Aquaculture tail water composite microbial purification treatment device

Abstract

The present application relates to the field of sewage treatment, and more particularly to a compound microbial purification treatment device for aquaculture tail water. The compound microbial purification treatment device for aquaculture tail water comprises a support, a solid-liquid separator and the like; a solid-liquid separator, a dosing machine and a reaction tank are sequentially installed on the upper portion of the support from left to right; the solid-liquid separator, the dosing machine and the reaction tank are sequentially communicated; the solid-liquid separator is internally provided with a staged filtration structure and a backwashing structure. The present application performs staged filtration on the tail water through the solid-liquid separator, which can reduce the burden of filter frame filtration and prevent the filter frame from being blocked due to excessive impurities. Through the backwashing structure, the impurities are flushed into the blowdown pipe by the V-shaped plate and then discharged out of the equipment through the blowdown pipe, so as to achieve the effect of timely cleaning the filter frame and prevent the filter frame from being blocked, thereby ensuring the continuous filtration of the tail water. The dosing machine continuously divides, rotates and then divides again in the reverse direction to mix the liquid.
