Plastic electroplating comprehensive wastewater treatment system and treatment method thereof

Abstract

The invention discloses a plastic electroplating comprehensive wastewater treatment system and a treatment method thereof. Through arranged cyanogen-based wastewater treatment unit, an acid-alkali wastewater treatment unit, a chromium-based wastewater treatment unit, a complex wastewater treatment unit, an acid nickel wastewater treatment unit and an acid copper wastewater treatment unit, the plastic electroplating comprehensive wastewater treatment system can perform unified treatment on electroplating wastewater and effectively removes heavy metal ions and organic pollutants in the electroplating wastewater, so that through the multiple arranged treatment units, the reuse rate of the electroplating wastewater is effectively improved, wastewater discharge is reduced, and the electroplating wastewater accords with the demands on energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the technology in the field of waste water treatment, in particular to a plastic electroplating comprehensive waste water treatment system and a treatment method thereof. Background technique [0002] The electroplating industry is an important part of the cultural industry. The improvement of economic development and people's material and cultural level will inevitably require the electroplating industry to adapt to it. Many places have identified electroplating as an urban industry, which has enhanced the important position of electroplating in the regional economy; however, the environmental pollution caused by the electroplating industry is also very serious, making the shortage of water resources and water pollution more serious. The treatment of waste reduction and reuse of wastewater is very important. [0003] At present, the treatment methods for cyanide-containing wastewater, acid-base wastewater, chromium-containing...

AI Technical Summary

Problems solved by technology

[0003] At present, the treatment methods for cyanide-containing wastewater, acid-base wastewater, chromium-containing wastewater, acid-copper wastewater, nickel-containing wastewater and complex wastewater in electroplating wastewater are unreasonable and cannot be treated uniformly, and heavy metal ions and The removal of organic pollutants leads to a low reuse rate of electroplating wastewater, increased discharge, and high energy consumption. The discharge of treated electroplating wastewater is very harmful and pollutes the surrounding ecological environment.
