Description

The sullage solidifying method of sludge curing agent and use sludge curing agent
Technical field
The present invention relates to the sullage solidifying method of a kind of sludge curing agent and use sludge curing agent.
Background technology
Produce a large amount of mud in the training of channel, the lake dredging up process,, often need great amount of manpower and resource for handling these mud; In the prior art, the method for handling these mud mainly contains two kinds: the one, find special-purpose landfill place, and mud is stacked; And then the filling of blowing sand, yet the drawback of this kind method is: need a large amount of special landfill places; The while labor intensive, transportation cost is high; Another kind of treatment process then is in mud, to add solidifying agent to solidify; CN98113594.3 discloses a kind of soil-solidified-agent, and the slag of its use 78-85% or slag compsn, the alkali-activator of 10-25%, the tensio-active agent of 0.01-0.15% carry out soil treating, yet; Owing to lack solidifying agent such as cement in this formula constituent; Its solidification effect, for the water ratio soil with high, effect can be had a greatly reduced quality.In addition, prior art stresses that the adding solidifying agent promotes the mechanical strength such as the unconfined compression strength of mud or soil, yet the slightly acidic of mud can cause certain harm to environment, and it does not cause the attention that people are enough.
Summary of the invention
First technical problem to be solved by this invention provides a kind of sludge curing agent, is used for curing sludge efficiently.
Second technical problem to be solved by this invention provides a kind of sullage solidifying method that uses sludge curing agent, is used for curing sludge efficiently.
In order to solve first technical problem, the technical scheme that the present invention taked is:
This sludge curing agent is processed by following method:
First-selection will comprise that expansible black lead, cement, flyash, carbon black, silica flour, china clay and seven kinds of compositions of unslaked lime mix, and be not less than under the expansible black lead expansible temperature, expansible black lead expanded, and stir the mixture, and obtain work in-process;
In work in-process, add and comprise that two kinds of compositions of swollen resin and water glass stir thorough mixing together, process solidifying agent.
Preferably: the mass fraction of said expansible black lead, cement, flyash, carbon black, silica flour, china clay and six kinds of compositions of unslaked lime is: expansible black lead 20 ~ 40, cement 10 ~ 30,10 ~ 20 parts in flyash; Carbon black 0.1 ~ 5; Silica flour 1 ~ 20, china clay 5 ~ 30, unslaked lime 5 ~ 10.
Expansible black lead is after expansion, and tens of times to hundreds of times of volumetric expansions form the loose porous bulk materials that is similar to floss.Expansible black lead on the market has turgidity 60,100,200,250,300ml/g or the like different extent specification.Form numerous loose thick holes in the expansible black lead after the expansion, cotton-shaped graphite floss can form the monomer of independently accompanying after being stirred cut-out, all is attached with other mixture on these monomers.Expansible black lead expansible expansion temperature has in it adulterated composition and structure decide.Expansible black lead mainly is the effect of playing powder carrier, the mixture thickness more that after mixing moisture content, can seem.And in the dark hole of hiding expansible black lead such as the part of absorbent material such as cement, flyash, unslaked lime etc.; Form supercrescence; For moisture content in the mud; Except some water itself can be inflated graphite (address after expansible black lead expands) the absorption, also can slowly stretch into hole and some parasitic material generation chemical reactions wherein, further absorb moisture content.Such structure forms two kinds of simultaneous modes of a physics suction and chemistry suction.In the physics water absorption course, the moisture content in the mud expands in its inner pore in the parasitic particle along the expanded graphite surface arrangement, and parasitic particle and water react, and moisture content is combined fully, as becoming calcium hydroxide after the unslaked lime suction; Become lime carbonate after the cement suction.The mode of moisture content in such absorption mud can more fully and uniform absorb moisture content in the mud, can not form the local absorption deficiency, remaining moisture content, and local solidification agent effect is insufficient, and the phenomenon of luming takes place.Expansible black lead has good thermal conductivity, and when using the sun to quicken sludge dewatering, it can be transmitted to various piece in the mud faster with heat, quicken combining of moisture content in solidifying agent and the mud, and the moisture content heat absorption is evaporated in the mud.Because expanded graphite proportion is little, use very that the expanded graphite of light weight just can reach the good heat transfer effect, if adopt the Graphite Powder 99 conduction, then need expend too much.In the mud, can constitute mobile moisture content and be easy to be inflated graphite and the absorption of endoparasitism material thereof, the typing of mud primary solidification is very obvious.Remaining moisture content in the mud slowly absorbs through other composition, and the mud stripping and slicing of preliminary sizing and solidifying is placed under the sun is exposed to the sun, and accelerates sludge solidification efficient.While mud moulding, that have certain degree of hardness helps further being used also convenient, like the material as brick.
The effect of cement is the gumminess that increases mud, mud is bonded together, and makes mud hardening, so its ratio can be bigger in solidifying agent.
Flyash comprises a lot of compact grains, and its particle diameter is very little, and hydration can take place, and thinks except that this also to have the vesicular structure material.Flyash includes some MOXs and can react with water, and therefore, it can absorb water.Flyash can well be filled in the expanded graphite mesoporosity, owing to also have vesicular structure in it, it can be used as more short grained secondary, parasitic carrier.Flyash exists physics suction and chemistry suction dual mode when in the hole of expanded graphite, absorbing the moisture content of moisture content.Because flyash is used for colonizing in expanded graphite, therefore, its consumption is unsuitable many, should be less than the consumption of expanded graphite.
Carbon black pellet is little, and it also has good water-absorbent.Carbon black mainly is to be used for remedying the deficiency that thermal conductivity descends, carbon property weakens that there is hole in expanded graphite as auxiliary material.It can well be distributed in the hole of expanded graphite, increases its carbon density.In addition, carbon black can increase the black level of mud, makes it absorb sunlight more easily, accelerates to solidify, and particularly summer, sooty colouring function just contribution is remarkable.Can find out that carbon black plays regulating effect here, but still can not ignore the performance that it has suction.
The silica flour composition is mainly silicon dioxide granule, and its particle diameter is very little, and mean particle size reaches nano level.Silica flour mainly is to cooperate cement to use, and it can improve the performance of cement, and therefore, its consumption according to cement is adjusted design.
China clay, its modest viscosity is used for filling the hole of expanded graphite and is blended in mud, improves the intensity of expanded graphite and mud, and in addition, china clay has good thermal conductivity, uses in mud in a large number, can quicken the transmission of solar heat.It helps the heat conduction between the post-rift expanded graphite segment body.Do not needing under the heat conduction solidified situation, china clay can use the gypsum of equivalent to substitute.Gypsum has the effect of strengthening mud hardness.Because cement is material necessary in the solidifying agent of the present invention, the retardant that china clay and gypsum all can be used as cement uses.But because china clay is the raw material of pottery, it has the brilliant characteristic that becomes of special high temperature.In mud, add china clay,, after curing, can its stripping and slicing be recycled, promptly be fired into the mud earthenware brick, perhaps make various mud ceramic artworks etc. then for such mud.
Unslaked lime, it mainly is to be used for suction, and produces a large amount of heats, makes mud be in the higher environment of temperature higher chemical reaction velocity and the effect that helps improving between the particulate of temperature, and the evaporation that also can quicken moisture content.The acidity that it also is used to regulate mud makes environment be alkalescence.When quicklime particles is present in the hole of expanded graphite; It can absorb the moisture content of being come by the expanded graphite surface diffusion; And reaction produces heat with it; Moisture content around the heat energy evaporation, this process can be quickened the velocity of diffusion of moisture content in the hole of expanded graphite, helps other absorbent material and absorbs moisture content.
Swollen resin is used for absorbing mud nonabsorbable excessive water for other composition of solidifying agent.Because expansible black lead mainly is the parasitic carrier that is used for as other absorbent material, its water-retaining capacity is limited.For the different mud of water cut, and not exclusively be suitable for.In order to adapt to the mud of wideer water content ranges, add a certain amount of swollen resin as the additional of expansible black lead seemed particularly necessary.But swollen resin suction back is soft loose, and it can weaken the hardness of mud, promptly offsets the hardness influence that expanded graphite produces mud.In order to strengthen the hardness of mud, therefore, add water glass and regulate as the hardness of mud.Water glass can absorb the water of a part simultaneously.
Preferably: said swollen resin is ZX-I or SEPIGEL 305.
Preferably: the mass fraction of said swollen resin and water glass is: swollen resin 1 ~ 3, water glass 1 ~ 10.It is big that the amount ratio swollen resin of general water glass is wanted.Swollen resin each particle of back that expands all becomes an independently suction group, and it is that suction is just expanded, and is different with expansible black lead, and is not easy after the suction to dewater, and soaking effect is good.But because it becomes particulate state, do not have association between the group after the suction, therefore, can cause mud to become loose, easy of crack becomes piece or powder behind the sludge solidification.
Preferably: said expansible black lead the expansion temperature scope be 200 ~ 400 degrees centigrade.Also there are 400 degree and above in the temperature of expansible black lead, for example 500 degree.
Preferably: in said solidifying agent, also be mixed with sea salt, the mass fraction of sea salt is 0.1 ~ 3.Also have a large amount of suction salt in the sea salt, help absorbing the water in the mud, in addition, sea salt dehydration back forms does not have the fixedly polycrystalline of shape, and dirt settling is hardened, and promptly increases sludge solidification and moulding, avoids loose.The salt composition is complicated in the sea salt, and crystal is constantly according to environment generation repetition crystallization in dehydration and water absorption course repeatedly for it, and xln changes along with the body of dirt settling, this structure can strengthen mud with the solidifying agent mixed dehydration after the effect that hardens.
Preferably: in the mixture of said seven kinds of compositions, also be added with saltcake, perhaps in two kinds of compositions of follow-up interpolation, add SODIUM SULPHATE ANHYDROUS 99PCT again; The mass fraction of the SODIUM SULPHATE ANHYDROUS 99PCT in the solidifying agent is 0.1 ~ 3.Saltcake is used for suction, and it can promptly keep the balance of suction dehydration in lower temperature (thirties degrees centigrade) dehydration down under the temperature in the mud whipping process, and the balance of this suction dehydration makes saltcake become a kind of catalyzer, with the effect of water molecules transfer.Saltcake has good water-absorbent, and it can replace sea salt, as artificial additive.If it cooperates sea salt to use, can remedy the inefficient deficiency of sea salt effect.
In order to solve above-mentioned second technical problem, the present invention proposes a kind of sullage solidifying method that uses sludge curing agent, may further comprise the steps:
1) mud is sieved;
2) mud and the sludge curing agent after will sieving mixes.This sludge curing agent is processed by following method: first-selection will comprise that expansible black lead, cement, flyash, carbon black, silica flour, china clay and seven kinds of compositions of unslaked lime mix; Be not less than under the expansible black lead expansible temperature; Expansible black lead is expanded, and stir the mixture, obtain work in-process; In work in-process, add and comprise that two kinds of compositions of swollen resin and water glass stir thorough mixing together, process solidifying agent.
Wherein, sludge curing agent can also comprise following preferred version:
Optimal way: the mass fraction of said expansible black lead, cement, flyash, carbon black, silica flour, china clay and six kinds of compositions of unslaked lime is: expansible black lead 20 ~ 40, cement 10 ~ 30, flyash 10 ~ 20; Carbon black 0.1 ~ 5; Silica flour 1 ~ 20, china clay 5 ~ 30, unslaked lime 5 ~ 10.
Optimal way: said swollen resin is ZX-I or SEPIGEL 305.
Optimal way: the mass fraction of said swollen resin and water glass is: swollen resin 1 ~ 3, water glass 1 ~ 10.
Optimal way: the expansion temperature scope of said expansible black lead is 200 ~ 400 degrees centigrade.
Optimal way: in said solidifying agent, also be mixed with sea salt, the mass fraction of sea salt is 0.1 ~ 3.
Optimal way: in the mixture of said seven kinds of compositions, also be added with saltcake, perhaps in two kinds of compositions of follow-up interpolation, add SODIUM SULPHATE ANHYDROUS 99PCT again; The mass fraction of the SODIUM SULPHATE ANHYDROUS 99PCT in the solidifying agent is 0.1 ~ 3.
The sullage solidifying method that uses sludge curing agent is further preferably: the mass ratio of described mud and solidifying agent is: cement 9 ~ 11 is than last solidifying agent 0.5 ~ 2.Hardener dose can increase cost too much, can weaken effect very little.One preferably embodiment be 10 parts for cement, solidifying agent is 1 part.
Preferably: the mixing temperature of mud and solidifying agent is 10 ~ 90 degrees centigrade, puts into irradiation completion of cure under the sunshine after mixing is accomplished.Solarization can reduce cost under the sun, and under sweltering heat in the summer situation, efficient is higher, and can utilize the advantage of carbon black heat absorption.10 degrees centigrade is under the environment in winter, and solidifying agent possesses an active essential condition, if be lower than 10 degree, and the swollen resin expansion effect variation in the solidifying agent, more under the low temperature, water can freeze.90 degrees centigrade is issuable temperature after the sun in summer direct projection ground area heat.The selection of temperature will consider that the composition in the solidifying agent is active.Saltcake for example, thirties degree just are in the rapid adjustment equilibrium stage of suction, dehydration, seventies degree, the gypsum that unslaked lime suction back produces begins again to dewater.Water molecules can take place and exchange in salt in the suction dehydration, and crystal form can constantly change, and then the moulding of hardening of effect mud.Because much salt present white, it can be reflective, hinders and absorb sunshine, therefore, suitably increases the absorption that carbon black helps to increase sunshine, improves the mud temperature inside, and acceleration moisture content is absorbed and evaporates.
The invention has the beneficial effects as follows: sludge curing agent of the present invention is joined in the mud, can make the mud water ratio low, solidification effect is good, and efficient is high, and can solve the slightly acidic problem of mud.
