Abstract
The invention provides a curing agent special for curing and stabilization of poisonous and harmful solid waste. With a bicomponent structure, the curing agent is composed of a liquid and powder together. The poisonous and harmful solid waste refers to ion state heavy metal-containing soil particles, construction waste and sludge. The curing agent can stimulate related elements in the solid waste to undergo crosslinking reaction to form a chain structure so as to achieve the purposes of curing and stabilization of poisonous and harmful solid waste. In the early stage of curing reaction, the transfer ability of poisonous substances in the hazardous waste is limited, at the middle stage of curing reaction, the poisonousness of the poisonous substances is reduced and the poisonous substances can be polymerized into large clusters of particles to be adsorbed, and at the end of curing reaction, poisonous and harmful substances do not seep.
Description
Technical field
The present invention relates to field of Environment Protection, particularly relate to a kind of curing agent of administering for poisonous and harmful solid waste solidification and stabilization.
Background technology
For the processing of poisonous and harmful solid waste, landfill is that one is the easiest, the most direct processing method.Take sanitary landfills can effectively reduce the pollution to underground water, surface water, soil and air.Each city can be looked for a remote place on the outskirts of a town, for solid danger waste landfill site.On request, landfill yard must do antiseep processing, prevents that the solid danger poisonous and harmful substance in useless is penetrated into underground, contaminated soil and water body.In fact because antiseepage and the sealing ability of landfill yard are limited, there is the seepage of the useless leachate of solid danger, and the flying away of the useless dust of solid danger, make the liquid and the powder that contain a large amount of heavy metals and harmful substance enter ecological circulation, health is caused to serious threat.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of special, for the curing medicament of poisonous and harmful solid waste solidification and stabilization.Described poisonous and harmful solid waste refers to the soil particle, building waste, the mud that contain ionic state heavy metal.
Poisonous and harmful solid waste solidification and stabilization curing agent of the present invention is bicomponent structure, be made up of A agent and B agent, it comprises polymine, sodium metnylene bis-naphthalene sulfonate, polyethylene glycol dispersant, sodium metasilicate, Ludox, calcium sulfate, calcium hydroxide, flyash, attapulgite, water.By mass parts, by Ludox 10%-40%, A agent is made in water 60%-90% mixing barrelling; By calcium sulfate 5%-30%, calcium hydroxide 5%-40%, flyash 10%-40%, attapulgite 10%-40%, polyethylene glycol dispersant 0.1%-3% mix after in grinding to 350 order below 200 DEG C, after grinding, powder temperature is cooled to 40 DEG C to add below polymine 0.1%-5% again, and sodium metnylene bis-naphthalene sulfonate 0.01%-0.5%, sodium metasilicate 3%-10% make B agent.
The advantage of curing agent of the present invention and good effect are first to slow down the migration of heavy metal harmful substance in solid waste, reduce poisonous and harmful solid waste in solidification and stabilization processing procedure to atmosphere, soil, the pollution of water, then heavy metal ion is carried out to chelating absorption, further reduce toxicity and the transfer ability of heavy metal ion, a large amount of reactive groups generation chemical reaction that interacts in last and solid waste, cause that chemical bond and molecule connection are cross-linked into three-dimensional-structure, trend chemistry is stable simultaneously, original molecular structure and intermolecular framework change gradually, this change makes molecular structure become tough and tensile, the three-dimensional polymer being cross-linked is insoluble, not molten, heavy metal ion in it is sealed completely, reach the object of poisonous and harmful solid waste solidification and stabilization.
Detailed description of the invention
Below in conjunction with instantiation, poisonous and harmful solid waste solidification and stabilization of the present invention is described in further detail with curing agent.
Embodiment 1
It is the heavy metal cadmium that contains of 100 cubic metres to volume, zinc, plumbous, arsenic, the soil of nickel and content superstate standard of soil environment quality (GB15618-1995) grade III Standard, be cured stabilization processes, calculating pending soil quality according to the density 1.8t/m3 of general soil is 180 tons, spray 5.4 tons of A agent according to soil moisture content situation according to 3% of soil quality, without puddling, A agent has been sprayed after 10 hours and has been dispensed B agent, B agent use amount is 10.8 tons according to 6% of soil quality, use digging machine, loading machine or other large-scale mixing plants dispense while puddle, after puddling evenly, do suitably and roll.
Solidification and stabilization soil after treatment is without doing special maintenance, only need to carry out anti-rain protection, the content of heavy metal in the leachate that after 7 days, sample analysis soil is measured by the lixiviate mode of regulation in solid waste " Leaching leaching method sulfuric acid nitrate method " (HJ/T299-2007), after processing, the leaching value of cadmium is less than 0.01mg/L, plumbous leaching value is less than 0.05mg/L, the leaching value of arsenic is less than 0.05mg/L, all lower than the " requirement of III class water concentration limit value in groundwater quality standard 》 ﹙ GB/T14848-93 ﹚.
Claims (3)
1. a poisonous and harmful solid waste solidification and stabilization curing agent, it is characterized in that for bicomponent structure, be made up of A agent and B agent, it comprises polymine, sodium metnylene bis-naphthalene sulfonate, polyethylene glycol dispersant, sodium metasilicate, Ludox, calcium sulfate, calcium hydroxide, flyash, attapulgite, water.
2. poisonous and harmful solid waste solidification and stabilization curing agent according to claim 1, is characterized in that by mass parts, by Ludox 10%-40%, A agent is made in water 60%-90% mixing barrelling; By calcium sulfate 5%-30%, calcium hydroxide 5%-40%, flyash 10%-40%, attapulgite 10%-40%, polyethylene glycol dispersant 0.1%-3% mix after in grinding to 350 order below 200 DEG C, after grinding, powder temperature is cooled to 40 DEG C to add below polymine 0.1%-5% again, and sodium metnylene bis-naphthalene sulfonate 0.01%-0.5%, sodium metasilicate 3%-10% make B agent.
3. poisonous and harmful solid waste solidification and stabilization curing agent according to claim 2, is characterized in that A agent is liquor, and B agent is pulvis.
