Preparation method of biological full-degradation kitchen waste FDM microbial inoculum

Abstract

The invention relates to a preparation method of a biological full-degradation kitchen garbage FDM microbial inoculum. The preparation method comprises the following steps: step 1, raw material preparation: culturing bacillus cereus fermentation liquor, aspergillus oryzae fermentation liquor, micromonospora purpurea fermentation liquor, candida krusei fermentation liquor and acetobacter aceti fermentation liquor, wherein the effective viable count in each single component in the microbial inoculum is high, the kitchen waste can be completely and quickly degraded only by a small amount of the microbial inoculum, the degradation rate is up to 96%, the amount of wastewater generated after the kitchen waste is fully degraded by the FDM microbial inoculum is small, granular precipitates are few, and up-to-standard discharge can be realized through a simple water treatment process.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation in bioengineering, in particular to a method for preparing and applying an FDM bacterial agent for fully biodegrading kitchen waste from kitchen waste. Background technique [0002] Food waste refers to the food waste and residues generated in the process of food processing and dining in residents' families, catering industry and canteens of enterprises and institutions. It is one of the main components of urban domestic waste. According to the average daily output of 1 ton of kitchen waste per 10,000 people in my country's cities, the annual production of kitchen waste in my country has actually exceeded 50 million tons. Therefore, how to deal with these massive food wastes is an urgent and complicated problem. [0003] The main treatment method of kitchen waste is landfill or incineration together with domestic waste. Landfill disposal of kitchen waste is likely to cause land po...

AI Technical Summary

Problems solved by technology

Although the resource-based food waste equipment without auxiliary materials has realized the transformation of most of the food waste into organic fertilizers, the composition of fertilizers is relatively complex, may contain harmful substances, and has not achieved efficient reduction, especially in cities The organic fertilizer produced by it is difficult to deal with

[0005] Therefore, organic fertilizer type food waste treatment equipment has not completely solved the problem of food waste treatment in general, and there is an urgent need to develop bacterial agents that can fully degrade food waste
