Problems solved by technology

[0003] At present, a variety of food waste treatment technologies have been developed for food waste. However, the fermentation bacteria used in the existing technology are mostly EM complex bacteria. However, the fermentation time is long and the stench is easy to be generated in the process of using the above bacteria. Restricts the application of aerobic treatment technology for food waste

Abstract

The invention relates to kitchen garbage biological fermentation microbial inoculum. The kitchen garbage biological fermentation microbial inoculum consists of four or more of bacillus subtilis, bacillus licheniformis, cellulomonas flavigena, pseudomonas pesodoalcaligenes, rhodop seudanonas palustris, frankiaceae actinomycesbovis, debaryomyces hansenii, and candida tropicalis and is loaded to a carrier consisting of one or two of wheat bran, saw dust or straw, and is subjected to freeze drying to obtain the microbial inoculum; and the microbial inoculum is mixed with kitchen garbage, and a fermentation reaction is performed under 50-65 DEG C, so that the kitchen garbage can be reduced by 70% within 6-10 hours, and the content of generated organic matter exceeds 90%. The kitchen garbage biological fermentation microbial inoculum has the advantages that the technical method can efficiently reduce kitchen garbage, the treated substances can be used for soil modification, and the kitchen garbage biological fermentation microbial inoculum has remarkable economic, social and environmental benefits.

Description

technical field [0001] The invention relates to a microbial bacterial agent for treating kitchen garbage, in particular to a biological fermentation bacterial agent for kitchen garbage and its application. Background technique [0002] Food waste is the most important type of food waste, including food processing waste and food residues generated by families, schools, canteens and catering industries. Food waste is mainly composed of grease, water, fruit peels, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels and other substances. The output of food waste in my country is huge, with an annual output of more than 100 million tons, and it is showing a rapid upward trend. Because the water content in food waste is as high as 90%, and the salt content is relatively high. The current main treatment methods for food waste include incineration and landfill. Due to the high moisture content and low calorific value, the incineration process cons...
