Problems solved by technology

[0005] The sewage treatment in the prior art usually adopts a single treatment method. The biological method mainly degrades the organic matter in the sewage, and the electrochemical method mainly converts the insoluble suspended matter into harmless substances. The two methods are not used at the same time, which affects The purification efficiency of sewage treatment is reduced, the water quality after sewage treatment is difficult to guarantee, and the use effect of sewage treatment is not good

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device based on electrochemical and biological filtration. The sewage treatment device comprises a water inlet pipe, wherein a filter assembly is arranged in the middle of the water inlet pipe, an electrochemical reaction tank is communicated with the right end of the water inlet pipe, a sedimentation tank is arranged at the right end of the electrochemical reaction tank, a biological filter tank is arranged at the right end of the sedimentation tank, a clean water tank is arranged at the right end of the biological filter tank, and the filter assembly comprises a filter screen. According to the invention, impurities and garbage in raw water are blocked through a filter screen, penetrate through a through groove, fall into a collecting box, enter a collecting frame to be collected and are subjected to electrochemical reaction treatment through a pole plate after entering an electrochemical reaction tank, the treated water enters a sedimentation tank to be settled, and sludge is discharged to the outside through a discharging pipe through an auger, so that the sewage is subjected to electrochemical reaction treatment and then biological treatment, synchronous use of the two methods is facilitated, the purification efficiency of sewage treatment is remarkably improved, the quality of treated water is better, and the use effect of sewage treatment is better.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device based on electrochemical and biological filtration. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Summarized into physical, chemical and biological methods. [0003] Electrochemical treatment is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer. The basic principle is to convert harmful substances in wastewater into harmless substances through electrolysis to achieve purification. W...
