Electroplating wastewater treating device

Abstract

The invention belongs to the field of electroplating wastewater treating equipment, and particularly relates to an electroplating wastewater treating device. The device comprises a reaction pool composed of a shell and a partition plate. The partition plate divides the shell into an upper shell body and a lower shell body. The partition plate is provided with a first drainage outlet located on the side, connected with the upper shell body, of the partition plate. The lower shell body is provided with a screen net filtration mechanism and an activated carbon filtration mechanism located on the side, in the water outlet direction, of the screen net filtration mechanism. The upper shell body and the lower shell body are each provided with a medicament barrel and an electrolyzer which are communicated with the interior of the reaction pool. According to the electroplating wastewater treating device, the structure is compact, space is saved, the using cost is reduced for the enterprise, and electroplating wastewater can be sufficiently and effectively purified through the arrangement of the screen net filtration mechanism, the activated carbon filtration mechanism, the electrolyzer and the like.

Description

technical field [0001] The invention belongs to the field of electroplating wastewater treatment equipment, in particular to an electroplating wastewater treatment device. Background technique [0002] Electroplating wastewater contains a large amount of heavy metal ions such as chromium, zinc, copper, cadmium, lead, nickel, and highly toxic substances such as acids, alkalis, and cyanides. Some of them also contain highly toxic substances that are carcinogenic, teratogenic, and mutagenic, such as Cyanide can cause acute poisoning of humans and animals, and cause death. Long-term effects at low concentrations can also cause chronic poisoning; hexavalent chromium can cause lung cancer, gastrointestinal diseases and anemia, and will accumulate in bones, spleen and liver; It is extremely necessary to recycle it as a huge threat to safety. [0003] The current electroplating wastewater treatment equipment is mainly composed of adjustment tank, dosing tank, reduction tank, neutra...

Problems solved by technology

[0004] Aiming at the problem of large footprint, an electroplating wastewater treatment machine with the application number CN201520322196.6 is currently disclosed, but while saving space, it only reacts with chemicals in the same reaction pool when treating wastewater, and then After one filtration treatment, there is a problem that the treatment effect of electroplating wastewater is not ideal.
