Hydrolysis acidification reaction tank for waste treatment

Abstract

The invention discloses a hydrolytic acidification reaction tank for waste treatment, which comprises a tank body, the middle position of the top of the tank body is connected with a rotary drum through a bearing, the top of the rotary drum is provided with a driving mechanism, the inner wall of the rotary drum is inserted with a fixed rod, and a limiting structure is arranged between the outer wall of the fixed rod and the inner wall of the rotary drum. A water seepage net is connected to the bottom of the outer wall of the fixing rod through a bearing, the circumferential outer wall of the water seepage net is matched with the circumferential inner wall of the tank body, and a mixing structure is arranged on the outer wall, close to the top of the water seepage net, of the fixing rod. The problem that water cannot be effectively fed into the liquid guide pipe due to the fact that the height of impurities such as sludge and dirt in the tank body exceeds the bottom of the liquid guide pipe is solved, the top of the tank body can be stirred by utilizing an arc-shaped frame and a stirring blade, and the top of a water seepage net is brushed by utilizing a brushing plate; the drainage speed of the whole tank body is higher, and the problem of blockage of the sludge discharge pipe is avoided.

Description

technical field [0001] The invention relates to the technical field of waste sewage treatment, in particular to a hydrolysis acidification reaction tank for waste sewage treatment. Background technique [0002] Hydrolysis refers to the biochemical reaction outside the cell before the organic matter enters the microbial cell. Acidification is a typical fermentation process, and the metabolites of microorganisms are mainly various organic acids. Mechanistically speaking, hydrolysis and acidification are two stages of anaerobic nitrification process, but different processes have different treatment purposes of hydrolysis and acidification. The purpose of hydrolysis in the hydrolytic acidification-aerobic biological treatment process is mainly to convert the non-dissolved organic matter in the original wastewater into dissolved organic matter, especially in industrial wastewater, mainly to convert the difficult-to-biodegradable organic matter into easily biodegradable organic m...
