Problems solved by technology

[0002] At present, the implementation of domestic waste classification is an important issue facing our country. A large amount of domestic kitchen waste obtained after the classification of domestic waste needs to be further efficiently transformed. The composting method currently used is the most commonly used method to deal with this type of waste. This treatment method is used every Only about 0.3 tons of organic fertilizer can be obtained per ton, the waste water generated during the fermentation process penetrates into the soil, the exhaust gas pollutes the atmosphere, and the utilization rate of raw materials is very low

Embodiment 1

[0016] 1 ton of domestic kitchen waste is fermented under the condition of isolation from the air. After fermentation, the residue obtained after crushing and suction filtration to remove water is mixed with 30%-50% of dry pig manure to enhance the gas permeability of the waste residue, and put it into the fly In the maggot culture dish, spread it into a thickness of 5 to 10 cm, add fly eggs, keep the room temperature at 30-35°C, and keep the humidity at 50-70%. After 4-5 days, the fly eggs hatch into fly maggots and grow into adult maggots and adult flies. Adult maggots and flies are sterilized to make high-protein feed. After being separated into maggots, the remaining residues are reused until only fibrous substances remain in the residues. The remaining fibrous residues are collected and put into the earthworm breeding base. Transform it into high-quality organic fertilizer vermicompost, and produce a large number of earthworms by-product.

Embodiment 2

[0019] 1 ton of domestic kitchen waste is fermented under the condition of isolation from the air. After fermentation, the residue obtained after crushing and suction filtration to remove water is mixed with 30%-50% peanut straw powder, put into fly maggot petri dishes, and spread out into 5 to 10 cm thick, add fly eggs, keep room temperature 30-35 ℃, humidity 50-70%, 4-5 days fly eggs hatch into fly maggots and grow into adult maggots, adult maggots and flies are sterilized to make high Protein feed, after being separated into maggots, the remaining residues are reused until only fibrous substances remain in the residues, and the remaining fibrous residues are collected and put into the earthworm breeding base, and finally all the residues are transformed into high-quality organic fertilizer vermicompost, and as a side effect Produces large numbers of earthworms.

[0020] The method produces 0.4 tons of sterile fly maggots, 50 kilograms of earthworms, 20 kilograms of fly powd...

Abstract

The invention discloses a method for breeding fly larvae and earthworms by kitchen garbage. The method is characterized in that the kitchen garbage is treated by the following steps: fermenting the kitchen garbage in a vacuum condition; regulating pH to 5-8; crushing, filtering and dewatering the kitchen garbage to obtain residual slag; adding 30%-50% of dried pig manure, dried cow manure, peanut straw powder, corn straw powder, other straw powder or mixture; putting the mixture to a fly larvae culture dish, paving the mixture in 5-10 thickness; adding fly eggs; maintaining the room temperature to be 30-35 DEG C and humidity to be 50-70% so that the fly eggs become fly larvae and then become maggots; after separating maggots, repeatedly performing the above steps by the residual slag till only fibrous material is remained in the residual slag; and adding the residual slag to the earthworm breeding base to breed earthworms. The method overcomes the problem that the utilization efficiency of the kitchen garbage after being treated by composting method is low, eliminates soil pollution, reduces air pollution and achieves recycling of the garbage.

Description

technical field [0001] The invention relates to a method for treating domestic kitchen waste, in particular to a method for raising fly maggots and earthworms with domestic kitchen waste. Background technique [0002] At present, the implementation of domestic waste classification is an important issue facing our country. A large amount of domestic kitchen waste obtained after the classification of domestic waste needs to be further efficiently transformed. The composting method currently used is the most commonly used method to deal with this type of waste. This treatment method is used every Only about 0.3 tons of organic fertilizer can be obtained per ton, and the waste water generated during the fermentation process penetrates into the soil, the exhaust gas pollutes the atmosphere, and the utilization rate of raw materials is very low. Contents of the invention [0003] In view of the above-mentioned shortcomings, the present invention adopts a recycling method of comp...
