Compound bacterial agent and method for treating feces sewage of pig farm

Abstract

The invention relates to a compound bacterial agent and method for treating feces sewage of a pig farm. The efficient compound microbial bacterial agent obtained through a large amount of compounding operation can efficiently achieve harmless treatment on the feces sewage with low consumption, and the problems existing in the process of treating the feces sewage of the pig farm are solved. In the meanwhile, bran is utilized for curing the compound microbial bacterial agent, so that the influence of impact of external factors on microbes is lowered, the activity is high, the density is high, and certain stability is maintained. The compound bacterial agent and the method are used for treatment of the feces sewage of the pig farm, have the advantages of being easy to operate and convenient to manage, and can economically and efficiently treat organic pollutants in the feces sewage of the pig farm.

Description

technical field [0001] The invention relates to a composite bacterial agent and a method for treating pig farm feces and sewage. Background technique [0002] Livestock waste from livestock farms (mainly including sewage, dung and odorous gases discharged from livestock and poultry farms) has become a major environmental problem faced by rural areas and agriculture. Human health will have direct or indirect impacts. my country is a big country in the pig industry in the world. With the development of the pig industry, the pig breeding mode has gradually transformed into an intensive breeding stage, and the environmental pollution caused by a large number of concentrated excrement and sewage discharges has become more and more serious. Facing the problem of pig farm sewage treatment with high organic matter and high ammonia nitrogen characteristics, the theory and experience accumulation of current domestic treatment methods are still insufficient, and the design of treatmen...

AI Technical Summary

Problems solved by technology

However, these traditional pig farm manure treatment processes, such as the treated manure and sewage, are difficult to find sufficient and effective consumption land under the current rural land system; the land lease fee is expensive, and it is difficult to adopt the artificial wetland process that requires a large land area; High project cost, high operating cost, professional management is required, and the traditional activated sludge treatment method has extremely poor treatment effect in winter, etc., all of which restrict the promotion and application of the existing sewage treatment technology in large-scale pig farms

[0004] Single-species microbial preparations have poor adaptability to the environment and are unstable

At the same time, due to the fluidity of pig farm sewage and the surrounding unfavorable environmental conditions, it is easy to cause the bacteria to lack carriers in the fluid water body, easy to lose, and the density of bacteria to decrease, which limits the microbial purification effect.
