Abstract

The invention discloses a kitchen waste treatment method. The kitchen waste treatment method comprises the steps of kitchen waste sorting and crushing, microbial fermentation decomposition, oil-water separation, aeration air flotation separation, hydrolysis-anaerobic fermentation, A / O tank treatment, hydrolysis-MBR treatment and disinfection treatment. The effluent quality reaches the discharge or reuse standard, the whole treatment process is carried out at normal temperature, high-temperature drying is not needed, the defects that in the prior art, kitchen waste treatment needs high-temperature treatment, energy consumption is high, and the decrement rate is low are overcome, kitchen waste treatment in the normal-temperature aerobic environment is achieved, energy consumption is low, the decrement rate reaches up to 99%, final products obtained after organic matter decomposition are carbon dioxide and water, no secondary pollutant is generated, environmental pollution is reduced, and the environmental comprehensive treatment capability of kitchen waste treatment is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a kitchen waste treatment method. Background technique

[0002] With the rapid development of my country's economy and the gradual improvement of people's living standards, various catering service industries have gradually increased, and kitchen waste has increased. Food waste refers to the food waste and food waste produced by restaurants, hotels, various restaurants, government agencies, enterprises, institutions, schools and other public canteens, households, farmers' markets, and food processing enterprises. of organic waste. After being piled up, food waste will deteriorate, which not only emits rancid smell, but also causes waste water, waste oil, etc. to pollute the environment. After food waste decays, it will produce a large amount of harmful substances, including various bacteria that are harmful to humans and animals. , Food waste has bec...
