 solution in an acidic region where acid rain is assumed, The processing conditions and the processing technology that did not elute the alkali component and harmful element group immobilized on the system out of the system were found.

  On the other hand, since the dioxins, which are harmful substances, are oily, the inventors of the present invention tend to aggregate and form oil droplets in the water component atmosphere due to the difference in surface tension when in contact with the water component. In order to disperse the dioxins having oily properties in the molecular form, the dioxins having a large surface area and high lipophilicity are first used. When it is spread in the form of molecules on the surface of the acid salt compound and the sodium ion of the decomposing agent and the oily dioxins can be contacted in the form of molecules, it can be detoxified by decomposing the dioxins even at low temperatures. I found the condition.

  In addition, the phenomenon and the condition which found the conditions which can detoxify the harmful substances at least at the above normal temperature and the conditions are the modification process which shows the alkali having a pH value of 12 or more at the same time for the granular material which is a silicate compound of wastes. It has been found that a shaping treatment can be made by modifying a water-resistant treated product that does not re-mudify in water by acting an agent. From these reforming treatment conditions, waste that coexists with hazardous substances can be provided as a non-polluting, recyclable material that can be recycled at a low cost without any special environmental impact, contributing to the resolution of environmental problems. I found a possible effect.

  In addition, although the wastes of the material subject to modification of the present invention are silicates that have received a thermal history of coexisting toxic substances with a silicate compound as the main component, the wastes found by the present inventors etc. The reforming treatment technology used as the material to be reformed is selected as a material to be reformed, a silicate compound that is a heat history silicate that does not coexist with harmful substances, and is subjected to detoxification treatment and shaping treatment. It can be provided as a material for recycling waste materials such as preference materials, living materials, industrial materials, construction / civil engineering materials, natural environment materials, or plant cultivation materials.

[Outline of the present invention]
As described above in detail in the section of the background art and the section of the process leading to the present invention, the phenomenon found by the present inventors in the present invention is the material to be insolubilized by heat history silicate that coexists with harmful substances at least at room temperature. In particular, not only the heavy metals (cadmium, arsenic, mercury, lead, chromium, selenium) in the toxic element group are not targeted for insolubilization, but boron and fluorine, which are sufficiently soluble in alkali components, are similarly insolubilized together. Utilizing a modification treatment agent having a pH of 12 or more via water at room temperature as a target element, first, an admixture step for preparing an activated admixture is performed, and then this activated admixture is subjected to at least a normal curing step. By this series of reforming methods, a working mechanism that forms a reformed product having a pH value of less than 10 due to a reaction that occurs between the material to be reformed and the reforming agent of the present invention. Is in the phenomenon shown below.

That is, the phenomenon that occurs between the material to be modified and the present modification treatment agent at least at room temperature is
1. 1. Activate silica and alumina, which are dormant components of the material to be modified, at pH 12 or higher. 2. Immobilization of harmful elements on water-insoluble minerals with a low alkaline activation component. 3. Dioxins coexisting with the material to be modified are decomposed at room temperature by molecular dispersion to make them harmless. Water-resistant water re-mudging prevention shape by binding and curing the material to be modified powder,
There are the above four phenomena, and the principle of the mechanism of the phenomenon that occurs in the technology of the present invention can be explained and understood as follows.

1. The mechanism principle that can fix the water-eluting harmful metal group coexisting in the material to be modified is that the sodium component of the present modification treatment agent activates silica, alumina, calcium, etc. that were dormant components of the material to be modified It is adjusted to a sodium amount in a range that does not dissolve the toxic metal group and acid elements that form the oxo acid that is consumed and dissolved, and activated at this time using activated silica, alumina, calcium, etc. Forms water-insoluble minerals (zeolites, zeolite precursors, etc.) consisting of alkali acid salts, and ions of the eluting hazardous metals and sodium ions are incorporated into the water-insoluble minerals, and the eluting hazardous metals and sodium metals are fixed in water-insoluble. It originates from the phenomenon that becomes. Therefore, since the coexisting alkali component is also fixed by this phenomenon, it is possible to explain the phenomenon that the formed binder is formed with a low alkalinity of a pH value of less than 10, preferably 8.6 or less. .

  In the present invention, what is important in the above phenomenon is that the amount of sodium component necessary for activating the dormant component of the material to be modified, as well as the toxic element group and acid elements that elute by forming oxo acids are dissolved. The amount of the sodium component necessary for antagonizing on the modification treatment action of the present invention, the component of the modification treatment agent is configured with sufficiently controlled contention conditions for this sodium component amount, The conditions to be used have the characteristics of the present invention and are important points.

2. The mechanism principle that dioxins coexisting in the material to be reformed can be detoxified by decomposing at least at room temperature is that dioxins are oil-based components, and sodium ions that can exert a decomposition function on dioxins are aqueous components, The oily component and the aqueous component are completely separated into two layers from the difference in interfacial tension, and generally coexist as oil droplets in the aqueous component. Therefore, simple mixing / mixing of aqueous sodium ion with resolution and oil-based dioxins makes it possible to disperse the alkaline component having a decomposing function and oil-based dioxins in molecular or colloidal contact. Is impossible.

  Therefore, the conventional decomposition mechanism of dioxins has been decomposed by spreading the dioxins in a gaseous state at a high temperature around 1000 ° C. by contact with heat or a decomposition agent. Since the present modification treatment agent is blended with lipophilic silicates as a constituent component, when the oil component coexists in the material to be reformed, the oil component is the material to be reformed or the reforming treatment. The lipophilic silicates that make up the agent spread the oily dioxins to a wide range of colloidal fine particles at room temperature, and then emulsify and disperse them in a molecular colloid with a large surface area. It can be contacted at a room temperature and can be detoxified at room temperature.

3. On the other hand, the mechanism principle that can be formed into a water-resistant solidified body having a certain strength by binding and curing the material to be reformed powder, Silica, alumina, calcium, and the like, which are dormant components, are activated to form active components with active silanol groups, and a reticulated silica polymer that forms the basic matrix skeleton of the bound shape of the present invention is produced. Next, a water-insoluble mineral composed of calcium silicate or gypsum hydrated mineral and alkali aluminosilicate was deposited and formed in the gaps between the mesh silica polymers, and the entire basic matrix skeleton was water-resistant and predetermined strength was ensured. It becomes possible to perform a modification treatment on the bound shape.

  In the reforming treatment technology of the present invention described above, the present technology can be demonstrated at least at room temperature, using a silicate that has received a heat history such as wastes coexisting with harmful substances as a material to be reformed. The prepared activated admixture is bonded and cured to the shaped processed product, and in-situ non-molded product, water-resistant granular material or shaped processed molded product, and fluidized activated admixture are prepared in advance. It has a pH of less than 10 consisting of a binder-molded active material, a base material laminated composite, a granule aggregate aggregate, or an injection-filled integrated material, which is attached to a material and applied as an adhesion-treated product and integrated with the base material to be applied. It can be set as the secured binding shape body.

  In the present specification, “normal temperature” is a temperature setting indicated in the living environment by natural weather conditions, and generally refers to a temperature in the range of 5 to 40 ° C., but the temperature range required for the technology of the present invention is normal temperature. It is not limited. In the present specification, “detoxification process” and “shaping process” are defined as follows. “Detoxification treatment” uses a modification treatment agent that exceeds 12 at a pH applied at room temperature to fix the pH value of the treated product to less than 10 to fix the coexisting elements of water-elution harmful elements. In the elution test not only in the neutral zone but also in the acidic zone (assuming acid rain), the elution of harmful metals is insolubilized within the range of the environmental standard value, and the dioxin content in the environment in terms of toxicity A state that is decomposed and detoxified within the standard value range. “Shaping treatment” refers to a state in which the material to be reformed of the granular material is shaped into a cured / solidified body that has low alkali and water resistance and is not re-mudged in water.

  Therefore, in the present specification, in order to evaluate the actual situation in which environmental pollution can be prevented even if the insolubilization treatment of harmful elements including heavy metals is exposed to not only neutral water but also acidic water by the technology of the present invention, the following is shown. The elution status of hazardous elements including heavy metals in waste and modified recycled materials is shown below by two types of elution test methods (see the section of evaluation test methods for physical properties, etc. described later) 2 It was evaluated by various analytical test methods.

1. 1. Dissolution test in neutral range: Ministry of the Environment 46 dissolution test method Dissolution test in the acidic region: Netherlands NEN7341 dissolution test method The dissolution test in the Netherlands NEN7341 which is a dissolution test in the acidic region is an evaluation method under the assumption of acid rain in exposure to nature. This product is evaluated as an accelerated test when a product that has been insolubilized with acid is exposed to nature.

  The thermal history silicate of the present invention contains at least 50% by mass of a silicate compound that exists in the original position or in the carry-in position and generally coexists with harmful substances, and the harmful chemical substances have an environmental standard value. Organic materials co-existing in the range of dry distillation ash, coal ash, incineration ash of garbage and sludge, ceramic waste, blast furnace / steel slag, sludge, bottom sediment, dehydrated cake hydrous mud From the group of soil, clay, ground, life, industry, civil engineering materials, or volcanic ejecta alone or in combination of two or more types of powder or water It can choose suitably.

  As specific examples of the heat history silicate that is the material to be modified according to the present invention, the silicic acid of the heat history silicate can be used regardless of whether the material to be reformed exists in the original position or the carry-in position. Artificial synthetic products containing at least 50% by mass of salt-based compounds, and harmful substances coexist in the range exceeding the environmental standard value, incinerated ash of organic materials such as carbonized ash, coal ash, garbage and sludge, ceramics Selected from the group consisting of sewage waste, blast furnace / steel slag, hydrous mud including sludge / sediment / dehydrated cake, soil / clay / ground, living / industrial / civil engineering materials or volcanic products Preferred examples thereof include a single granular material or a combination of two or more types of granular materials or water-containing materials. It should be noted that the material to be reformed that is the material to be reformed in the technology of the present invention is not limited to the material to be reformed in which harmful substances coexist in the range exceeding the environmental standard value.

  These wastes are discharged in a state of properties such as powder, gargle, unspecified shape, specified shape or water-containing shape. The property state suitable for the material to be modified according to the present invention is preferably a granular material or a hydrated body containing this granular material in handling. However, among the wastes, it is general wastes / industrial wastes themselves, which are pulverized, classified or primarily modified or treated by various means, granules, molded products, Aggregates of waste and radioactive waste (plate, string, lump, molded, almond, flare, sand, powder, trash, etc.), general waste / industrial waste Incineration ash obtained from incineration or dry distillation of incineration ash, etc., these types of waste can be selected according to the purpose and application.

  Of course, wastes having these other properties can be adopted after being refined and modified into powder or water-containing material in advance. In addition, these wastes often contain various kinds of contaminants, but it is preferable to remove these contaminants in advance. Further, in the material to be modified in the present invention, when the water-containing body is the material to be reformed, if the water content of the water-containing body is larger than 150 in the water content ratio, the water content is dehydrated to less than 150 as necessary. It is preferable to apply the pretreatment step for treatment in order to effectively advance the modification method.

  In addition, as silicates that have undergone other thermal histories that become the material to be modified according to the present invention, heat-resistant materials, heat-insulating materials, and heat-insulating materials that are ceramic materials such as volcanic ash and lava other than wastes Examples of such materials are industrial materials such as building materials, civil engineering materials, plant cultivation materials, and soils. These heat history silicate glass may not coexist with harmful substances, but adopting the modification treatment method modification method of the present invention as a modification target material of the present invention, the water resistance of the present invention. It can also be provided as an effective material after being modified into a bound shape.

Therefore, the time when the silicate adopted as the material to be modified according to the present invention has received a heat history is not particularly limited, for example, when the heat generated in the natural world on the earth has received a heat history in the past, Also, silicates that are the products of historical volcanic activity on the earth, or silicates whose volcanic products were deposited and weathered in the surface of the crust, in the crust, or in the sea, and are limited to their origin and timing is not.

  Generally, wastes coexist with elements such as heavy metals, dioxins, nitrogen (ammonia nitrogen, nitrate) components or ionic alkali (natrim / calcium / magnesium) components as harmful substances, These harmful substances are eluted and diffused from wastes, contaminating the living environment, and adversely affecting people, animals and plants.

  Hazardous substances that coexist in the material to be reformed consisting of the heat history silicate of the present invention are partly described in the background section above, but the Ministry of the Environment indicated in the “Survey and Countermeasure Guidelines for Soil and Groundwater Contamination”. Harmful elements (cadmium, arsenic, mercury, lead, chromium, selenium, boron, fluorine), dioxins, nitrogen (ammonia nitrogen, nitrate) components or ionic alkali (natrim, calcium, magnesium) components, etc. set to target. Contamination of harmful elements to each medium is shown in Table 1 with reference to soil elution standards, groundwater content standards, and soil content reference values indicated in the environmental standards presented by the Ministry of the Environment.

  Table 2 shows the environmental standards presented by the Ministry of the Environment for contamination of various media by dioxins. The dioxins to be treated in the present invention are generally polychlorinated dibenzopararadixins (hereinafter abbreviated as “PCDD”) having 75 isomers having oily properties, and polychlorinated dibenzofurans having 135 isomers. (Hereinafter abbreviated as “PCDF”) and coplanar PCB (hereinafter abbreviated as “PCB”).

  Incidentally, the detoxification treatment with the present modification treatment agent means that in the case of coexisting dioxins, the dioxins are chemically decomposed by the fact that the chlorine bonded to the chemical organic skeleton is separated from the organic skeleton and chemically decomposed. This is a state in which the concentration of γ is evaluated by ng-TEQ / g expressed by multiplying a conversion factor for evaluating the toxic effect, and disappears below the environmental standard value and is changed to a non-toxic compound. Table 2 shows ng-TEQ / g environmental standard values of dioxins.

  In the case of nitrogen component, it is within the range of water standards for fisheries, and in the case of alkaline component, pH is less than 10, preferably 8.6 or less, and human health is directly or indirectly secured in the living environment. It means a state in a safe environment that does not affect life. However, in the present invention, harmful standards for nitrogen components (ammonia nitrogen, nitrate nitrogen, nitrate nitrogen, etc.) are expressed as total nitrogen components, and the Japan Water Resources Conservation Association recommends the desirable elution standards for sea areas. The total nitrogen concentration of (Fisheries 3) = concentration exceeding 1 mg / L was defined as a harmful standard.

  In the present invention, the activated mixture composed of the material to be modified and the modification treatment agent is confirmed to have a pH value exceeding 12 within 3 hours at room temperature. Disperse and dissolve 5 g of the mixture in 100 cc of pure water for 30 minutes. Evaluation was made by measuring the pH value when caulking. In addition, the measurement of the pH value in the binding shape body of the present invention was similarly evaluated. The evaluation standard of the pH value evaluated here was set to less than 10 which has no risk of having a great adverse effect on the environment and biological system, and more preferably, the standard value of tap water was 8.6 or less.

  In the present specification, unless otherwise specified, harmful element groups, dioxins, nitrogen (ammonia nitrogen, nitrate nitrogen, etc.) components or water-soluble sodium components or calcium component groups alone or a plurality of harmful substances are simply “ Sometimes referred to as “toxic substances”. In the present specification, the harmful element group is a generic term including ionic fluorine / boron including heavy metals, and toxic dioxins of dioxins may be abbreviated as “DXN”.

[Aqueous solvent]
It is important to intervene with an “aqueous solvent” that activates the function of the modifying treatment agent of the present invention. The water-based solvent of the present invention includes natural water [rain water, river / lake water / pool water, spring water, well water, seawater, artificial pond / dam water, etc.], artificial water [drinking water, industrial water, agricultural water, tap water, sewerage] Treated water, industrial by-product water, industrial wastewater, domestic wastewater, treated wastewater, etc.], water content or alkali of the material to be modified [hydrous soil, sediment, soil ground, industrial waste, etc.] A single or two or more combined aqueous liquids selected from the group of salt solutions can be preferably mentioned.

  The aqueous solvent of the present invention is used when the material to be modified or the treatment agent of the present invention already retains moisture, for example, in hydrous soil, sediment, soil ground, alkali salt solution, etc. It is effective to use the water contained in the modifying treatment agent as the aqueous solvent of the present invention, and it is not necessary to add and replenish the aqueous solvent. As the general aqueous solvent of the present invention, natural water that is easily available is suitable, and water obtained from the sea, rivers, lakes and the like can be suitably selected. Of course, even when seawater is adopted as the aqueous solvent in the modification treatment agent and the modification treatment method of the present invention, the working mechanism of the modification treatment agent of the present invention is not impaired.

[Modifying agent]
The technology of the present invention uses, as a material to be reformed, a silicate containing a silicate compound, which is an inactive dormant component under heat history, as a main component. Therefore, the material to be reformed is rendered harmless by applying a reforming method at least at room temperature comprising a series of work steps in which a reforming agent having an activation function is added to the material to be reformed through water. This is a technology for performing a modification treatment into a pollution-free and water-resistant binding shape body by performing the treatment and the shaping treatment.

  Therefore, for the purpose of the technology of the present invention, silica, alumina component, calcium component, and sodium oxide that enable detoxification treatment and shaping treatment on a material to be modified consisting of wastes that coexist with harmful substances can be treated. Ingredients are not added and blended from outside the system, but they are obtained from an inactive dormant component silicate compound possessed by the material to be treated, and the dormant component silica, alumina component, calcium component and sodium oxide component The feature of the present invention is that it is activated and utilized. Therefore, the role of the modifying treatment agent that effectively and effectively exhibits the functionality capable of activating the dormant component at least at room temperature and enables detoxification treatment and shaping treatment is important.

  As described above, the modifying agent in the present technology requires a strong alkaline component to activate the dormant component of the material to be modified. However, in order to fix and insolubilize harmful element groups that coexist in the material to be modified, excess alkaline components that easily dissolve the harmful element groups are then immobilized in the expected water-insoluble minerals. It is not necessary to prepare the alkaline component, and the alkaline component contained therein is necessary but may be the minimum necessary amount, and both are in an antagonistic relationship. Therefore, it is important that the contents and amount ratio of the modifying treatment agent of the present invention are sufficiently controlled.

  That is, it is first necessary that the free ionic sodium necessary for activating the dormant component is sufficiently secured and the pH value exceeds 12. On the other hand, harmful metals (lead, chromium, selenium) and acid elements (boron, fluorine) that form oxoacids coexisting with the material to be modified tend to dissolve easily when in contact with alkali components. In order to immobilize the harmful metal group or acid element group that forms oxo acid, if there is a large amount of sodium component in the system, the immobilization of the harmful element group tends to be inhibited, and sufficient care must be taken.

  Particularly in the present invention, at least at room temperature, sodium ions are important in order to achieve the object of the present invention by effectively utilizing the components possessed by the dormant component constituting the heat history cake as the material to be modified. There is an important point where it plays a role. Therefore, in the present invention, it is important to prepare and provide an environment in which sodium ions can sufficiently play an active role, and even if there are too many or too few sodium ions when constituting the modifying treatment agent of the present invention. The object of the present invention cannot be achieved as expected.

  The modification treatment agent of the present invention is basically based on the fact that the effective component that exhibits the modification treatment function is composed of three components of calcium, sodium oxide, and sulfur oxyacid. Therefore, the sodium oxide contained in the sodium-containing component is contained in 0.1 to 5 parts by mass and the sulfur-containing component with respect to 100 parts by mass of the calcium contained in the calcium-containing component expressed in terms of the active ingredient in the dried product. The three-component component constitutes a one-pack granule with a blending ratio of 1 to 50 parts by mass of oxide in terms of oxide, and the water suspension pH of the one-pack granule exceeds 12. It is preferable that it is alkaline.

  That is, in the present invention, the modifying treatment agent may be composed of only three components of calcium oxide, sodium oxide and sulfur oxyacid which are effective components that exhibit the modifying treatment function, but contains the effective components. When a compound or composition, especially heat history silicates that are materials to be modified, such as wastes, contain these active ingredients, these active ingredients are effectively used. In some cases, the modified raw material is selected as a blended raw material.

Therefore, in the present invention, in expressing the blending content of the modifying treatment agent of the present invention, the composition of the modifying treatment agent is expressed in terms of the effective component amount of the modifying treatment agent containing only the effective component, Two cases are used in the case where the treatment agent is expressed in a solid amount composed of the total amount of raw materials including the active ingredient constituting the treatment agent. For example (see Table 7 of Reference Example 1 described later), for example, 100 parts by mass of blast furnace slag containing 46.7% by mass of calcium as an active ingredient and baux red mud containing 2.54% by mass of sodium oxide as an active ingredient When 100 parts by mass of the solid modification treatment agent is configured, the quantity of solid treatment is 100 + 100 = 200 parts by mass of the modification treatment agent, but the converted amount of the active ingredient is 46.7 + 2.54 = 49.24. It becomes a mass part. In the present specification, when the amount of the raw material for the modification treatment agent is indicated, the claim is unified with the numerical value of the effective component conversion amount. On the other hand, in the examples, in order to clarify the actual composition, it was expressed by a numerical value of the solid amount, the active ingredient content contained in the reforming agent raw material was shown separately, and the compounding quantity conversion with the effective ingredient quantity was made possible.

  In the modification treatment agent of the present invention, when the amount of sodium oxide, which is an active ingredient contained in the sodium-containing component, is less than 0.1 part by mass with respect to 100 parts by mass of the active ingredient contained in the calcium-containing component, It is not preferable because the activation power of sodium ions in the quality treatment agent tends to be insufficient. Therefore, the blending amount of the sodium oxide component in the modifying treatment agent needs to be blended in a sufficient amount so that the dormant component can be activated at least at room temperature.

  On the other hand, when more than 5 parts by mass of the sodium oxide component, which is an active ingredient, is added, activation of sodium ions in the activated admixture formed through the water with the material to be modified and the modifying treatment agent in the system In the formation of water-insoluble minerals that are too powerful and then formed, the group consisting of lead, chromium, arsenic, selenium and boron, which are highly soluble in alkaline components, and also acid elements that are halogen acids Certain fluorine is not preferable because it easily dissolves with sodium ions and tends to be difficult to fix to the water-insoluble mineral formed.

  In the modification treatment agent of the present invention, when sulfur, which is an active ingredient contained in a sulfur-containing component, is less than 1 part by mass in terms of oxide with respect to 100 parts by mass of calcia, which is an active ingredient contained in a calcium-containing component, The co-mixed calcium ions are neutralized in the next step, and the formation of hydrated minerals necessary for matrix formation is insufficient, and the formation matrix cannot be expected to have a predetermined strength. On the other hand, when the sulfur oxide component is more than 50 parts by mass, it tends to be difficult to ensure the water suspension pH value of the modifying agent to 12 or more, and the dormant component of the material to be modified is activated. Therefore, it is not preferable that sodium ions and calcium ions necessary for the treatment are quickly neutralized and inactivated.

It is preferable because it is inexpensive and available. However, calcium oxide (quick lime: calcium oxide) reacts violently with water to generate a large amount of heat (15540 cal. Per mole), and easily reacts with water and carbonic acid in the air atmosphere to produce carbonic acid. It is necessary to pay close attention to the blending of the modification treatment agent because it changes into a salt or a hydroxide and impairs the storage stability of the modification treatment agent.

  In addition, the calcium component may coexist with the alkaline earth metals magnesium, zinc, strontium, and barium elements, which are the elements of the calcium and the same family, and the basic component of the present invention as long as it is mixed in an amount of 10% by mass or less.

On the other hand, a granular material in which a sodium component composed of a combination with, for example, active sodium hydroxide having free ionic sodium is added and blended in an amount of 3 parts by mass or less is preferable. Further, water is added to the granular material in which the sodium component is added to the calcium-containing dormant component and added in an amount of 450 parts by mass or less to ensure free ionic sodium, and the water suspension pH value exceeds 12.

Is very preferable. In the case of sodium sulfate, calcium ions of the calcium-containing component to be blended together with sulfate radicals react in advance to form free sodium ions in the calcium ions.

  Furthermore, another specific example of the sodium-containing component is sodium chloride (salt) which is a halogen compound. Of course, even if chlorine, which is a halogen, is mixed in the modifying treatment agent of the present invention, the action mechanism of the present invention is not essentially inhibited. However, it may not be preferable in the case where the formed binding body is in contact with a metal such as iron. The sodium-containing component of the present invention may coexist with potassium or lithium, which is the same element as the sodium element. The coexistence of potassium and lithium in the sodium salt compound basically does not hinder the treatment function of the treatment material of the present invention.

  The processing step of processing the activated admixture into a substrate-adhesive-type adhering treatment product is performed by spreading a fluidly activated admixture prepared in advance on the surface of the application target substrate in a predetermined amount ratio, Substrate-attached active powder binder integrated with base material for application according to purpose and application by processing means consisting of consolidation, binding, adhesion, coating, lamination, assembly or injection This is a process for preparing an adhesion-treated product consisting of a product, a granule aggregate, or an injection-filled integrated product.

  Therefore, the reforming treatment method of the present invention uses a heat history silicate as a material to be reformed, immobilizes the alkaline component of the fluid activated admixture prepared by the above-described series of work steps, and has a pH of less than 10. When a harmful substance coexists in the material to be modified, a detoxification treatment is performed to fix and insolubilize the harmful substance, and at the same time, the heat history silicate of the granular material is made water-resistant and not re-mudged in water Treatment to improve the self-contained binding shape body, or to modify the base adhesion type binding shape body integrated with the application target base material A method is provided.

  In general, the mixing process that constitutes a series of work steps in the reforming treatment method of the present invention is a heat history mainly composed of a silicate compound that is a dormant component at the original position or the carry-in position where the material to be modified exists. For the material to be modified consisting of a silicate granular material or a hydrous material, a modification treatment agent in which free ionic sodium is secured via an aqueous solvent and has a pH value of 12 or more, if necessary, a function-imparting agent It is a process of adding and mixing to make an activated mixture.

  Next, the processing steps constituting a series of work steps are applied to the application target substrate prepared in advance, or the processing step of converting the activated admixture into a shaped processed product by various shaping processing means and methods as necessary. -It is a processing step to make an adhesion treated product integrated with the base material to be applied by binding, covering and integrating.

  Next, the curing process that constitutes a series of work processes is based on the three processes of the curing process in which the activated admixture, the shaped processed product, or the attached processed product is released to at least a normal temperature atmosphere to react and cure. By applying a series of work steps, the alkaline component of the activated admixture is fixed to ensure a pH of less than 10, and when harmful substances coexist in the material to be modified, the harmful substances are fixed and insolubilized. At the same time, the heat history silicate of the granular material is shaped to be water-resistant and not re-mudged in water, and reformed into a recycled material that is a self-contained or base-attached binding shape It is a process to do.

  The activated admixture prepared by the technique of the present invention is prepared by adding a heat treating silicate with a modifying agent having a pH value exceeding 12 and, if necessary, a function-imparting agent and an aqueous solvent. It is necessary to add / supplement a function-imparting agent as a supplementary component according to the use and workability, and to meet the needs from each field. The function-imparting agent, which is a supplementary component, can be made into an activated admixture as a whole by adopting it as a one-pack in addition to the modifying treatment agent in advance. It is also possible to prepare an activated admixture by adopting only the treatment agent, and then prepare a multi-stage compounded admixture in which a function-imparting agent is added to the activated admixture and mixed.

  Further, in the modification treatment method of the present invention, the processing for shaping the activated admixture itself prepared by adding the modification treatment agent and, if necessary, the function-imparting agent to the heat history silicate and the aqueous solvent, is performed. A modification treatment method for subjecting a shaped treatment product to a curing process, and a modification treatment for subjecting an adhesion treatment product to a curing step by a processing step for adhering the activated admixture to a substrate to be applied prepared in advance. There are two types of modification treatment methods.

  The basic mixing step in the series of work steps of the present invention is a reforming treatment in which free ionic sodium is secured and the pH value exceeds 12 with respect to 100 parts by mass of the material to be modified according to the present invention on a dry matter basis. 2 or less than 20 parts by weight of the agent, and if necessary, the amount of the function-imparting agent composed of one or more of the function-imparting agents composed of supplement, improvement, functionment or rain reinforcement is 400 parts by mass or less. In addition, or the reforming agent and the function-imparting agent are added in one pack by a batch method, and an aqueous solvent is added as necessary to maintain the moisture content in the range of 10 to 70% by mass at room temperature. A pH value of 12 is ensured in a range not exceeding 3 hours, and the mixture is homogeneously mixed, with a frustration, plastic, mayonnaise, paste or slurry. A step of preparing a blend.

  What is important in the blending process of the present invention is that the material to be modified composed of the dormant component of the present invention is expressed on a dry matter basis, and free ionic sodium is secured for 100 parts by mass, so that the pH value is 12. More than 2 to less than 20 parts by weight of the modifier is added to prepare a homogeneous activated blend. If the amount of the modifying agent added at this time is less than 2 parts by mass, the active silica and alumina necessary for the modifying treatment of the present invention cannot be obtained. Moreover, when the amount ratio of the modifying treatment agent to be added exceeds 20 parts by mass, there are many alkali components in the mixture system, and excessive ionic sodium is left in the mixture after activation. It is necessary to be careful because it tends to hinder the immobilization conditions of harmful element groups.

  The properties of the activated admixture prepared in the blending process of the present invention vary depending on the amount of water contained in the material or the amount of aqueous solvent added at the same time. It can be prepared into an activated admixture consisting of plastic, mayonnaise, fluid or dispersion. Of course, it is necessary to pay close attention to the fact that the same modification treatment agent shows different activated admixture states depending on the composition content of the material to be modified, how to receive the heat history, and the process after receiving the heat history. Therefore, it is necessary to confirm the mixing conditions in the mixing process by a preliminary experiment.

  In the mixing step of the present invention, when the activated admixture is mixed and allowed to stand at room temperature for at least 3 hours, the initial pH value of the activated admixture exceeds 12 from the high value, and a dormancy composed of an alkaline component and a silicate compound, etc. The progress of the activation reaction can be confirmed from the phenomenon that the pH value of the admixture drops below 12 due to the activation reaction with the components. When the pH value of the activated admixture is higher than 12 after 3 hours from the preparation of the activated admixture, the activated admixture with the higher pH value is used in the next step. It is difficult to complete the fixation and insolubilization of harmful elements even if they are brought into a certain curing process and proceed with reaction and curing.

Multi-stage In addition, in the blending process of the present invention, activation is performed by adding a function-imparting agent, which is a supplementary component, to the activated blend obtained by adding a modification treatment agent to the material to be modified in advance according to the purpose and application. An admixture can be prepared. The amount of supplemental components added to the activated admixture at this time is 400 masses of the function-imparting agent according to the purpose, application, workability, etc. with respect to 100 mass parts of the material to be modified, expressed on a dry matter basis. It is preferable to add in an amount of no more than parts. Of course, since it varies greatly depending on the type and combination of the function-imparting agents to be adopted at this time, the purpose / use, and workability, it is preferable to determine the blending conditions and the like through preliminary experiments conducted in advance.

  In the blending process of the present invention, the condition of mixing and leaving the activated blend obtained by adding the modifying treatment agent to the material to be modified at room temperature for at least 3 hours is continued for 3 hours continuously. However, after it has been confirmed that the activated admixture obtained by adding the modifying agent to the material to be modified is in a homogeneous state, the mixing means is stopped and the mixture is simply left at room temperature. However, the activating action is continued and the mixing step suitable for the purpose of the present invention can be completed.

  The general mixing means for preparing the activated admixture in the mixing step of the present invention varies depending on the place where the series of working steps are carried out, the working conditions, the purpose and use, etc., but generally this industry (food industry, (Chemical industry, ceramic industry, civil engineering / architecture industry, agricultural and civil engineering industry, etc.) known and publicly used mixers, kneaders, agitators, excavators, mixers, reactors, dispersers, stabilizers, ground improvement devices Adopted at the processing site of secondary products such as cement milk, concrete and ceramic products, etc., which are capable of homogeneous mixing such as cement solidifying material mixers, agricultural cultivators, etc. Each admixture of the present invention can be suitably recovered by appropriately adopting and operating a mixer, a kneader or the like.

  In addition, as a comparative example of the technology of the present invention, four types of comparative example components (comparative sample numbers H-01 to 04) shown in Reference Example 4 were selected in comparison with the modified treatment agent of the present invention. Subsequently, Portland cement (JIS R 5210, sample number: H-5), which is a conventional general-purpose solidifying material, and water glass composition in which a hardener aluminum phosphate is added to No. 2 water glass, which is a general-purpose water glass-based solidifying material.

[Example 16] Contaminated soil In this example, contaminated soil of soil ground contaminated with multiple heavy metals is selected as a reforming treatment material, and a modifying treatment agent is mixed with the contaminated soil through water. A water-resistant bonded shaped body, which is an in-situ non-molded product in which heavy metals are fixed and insolubilized by a reforming method consisting of a series of work steps and detoxified, will be described.

As the modification treatment agent in this example, the modification treatment agent (sample number A-05) shown in Reference Example 2 was selected. Well water was selected as the aqueous solvent adopted in this example.
Moreover, as a comparative example for comparing the present invention with the prior art, commercially available Portland cement was selected as a comparative modification treatment agent.

  In this example, the contaminated soil used as the reforming material is contaminated soil [soil A and soil B] contaminated with a plurality of heavy metals [cadmium, lead, arsenic chromium, mercury] collected from two sites of the chemical factory. I chose. The main components of soil A and soil B [mass% based on dry matter] and the concentrations of coexisting heavy metals (mg / kg) are also shown in Table 44. Table 46 also shows the results of the pH 7 dissolution test and the pH 4 dissolution test on soil A and soil B in an untreated state.

  In the mixing process in the in-situ non-molded product in which heavy metals coexisting in the contaminated soil are fixed, insolubilized and rendered innocuous, the blending ratio shown in Table 47 with respect to the contaminated soil of the modified material Then, the modification treatment agent (A-05) and an aqueous solvent (well water) are added, and the mixture is stirred using a mortar mixer for testing the mixing and mixing apparatus [Mighty 30 (capacity 20 liters: stirring 60 rpm): Aikosha Seisakusho Co., Ltd.]. The mixture was mixed into a plastic mixture. The mixture is then subjected to a curing process in which it is left in the original atmosphere, the mixture is placed in a sealed container, left at room temperature (about 25 ° C.) for 3 days, and then left for 2 months. It was used as an analytical sample for elution testing of heavy metals as molded products.

  Further, Portland cement, which is a comparative modification treatment agent, was mixed in the blending ratio shown in Table 47 for the contaminated soil A and the contaminated soil B by the same modification method as the detoxification treatment of this example. The mixture was placed in a sealed container, left at room temperature for 3 days, and left for 2 months. After sampling, it was sampled as a sample for heavy metal dissolution test analysis.

In order to confirm the evaluation of physical properties of the samples subjected to the detoxification treatment in this example, dissolution tests (mg / L) of heavy metals at pH 7 and pH 4 were performed, and the results are shown in Tables 48 and 49. Further, tests were conducted on simple deformability and water elution pH by a simple deformability measurement test [q = KN / m ² ], and the results are also shown in Table 50.

  As a result of the above, contaminated soil from which harmful heavy metals are eluted exceeding the environmental standards is modified in situ using the modified treatment agent of the present invention, and the contaminated soil is detoxified at room temperature. In this case, the coexisting multiple heavy metals are simultaneously detoxified within the range of the environmental standard by the reforming treatment method of the present invention, and the heavy metals immobilized in the pH 4 solution assuming acid rain do not elute, It is well understood that the treated soil is an in-situ water-resistant unmolded product with a water elution pH of less than 10, and can be immediately reused on treated soil ground that is not concreted.

  However, when treating contaminated soil with cement in the prior art, the pH value of the contaminated soil is alkaline, even if it is possible to temporarily cover the coexisting heavy metals, and the heavy metals are fixed particularly in the acidic range. -If it cannot be insolubilized and left for a long period (two months), heavy metals will elute into the environment and will exceed the environmental standards. Unlike the technology of the present invention, heavy metals coexisting with contaminated soil will be used in cement. It cannot be insolubilized safely.

A water-resistant binder-shaped body that has been insolubilized by detoxification is described.

  As the modification treatment agent in this example, the modification treatment agent (sample number A-05) shown in Reference Example 2 was selected. The water-based solvent adopted in this example used water from a nearby river. In this example, the contaminated soil used as the modified material is contaminated soil contaminated with multiple heavy metals [cadmium, lead, arsenic chromium, mercury] collected from the site of the chemical factory [soil C ground: 10 m × 30 m × Depth 2m] was selected. Table 51 shows the main component [mass% based on dry matter] and the concentration of heavy metals [mg / kg] contained in the average value of the analysis results of the sampling soil collected from the soil C ground area. Moreover, the elution test of pH7 and pH4 of heavy metals in the untreated soil C was conducted, and the results are shown together in Table 52.

  In the mixing process of the work process of fixing and insolubilizing the coexisting heavy metals in the in situ contaminated soil ground using the modified treatment agent of the present invention, the “self-propelled type” is a mixing apparatus widely used for ground improvement in the civil engineering industry. Two methods were adopted: “Soil Improvement Method” and “Backhoe Stirring Method”.

For the improvement of contaminated soil using the “Self-propelled soil improvement method” in the mixing process, the RETERRA equipment [manufactured by Komatsu: rated output 107 KW / 195 rpm, mixing method: soil cutter + 3-axis large rotary hammer + aftercutter] Installed on the ground, put the contaminated soil mined in-situ into the installed RETERRA equipment, and apply the modified treatment agent at a mixing ratio of 100 kg of the modified treatment agent (A-09) to 1 m ^{3 of} the introduced contaminated soil. In addition, about 80 to 100 kg of river water is added to 1 m ³ of contaminated soil and mixed continuously. The mixture is returned to the mining site and left at room temperature for 3 days. In the curing process, the coexisting heavy metals were fixed and insolubilized and detoxified.

Modification of contaminated soil in the "backhoe stirring method" mixing step, backhoe implement [Komatsu Seisakusho, Kyatabira movable flat product: piling at 0.6 m ^3: it is supplied with a stirrer 0.8 m ³ volume of the bucket bringing it has] a local, previously contaminated with respect to soil 1m ³ depth capacity assuming the depth 1m soil ground, in addition to modifying agent in a proportion of the modifying treatment agent 100 kg, further river water against the contaminated soil 1 m ^3, uniformly and intimately with backhoe added about 80 or 100 kg, subjected to curing step of standing 3 days admixed an original position, detoxification and allowed fixing and insolubilizing the coexistence heavy metals Went.

  In this example, in order to confirm the physical property evaluation of the non-molded processed material detoxified by the “self-propelled soil improvement method” and the “backhoe stirring method” at the normal temperature of the contaminated soil ground, The elution amount (mg / L) of heavy metals was measured by the dissolution test of heavy metals described in the section at pH 7 and pH 4, and the results are also shown in Table 53.

  As a result of the above, in the original position of the soil ground contaminated with a plurality of heavy metals, the modified treatment agent of the present invention enables a series of work processes at room temperature by the “self-propelled soil improvement method” and the “backhoe stirring method”. It is well understood that the coexisting heavy metals are detoxified at the same time, and the contaminated soil ground is restored to a reusable ground condition at low cost in situ

The water-resistant binding shape body prepared by capturing and decomposing the contained dioxins by the above-mentioned work process and making it non-polluting treatment and treating it will be described.

  The contaminated soil [soil D] contaminated with dioxins collected from the rubbish incineration site was selected as the contaminated soil of the modified material in this example. The contamination status of dioxins in soil D was determined by measuring the concentration of contained dioxins according to the simple analytical measurement method described in the section of physical property evaluation test method, and the results are shown in Table 54 as pg-TEQ / g concentration.

The above “Note” is common to the following analysis result tables.

  As the modification treatment agent in this example, the modification treatment agent (sample number A-05) shown in Reference Example 2 was selected. River water was used as the aqueous solvent. A series of work steps for capturing and decomposing dioxins by the modifying treatment agent is for a test mixing device with a mixing ratio of 20 parts by mass of the modifying treatment agent and 20 parts by mass of water with respect to 100 parts by mass of the contaminated soil. A mortar mixer [Mighty 30 (capacity 20 liters: stirring 60 rpm): Aikosha Seisakusho Co., Ltd.] was taken, mixed and integrated by stirring and mixing, and subjected to a mixing step to make a plastic mixture with Basabasa.

  Next, the mixture is divided into two without special molding, and each mixture is subjected to two different curing processes (room temperature curing process or heat curing process) to decompose dioxins coexisting in the contaminated soil. Detoxification treatment was performed. In the room temperature curing process, the mixture is opened to room temperature in the atmosphere (during the test period: average of about 20 ° C.) and left for at least 7 days, and the treated soil is dehydrated to a moisture content of 5% by mass or less. It collect | recovered as normal temperature processing soil. In the heat curing process, the mixture is opened to room temperature in the atmosphere (during the test period: average of about 20 ° C.) and left for at least 3 days, and then exposed to 100 ° C. for about 30 minutes for dehydration treatment. The treated soil that had been dehydrated was collected.

The dioxins concentration in the 3-day soil that was collected here and the heat-dehydrated soil was analyzed and measured by the “Simple Analytical Measurement Method” shown in the Physical Properties Evaluation Test Method section. Table 55 shows the case of treated soil that was further heat dehydrated. Furthermore, tests were performed on simple deformability by the simple deformability measurement test [q = KN / m ² ] and water elution pH in the treated soil A and the treated soil B, and the results are also shown in Table 57.

  As a result of the above, the contaminated soil containing dioxins was started in-situ with the modifying treatment agent of the present invention in water and made into an admixture. Dioxins contained in contaminated soil are captured and decomposed and reduced to below the environmental standard by subjecting them to a reforming process that keeps the water content as close to zero as possible without processing at high temperatures that require a lot of energy. It has been detoxified and reformed to treated soil made of detoxified substances, and it is often better to detoxify contaminated materials that are contaminated with dioxins at low cost without causing any special environmental impact.

The modified treatment agent was selected. As the hydrous soil soft ground which is the modified material adopted in this example, a soft ground with a water content of 30% by mass in Miwa Town, Ibaraki Prefecture was selected.

The reforming and reinforcing treatment at the soft ground in situ is an amount equivalent to 150 kg with respect to 1 m ^{3 of the} in situ soft ground under pressure by a chemical mixing and stirring type deep mixing device that is widely used for soil improvement in the civil engineering industry. The slurry of the modification treatment agent is injected and stirred, and the slurry-like modification treatment agent is homogeneously mixed into the ground up to 4 m below the soft ground by an injection and stirring method to obtain an admixture, and then cured in situ for 7 days. The soil of the modified reinforced ground was sampled and the physical properties were evaluated.

As a result, the uniaxial compressive strength of the soft ground subjected to the modification reinforcement treatment was 250 KN / m ² or more, and the water elution pH was 9.5 or less. As a result of the above, without introducing harmful chromium into the soft ground by cement, the slurry-like reforming agent of the present example is injected into the soft ground in the in-situ mixture and mixed to form a pile that gives reinforcement to the soft ground. It is understood that the ground is being reinforced.

A water-resistant binder-shaped body that has been processed and modified into a structure or a granule by adding a treatment agent and performing a shaping treatment and a detoxification treatment by the modification treatment method of the present invention will be described.

  As a reforming treatment material, sediment collected from the sea area [Ago Bay] [water content ratio: about 158, water content: 59.5%, particle size composition: clay 63, silt 24, sand 10, gravel 3%] I chose. As the modifying agent, the modifying agent shown in Table 60 was selected from those shown in Reference Example 2.

  The treatment test specimen using the bottom sediment in this example as the reforming treatment material was modified to the bottom sediment adjusted in the water content ratio at the blending ratio shown in Table 58 in accordance with the method described in the physical property evaluation test method. Seawater containing a treatment agent was mixed and integrated as an aqueous solvent to obtain a plastic mixture. Next, the mixture is molded into a cylindrical test body (structure) and left in the air at room temperature (about 25 ° C.) for 2 months. The mixture is formed into an about 7 mmφ granular test body (granule). Water resistance that can be provided as an adhesive shaped body by a modification method of a modification treatment agent that is granulated and left in the air for 24 hours and then left in seawater for 2 months to make the bottom structure or structure.

The results are also shown in Table 59. In addition, in the granular test body (granular body), a granule obtained by drying a granule cured underwater for 2 months at room temperature for 48 hours was used as a test body for evaluating physical properties.

  In Table 62, “Water quality standards for fisheries products” are listed as [preferred water quality standards in the water areas published by the Japan Fisheries Protection Association, although there is no legally established water quality standard for aquatic products] The elution amount of total nitrogen is shown for reference.

  As a result of the above, reforming agents prepared using sea bottom sediments as raw materials for reforming treatments, and reforming materials prepared using sea bottom sediments as raw materials for reforming treatments against the bottom sediments of sea areas selected as reforming raw materials. By processing in a series of work steps with the modified treatment agent of the present invention including the treatment agent and in the curing process in the sea, the solidified body having a water elution pH of 10 or less and the solidified body strength not to be re-mudged with granules are obtained.

[Example 22] Granule group aggregated product is a scalloped shape In this example, a paste-like or plastic flow prepared in advance with respect to a granule group which is an aggregate of various granular or aggregated granules The surface of the granule group is wetted with the adsorbent mixture to form a heterogeneous film, and the granules are adhered to each other. At this time, the aggregate of the granule group is made to have a penetrating void, and the granule group is shaped like a sorghum. The water-resistant bound-shaped body, which is an aggregate product of granule aggregates that are assembled and integrated together, will be described.

Choose a spherical, hollow, cylindrical, flake, granule with a granular or aggregate particle size of 2-12mmφ and a bulk density of 0.2-3.5g / cc, or unspecified granularity Commercial pearlite grains with a bulk density of 0.5-0.6 (g / cc) that are sized from 2 to 8 mm from the body [lightweight inorganic in which obsidian is rapidly heated at 800-1200 ° C. and volume expanded. It was selected from a granular material (sample number FC-08) and a glass cullet (sample number FC-11). The paste-like or plastic fluid mixture for integrating the granule mass into the cocoon-like aggregate was selected from the fluid mixture shown in Reference Example 2.

  About 5 kg of water is added to 10 kg of the selected granule group, and the surface of the granule group is wetted. Then, 15 kg of an adhesive paste is added to cover the entire surface of the granule group and the granule group is integrated as an aggregate. The granule group is cast into a 300 × 300 mm mold having a thickness of 30 mm, allowed to stand at room temperature for at least 48 hours and cured, and then demolded to form a granule group aggregate shaped product that is an agglomerated aggregate shaped product. A water-resistant binder shaped body was prepared.

  Based on the description of the physical property evaluation test method, the water resistance and heat resistance were confirmed and the water elution pH was measured. In addition, in order to confirm the penetrability of each cocoon-like granule aggregate assembly, water is dropped on the discoid coconut-like granule aggregate assembly, and water flows into the lower part of the coconut-like granule aggregate assembly. The penetrability was confirmed by this method. These results are shown in Table 63.

  As a result of the above, the granule aggregate assembly processed and prepared in this example is water-resistant and heat-resistant, has a low alkalinity of less than pH 10, and has a through-hole as necessary.

A description will be given of a water-resistant binder-shaped body composed of an integrated product obtained by injecting and filling a modification treatment agent and mixing and integrating a gang-like aggregate group and a slurry modification treatment agent in a container.

  In the present embodiment, the crumb assembly as a modified material is pressed into 30 × 20 × 15 mm almonds of sodium sulfate (sodium nitrate) powder, which is stored in a 200L drum lined with special cement. We chose a jumbled group consisting of molded tablet ellipsoidal spheres. The modification treatment agent in this example is selected from those shown in Reference Example 2, and the function-imparting agents are the silicon phosphate (FI-01) and barium silicate (FI) which are the improvements shown in Reference Examples 6 to 7. -07) etc. were selected in advance to select a modification treatment agent capable of adjusting the working life of the slurry-like modification treatment agent and the curing time.

  A slurry-like admixture in which 90 kg of tap water was added to 100 kg of the slurry-like modifying treatment agent and dispersed was selected. The fluidity of the slurry-like admixture prepared here was measured as a viscosity within a certain time range, and the continuity of the integrated work for injecting the slurry-like admixture into the garactor assembly container was confirmed. The viscosity of the fluid admixture of this example was measured by adding 35 ° C. water to the powdery reforming agent maintained at 30 ° C. at a predetermined ratio and stirring the prepared fluid admixture at 52 ° C. The viscosity of the mixture after 60 minutes was measured with a C-type viscometer, and the results are shown in Table 65 as CP [centipoise].

  In this example, the limit paste viscosity that enables injection integration without leaving any voids in the container is set so that the paste viscosity after 10 minutes of slurry modification treatment agent preparation does not exceed 8000 CP, and one of the operations is possible. The pot life was set to 1 hour, and the viscosity of the paste not exceeding 20,000 CP in the range of 1 hour was set as a condition for ensuring good workability.

  Into a 200L drum can containing 260kg of almond-like salt cake that has been compressed into tablets, 110kg of the above slurrying modifier is poured and filled in 10 minutes so as not to leave a void in the drum can. Then, it was allowed to stand at room temperature for 28 days and poured and filled to prepare an integrated product. At this time, the cylindrically modified test specimens were prepared at the same time in accordance with the physical property evaluation test method shown in this specification, and the slurry-like modifying agent adopted at this time was allowed to stand for 28 days at room temperature (about 25 ° C.). The physical properties of the prepared cylindrical processed specimen were evaluated by measuring water resistance and water elution pH. The results are also shown in Table 66.

  As a result of the above, a slurry-like reforming agent with a fixed injection fluidity is injected and filled into a drum container containing a reforming material having a certain porosity in a group of almond-like sodium sulfate aggregates. When an integrated product is obtained, it is understood that the aggregated body of almond-like sodium sulfate is prepared into a water-resistant binding-shaped product made of an integrated product that does not scatter.

  According to the present invention, various problems that have been encountered with conventional hydraulic solidification materials that can be applied at normal temperature are solved, and a low-cost and versatile hydraulic property-modifying treatment agent is produced without giving an environmental load. Because it is possible to utilize the reforming processing function (detoxification function and shaping function) of the reforming agent, wastes that coexist with harmful substances can be used as an energy-saving type reforming material. Since it is possible to provide water-resistant binders that can be effectively recycled and reused for civil engineering materials and general use materials as recycling materials, there is a great potential for use and utilization in industrial fields that handle waste in particular. There is great potential for solving problems and building a recycling-oriented society.

  Remediate treatment of water-containing sediments, sewage sludge cake, incinerated ash, contaminated soil / farmland, soft ground, junk waste, etc., which are typical wastes that need to be treated and disposed of in the living environment As a material, it can be recycled and recycled by a simple reforming method consisting of a series of work processes according to the present invention that can be safely processed and disposed of at low cost without giving a special load to the environment. The outline of a typical bonded shape body of the present invention that can be provided as a chemical material is described below.

1. In the case of recycling of hydrous sediments,
The sediments at the bottom of closed waters such as closed seas, rivers, lakes, and dams coexist with heavy metals and dioxins due to today's environmental conditions, and also have an impact on ecosystems and the environment due to toxic substances along with hypoxia.

However, according to the reforming method using the reforming material of the present invention, the moisture content of the dredged sediment at the bottom of the water area is preferably adjusted to dehydration to 150 or less, and the content corresponding to 100 parts by mass on the dry matter basis is included. 10 to 30 parts by mass of the modified material of the present invention is added to the bottom sediment and mixed to obtain an admixture.

Next, when the shaped product formed into granules or the like is left open and cured in the air or water, the heavy metals coexisting at a pH value of less than 10 are fixed and insolubilized at least after 7 days. Dioxins are decomposed and detoxified, and formed into a shaped product with a uniaxial compressive strength of 500 KN / m ² or more, which does not create an anoxic state and does not re-mudder (use: It can be provided as a pollution-free adhesive shape body made of a reef, a bottom forming material, an embankment material, an intermediate material, a sand covering material, a building material, a banking material, a planting soil material, or the like.

  However, if the modified treatment method of the present invention is utilized, the modified sludge is added to the hydrated sludge by first adding incinerated ash having the ability to carry water to adjust the moisture content, thereby forming the hydrated sludge. By using the dormant component, the coexisting heavy metals are fixed and insolubilized, deodorized and deodorized by deodorizing, and if necessary, other organic materials and organic waste are added to compost and granulate or As recyclable materials made of granules, it can be effectively provided at low cost for soil for planting, greening base material, lawn earth material, soil improvement / modification material, and the like.

3. In case of detoxification treatment of toxic substance coexisting incineration ash Incineration ash of general waste / industrial waste and sludge and fly ash ash discharged from thermal power plants are hazardous heavy metals and dioxins In general, it is partly reused as a substitute for civil engineering materials by treating it with molten slag at 1400 ° C. with some expensive equipment, and as a secondary material for cement. However, most are landfilled in controlled areas. However, the number of landfill sites is decreasing rapidly, and life-prolonging measures have been taken, but there is no drastic solution.

  However, if the reforming treatment method of the present invention is utilized, first, the coexisting harmful substance group is detoxified by the self-contained reforming processing means utilizing the dormant component constituting the incinerated ash, and simultaneously shaped.

5. In the case of reinforcement and reforming treatment that does not place a burden on the environment of soft ground When attempting to secure a certain level of strength in landfills or inherently soft ground, conventional ground improvement has been carried out using cement as a modification treatment agent.
