Problems solved by technology

The food waste filtrate is made into compound microbial fertilizer through microbial fermentation, especially emphasizing the role of microorganisms. However, because the food filtrate has a high content of COD, salt ions, ammonia nitrogen, and E. coli and other pathogenic and harmful microorganisms, it has not yet been used. There are specific microbial agents used in the degradation and transformation of kitchen filtrate

Abstract

The invention relates to the field of microbial preparations and particularly discloses a compound microorganism bacterium agent and a preparation method and application thereof. The compound microorganism bacterium agent comprises lactic acid enterococcus faecalis, bacillus subtilis and bacillus megaterium, wherein the total viable count of the agent is not less than 3.5*108 cfu / mL. The compound microorganism bacterium agent is composed of reasonable strains according to composition characteristics of kitchen filtrate, can quickly degrade harmful substances in the kitchen filtrate, has a remarkable effect on degrading COD, BOD, ammonia nitrogen and the like in the kitchen filtrate and can effectively degrade organic matter to greatly relieve odor of the kitchen filtrate; the processed kitchen filtrate can also be used as a raw material of compound microorganism water-soluble fertilizer, so that the utilization rate of energy sources is increased, and environmental pollution caused by direct discharge of the kitchen filtrate is reduced.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a composite microbial preparation and its preparation method and application. Background technique [0002] With the development of the city, various wastes and garbage also emerge as the times require, among which kitchen waste is an important part. The current general method of dealing with food waste is to separate the food waste into solid and liquid, and process the solid part into feed, fertilizer, etc., while the liquid part is mostly discharged directly or enters the sewage treatment system. Studies have found that the direct discharge of a large amount of organic matter in the kitchen filtrate will pollute the groundwater, and the generated methane and strong odor will seriously affect people's life and health. Research has found that kitchen filtrate is rich in organic matter and nitrogen sources, and the reuse of these substances is not only of great significance...
