Perishable garbage microbial degradation technology

Abstract

The invention discloses a perishable garbage microbial degradation technology. The technology comprises the following steps of: 1, crushing perishable garbage, 2, preparing a microbial base material,3, activating microorganisms, 4, adding the mixed microbial base material into a microbial biochemical cabin, enabling the temperature in the microbial biochemical cabin to be kept between 25 DEG C and 35 DEG C, and completely activating the microbial activity, and 5, conducting normal operation of the microbial biochemical cabin: feeding the microbial biochemical cabin according to the rated treatment capacity every day, calculating and discharging degradation residues according to 5% of the rated treatment capacity before entering every day, and leaving other materials in the microbial biochemical cabin to serve as a microorganism bacterium bed. No secondary pollution is generated in the degradation process. The technology can work at normal temperature, and is energy-saving, environment-friendly and high in decrement rate. The moisture content of the produced solid organic matter is 50-75%, and the organic matter is rich, is rich in humic acid, is a good organic matrix, and can be used as an organic fertilizer composting auxiliary material to realize resource utilization.

Description

technical field

[0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a microbial degradation technology of perishable garbage. Background technique

[0002] Perishable organic waste is the most common waste produced in urban daily life. Its main components include organic matter such as starchy food, plant fiber, animal protein and fat. Smelly, not conducive to the characteristics of ordinary garbage truck transportation. If this kind of garbage is not treated by classification and special treatment, it will cause great harm to the environment.

[0003] With the rapid development of our country's economy and the gradual acceleration of urbanization, the output of perishable organic waste is showing an upward trend year by year. Using landfills takes up a lot of land, and at the same time produces secondary waste such as landfill leachate and landfill gas. pollute. Using the waste incineration mode, while losing heat energy...
