Abstract
The invention relates to urban and rural waste treatment and utilization, in particular to an urban and rural waste treatment method. The method comprises the following steps: sorting and classifying wastes; smashing organic wastes and then adding a microbial starter, and adding straw or sawdust to regulate water content; after stirring, carrying out anaerobic fermentation in a fermentation tank, and using the anaerobic-fermented product as feed for fly larvae and earthworm breeding; collecting residues of fly larvae and earthworm breeding, and composting and fermenting to prepare organic fertilizers. Combustible wastes are incinerated through an incinerator to supply heat for the fermentation tank, fly larvae and earthworm breeding rooms and composting fermentation equipment. The method carries out resource utilization, innocent treatment and reduction landfill for the wastes and fundamentally controls the secondary pollution caused by the direct landfill, incineration and composting of wastes.
Description
Technical field
The present invention relates to waste, particularly offal treatment and utilization.
Background technology
Town and country waste and domestic refuse, human and animal excreta, fairground rubbish, the set of the various rubbish such as varieties of food items, non-staple food processing factory's tankage, have landfill, burning, compost etc. to its treatment process now, these methods respectively have drawback.One is landfill, though a large amount of waste of dissolving, easily causes the secondary pollution of long-term groundwater resource, also produces the obnoxious flavoures such as biogas, and will consume a large amount of soils, two is burning methods, the incineration plant construction of pure waste and productive expense are quite expensive, great economic burden can be produced to local government, pure waste contains a large amount of inorganics and hydrate simultaneously, the objectionable impuritiess such as Dioxins will be produced when incineration temperature does not reach and requires, its toxicity is very large, causes secondary pollutant to environment, three is compost, by the organism in waste through pre-treatment, Primary Fermentation, secondary fermentation, aftertreatment, the operation such as deodorization and storage, organic matter is become fertilizer, though solve the outlet of rubbish, the object of renewable resources can be reached again, but consumer garbage compost amount is large, overall nutrient content is low, production site needs life-time service, groundwater quality is equally easily caused to degenerate, the same waste water producing environmental pollution during compost fermentation, waste gas, so, the scale of compost also cannot be done greatly, and about the amount that can be used for compost in waste total amount only accounts for half, and second half still needs landfill or burning.Along with the increase of population, the raising of living standards of the people, urban and rural domestic refuse output in rising tendency year by year, in the face of these are more and more and don't irrespective waste, will be those skilled in the art's problem demanding prompt solution.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned refuse processing method, a kind of town and country refuse processing method is provided, waste is got utilization, harmless treatment, minimizing landfill, has fundamentally administered the direct landfill of waste, secondary pollution that burning, compost cause.
Object of the present invention is achieved through the following technical solutions:
A kind of town and country refuse processing method, comprises the following steps:
(1) waste go-on-go is sorted out: waste is carried out go-on-go classification by recovering discarded material, combustible waste material, organic waste, other waste, be wherein that flammable and organic waste is classified as combustible waste material, other described wastes are waste remaining after town and country waste removes recovering discarded material, combustible waste material, organic waste;
(2) smokeless waste incinerator and fermentor tank, fly maggot vermiculture room, compost fermentation equipment connection are formed heating system;
(3) combustible waste material process: combustible waste material adopts smokeless waste incinerator to burn;
(4) organic waste treatment: obtain organic crushed products after being pulverized by organic waste, add microbial starter culture, adds stalk or wooden chaff regulates water content, carries out anaerobically fermenting after stirring in fermentor tank;
(5) fly maggot vermiculture: the tunning obtained by step (4) is cultivated as feed in fly maggot vermiculture room;
(6) resistates after cultivation fly maggot earthworm and microbial starter culture are placed in compost fermentation equipment and make organic chemical fertilizer through compost fermentation, after drying-granulating, finished product fertilizer can be obtained.
The equipment that waste go-on-go described in step (1) is sorted out is go-on-go rotating disk.
Step (2), the incinerator described in (3) are normal pressure hot blast, hot water dual-purpose incinerator.
Step (4) and the microbial starter culture described in (6) are EM bacterial classification stoste, and EM bacterial classification stoste contains photosynthetic bacterium group, lactobacillus, yeast flora, actinomycete group, thread flora.
The microbial starter culture quality that every kilogram of organic waste described in step (4) adds is 1g ~ 2g, and water content is 40% ~ 65%.
Anaerobically fermenting temperature described in step (4) is 40 DEG C ~ 65 DEG C, and fermentation time is 15 ~ 40 days.
Fly maggot breeding temperature described in step (5) is 25 DEG C ~ 30 DEG C, and vermiculture temperature is 20 DEG C ~ 25 DEG C.
The microbial starter culture quality that every kilogram of resistates described in step (6) adds is 1g ~ 1.5g, and compost fermentation temperature 40 DEG C ~ 65 DEG C, fermentation time is 7 ~ 14 days.
Present method regulates the water content in waste by blending straw, wooden chaff dry-matter, make not have sewage to produce in production process, really reach harmless treatment.Be converted into the feed of fly maggot earthworm after straw, wooden chaff and organic matter fermentation, finally become fertilizer, fundamentally solve the various secondary pollutions that organism produces in landfill.
The inventive method has following beneficial effect:
One, be used for cultivating fly maggot earthworm by after fermentation organic in waste, then its resistates is made fertilizer, realize utilization of waste as resource, overall utilization reaches more than 80%.
Two, the efficient garbage incinerator incineration of combustible waste selected, both combustible waste material can be disposed, can can ensure anaerobically fermenting to fermentor tank, fly maggot vermiculture room, the heat supply of compost fermentation equipment again, low temperature season normally cultivates, thus make waste be able to continuous process.Selected incinerator is normal pressure hot blast, hot water two-purpose stove, and system does not exist potential safety hazard.The flue gas of combustiblematerials discharged in burning reaches discharging standards, and wherein dioxin gas is far below discharging standards.
Three, organic matter is mixed microorganism species and carries out anaerobically fermenting by present method, does not produce obnoxious flavour and waste water, work circumstances safe in fermenting process.
Four, after organic waste being converted into feed and fertilizer, the amount of landfill of waste is greatly reduced, and reduction rate can reach more than 80%, decreases secondary wastewater, exhaust emission that landfill produces, add the working life of landfill yard, thus decrease appropriation of land.
Five, by not mercurous, plumbous in the organic waste that obtains after artificial separation, cadmium, etc. heavy metal, the fly maggot earthworm cultivated and the fertilizer of making do not have heavy metal substance to remain.
