A constant pressure dissolved oxygen electroflocculation sewage treatment equipment

Abstract

The present invention relates to the technical field of sewage treatment, in particular to a constant-pressure dissolved oxygen type electro-flocculation sewage treatment equipment, including a sewage bucket, a drain pipe is connected to the top of the sewage bucket, and a filter is installed at the input end of the drain pipe. The sewage bucket is provided with a water inlet structure and a return water structure, and a power mechanism is installed on the top of the sewage bucket; by repeatedly performing electro-flocculation treatment on the sewage, the flocculation effect of impurities in the sewage can be effectively improved. At the same time, through the dynamic electro-flocculation treatment of sewage, and the continuous washing of electrolytic metal plates with sewage, the deposition of impurities on the electrolytic metal plates can be effectively avoided, and impurities can be prevented from blocking and isolating the electrolytic metal plates and sewage, and the sewage treatment can be improved. speed and reduce power consumption.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a constant pressure dissolved oxygen type electroflocculation sewage treatment equipment. Background technique [0002] As we all know, electroflocculation wastewater treatment refers to the electrolysis of metals to metals to precipitate metal cations, and then through a series of hydrolysis, polymerization and oxidation processes of submetallic ions to develop into various complexes, so that colloidal impurities in wastewater, suspended Impurities are coagulated and precipitated and then separated. At the same time, the charged pollutant particles swim in the electric field, and some of their charges are neutralized by the electrodes to promote their destabilization and coagulation. When the wastewater is treated by electrolytic flocculation, not only colloidal impurities and suspended impurities are affected. Coagulation and precipitation, and due to the oxidation of ...

AI Technical Summary

Problems solved by technology

[0003] In the existing electrocoagulation sewage treatment, the electrolytic metal is usually static electrolysis. When the metal ions are flocculated on the impurities in the sewage, the impurities are easy to attach to the metal surface, resulting in the isolation of the metal and the sewage, which affects the sewage treatment speed. At the same time, the power consumption is large
