Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis acidification tanks, in particular to a mixed hydrolysis acidification tank. Background Art

[0002] The hydrolysis acidification tank is a device used for wastewater treatment. The anaerobic degradation process of organic matter in wastewater can be divided into four stages: hydrolysis stage, fermentation (or acidification) stage, acetogenesis stage and methanogenesis stage. Hydrolysis refers to the biochemical reaction carried out outside the microbial cell before the organic matter enters the microbial cell. The microorganism completes the biocatalytic reaction by releasing extracellular free enzymes or fixed enzymes linked to the outer wall of the cell.

[0003] When the hydrolysis acidification tank is working, the sewage in the hydrolysis acidification tank needs to be stirred to keep the sludge in the hydrolysis acidification tank in a suspended state. Most of the stirring devices in the existing hydrolysis acidification tanks use a fan aeration stirring system. Although the sewage in the hydrolysis acidification tank can be stirred, a large amount of oxygen will be added to the sewage during the aeration process, which will increase the dissolved oxygen content in the sewage in the hydrolysis acidification tank, which is not conducive to the degradation of organic matter in the hydrolysis acidification tank, affects the sewage hydrolysis effect, and is inconvenient to use. Utility Model Content

Through the provided mixing assembly, the sludge in the acidification tank can be fully mixed and stirred, and the inner wall of the acidification tank can be scraped to prevent the sludge from adhering to the inner wall of the acidification tank, thereby ensuring good sewage hydrolysis effect and easy use.

[0006] According to the hybrid hydrolysis acidification tank, the filter mesh is located above the acidification tank body.
