Description

[0001]
OBJECT OF THE INVENTION
    The present invention relates to a technology that enables high-density accumulation of garbage stacked in a large amount in a final disposal site for wastes such as a stable disposal site, a management-type disposal site, and a closed-type disposal site, Prevents stormy dust from being scattered in the surrounding area, prevents rainwater and associated running water from entering and flowing out of the collected garbage, and collects garbage from wild birds and other wild animals. It is an object of the present invention to provide a novel film forming method for a waste disposal site that can prevent the generation of a waste film and a waste coating layer having a novel structure using the same.
[0002]
[Prior art]
    The industry and economy in Japan have continued to make great strides based on technological sophistication, but the industrial structure and lifestyle cannot be considered as a waste treatment process, It must be said that the administration and the people's consciousness of daily life have all become a mass-consuming society with increased waste, and the amount of waste generated every day depends on the municipality. It is collected for each area, transported to incineration facilities or recycling facilities as appropriate, and further treated and disposed of as incineration ash and incombustible waste. Ensuring the final disposal site is the biggest issue.
[0003]
    Particularly in large metropolitan areas, it is extremely difficult to secure disposal sites in the surrounding municipalities, and it is necessary to transport waste to remote private disposal sites beyond neighboring prefectures. The shortage of final disposal sites has become a major social problem, such as illegal dumping by contractors. In order to solve these issues, waste collection and recycling have been actively carried out in recent years, and the amount of garbage has been gradually reduced, but there is still a shortage of final disposal sites. The current situation is that new disposal sites must be built one after another on the beaches and mountain valleys where nature is abundant, and criticism of natural destruction by the final disposal site has increased. And the momentum to protect the rare nature is gradually increasing.
[0004]
    In the final disposal site with these various problems, cyanide, arsenic, etc. from the stable disposal site where only the so-called five stable items such as rubber waste, metal waste, glass, ceramic waste, waste plastic and construction waste should be dumped. Examples of toxic substances and sewage that have flowed out are unending, and new issues have arisen that the introduction of malicious industrial waste has not been completely prevented. At the disposal site, there is concern about soil contamination in the leachate and the downstream area of the river, and in unburned waste, the scatter of trash, odors, generation of toxic gases, wild nature such as crows and wild mice, etc. due to wind. The possibility of damaging the natural environment and adverse effects on the living environment of local residents, such as scattering by animals and the occurrence of large numbers of flies, cannot be denied.
[0005]
    As a technology to solve such problems at the final disposal site, after the daily dumping work has already been completed, covering the entire surface of the waste at the disposal site so that it covers the waterproof synthetic resin sheet. Although attempts have been made to prevent rainwater permeation and leachate generation, trash scattering and scattering by harmful birds, leakage of odors, generation of pests, etc., waste is brought in every morning. Before starting the work, there was a drawback that much time and labor had to be spent on the work of collecting the resin sheet placed on the waste.
[0006]
    In order to eliminate such harmful effects, a non-woven fabric sheet disclosed in Japanese Utility Model Publication No. 7-21793 has been devised that has biodegradability and can be buried as it is even after it has been installed in a garbage disposal site. In addition, it contains a bulking material / setting material shown in the invention of JP-A-8-505600, a water-soluble polymer and water, and can be sprayed to give a strong and flexible water-repellent coating layer after spraying. A composition and a method for forming a foam protective coating layer for outdoor use have been developed. However, none of them is excellent in economic efficiency because all of the materials for forming the coating layer must be newly purchased. The problem of increasing the amount of waste at the waste disposal site remains unresolved.
[0007]
    In view of the actual situation of the already proposed treatment method as described above, the present invention reduces the accumulation of waste as much as possible, accumulates the waste in a limited volume of the disposal site, and collects the waste at a high density. As a result of deciding whether it is possible to realize a treatment method that is also useful for environmental conservation in and around it, the results of the rapid start of its development and research, and repeated trial and error over many years and numerous trial manufactures and experiments This time, we have finally succeeded in realizing a novel waste landfill treatment method and a waste coating layer having a novel structure used therefor. In the following, together with some embodiments representing the present invention, The configuration will be described in detail.
[0008]

The waste landfill treatment method is characterized by forming a coating layer of the same cement solution and repeating the landfill treatment so that a predetermined time elapses sequentially.
[0009]
    In this landfill disposal method consisting of this basic structure, the waste dumped in the waste disposal site is filled with a bulldozer, a tractor excavator, or other appropriate means so that it is as flat as possible. By crushing waste plastic into granular aggregate,This granulated aggregateA cement solution mixed with the waste plastic 1 at a weight ratio of cement 1 to 3, a hardening accelerator 0.5 to 0.1, a water retention agent 0.01 to 0.1, and water 0.5 to 1.5. , Sprayed almost uniformly on the filled waste material to a thickness of about 5 mm, sprayed to form a continuous and sealed coating layer, and then discarded again on the coating layer after a predetermined time It includes a waste landfill treatment method in which a landfill process in which a covering layer of a similar cement solution is formed after dumping and filling a material and a predetermined time elapses is sequentially repeated.
[0010]
    Similarly, after the waste dumped in the waste disposal site is filled with a bulldozer, tractor excavator, or other appropriate means to make it as flat as possible, the waste plastic is pulverized into fine particles. And then mixed with an appropriate amount of surfactant to synthesize resin emulsionAnd emulsifiedCement solution mixed with waste plastic 1 at a weight ratio of cement 1 to 3, curing accelerator 0.5 to 0.1, water retention agent 0.01 to 0.1 and water 0.5 to 1.5, A substantially uniform spray layer is formed by spraying and spraying on the filled waste to a thickness of about 5 mm, and a continuous and sealed coating layer is formed. A waste landfill treatment method is also included, in which a landfill process in which a coating layer of the same cement solution is formed after a dumping and filling process and a predetermined time elapses is sequentially repeated.
[0011]
    And if you show them as more concrete,After the waste dumped in the waste disposal site is filled with a bulldozer, a tractor excavator, or other appropriate means so as to be as flat as possible, cement 1-3 is applied to the waste plastic 1 pulverized into a granular form. A cement solution mixed in a weight ratio of Manol quick setting agent (trade name) 0.5 to 0.1, Metrolose (trade name) 0.01 to 0.1 and water 0.5 to 1.5.

After a predetermined time has passed, the waste is dumped again. Then, a waste landfill treatment method having a structure in which a covering layer of the same cement solution is formed after the filling treatment, and the landfill treatment for allowing a predetermined time to elapse is sequentially repeated.
[0012]
    Similarly, after the waste dumped at the waste disposal site is filled with a construction machine such as a bulldozer or a tractor excavator or other appropriate means so as to be as flat as possible, the waste plastic is pulverized to form a granular aggregate. And cement 1 to 3, manol quick setting agent (trade name) 0.5 to 0.1, metrolose (trade name) 0.01 to 0.1 A cement solution mixed in a weight ratio of 0.5 to 1.5 water is sprayed almost uniformly on the filled waste so as to have a thickness of about 5 mm, and sprayed to spread continuously and sealed. A layer is formed, and after a predetermined time has passed, waste is again dumped and filled, and then a similar cement solution coating layer is formed, and the landfill process is repeated for a predetermined time. The It can be said that the waste landfill processing method to memorial service.
[0013]
    In addition, the waste dumped in the waste disposal site is filled into a flat shape as much as possible by using a construction machine such as a bulldozer or a tractor excavator, etc. Mixing with an appropriate amount of surfactant to make a synthetic resin emulsion, the resulting waste plastic 1 is made of cement 1-3, manol quick-setting agent (trade name) 0.5-0.1, Metrose (trade name) ) A cement solution mixed at a weight ratio of 0.01 to 0.1 and water 0.5 to 1.5 is sprayed and spread almost uniformly on the filled waste so as to have a thickness of about 5 mm. Then, a continuous and hermetic coating layer is formed. After a predetermined time has elapsed, the waste is again dumped and filled, and then a similar cement solution coating layer is formed. It can be said that waste landfill processing method having the configuration as repeated sequentially landfill which is adapted to the elapsed time.
[0014]
    Further, according to the present invention, waste plastic 1 that has been dumped into a waste disposal site is pressure-treated so as to be as flat as possible by using a construction machine such as a bulldozer or a tractor excavator or other appropriate means, and then pulverized into a granular form. , A cement kneaded material obtained by mixing in a weight ratio of cement 1 to 3 in advance, and a manol quick-setting agent (trade name) of 0.5 to 0.1 with respect to the waste plastic 1; 01-0.1 Metrose (trade name) and 0.5-1.5 water solution are not mixed and sprayed separately to the same location, and the cement is placed on the filled waste The kneading material and the aqueous solution are sprayed so as to be mixed with each other, and are dispersed almost uniformly to a thickness of about 5 mm to form a coating layer of a continuous and sealed cement solution. Up again Dumping wastes, to form a coating layer by the same cement solution was Hama圧 treated waste landfill method comprising the configuration as repeated sequentially landfill processing so as to lapse of a predetermined time periodIs included.
[0015]
    FurthermoreAfter the waste dumped in the waste disposal site is pressure-treated by a construction machine such as a bulldozer or a tractor excavator or other appropriate means so as to be as flat as possible, the waste plastic 1 crushed into a granular form is cemented in advance. A cement kneaded material obtained by mixing at a weight ratio of ˜3 is a manol quick-setting agent (trade name) in a proportion of 0.5 to 0.1 with respect to the waste plastic 1 at the moment of spraying, 0.01˜ 0.1 Metroise (trade name), 0.5 to 1.5 water is added to form a cement solution, and sprayed almost uniformly on the filled waste to a thickness of about 5 mm, After spraying to form a continuous and hermetic coating layer, waste is again dumped and filled on the coating layer after a predetermined time, and then a similar cement solution coating layer is formed for a predetermined time. Landfill to let it pass Waste landfill processing method of construction which is adapted sequentially repeated physicalAlso included.
[0016]
    The filling process functions to increase the density of waste stored in the limited landfill facility and to make the upper part of the accumulated waste as flat as possible, and is successively carried into the waste disposal site. Compress incoming waste with construction machines such as bulldozers and tractor excavators and other appropriate means to eliminate irregularities, and reduce the required amount of cement solution to be sprayed on the waste. The aesthetics should be improved and the next landfill workability should be improved.
[0017]
    Waste plastic increases the strength of the coating layer as an aggregate of the cement solution, stops the development of cracks in the coating layer, or mixes with an appropriate amount of surfactant to form a synthetic resin emulsion to dry the coating. It serves to accelerate or smooth the surface of the coating layer,For waste plastic pulverized into powder,Grain with appropriate particle size within the range that is optimal for aggregates for concreteThingsOr by mixing with an appropriate amount of a surfactant to smoothen the surface of the coating layer and pulverize it into fine powders or fine particles to the extent that a property that improves drying and speeds up is obtained.Contains the best ones in itIt is possible to mix these waste plastics with different particle sizes in an appropriate proportion in the cement solution, and to combine the properties as an aggregate and the properties as a synthetic resin emulsion. Waste plastic materials that are less likely to elute and do not require sewage pollution measures or leachate measures at the time of final disposal, and are disposed of in a stable disposal site where soil is buried and buried in an underground digging hole. It is desirable to recycle.
[0018]
    Cement is mixed with an appropriate amount of water to form a cement paste, which functions to form a coating layer continuously and in a sealed manner with adhesive strength, and forms a film by adhering aggregates made of waste plastic. Or a cement solution with a synthetic resin emulsion obtained by mixing fine plastic particles with an appropriate amount of surfactant should form a film. Portland cement is generally used for construction in Japan. And other mixed cements can be used, and various admixtures and admixtures can be used as appropriate. Specific gravity, fineness, setting, stability, strength It can be said that it is desirable to use a material that has a performance sufficient to withstand the construction of ordinary buildings.
[0019]
    The hardening accelerator functions to strengthen the adhesive strength of the cement solution and solidify the coating layer so that it forms a relatively flexible sheet at an early stage after spraying. It must be hardened into a film at an early stage,Like the manol quick setting agent (trade name) taken up in the examples described laterIt is desirable to use a quick-setting agent or a fast-strengthening agent, and a material that does not cause cracks or pinholes in the coating layer even when rapidly cured should be selected.
[0020]
    The water retention agent retains moisture in the cement solution and hardens rapidly, preventing cracks and cracks, peeling from the waste, etc., ensuring stable adhesion and fixing, and rebounding and scattering during spraying operations. Which serves to preventFor example, from those represented by Metroles (trade name) as a water retention agent as in the examples described below,In addition to being able to replace the separation reducing agent, thickener, retarder and the like, a mixture of these admixtures in an appropriate ratio can also be used.
[0021]
    The water gives the cement solution a predetermined viscosity and prevents the cement itself from reacting to the mixed cement so that it can be prevented from splashing back or splashing around when sprayed onto the waste. It has the function of hardening and should not contain harmful amounts of substances that affect the quality of concrete, such as oil, acid, salt, etc., and can contain rainwater, river water, lake water, groundwater, drinking water, etc. It is desirable to use it.
[0022]
    The cement solution performs a function of forming a coating layer that is covered with a continuous and sealed sheet by being sprayed on the accumulated waste having an irregular shape. Cement, waste plastics, hardening accelerators, water retention agents, water mixing agents, etc. In addition to being able to be sprayed as a mixture, cement kneading material mixed with cement and waste plastics, water and hardening accelerators, water retention agents The coating layer can be formed so as to be mixed when sprayed on the waste, and the film is formed by the construction machine such as a concrete pump car or a concrete sprayer or other appropriate means. It is possible to form a film with a predetermined thickness on top. In addition, a coloring agent may be added as appropriate so that the coating layer is colored so as to improve the appearance of the disposal site.
[0023]
    The cement kneading material is a cement solution that exhibits adhesive strength when sprayed on and supplied with water together with water, and functions to enable the formation of a coating layer with a predetermined thickness on the waste. And an appropriate amount of waste plastic aggregate mixed in a dry state. At the same time as spraying, a hardening accelerator, water retention agent, water, etc. are mixed to create a cement solution instantly. It is also possible to form a film by simultaneously spraying a mixture of an appropriate weight proportion of waste plastic and an appropriate amount of a surfactant that have been pulverized in advance into fine particles with respect to water.
[0024]

    In relation to the above-mentioned waste landfill treatment method, the present invention also includes a waste film layer used in the waste landfill treatment method, and the gist of the configuration is basically as follows.
    That is, with respect to the powdered waste plastic 1, the weight ratios of cement 1 to 3, curing accelerator 0.5 to 0.1, water retention agent 0.01 to 0.1 and water 0.5 to 1.5 The mixed cement solution was thrown into a waste disposal site, and sprayed almost uniformly onto the appropriately packed waste so as to have a thickness of around 5 mm to form a continuous and sealed film. It is a waste film layer used for a waste landfill disposal method comprising a structure.
[0025]
    If the waste coating layer included in the present invention is shown in a more specific configuration, cement 1 to 3 and a manol quick-setting agent (trade name) 0.5 for the waste plastic 1 aggregated in a granular form. ~ 0.1, Metrose (trade name) 0.01-0.1 and water mixed in a weight ratio of 0.5-1.5, dumped cement solution to a waste disposal site, and appropriately filled waste It can be said that it is a waste film layer having a gist of a constitution in which a film is formed in a continuous and hermetically sealed state by spraying and spraying substantially uniformly so as to have a thickness of about 5 mm on the object.
[0026]
    Similarly, a synthetic resin emulsion can be prepared by mixing fine plastic waste plastic with an appropriate amount of surfactant.And emulsifiedWeight of cement 1-3 with respect to waste plastic 1, manol quick setting agent (trade name) 0.5-0.1, metrolose (trade name) 0.01-0.1 and water 0.5-1.5 The cement solution mixed at a rate is dumped in a waste disposal site, and sprayed and sprayed almost uniformly onto the appropriately filled waste so as to have a thickness of around 5 mm to form a continuous and sealed film. It can also be said that it is a waste film layer having the following structure.
[0027]
    The waste coating layer of the present invention is a mixture of a plastic resin emulsion obtained by mixing a granular plastic waste plastic or fine powdered waste plastic with a suitable amount of surfactant as a powdered waste plastic. And mixed with the waste plastic 1 at a weight ratio of cements 1 to 3, curing accelerator 0.5 to 0.1, water retention agent 0.01 to 0.1, and water 0.5 to 0.1. The cement solution is thrown into a waste disposal site, and sprayed and sprayed almost uniformly onto the appropriately filled waste so as to have a thickness of around 5 mm, and formed into a continuous and sealed film. It is possible, and the thickness of the coating layer is affected by the uneven shape etc. of the upper part of the waste, so some change is inevitable, but it does not cause cracks or peeling carelessly due to wind or wild bird mischief Can ensure continuity and sealing The thickness and should be one formed to ensure the viscosity.
    In the following, the structure will be described in detail together with some examples representing the present invention.
[0028]
[Example 1]
    In order to prevent groundwater contamination, a rubber sheet approximately 1.5mm thick is laid over the entire bottom and sides of the treatment space, and leachate and rainwater are collected and discharged after being properly treated at a purification facility. When one of the typical waste landfill treatment methods included in the present invention is carried out at a managed disposal site, it is transported one after another by a garbage truck or a transport vehicle that transports industrial waste. Move the waste coming from the rear side of the final disposal site sequentially with a construction machine such as a bulldozer or a tractor excavator, or a dedicated machine for moving and filling garbage, and then step on the heavy equipment. Compress and pack as flat as possible, after the day's dumping work for the day is completed, or for a section where dumping work at the disposal site will be suspended for a while. Te, to form a waste coating layer by the following procedure.
[0029]
    After cleaning and rinsing waste plastics such as synthetic resin molded products such as ABS resin, PP resin, polycarbonate resin and foamed plastic, which have been collected by removing foreign substances in advance and using appropriate detergents, the diameter of 1 to A cement solution is produced by crushing into about 3 mm granules and drying appropriately, or by adhering to the granular plastic without drying and mixing the water content included in the water / cement ratio described below In contrast to waste plastic 1 that has been processed into granules and can be used as an aggregate, Portland cement 2, 0.75 hardener accelerator (trade name) as a curing accelerator, and Metroze (product) as a water retention agent Name) 0.05, and the water, lake water, swamp water, groundwater or stored rainwater pumped up near the disposal site is homogeneous at a weight ratio of 1 Then, the mixture is supplied to a concrete pump truck and sprayed in a sprayed or sprinkled form from the back on the collected and flatly packed waste, and the thickness is about 5 mm on the waste. Then, it is retracted while forming a continuous and hermetic waste coating layer, covering all the target waste with a homogeneous waste coating layer, and waiting for drying for several hours.
[0030]
    When the next day or the next dumping is performed, the heavy work for moving and filling the dust enters the well-dried waste coating layer, and the newly introduced waste is sequentially moved to the back side. After the loading operation is completed, the same cement, waste plastic, admixture, and water are mixed and sprayed at the same ratio, and the thickness is 5 mm above the waste. The front and back waste coating layers are continuously formed in a sealed state and dried, and such operations are repeated until the managed disposal site is full.
[0031]
    In addition, the cement solution is washed and rinsed with a detergent, and a synthetic resin emulsion is prepared by mixing an appropriate amount of a surfactant with waste plastic that has been pulverized to form finer particles than cement. Thickness is obtained by spraying the waste plastic 1 on the waste with a homogeneous mixture of manol quick-setting agent (trade name) 0.5, Metrolose (trade name) 0.01, and water in a weight ratio of 0.5. A waste coating layer of about 5 mm can be formed continuously and in a sealed state.
[0032]
[Example 2]
    As another embodiment of the waste landfill treatment method included in the present invention, the bottom and side surfaces of the disposal site are surrounded by concrete having a thickness of 10 cm or more, and a roof is attached to block the ingress of water. An example of the final disposal of industrial waste in a closed disposal site that must be structured to prevent contamination can be given as an example, and it will be implemented as follows.
[0033]
    In other words, waste such as incineration ash, sludge, slag, and dust that has been brought into the intercepted disposal site is collected from the back using bulldozers, other appropriate construction machines, or dedicated machines for moving and filling garbage. After pressurizing to make it flat, waste plastics such as synthetic resin molded products and foamed plastics that have been classified and collected in advance are washed and rinsed with an appropriate detergent, and then made into fine particles. Crushing and drying in such a manner, cement is mixed with the atomized waste plastic 1 at a weight ratio of 2 to make a cement kneaded material. A manol quick-setting agent (trade name) as a curing accelerator with a weight ratio of 75, a Metrose (trade name) as a water retention agent with a weight ratio of 0.05, and 1 for the waste plastic 1 Weight percent Prepare the become water supplies respectively to the concrete spraying machine.
[0034]
    Waste at the back of the disposal site is adjusted and controlled so that cement kneading material, manol quick-setting agent, metroise and water supplied separately to the concrete sprayer are sprayed at the same location of the accumulated waste. The cement kneading material, manol quick setting agent, metroise and water jetted from the nozzle of the concrete sprayer are mixed with each other at the moment when they collide on the waste. A solution is formed, and this cement solution forms a coating layer having a thickness of about 5 mm on the entire upper surface of the target waste, and its outer peripheral edge adheres to the concrete wall on the side wall of the disposal site. And a waste film layer is formed after drying.
[0035]
    Next, when dumping, after moving and accumulating waste on a well-dried waste coating layer as described above, cement kneading material, manol quick setting agent, metroise and water are added by a concrete sprayer. Spray and spray to form a uniform waste coating layer with a thickness of around 5 mm on the upper side of the waste so that it is continuous and sealed, and then dry, and repeat the same operation until the blockage disposal site is full It is what you want to go.
[0036]
[Action]
    The waste landfill processing method of the present invention having the above-described configuration is a bone obtained by crushing waste plastic on waste that is accumulated in a management-type disposal site and compressed and flattened. A waste solution layer having a thickness of about 5 mm is formed so as to be continuous and sealed by spraying or spraying a cement solution containing the material into a uniform layer shape, or sprinkling into a sprinkled shape. The adhesive strength of the cement and the weight of the cement solution keep the waste coating layer on the waste, and the waste covered with the waste coating layer is sealed by the waste coating layer continuous over the covered area. Light weight waste that is scattered in the surrounding area by the wind, such as paper, vinyl film, and powder particles without waiting for the cement solution to dry, was suppressed by its adhesive strength and weight Together becomes state, and that the coating layer be continuous obscures to prevent the blowing of direct wind.
[0037]
    Since the cement solution has sufficient adhesive strength, it is possible to ensure the continuity and sealability of the coating layer even in the rain spraying operation, and the manol rapid as a hardening accelerator contained in the cement solution. Binders harden the surface layer of the coating layer rapidly to prevent unevenness and loss of the coating layer due to dripping, and Metroze as a water retention agent delays the evaporation of moisture in the cement solution for a long time. In addition to maintaining the flexibility of the coating layer, it prevents the occurrence of cracks, pinholes, and the like so that it is sealed, and prevents rain and accompanying flowing water from entering the waste. Moreover, since the weight of the cement contained in the waste coating layer suppresses the waste on the lower side, the waste once packed before spraying is further pressure-set and settled almost uniformly over the entire surface. .
[0038]
    In addition, a synthetic resin emulsion can be made by mixing an appropriate amount of a surfactant with waste plastic that has been pulverized so that it is finer and finer than cement. Accelerates drying and improves the appearance by smoothing the surface of the waste coating layer, and the fine powdered waste plastic stops the development of cracks that occur in the drying cement, thereby preventing the generation of cracks and pinholes. It will prevent you.
[0039]
    After the waste dumped in the closed-type disposal site is filled as flat as possible, the waste plastic is pulverized into fine particles and dried using a concrete sprayer. As a cement kneading material mixed at a ratio of 0.1%, a manol quick-setting agent (trade name) as a curing accelerator with a ratio of 0.75 to the waste plastic 1, and a water retention agent with a ratio of 0.05 If you spray all of the water at a ratio of 1 to the waste plastic 1 all at once, the cement kneading material, manol quick setting agent, metroise and water will be stagnant at the moment of reaching the waste. A cement solution coating layer is formed as one unit, and the cement kneading material, admixture and water bounce back and rise during the spraying process, deteriorating workability. With the one that prevents, becomes to prevent ash by the force of spraying, sludge, slag, waste such as dust is that soar becomes splash.
[0040]
    The waste coating layer with a thickness of around 5mm formed on the entire surface of the waste prevents the seepage of rainwater and running water, and the paper, film or powdery waste is blown by the strong wind and scattered in the surrounding area. , Prevents leakage of strange odors, prevents the scattering of waste by wild birds and wild mice, and improves the appearance, eliminates the need to cover and collect sheet materials, and is discarded every day or every predetermined period While implementing the landfill treatment method to cover waste and cover the waste coating layer, the waste is dumped so that multiple layers are sandwiched between multiple waste coating layers. As a result, it is possible to maintain an isolated state for each layer, and to minimize the damage even if leachate occurs, and to promote the high density integration of the waste disposal site. .
[0041]
【effect】
    As described above, according to the waste landfill treatment method of the present invention, the coating layer can be formed by spraying the cement solution after the end of the disposal operation, so that the sheet material covering operation and the recovery operation are unnecessary, It is possible to continue the dumping work over the previously formed coating layer, and it is possible to improve the work efficiency dramatically and to cover the waste dumped at the disposal site to cover paper, powder, etc. Is prevented from splashing in the surrounding area, preventing the generation of leachate and leaking of bad odors, suppressing the scattering of waste by wild animals and the generation of pests, and bringing them into the disposal site and collecting them The waste material is compressed with a construction machine such as a bulldozer or a tractor excavator or other appropriate means, and is pressed into a flat shape and sprayed with a cement solution to form a waste coating layer of about 5 mm. Since the process of forming is carried out, it is possible to achieve the integration and densification of the accumulated matter confined under the coating layer by the filling operation and the sedimentation action due to the weight of the continuous coating layer on the dumped material. Thus, in the current situation where it is difficult to secure a new disposal site, it is possible to obtain an excellent feature that it is possible to prolong the life of the disposal site by effectively utilizing the volume of the currently available disposal site.
[0042]
    In addition, according to the waste coating layer of the present invention, since all of the components are selected within the range of five stable items, no recovery is required, and the waste is dumped and accumulated over the coating layer. It is possible to form a coating layer so as to form a layer and repeat it multiple times, and mix the cement with the pulverized waste plastic as the main component of the cement solution As a matter of fact, by recycling waste plastics, it is possible to achieve both reduction of waste and cost reduction, and by mixing appropriate amounts of curing accelerator and water retention agent, It is possible to ensure the continuity of the coating layer and form a coating layer with excellent hermeticity, and to improve the external appearance of the entire disposal site by eliminating the exposure of waste. The ones that can be effective.
[0043]
    In particular, the waste landfill treatment method described in the examples and the waste coating layer used for the waste landfill use a cement solution that is recycled from aggregated waste plastic granulated by pulverization treatment in addition to the features described above. This reduces the use of cement and admixtures and improves the durability of the coating layer.Furthermore, an appropriate amount of surfactant is mixed with the waste plastic that has been pulverized into fine particles to form a synthetic resin emulsion. By blending with cement, the surface of the coating layer can be smoothed to improve the appearance, and drying can be promoted to eliminate problems such as dripping and runoff after spraying. It is possible to form a waste coating layer with a uniform film thickness, and to reduce the man-hours of spraying work and improve work efficiency dramatically. Thereby achieving the great feature that kill.
[0044]
    Further, cement solution mixed with waste plastic 1 at a weight ratio of cement 1 to 3, effect promoter 0.5 to 0.1, water retention agent 0.01 to 0.1, and water 0.5 to 1.5. Is sprayed almost uniformly onto the waste that remains to some extent even if it is filled to make it as flat as possible, and sprayed to spread the coating layer with a thickness of about 5 mm continuously and hermetically. The composition ratio is optimal for forming, ensuring sufficient strength to withstand natural environments such as wind, snow, and snow. It is possible to achieve a special effect of significantly improving workability.
[0045]
    As described above, the waste landfill treatment method of the present invention and the waste coating layer used for the waste landfill layer can achieve the intended purpose uniformly by the novel configuration, and the waste plastic is recycled. In addition to greatly contributing to the reduction of waste, it uses only materials selected from the so-called five stable items, minimizing adverse effects on the natural environment, making construction easy and economical. In addition, the volume of the disposal site can be used efficiently by dramatically increasing the density and density of the waste, and the scaffolding is solidified by the construction of the laminated structure. Since the safety and work efficiency of the move can be greatly improved, it is possible to reliably reduce costs and work man-hours, and to efficiently use the final disposal site, as well as hygiene management and environmental conservation. For Are highly evaluated by industrial waste disposal contractors and government officials, and related industries and organizations, and are expected to be widely used and spread. .
