Description

Technical Field

[0002] The anaerobic tank is a treatment facility for high-concentration organic wastewater and sludge. Under anaerobic conditions, anaerobic microorganisms are used to degrade organic matter into simple inorganic substances. Glacial acetic acid is also called acetic acid. The anaerobic tank is mainly divided into four stages: hydrolysis stage, acidification stage, acetic acid production stage and ethane production stage. In the acidification stage, small molecular organic matter is converted into simple compounds such as volatile acids, alcohols, hydrogen, etc. in the cells of fermentation bacteria and acidifying bacteria. The products of the above stages are converted into acetic acid and other products. The accumulation of the products of the above stages in the anaerobic tank will acidify the reactor, especially in winter, reducing the anaerobic reaction rate. Severe acidification will cause the entire system to collapse. Therefore, it is necessary to heat the anaerobic tank to maintain the anaerobic reaction efficiency and avoid the accumulation of acidified products in the anaerobic tank to destroy the anaerobic reaction system.

The shaft sleeve 304 is fixed to the inner wall of the top of the anaerobic tank 1, and the fixed block 305 is fixed to the top bottom surface of the anaerobic tank 1. The output end of the servo motor 301 rotates through the shaft sleeve 304 and the fixed block 305. The output end of the servo motor 301 rotates through the top of the anaerobic tank 1, the shaft sleeve 304 and the fixed block 305, so that the rotation of the servo motor 301 is more stable.
