Organic trash microbiological treatment device

Abstract

The invention discloses an organic trash microbiological treatment device. The organic trash microbiological treatment device comprises a feeding hopper, a trash crushing mechanism, a cleaning mechanism, a solid-liquid separation conveying mechanism and a solid trash microbiological decomposition mechanism which are arranged in sequence, and is characterized in that the trash crushing mechanism comprises a crushing chamber, crushing cutter shafts, crushing cutters, a screen and a first motor; the cleaning mechanism comprises a conical hopper, multiple flushing spray heads, stirring wheel blades and a second motor; the solid-liquid separation conveying mechanism comprises a conveying cylinder, a conveying shaft and a third motor; and the solid waste microbial decomposition mechanism comprises a microbial reaction chamber, a stirrer and a fourth motor. The organic trash microbiological treatment device is used for microbial decomposition of organic trash, meanwhile, crushing and refining, desalting treatment and solid-liquid separation are conducted before microbial decomposition, the decomposition efficiency can be improved, and long-term use and efficient work can be guaranteed.

Description

technical field [0001] The invention belongs to a kind of organic garbage microbial treatment equipment. Background technique [0002] Municipal solid waste mainly refers to the solid waste generated by units and residents in the city in their daily life and life services. The amount of municipal solid waste generated in my country is increasing at a rate of 8%-10% every year. At present, the accumulated amount of urban domestic waste in my country has reached 6.2 billion tons. In 2004, the amount of urban domestic waste generated in China was close to 260 million tons, of which 80%-90% came from large and medium-sized cities. kg, its treatment rate is only about 50%, and more than 200 large and medium-sized cities have fallen into the siege of municipal solid waste. With the rapid development of the economy and the improvement of living standards, the proportion of recyclable waste and organic waste in municipal solid waste will gradually increase. In the process of garba...

Problems solved by technology

Due to the presence of harmful substances such as salt in food waste (which is not conducive to the survival, growth and activity of microorganisms), when the concentration of the above-mentioned harmful substances is too high and directly added to the fermentation tank (or) for microbial reactions, it will be serious. Destroying the living environment of microorganisms is very unfavorable to the growth, reproduction, and decomposition of microorganisms, and even seriously affects the survival rate or biological activity of microorganisms, resulting in low decomposition efficiency, incomplete decomposition of organic waste, odor, and short life span of microorganisms.
