Compound microbial agent as well as processing method and application thereof

Abstract

The invention relates to a compound microbial agent which comprises compound bacteria for decomposing kitchen wastes and auxiliary materials for solid fermentation, wherein the compound bacteria comprise 10-15 parts of cellulose degradation bacteria, 15-30 parts of starch degradation bacteria, 15-20 parts of protein degradation bacteria, 15-20 parts of grease degradation bacteria, 10-15 parts of bacillus subtilis and 5-15 parts of pseudomonas aeruginosa; the auxiliary materials comprise 50-60 kg of wheat bran, 15-20 kg of bean pulp, 0.4-0.6 kg of magnesium sulfate, 0.4-0.6 kg of potassium dihydrogen phosphate, 0.1-0.2 kg of disodium hydrogen phosphate and 8-10 kg of glucose. The inoculation amount of the compound bacteria in the auxiliary materials is 0.8%-1%, and the compound bacteria is subjected to solid fermentation to obtain the compound microbial agent. The compound microbial agent has a good decomposing effect on greases, proteins and fiber substances and can be tolerant to salt with a certain concentration; optimally, the degradation rate can reach more than 90%.

Description

technical field

[0001] The invention relates to a microbial composite bacterial agent, in particular to a microbial composite bacterial agent for decomposing kitchen waste, as well as its treatment method and application. Background technique

[0002] At present, a considerable proportion of food waste is illegally collected and transported to feed pigs or enter underground workshops to extract "gutter oil". After being mixed with other domestic waste, the "mixed waste" produced hinders the effective recycling and recycling of domestic waste. use. my country's food waste has the characteristics of "four excesses and one miscellaneous", that is, large amount, high water, high oil, high salt and complex components. It is one of the most difficult food waste to deal with. Due to the different characteristics of food waste in my country and foreign countries, the mature microbial strains used in the treatment of food waste in foreign countries cannot give full play to their ori...
