Problems solved by technology

[0004] There are reports on the use of earthworms to treat urban waste and a small amount of human and livestock manure from farmers, but for farms with an annual output of tens of thousands of tons, the combination of biogas bacteria and earthworms to efficiently treat manure through the biological chain has not been reported.

Embodiment Construction

[0016] The conversion of the present invention can be divided into the first layer conversion of livestock and poultry manure into biogas and biogas residue and the second layer conversion of biogas residue into feeding soil for breeding earthworms.

[0017] Among them, the first layer of conversion: livestock and poultry manure is converted into biogas and biogas residue.

[0018] Firstly, make the raw materials for fermentation: mix 70kg of livestock and poultry manure, 20kg of crushed straw, sorghum husk and other agricultural and sideline products and 10kg of water evenly. After 3 hours, stack retting for 5 days to obtain the fermentation raw material; then when the temperature in the fermentation raw material stack reaches 50°C, add 0.5kg of urea, 5kg of plant ash and 10kg of water to 1000kg of fermentation raw material and stir evenly to make the carbon-nitrogen ratio 30 : 1, the pH value is 7.5, and then poured into the biogas digester; then add water at 30°C in the bio...

Abstract

The invention relates to a high-efficiency biological-chain treatment and multi-level conversion method for livestock and poultry manure, in particular to a biological-chain treatment and product conversion method for the manure of an intensive farm. Aiming at providing a high-efficiency biological-chain treatment and multi-level conversion method for livestock and poultry manure, the invention adopts the following proposals: the first-level conversion: converting the livestock and poultry manure into firedamp and residue; the second-level conversion: converting the residue into feed soil to breed earthworms, a. preparing the feed soil, and b. breeding the earthworms. The invention is widely used for solving the manure pollution problems of intensive scale large and medium-sized farms.

Description

technical field [0001] The invention relates to an efficient treatment and multi-level conversion method of livestock and poultry feces bio-chain, specifically a method for intensive farm feces bio-chain treatment and product transformation. Background technique [0002] In recent years, with the rapid growth of my country's economy and the improvement of the living standards of urban and rural residents, my country's poultry breeding industry has developed towards scale and intensification. There are nearly 15,000 farms with more than 100 cattle and more than 100,000 chickens. These farms discharge more than 1.7 billion tons of livestock and poultry manure every year, and the discharge of organic matter is about 7 million tons, which is more than 1 million higher than the discharge of organic matter in industrial wastewater nationwide. tons; if flushing water is included, it is estimated that the total amount of sewage discharged annually exceeds 20 billion tons, which is equ...
