Problems solved by technology

In the traditional treatment of livestock and poultry manure as organic fertilizer, due to the low price of agricultural organic fertilizer, most breeding enterprises cannot bear the cost of collection and transportation, or due to low profits, enterprises are not motivated enough to process it. Randomly piled up livestock and poultry manure, polluting the environment

Embodiment 1

[0037] Mix 75g of sawdust into 1000g of chicken manure, dilute 0.5g of decomposing bacteria 500 times, add evenly, adjust the water content to 50-60%, cover with plastic cloth, and ferment for 24 hours. After fermentation, add water to make the water content reach 70%, then spread the material on the breeding box with a thickness of 8cm, pour 25-35g of black soldier fly larvae above the third age, at a temperature of 25-35°C, 75%- Cultivate under 80% air humidity conditions for 8 days, then add 70g of dry rice bran, reduce the water content to about 35%, and screen out 110-130g of black soldier fly larvae and 480-520g of waste. After processing the waste, adjust the water content to 60%, cover it with plastic cloth, and after 48 hours of decomposition, spread the fermentation material with a thickness of 35cm. When the temperature drops to the same temperature as the environment, put 2-3-year-old white star Cultivate 50-75g of beetle larvae at a temperature of 26°C-35°C for 20...

Embodiment 2

[0039] Mix 600g of chicken manure, 200g of pig manure, and 200g of cow manure, add 60g of sawdust, dilute 0.5g of decomposing bacteria 500 times, add evenly, adjust the water content to 50-60%, cover with plastic cloth, and ferment for 12 hours . After fermentation, add water to make the water content reach 70%, then spread the material on the breeding box with a thickness of 10cm, pour 25-35g of black soldier fly larvae above the third age, at a temperature of 25-35°C, 75%-80 Cultivate for 7 days under the air humidity condition of 100%, then add 70g of dry rice bran, reduce the water content to about 35%, and screen out 105-125g of black soldier fly larvae and 480-520g of waste. After processing the waste, adjust the water content to 60%, cover it with plastic cloth, and after 48 hours of decomposition, spread the fermentation material with a thickness of 35cm. When the temperature drops to the same temperature as the environment, put 2-3-year-old white star Cultivate 50-75...

Abstract

The invention discloses a method for completely converting poultry excrement step by step through hermetia illucens and potosia brevitarsis. A small amount of saw powder is added to the poultry excrement to be mixed, the water content of the poultry excrement is adjusted, microbial inoculums are added for fermentation for 12-24 hours, hermetia illucens larvae are introduced, and conversion treatment is conducted. Commodity larvae are separated from materials, larva bodies are high-protein insects and can be used as feed or deeply processed, after waste is fermented, potosia brevitarsis larvae are introduced for further conversion treatment, and potosia brevitarsis larva bodies and particle frass are obtained. The method is high in treatment and conversion capacity and high in efficiency and benefit, the treatment process is low in energy consumption, secondary high-efficiency utilization of the poultry excrement is achieved, two types of produced larvae have high economic value, particle organic fertilizer can be directly used for agricultural production, a great significance is achieved in solving ecological environment pollution and raising incomes of farmers, and thus the method has wide market prospects.

Description

technical field [0001] The invention relates to a treatment method for livestock and poultry manure, in particular to a method for completely converting livestock and poultry manure step by step using black soldier flies and white star beetles Background technique [0002] In recent years, the aquaculture industry has developed rapidly, and the aquaculture industry has made important contributions to satisfying consumer demand, driving employment in rural areas and increasing farmers' income. However, with the development of the breeding industry, more and more manure is produced. For example, in 2011, the production of livestock and poultry manure in my country was 2.121 billion tons. The resulting manure disposal problem has attracted more and more attention from the society. In the traditional treatment of livestock and poultry manure as organic fertilizer, due to the low price of agricultural organic fertilizer, most breeding enterprises cannot bear the cost of collectio...
