High-efficiency aerobic fermentation device of organic wastes

Abstract

The invention discloses a high-efficiency aerobic fermentation device of organic wastes. The high-efficiency aerobic fermentation device is characterized in that a storage bin is connected with material crushing and mixing equipment which is connected with a fermentation reaction bin; the fermentation reaction bin is internally provided with a stirring device, microbial strains are placed in the fermentation reaction bin which is connected with a blower; the fermentation reaction bin is internally provided with a temperature sensor and an oxygen concentration sensor; a finished-product output hole at the bottom part of the fermentation reaction bin is connected with a finished-product stack and the storage bin; a waste-gas exhausting hole at the top part of the fermentation reaction bin is connected with a waste-gas treating device; and a PLC controls the whole device. The high-efficiency aerobic fermentation device disclosed by the invention has the advantages that the occupied area is small, the fermentation period is short, the mechanization degree is high, tail gas has no secondary pollution, and a finished product meets the requirements on reduction, harmlessness, stabilization and recycling and reaches national standards in China.

Description

technical field [0001] The invention belongs to the field of urban organic waste treatment, and in particular relates to a high-efficiency aerobic fermentation device for urban organic waste such as urban domestic waste, kitchen waste, sewage plant sludge and intensive livestock and poultry manure. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, cities have produced a large amount of organic waste, such as domestic waste, kitchen waste, sludge from sewage plants and intensive livestock manure, etc. Stable and perishable, and contains a variety of pathogenic microorganisms, parasite eggs, etc. [0003] Proper treatment must be carried out to avoid secondary pollution. The main treatment methods are incineration, landfill, aerobic fermentation and so on. [0004] Because landfilling requires a large area of ​​land, [0005] The leachate contains toxic substances and is difficult to deal with; the investmen...

AI Technical Summary

Problems solved by technology

In the current aerobic fermentation process of organic waste, the common problems are: large area, long fermentation cycle, low degree of mechanization, tail gas is easy to cause secondary pollution, and the final product cannot be reduced or harmless. , stabilization, resource utilization requirements and national standards, etc., have seriously hindered the popularization and application of aerobic fermentation technology in organic waste treatment and resource utilization
