Problems solved by technology

However, this treatment method cannot fully recycle and utilize the rich nutrients in kitchen waste, which will cause waste of resources and poor economic benefits; at the same time, due to the high moisture content, high salt content and high oil content of kitchen waste, it will also lead to composting. Poor quality and secondary pollution problems

Embodiment 1

[0039] A high-temperature degradation treatment method for waste based on microbial flora, specifically comprising the following steps:

[0040] Step 1: Put the Bacillus thermophilic bacteria isolated and screened from the kitchen waste microbial treatment system into the culture medium, after culturing for 5 hours, absorb the bacteria liquid through corn flour, keep it warm and proliferate at 55 degrees for 6 hours, and then dry to prepare the bacterial agent ;

[0041] Step 2: Classify the kitchen waste, separate the impurities in the kitchen waste, and filter the kitchen waste, and separate the sewage in the kitchen waste;

[0042] Step 3: Put the separated kitchen waste and distilled water into the reaction tank according to the ratio of 25:1, and put in 5% bacterial agent for stirring, and detect the carbon-nitrogen ratio of the mixture, and process the mixture according to the carbon-nitrogen ratio;

[0043] When the carbon-nitrogen ratio is less than 10, add organic wa...

Embodiment 2

[0047] Step 1: Put the Clostridium thermophilic bacteria isolated and screened from the kitchen waste microbial treatment system into the culture medium, after culturing for 10 hours, absorb the bacteria liquid through the wine tank powder, heat and proliferate at 60 degrees for 8 hours, and then dry to obtain the bacteria agent;

[0048] Step 2: Classify the kitchen waste, separate the impurities in the kitchen waste, and filter the kitchen waste, and separate the sewage in the kitchen waste;

[0049] Step 3: Put the separated kitchen waste and distilled water into the reaction tank according to the ratio of 15:1, and put in 15% bacterial agent for stirring, and detect the carbon-nitrogen ratio of the mixture, and process the mixture according to the carbon-nitrogen ratio;

[0050] When the carbon-nitrogen ratio is less than 10, add sludge to adjust;

[0051] When the carbon-nitrogen ratio is greater than 25, continue to add distilled water to the garbage to dilute the carbon-...

Embodiment 3

[0054] A high-temperature degradation treatment method for waste based on microbial flora, specifically comprising the following steps:

Abstract

The invention discloses a garbage high-temperature degradation treatment method based on a microbial community. The garbage high-temperature degradation treatment method comprises the steps of: putting thermophilic bacteria separated and screened from a kitchen garbage microbial treatment system into a culture medium for culturing; and mixing the cultured product with distilled water and kitchen garbage, and putting the mixture into a reaction tank for sealing, and degrading crude fat and crude fibers in the garbage through high-temperature heating. According to the garbage high-temperature degradation treatment method, most organic matters in the kitchen garbage can be degraded by means of the separated high-temperature microbial inoculum within 24 hours; the thermophilic bacteria have degradation enzymes with thermal stability, higher activity and higher metabolic rate, the fermentation temperature can be maintained at 75-85 DEG C or above, pathogenic microorganism can be killed moreeffectively, the sanitation requirements can be met, the degradation rate of organic substances can be accelerated, the treatment efficiency can be improved, and the production period can be shortened, so that the garbage high-temperature degradation treatment method based on the microbial community can be popularized and used.

Description

technical field [0001] The invention belongs to the technical field of high-temperature degradation of garbage, and in particular relates to a treatment method for high-temperature degradation of garbage based on microbial flora. Background technique [0002] Kitchen waste is a general term for leftover meals discarded by catering units such as families, hotels, restaurants, government agencies, enterprises and institutions. The daily output of kitchen waste in our country exceeds 20,000 tons. The daily output of kitchen waste in Shanghai alone reaches 1,200 tons, and that in Beijing is 1,600 tons. With the development of the catering industry, the output of kitchen waste is increasing rapidly. The method is still mixed and then buried or directly used to feed pigs. This method is easy to cause cross-infection of diseases between humans and animals. This traditional processing method can no longer meet people's requirements for health, environment and sanitation. Some citi...
