Pretreatment device for residential kitchen waste

Abstract

The invention relates to a pretreatment device for residential kitchen waste. The device comprises an inlet pretreatment component, a crushing device, a grinding chamber, a solid-liquid separation chamber, a fermentation device and an oil-water separation device. According to the device, by arranging the crushing device, the grinding chamber, the solid-liquid separation chamber and the fermentation device, primary treatment of the kitchen waste subjected to classification and delivery in residential communities can be realized; and after treatment, grease and primary fermentation fertilizers can be transferred while recycled water is returned to the residential communities as recycled water for use, so that the occurrence of mass propagation of microorganisms and foul smell during the transportation process of the kitchen waste can be avoided, in this way, the harmful turns into the beneficial, and the whole environment is improved.

Description

Technical field [0001] The invention belongs to the field of environmental protection, specifically the field of garbage recycling, and specifically relates to a pretreatment device for household kitchen waste. Background technique [0002] Sorting and disposing of garbage has become the mainstream of the society. Among them, kitchen waste accounts for the largest proportion of the garbage generated by residents. The current way of treating garbage after classification is to transport it to different garbage treatment plants for separate treatment, but For kitchen waste, because the internal organic matter is very complex and there are a large number of microorganisms remaining, the microorganisms in it will multiply during the transportation process, which will have a great negative impact on the working environment of transport vehicles and transport personnel. Due to the breeding of large numbers of harmful microorganisms, it is more difficult to kill microorganisms in subsequ...

[0002] Sorting and disposing of garbage has become the mainstream of society. Among them, kitchen waste accounts for the largest proportion of the garbage generated by residents. At present, the treatment method of sorted garbage is to transport it to different garbage treatment plants for separate treatment, but For kitchen waste, because the internal organic matter is very complex and there are a large number of microorganisms remaining, the microorganisms in it will multiply during the transportation process, which will have a great negative impact on the working environment of the transport vehicles and transport personnel. At the same time Due to the proliferation of harmful microorganisms in large numbers, the difficulty of killing microorganisms in the subsequent treatment is greatly increased. If the deodorization primary treatment can be carried out in residential areas before classification and transportation, the occurrence of the above problems will be greatly improved.
