Abstract
The invention relates to a method for cultivating matrix nutrient soil by means of household waste incineration fly ash, and belongs to the technical field of household waste treatment. The method comprises the steps that cornstalks, wood bits, rice bran, blue-green algae and other nutrient media are added to culture water hyacinth with enriched heavy metal together with a municipal solid waste incineration fly ash elution solution, excessive water is removed through enriched eluted municipal solid waste incineration fly ash and some heavy metals in urban sludge, on the basis of feeding of earthworms, the mixture is mixed with soil, decomposition transformation is performed through the sand pocket mechanical friction action and biochemical action inside intestinal tracts, and heavy metals are enriched; meanwhile, due to the method for producing matrix nutrient soil by mixing produced wormcast and remaining matrixes, existing household waste incineration fly ash is well treated, and the household waste incineration fly ash can be effectively recycled.
Description
Technical field
The present invention relates to a kind of method of utilization domestic garbage incineration flyash culture medium Nutrition Soil, belongs at house refuse
Reason technical field.
Background technology
Domestic waste produce in burning process containing sour gas, gaseous state heavy metal and dioxin it is poisonous,
The flue gas of harmful substance, is cleaning discharge flue gas, it is necessary to spray into acid gas absorbent, activated carbon by flue gas purification system and inhale
Attached dose etc., poisonous and harmful substances, reacted acid gas absorbent, acticarbon are removed by physical-chemical reaction
Trapped together by sack cleaner in company with adsorbed heavy metal, dioxins materials, form incineration of refuse flyash（Referred to as fly
Ash）.Containing dioxin and the noxious substance that heavy metal etc. is difficult to natural degradation can be leached in flying dust, to surrounding and the mankind
Health has high risks.
Municipal sludge refers to produced aqueous solid precipitate in city domestic sewage, During Industrial Wastewater Treatment Process
Matter, with moisture content is high, volatile material and the characteristics of more ash, some municipal sludges also containing a large amount of pathogenic microorganisms and
The pathogen such as parasitic ovum and the heavy metal and toxic organic compound of some difficult degradations.
At present, the treatment approach of China's fly ash from burning city domestic garbage and municipal sludge mainly using sanitary landfills and is done
Change and burn, do not only take up a large amount of land resources, can also cause heavy metal pollution.Rubbish is the resource for having misplaced position, is slightly located
Manage, just reproducible utilization.Therefore, appropriate disposal technology is studied, is existing fly ash from burning city domestic garbage treatment technology face
The significant difficulty for facing and problem demanding prompt solution.
The content of the invention
The technical problem to be solved：Mainly adopt for the treatment approach of current fly ash from burning city domestic garbage
With sanitary landfills and anhydration and incineration, a large amount of land resources are not only taken up, can also cause the problem of heavy metal pollution, the present invention to provide
The nutrient matrixes such as a kind of addition corn straw, wood flour, Testa oryzae, cyanophyceae, cultivate with fly ash from burning city domestic garbage leacheate
A kind of Herba Eichhorniae of enriching heavy metal, and in its fly ash from burning city domestic garbage being enriched with after drip washing with municipal sludge
Part heavy metal, then remove after excessive moisture, is eaten by Lumbricuss, and and mixing with soil, gizzard mechanical friction effect and
Biological chemistry action in intestinal carries out decomposition and inversion, enriching heavy metal, while output wormcast and remaining substrate are mixed into
The method of Culture media, has dealt carefully with existing domestic garbage incineration flyash, and effectively realizes domestic garbage incineration flyash
Recycle.
Locate to solve above-mentioned technical problem, the technical solution used in the present invention is：
