Abstract

This application relates to a method for comprehensive treatment of mixed sewage, which is applied in the technical field of sewage treatment and solves the problem that the debris in the sewage is not easy to clean up. It includes the following steps: Step 1: Drain the sewage; Clean up the sundries; step three: settle the impurities in the sewage; step four: purify the sewage. This application cleans the floating matter in the sewage to reduce the occurrence of the floating matter entering the mixing zone and affecting the operation of the stirring device, so as to improve the purification effect of the sewage.

Description

technical field [0001] The application relates to the technical field of sewage treatment, in particular to a method for comprehensive treatment of mixed sewage. Background technique [0002] At present, there are three main problems in the domestic water environment. One of them is water pollution, which causes serious organic pollution in most urban rivers. The sewage discharged by urban residents in their daily lives leads to a decline in the quality of urban water sources and an increase in treatment costs. Seriously threaten the drinking water safety of urban residents and the health of the people. [0003] The Chinese patent with the publication number CN106746381A discloses a river sewage treatment system, which includes a settling zone and a purification zone set in sequence, the settling zone includes a mixing zone and a gentle settling zone set in sequence, and the mixing zone includes The flocculant spraying device and stirring device; the bottom surface of the g...
