Chemical wastewater usually contains various organic, inorganic, heavy metal ions and other pollutants. In order to treat the wastewater, treatment equipment is very necessary.

[0003] The previous wastewater treatment methods had a relatively simple process and could not conveniently eliminate various harmful microorganisms such as bacteria and viruses in the wastewater, and did not have comprehensive treatment capabilities such as decolorization, decontamination, and sterilization.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model discloses a multi-stage treatment device for chemical electrolytic wastewater, which performs preliminary treatment on the wastewater through a security filter. The preliminarily filtered wastewater enters an electrochemical reactor. When the electrodes are energized, an electric field is formed in the electrochemical reactor.

A liquid pump 12 is arranged on the circulating water pipe 11. A safety filter 18 is connected to the top of the water inlet pipe 13 through a flange 19 and a connecting bolt 20.

[0023] When in use, the sewage is preliminarily treated through the security filter 18, and the preliminarily filtered sewage enters the electrochemical reactor 15. The electrode 23 forms an electric field in the electrochemical reactor 15 when power is turned on. Under the action of the electric field, the silicon carbide ceramic membrane 16 and the electrode 23 in the electrochemical reactor 15 will produce oxidants with extremely strong oxidizing ability. These oxidants react chemically and electrochemically with the organic pollutants in the water, breaking their organic molecular chains and converting large molecules into small molecules that are more easily degraded. Finally, they are completely mineralized and converted into carbon dioxide and water, so as to achieve the purpose of completely removing harmful organic pollutants, thereby achieving color, decontamination and sterilization effects.
