Treatment method of kitchen waste

Abstract

The present invention relates to a treatment method of kitchen waste. The treatment method comprises the following steps: materials not eaten by hermetia illucens in the kitchen waste are sorted out, no dehydration and oil separation is conducted, and the kitchen waste is directly crushed into a kitchen waste slurry material at a particle size smaller than or equal to 3 mm, and a water content of the slurry material is 75-90%; the kitchen waste slurry material is placed in a bio-converter and deodorizing microorganisms and hermetia illucens larvae are inoculated; a temperature of the bio-converter is controlled at 25-35 DEG C and an air relative humidity is controlled at 60-75%; the kitchen waste slurry material in the bio-converter is subjected to a hermetia illucens abdomen digestion for 8-10 days to be converted into an organic fertilizer; and the hermetia illucens larvae and organic fertilizer in the bio-converter are sieved into the hermetia illucens larvae and organic fertilizer. The treatment method is simple, practical and highly efficient, free of productions of waste water during the whole treatment processes, low in electricity consumption, only has the electricity consumption of 30 degrees for handling one ton of the kitchen waste, can convert all organic matters of the kitchen waste, and realizes a reduced, harmless and recycling utilization.

Description

technical field [0001] The invention relates to a kitchen waste treatment method, which belongs to the field of recycling and utilization of waste resources. Background technique [0002] Most of the existing kitchen waste is mixed with domestic waste and discarded or landfilled. Kitchen waste is rich in organic matter, high in water content and rich in organic matter, which is easily corrupted. Corrupted kitchen waste will pollute the environment. There are landfill methods, composting methods, incineration methods, fermented feed methods, and biogas fermentation methods to deal with kitchen waste. These methods all have problems of one kind or another to varying degrees. From an economic point of view, the economic benefits produced by these methods are relatively poor, and the resource utilization rate is low. The landfill method takes up a large amount of valuable land resources, and this treatment method neither reduces the amount nor completely eliminates the hazard....

Patent application number 2014102429308 introduces a device for breeding black soldier flies by eating kitchen waste, which has poor practicability

CN102350433A introduces a process for processing kitchen waste by black soldier flies. It is essentially a device, and a large amount of auxiliary materials need to be added in the processing process (the ratio of food waste: auxiliary materials is 1:0.25~1) to increase the processing efficiency. cost
