Embodiment 1

[0029] An embodiment of the present invention's microbial agent for degrading kitchen waste, the specific implementation process is as follows:

[0030] (1) Bacteria culture

[0031] Inoculate Bacillus subtilis and lactic acid bacteria in fermenter culture medium (containing tryptone 10g / L, yeast extract 5g / L and sodium chloride 10g / L, pH 6-6.8), culture at 60°C for 15-24 hours, and measure The light absorption of the fermentation broth was in the logarithmic phase of growth. The Bacillus subtilis was preserved on January 9, 2020 at the Guangdong Provincial Microbial Culture Collection Center, address: 5th Floor, Building 59, Compound, No. 100 Xianlie Middle Road, Guangzhou City; the preservation number is GDMCC No.60963.

[0032] (2) Preparation of microbial agents

[0033] The above prepared Bacillus subtilis fermentation broth and lactic acid bacteria fermentation broth are mixed at a mass ratio of 2:1 to obtain a composite strain; the composite strain and wood bran are m...

Embodiment 2

[0041] An embodiment of the microbial bacterial agent for degrading kitchen waste according to the present invention, in this embodiment, except that the composite bacteria are prepared by mixing the fermentation liquid of Bacillus subtilis and the fermentation liquid of lactic acid bacteria at a mass ratio of 1:1, the remaining ratios and steps are the same as Example 1 is the same.

[0042] In this example, M 2 , W 2 The quality of impurities is the same, both are 0.98kg, and the quality of microbial agent is M 3 for 10kg, W 1 The mass is 70kg, M 1 The mass is 20.01kg; according to the formula, the degradation rate of this embodiment is 86.93%.

Embodiment 3

[0044] An embodiment of the microbial bacterial agent for degrading kitchen waste of the present invention, except for the following degradation experiment, all the other methods and steps are the same as in Example 1; the degradation experiment process of the present embodiment is as follows:

[0045] Remove the non-degradable plastic spoons and chopsticks, large bones and other hard wastes in the leftover food paper of the work meal; put 10kg of the microbial agent prepared in the above example into the auxiliary degradation equipment; add 5kg of kitchen waste, Continuously degrade at 41-79°C for 24 hours, add the same amount of kitchen waste for degradation, and repeat the degradation process ten times in total. The mass ratio of the total kitchen waste added to the microbial agent was 5:1, and the degradation rate was calculated according to the formula in Example 1.

[0046] In this example, M 2 , W2 The quality of impurities is the same, both are 0.94kg, and the quality...

Abstract

The invention discloses a microbial bacterial agent for degrading kitchen waste, including Bacillus subtilis, lactic acid bacteria and a carrier. The Bacillus subtilis has the functions of secreting and producing various enzymes for degrading kitchen waste materials and utilizing various acid substances. It was preserved in the Guangdong Provincial Microbial Culture Collection Center on January 9, 2020, with the preservation number GDMCC No.60963; it cooperates with lactic acid bacteria to form an effective circulation system, and carries out aerobic fermentation under high-temperature operation. Excellent carrier, significant degradation effect, 24h degradation rate between 84%-95%; the microbial agent treatment method of the present invention is simple, the degradation effect on kitchen waste is stable, high efficiency, and the degradation product has no pollution to the environment, The degradation products obtained from the degradation treatment are semi-finished products with high organic matter content, which can be further utilized in many aspects such as the preparation of organic fertilizer raw materials.

Description

technical field [0001] The invention belongs to the technical field of microbial agents, and relates to a microbial agent, in particular to a microbial agent for degrading kitchen waste and its application. Background technique [0002] With the continuous advancement of the urbanization process in our country, the garbage produced by urban residents is increasing day by day. Among these garbage, kitchen waste accounts for more than 40%, and the proportion is increasing year by year. Kitchen waste, commonly known as swill, swill, also called swill or rancid water, is a general term for food waste and kitchen waste; its composition is complex, including oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones and waste A mixture of various substances such as cutlery, plastic, paper towels, etc. Since kitchen waste is easy to deteriorate and rot, it is easy to breed mosquitoes and flies, causing the spread of germs and water pollution. Improper treatment will ser...
