Problems solved by technology

The device can effectively improve the ordinary vertical water flow carbon nanotube membrane electrochemical filter reactor, increase the contact opportunity between pollutants and carbon nanotubes, and overcome the shortcoming of easy gas accumulation under high voltage, so as to improve the reaction efficiency and solve the problem of carbon nanotubes at the same time. The nanotube membrane material is not fixed firmly and is easily damaged

Description

technical field [0001] The invention is a high-efficiency electrochemical filtering reaction device capable of vertically passing the sewage and wastewater through the carbon nanotube membrane at a high flow rate. In particular, it is a high-throughput electrochemical filtration sewage treatment device. Background technique [0002] With the rapid development of population and industry, a large amount of organic pollutants have been discharged into water bodies, causing damage to the ecological environment. Therefore, it is necessary to develop new sewage treatment methods to effectively remove organic pollutants in sewage, especially toxic and harmful organic substances. [0003] The electrochemical method can effectively degrade organic pollutants in sewage and wastewater, and has the advantages of no need to add oxidants, flocculants and other chemicals, small equipment size, small footprint, simple and flexible operation, and small sewage discharge. Therefore, it has be...
