Abstract

The invention discloses a composite bacterial agent for efficiently degrading kitchen garbage, and a preparation method and application thereof. The efficiently degrading kitchen garbage, and preparation method and application thereof consists of a starch-degrading strain, an oil-degrading strain, a protein-degrading strain, a cellulose-degrading strain and a vector; and the preparation method comprises the following steps of: performing enrichment culture on each single strain, screening, and preparing the vector; and mixing a high-quality composite bacterial agent with the vector. The synergism of various microorganisms in the natural world is fully utilized, a microorganism-based control method is established, and the composite bacterial agent is utilized for coupled fermentation of the kitchen garbage to accelerate the biogas fermentation progress, improve the traditional fermentation process and improve the biogas yield.

Description

technical field [0001] The invention relates to a microbial bacterial agent and a preparation method and application of the microbial bacterial agent. Background technique [0002] With the development of my country's economy and society and the continuous improvement of people's living standards, the amount of food waste generated has increased rapidly. The National Environmental Bulletin shows that in 2001, the amount of food waste removed in my country was 40.411 million to 53.882 million tons, and food waste accounted for about 30% to 40% of urban domestic waste. Kitchen waste is mainly food processing waste (kitchen waste) and food residue (swill) produced in catering operations and residents’ lives. Its components are mainly water, sugar, protein, fat, salt, etc., and are rich in nutrients. Due to its The output is large and scattered, and it is easy to be corrupted and smelly, polluting urban roads, air, and surrounding water systems, leading to the breeding of insec...
