Kitchen waste treatment method and device

Abstract

The invention discloses a kitchen waste treatment method and device. The device comprises a feeding module, a fermentation module, heating modules, an oil-water separation module, a screening module,a granulation module and a waste treatment module which are connected with one another, wherein an output end of the feeding module is connected with an input end of the fermentation module, the heating modules are arranged on the periphery of the fermentation module to control the temperature in the fermentation module, one output end of the fermentation module is connected with an input end of the oil-water separation module, and the other output end of the fermentation module is connected with the screening module, the screening module is used for screening solid materials processed by thefermentation module, an output end of the screening module is connected with an input end of the granulation module, the waste output ends of the fermentation module, the automatic screening module and the oil-water separation module are connected with an input end of the waste treatment module. According to the method and the device, the integrated treatment and accurate fermentation of kitchen waste are realized, the pollution and transferring of separated oil are avoided, and the operation cost of kitchen waste treatment is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to the treatment of kitchen waste, in particular to a kitchen waste treatment method and equipment. Background technique [0002] Food waste includes two categories: food waste and kitchen waste. With the continuous growth of the global population base and the improvement of people's living standards, the discharge of food waste is increasing day by day. Kitchen waste comes from the daily life of residents and is characterized by a large amount. The main difference between food waste and ordinary waste is that food waste has a high moisture content and a high content of organic matter. [0003] At present, the commonly used technologies include resource utilization technologies such as aerobic microbial degradation treatment, high-temperature composting and anaerobic digestion treatment, but the above-mentioned methods need to carry out pre-procedures such as manual screening,...
