A light and simplified energy-saving and emission-reducing aerobic and anaerobic composting system for multiple wastes

Abstract

The invention relates to a light, simplified, energy-saving, emission-reducing, aerobic and anaerobic composting system for multiple wastes, which includes a frame, a cylindrical fermentation bin and a ventilation-crushing composite device. The fermentation bin is sealed and installed on the frame. The fermentation chamber is divided into three layers from the outside to the inside, followed by leachate anaerobic fermentation chamber, ventilation chamber and material aerobic fermentation composting chamber, the bottom of the ventilation chamber is provided with a rebound water barrier, the ventilation The pulverizing compound device is set in the material aerobic fermentation composting chamber, and the gas produced in the fermentation chamber is discharged after being treated up to the standard. The invention can carry out the harmless cleaning treatment of the perishable organic waste in the unit of villages and towns and households.

Description

technical field [0001] The invention relates to a system capable of performing aerobic and anaerobic composting on multiple wastes such as perishable garbage, kitchen waste and end vegetables, and belongs to the technical field of domestic garbage treatment. Background technique [0002] According to the survey by the Ministry of Health, the current scale of domestic waste generation in rural areas in my country is about 300 million tons per year. However, according to statistics from the Ministry of Housing and Urban-Rural Development, in 2016, the harmless disposal rate of domestic waste in my country's administrative towns and townships was only 44.99% and 15.82%, and only 62.2% of administrative villages treated domestic waste. Freshly produced domestic garbage and old garbage have encroached on a large amount of land, even farmland, and pollution of surface water, groundwater, soil and air is widespread. [0003] According to statistics, the per capita generation of ru...

Problems solved by technology

In rural areas with relatively rich land resources, sanitary landfills for domestic waste have been planned and established in towns or counties, but many of them are only simple landfills, and there are hidden dangers of secondary pollution such as leachate and heavy metals.
