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...
