Rural domestic garbage composting device based on tipping bucket type composting tanks and composting method thereof

Abstract

The invention provides a rural domestic garbage composting device based on tipping bucket type composting tanks and a composting method thereof. A pretreatment chamber is provided with a garbage secondary sorting area and a crusher, and an outlet of the crusher is connected with a main fermentation chamber through a belt conveyor; more than three movable tipping bucket type composting tanks are sequentially arranged in the main fermentation chamber, a feeding and discharging chamber is arranged between the main fermentation chamber and a post-fermentation chamber, and more than three fixed tipping bucket type composting tanks are arranged in the post-fermentation chamber; the bottoms of the main fermentation chamber and the post-fermentation chamber are respectively provided with a leachate collecting branch tank and a leachate collecting main tank, the leachate collecting main tanks are communicated with a water collecting well and a eachate collecting pool, and the leachate collecting pool is respectively communicated with a leachate back-spraying pipe of the main fermentation chamber and a leachate back-spraying pipe of the post-fermentation chamber through pumps. After secondary sorting, organic household garbage is added into the movable tipping bucket type composting tanks to complete main composting fermentation, and then fermentation and decomposition are conducted after turning. According to the method, recycling, reduction and harmlessness of the household garbage can be realized.

Description

technical field [0001] The invention belongs to the technical field of domestic waste treatment, and in particular relates to a rural domestic waste composting device based on a tipping bucket type composting tank and a composting method thereof. Background technique [0002] At present, the focus of domestic waste removal and harmless treatment in my country is still in cities, and rural domestic waste has not been properly disposed of. Most rural domestic waste, such as kitchen waste, yard waste, and vegetable peels, is disposed of by simple landfill, open-air dumping, and open-air incineration. These disposal methods not only cause a huge waste of resources, but also seriously affect environmental sanitation. Cause air, water and soil pollution. The treatment mode of rural domestic waste should not be copied from the treatment mode of urban domestic waste. Due to the vast land and sparse population in my country's rural areas, backward infrastructure, complex and serious...
