Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to an electro-biochemical membrane integrated sewage treatment device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily life of ordinary people. There are many methods and types of sewage treatment. Electro-biochemical membrane integrated sewage treatment is one of the common ones. Electro-biochemical membrane integrated sewage treatment is a technology that combines electrochemical and biological treatment to promote the effect of biological treatment through electrochemical processes to improve the efficiency and effectiveness of sewage treatment.

[0003] The existing electro-biochemical membrane integrated sewage treatment equipment usually uses electrical fillers and biological fillers to complete the sewage treatment. Directly injecting sewage into the equipment for treatment puts a heavy load on the electrical fillers and biological fillers, which will quickly cause the fillers to become less effective or clogged. Therefore, the use time of the electrical fillers and biological fillers will be greatly reduced. In order to ensure the sewage treatment effect, personnel are required to frequently replace the fillers, which is not conducive to use. In view of this, we propose an electro-biochemical membrane integrated sewage treatment equipment. Utility Model Content
