Method for making compost from livestock and poultry manure

Abstract

The invention provides a method for making compost by using poultry night soil. The method comprises the following steps: blending fresh poultry night soil with a microbial agent according to a mass ratio of 1000:1, adding straw powder, carrying out pile turning mixing to obtain 1 part by mass of a compost body, and distributing 1 part by mass of the uniformly mixed compost body in a fermentation bed. The method for making compost by using poultry night soil allows decomposed compost intermediate products to be added to the fermentation bed in a circulating manner, so the compost rapid heating is promoted, the compost process is accelerated, the compost period is shortened, and the consumption amount of the microbial agent is reduced, thereby the production cost is reduced. The method has the advantages of short period, high yield, no pollution, no bacteria, ovum residue and the like, enables a fertilizer generated in the invention to have a high retention rate of nitrogen, phosphorus, potassium and other elements, processes high pollution wastes, creates new economic values, and has good economic and social benefits and very good demonstration and popularization values.

Description

technical field [0001] The invention relates to the technical field of compost production, in particular to a method for making compost from livestock and poultry manure. Background technique [0002] Since the reform and opening up, my country's livestock and poultry breeding industry has developed very rapidly. Many large and medium-sized intensive farms have been established in the suburbs, and the number of livestock and poultry has increased rapidly. standard of living. At the same time, the output of livestock and poultry manure is also increasing rapidly. Livestock and poultry manure contains a large amount of nitrogen, phosphorus, suspended solids, pathogenic bacteria and high concentrations of organic pollutants. cause serious harm to living things. In order to protect and optimize the natural ecological environment, control and eliminate the pollution of livestock and poultry manure to the environment, one of the important ways is to carry out harmless treatment a...

Problems solved by technology

For example, feces often contain harmful bacteria and insect eggs, which cannot be completely killed by a simple treatment process. Therefore, in developed countries such as Europe, America and Japan, livestock and poultry manure are basically no longer used as feed; All of them will produce secondary pollution and be seriously affected by the environment. In the environment where our country's current awareness of environmental protection is increasing, this kind of method of pollution control will be gradually eliminated; A large amount of water is wasted. On the other hand, the one-time investment of biogas projects is high, the daily operation and maintenance costs are high, the economic benefits are poor, and capital recovery is difficult. In northern areas, insulation measures must be taken in winter to maintain normal operation, and the amount of pollutants will increase, which is economically unfavorable. It is cost-effective and will increase the pollution of the farm itself, which largely limits the large-scale promotion of biogasification
