Abstract

This invention discloses a method for treating urban domestic garbage. The method comprises: selecting recyclable urban domestic garbage, pulverizing the residual garbage, mixing with animal feces, fermenting in a methane pool, utilizing produced methane for heating or electricity generation, taking out the precipitate from the methane pool, mixing with grass fodder, composting for 20-30 days, and culturing earthworm. The method can effectively utilize urban domestic garbage. The method does not occupy soil, and does not cause pollution.

Description

Biochemical treatment method for household garbage

Technical field

The present invention relates to environmental technology field, relating in particular to the domestic rubbish disposal in the city is zero system schema and the biochemical technical field of utilizing method.

Background technology

All to produce a large amount of domestic refuses in each city, people are to the processing of rubbish now, adopt the method for piling up or burying mostly, not only take a large amount of land resourcess, make valuable soil become the rubbish massif, and, these rubbish produce a large amount of germs and virus, environment is polluted, all endangering human beings'health, have endless trouble all the time.

Summary of the invention

The objective of the invention is to invent a kind of treatment process of consumer waste innocent, neither land occupation does not pollute environment again.

Technical solution of the present invention is: after sorting out recyclable class material, will remain rubbish and pulverize, and sneak into animal excrement then, and place methane-generating pit to ferment; The biogas that produces is used for heating or generating; Throw out takes out in the methane-generating pit, and throw out and forage mixing stack retting after 20～30 days, are used for breeding earthworm.

It can be garbage treatment that zero systems technology scheme and biochemistry utilizes method that the present invention uses a whole set of, these world's public hazards of rubbish are carried out biochemical treatment to turn waste into wealth, this public hazards have been eradicated for the mankind are nonvolatil, and with the biologic chain biochemical method of science it has been become wealth, the also human cleaning ambient that promotes the well-being of mankind, clean room, fine, the healthy world.The present invention can realize neither land occupation, again the purpose that environment is not polluted.

Among the present invention, the residue rubbish after the pulverizing is 100: 30～45 with the mixed weight ratio of animal excrement.

Also plant can be sneaked in the residue rubbish after the pulverizing, the residue rubbish after the pulverizing is 100: 15～20 with the mixed weight ratio of plant.

During stack retting, throw out is 100: 15～25 with the mixed weight ratio of forage.

The present invention produces biogas with rubbish earlier, and the waste of biogas is made the breed material of earthworm, and be used for nutrition purposes, especially for feeding animals with earthworm now, forms an ecological chain.

After the earthworm oven dry, make powdery through pulverizing, be used for the feed ingredient raw material.Stretch on the further edge that is ecological chain.

Also can make the fertilizer of plant with after the oven dry of earthworm ight soil.

Embodiment

1, domestic refuse is focused on classification to be sorted on the cement court of building up in advance.

2, with artificial and the netted iron sieve of instrument rubbish is sorted classification, reclaim callable, and reject toxic substance.

3, expendable rubbish bits are sieved with netted iron sieve, the rubbish that particle is big is pulverized with pulverizer, using after pulverizing with the mixed stack up of the rubbish that sieved.

4, look pulverizing back rubbish and how much contain organism, can add an amount of again some pigs of admixture of plants such as some husks, leaf or broken grass, chicken, human faecal mass in right amount and mix to be transported to after mixing thoroughly and carry out fermentative processing in the methane-generating pit of building up in advance, several can be recycled the biogas pond.Residue rubbish after the pulverizing is 100: 30～45: 15～20 with the mixed weight ratio of animal excrement, plant.

5, the biogas that is produced is during the fermentation used mounted equipment in advance, carries out illuminating and heating, oven dry, for methane-generating pit self use in each greenhouse of native system, oven dry workshop.

6, treat that the rubbish fermentation in the methane-generating pit finishes, throw out at the bottom of the pond is taken out, throw out is mixed stack retting after 20～30 days with forage with weight ratio 100: 15～25, when wetness is suitable, it is transported to the substratum as breeding earthworm uses in the warmhouse booth of the breeding earthworm of building up in advance.

7, the earthworm seed of choosing is in advance put into substratum and culture, earthworm is a food with the rubbish that ferments, growth procreation therein.

8, treat that earthworm grows up to after, the rubbish put was in advance also eaten up by earthworm and was discharged as ight soil this moment, biochemistry has become the organic handle of high-quality has expected, can separate earthworm with its ight soil, can take trapping or other method to separate, then processing respectively.

9, the earthworm after will separating is put in the service sink of building up in advance and cleans, after the sterilization, can be used as fresh and alive feed and feed soft-shelled turtle, swamp eel, crab, Penaeus vannamei and chicken, redundance can be dried and is ground into powdery, alternative fish meal is made processing feed ingredient usefulness, also can be made into medicine and food.

10, the earthworm ight soil after will separating is suitably dried, metering, pack, and this be senior high-quality fertilizer, can be used for the melon and fruit in the warmhouse booth in the native system, vegetables use.But the native system warmhouse booth is owing to there is the biogas heating to make to guarantee off-season cultivation strawberry, cucumber, tomato etc.Out-of-season sale improves the economic benefit in the native system.Redundance can be used as the high-quality organic fertilizer and is sold to vegetable grower, tea grower and forest farm or peasant and makes fertilizer and use.

So far domestic waste is turned waste into wealth by native system technical scheme and biochemical treatment, is treated to zero, and these public hazards of rubbish have forever eradicated completely.

Claims

1, biochemical treatment method for household garbage, sort out recyclable class material after, it is characterized in that residue rubbish is pulverized, sneak into animal excrement then, place methane-generating pit to ferment; The biogas that produces is used for heating or generating; Throw out takes out in the methane-generating pit, and throw out and forage mixing stack retting after 20～30 days, are used for breeding earthworm.

2, according to the described biochemical treatment method for household garbage of claim 1, the residue rubbish after it is characterized in that pulverizing is 100: 30～45 with the mixed weight ratio of animal excrement.
