Abstract
The invention provides a composite biomass charcoal waste incineration fly ash treatment stabilizer which comprises a biological source stabilizer component, pyridine modified bentonite and a carrier matrix. When fly ash is treated by the novel stabilizer provided by the invention, stable and lasting chemical reaction can be produced, heavy metal and organic pollutants in the fly ash can be effectively fixed, the leaching toxicity can be reduced, the sanitary landfill standards can be met, and relatively high acidification-resistant performance can be realized; the dosage of the stabilizer is low, so that the consumption of a conventional stabilizer can be greatly reduced, the cost of fly ash treatment can be reduced, and the effective utilization rate of the fly ash can be increased; the stabilizer can treat a waste with another waste, and has remarkable economic, social and environmental benefits.
Description
Technical field
The invention belongs to incineration of refuse flyash and stablize processing technology field, be specifically related to the application utilizing composite biomass charcoal as a kind of eco-friendly fly-ash heavy metal fixative.

At the material that recuperation of heat utilizes system, flue gas purification system to collect after flying dust refers to waste incineration.The generation of flying dust with rubbish kind, burn condition, burn the type of furnace and flue gas treating process relevant, generally account for about the 3%-5% of waste incineration amount.In flying dust containing a large amount of lead, zinc, cadmium, mercury etc. heavy metal and its esters and multiple persistence organic pollutant, wherein bioxin mainly contains organic pollutants in flying dust.Dioxin be many chlorodiphenyls also-general designation to-bioxin (PCDDs) and polychlorinated dibenzo (PCDFs), the CONCENTRATION DISTRIBUTION of flying dust Zhong dioxin isomers has similar feature, and the content of high Lv Dai dioxin is apparently higher than low Lv Dai dioxin.Generally believe that waste incineration is one of main source of environment Zhong bioxin at present.Pollutant in above-mentioned flying dust, if not treated, can move after direct entered environment in the environment, not only can produce serious influence to environment, also can enter human body by food chain, threatens health.Flying ash is clearly classified as a class hazardous waste by " the Pollution in Municipal Solid Waste Incineration control criterion " of China, must carry out harmless treatment disposal.The annual municipal refuse output of current China is at about 1.8 hundred million tons, about 7% is burning disposal, and the generation of flying dust is by 3%, and annual flying dust generation is about 37.8 ten thousand tons, therefore need cheapness, efficiently technology to carry out process to flying dust to dispose, reduce its environmental risk.
Drip washing and immobilization are the two class main method processing pollutant in flying dust at present.Drip washing refers to and adopts water or solution washing flying dust, reduce pollutant load thus reduce its environmental risk, but due to flying dust be the product after high temperature incineration, metal occurrence patterns is complicated, therefore the simple aqueous solution is difficult to be washed out, and thus needs some chemical leaching drip washing.And after flying dust drip washing process, also can produce the problem of secondary pollution and water pollutions, the difficulty of thus flying dust drip washing process is comparatively large, cost is higher.Immobilization process, also referred to as stabilisation, is after being mixed with incineration of refuse flyash by immobilization medicament, utilizes the reaction of immobilization medicament and metal to generate mineral or insoluble substance, thus reduces the stripping of heavy metal and organic pollution.Existing immobilization medicament is divided into inorganic stabilizers and the large class of organic stabilizer two.Conventional medicament has gypsum, phosphate, bleaching powder, sulfide (sodium thiosulfate, sodium sulphate), macromolecule organic stabilizer, ferrite, clay mineral, N benzoyl N phenyl hydroxyamine etc.Compared with inorganic stabilizers, organic stabilizer has that added amount of chemical is few, increase-volume amount is little, the advantage of stable in properties, but also there is selling at exorbitant prices and cause using limited problem.Although therefore laboratory research shows the good fixing effect of organic fixative, not large-scale industrial production and the use because cost is high, and general all only effective for inorganic heavy metal, but for organic pollution as the fixed effect of bioxin is not good.
Therefore, although flying dust immobilization process is the flying dust processing mode of a kind of simple possible, non-secondary pollution, need many for pollutant type in flying dust, endanger large feature, exploitation wide spectrum, novel, cheap, efficient immobilization medicament.This is the key affecting the development of flying dust immobilization treatment technology at present and promote waste incineration development.But up to now, not yet while of discovery energy, the research of the incineration of refuse flyash fixative of immobilization organic pollution and various metals is reported, does not also find the application study of composite biomass charcoal in flying dust process process.
The invention provides one utilizes agricultural planting and livestock waste to produce a kind of composite biomass charcoal as incineration of refuse flyash process stabilizing agent, not only realize waste resource to utilize, can also the advantage of comprehensive inorganic stabilizing agent and organic stabilizer, have that consumption is few, effect is high, stable performance, with low cost, and the feature of heavy metal and organic pollution can be fixed simultaneously, and.
