Kitchen waste composite microbial degradation agent as well as preparation method and application thereof

Abstract

The invention discloses a kitchen waste composite microbial degradation agent as well as a preparation method and application thereof. The degradation agent is prepared from Bacillus subtilis, Streptomyces thermodiastaticus, Bacillus stearothermophilus, Lactobacillus acidophilus, Saccharomyces cerevisiae, Enteromorpha protease, Methylobacterium radiora, Pantoea dispersa, Pseudomonas oryzihabitans,Citrobacter freundii and Staphylococcus cohnii. The mixed strain accounts for 15-25% of the total mass of the degradation agent, the mass percentage of water in the degradation agent is 10-20%, the pH value of the degradation agent is 5.5-8.5, and each gram of the degradation agent contains 106-109 viable bacteria. The degradation agent has the beneficial effects that: kitchen waste containing various substances such as vegetables, grains and meat can be effectively degraded, the activity of microorganisms in the degrading agent is high, the degrading rate reaches 80% or above, the degradingrate is high, the use amount is small when the kitchen waste is treated, generated peculiar smells are small, the cost is low, use is convenient, toxic and harmful substances are not generated, and safety, reliability and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a kitchen waste composite microbial degradation bacterial agent and its preparation method and application. Background technique [0002] In recent years, my country is in the rapid development of urbanization, and the urban population is growing at a relatively high rate every year. With the gathering of population, the discharge of urban waste is increasing, among which the proportion of kitchen waste is increasing year by year. Since food waste contains a large amount of starch, cellulose, protein, oil and other macromolecular organic substances and water, it provides a good living environment for various microorganisms, which in turn leads to the proliferation of germs, mosquitoes and other harmful organisms. This is extremely harmful to human health and the urban environment. Although kitchen waste has high utilization value, it has high moisture content and low calorific valu...

AI Technical Summary

Problems solved by technology

Although kitchen waste has high utilization value, it has high moisture content and low calorific value, which makes it inconvenient to collect, transport and incinerate. If it is not handled properly, it is easy to produce secondary pollutants such as leachate, which is perishable and produces stench

At present, for kitchen waste, the main way people adopt is to discard it directly or smash it through garbage treatment equipment and then flush it directly into the sewage pipe. The garbage treatment mainly adopts biological treatment technologies such as unified landfill and incineration, which have poor efficiency and require The reuse rate is low, which is not conducive to environmental protection, especially for kitchen waste, which lacks targeted special treatment, and fails to recycle sugar, protein, starch, cellulose and other substances in kitchen waste
