Kitchen waste treatment method

Abstract

The invention provides a kitchen waste treatment method, and relates to the technical field of kitchen waste treatment. The kitchen waste treatment method comprises the following steps that S1, winnowing treatment is carried out, specifically, kitchen waste is aired and separated through a winnowing machine, screened plastic products and organic waste are classified, and untreatable waste such asglass ceramics is removed, S2, crushing treatment is carried out, specifically, the organic waste is crushed, then hot melting treatment is carried out on the plastic products, then pelleting is carried out, and finally, thermal power treatment is carried out in an incinerator; and S3, mixed fermentation is carried out, specifically, zymophyte is activated, mixed and stirred with the organic waste. The organic waste is crushed and reutilized, the utilization rate of kitchen waste can be increased, and resource waste caused by the fact that the utilization method of the remaining kitchen wasteis not in place is avoided; and power generation is achieved through crushing and combustion of plastic, the treatment efficiency can be improved, and environmental pollution caused by bacteria breeding due to accumulation of a large amount of waste is avoided.

Description

technical field [0001] The invention relates to the technical field of domestic kitchen waste treatment, in particular to a kitchen waste treatment method. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, cafeterias, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to perish and produces stench. After proper treatment and processing, it can be transformed into It is a new resource with high organic matter content, which can be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels. [0003] At ...

Problems solved by technology

[0003] At present, most cities use composting or landfill for waste treatment. For untreated kitchen waste, composting is used. The general treatment cycle is longer, and in the actual treatment process, the utilization of resources The rate of liquid is not high, and in the process of composting, there is a certain impact on the environment, so it is more difficult to select a site, and secondly, the amount of one-time treatment is limited, and a large amount of treatment cannot be carried out. With the improvement of residents' living standards in recent years , a large amount of kitchen waste was generated, resulting in a large amount of kitchen waste that could not be disposed of in time on site, resulting in the breeding of bacteria and mosquitoes
