Embodiment 1

[0043] The degrading bacterial agent of the present invention, its preparation method and application thereof comprise the following steps:

[0044] (1) Bacteria activation culture

[0045] First, respectively inoculate Bacillus subtilis, Bacillus lysine, and Bacillus licheniformis into beef extract peptone liquid culture medium for activation culture, place them in a constant temperature shaker at a temperature of 30-35°C and 180-220rpm for 1-2 Days, to logarithmic growth phase, to obtain activated liquid seed solution.

[0046] The formula of beef extract peptone liquid medium is as follows: beef extract 3g, peptone 10g, yeast extract 2g, sodium chloride 5g, ultrapure water 1000mL, pH7.4-7.6.

[0047] Then Trichoderma viride, Candida glabrata and Yarrowia lipolytica strains were respectively inoculated into potato glucose medium for activation culture, placed on a constant temperature shaker at a temperature of 20-25°C and 180-220rpm for 2 -4 days, to logarithmic growth ph...

Abstract

The invention provides a degrading bacterium agent for kitchen waste treatment. The degrading bacterium agent is prepared from the following components in parts by weight: 20 to 30 parts of bacillus subtilis, 10 to 15 parts of lysine bacillus, 10 to 20 parts of bacillus licheniformis, 15 to 25 parts of trichoderma viride, 5 to 10 parts of candida glabrata, 5 to 10 parts of yersinia lipolytica and1 to 5 parts of a biological surfactant. The invention further provides an application of the degrading bacterium agent in kitchen waste integrated treatment equipment. The degradation microbial inoculum can rapidly decompose proteins, grease, starch polysaccharides, cellulose, hemicellulose and other macromolecular organic matters in the kitchen waste, so that the macromolecular organic matters are rapidly stabilized, the degradation efficiency of the kitchen waste is improved, the space utilization rate of a fermentation bin is further improved, and the quality of the kitchen waste degradation product organic fertilizer is improved.

Description

technical field [0001] The invention relates to the field of urban waste treatment, in particular to a degrading bacterial agent for waste treatment in integrated kitchen waste treatment equipment and its application. Background technique [0002] With the rapid growth of my country's economy and the increasing level of residents' consumption, people's consumption in catering is increasing day by day, which has brought about a rapid increase in kitchen waste. In 2018, the national kitchen waste generation was about 108 million tons, with an average daily output of 292,000 tons / day, and a compound annual growth rate of over 8%. [0003] Kitchen waste is a general term for food waste and kitchen waste. Catering waste refers to the waste generated from various restaurants, hotels, hotels, and canteens of schools, enterprises and institutions during the food use process, as well as discarded leftovers, discarded edible oils and food residues, etc. Kitchen waste refers to the w...
