Title:
METHOD FOR TREATING COMPREHENSIVE ELECTROPLATING WASTEWATER
Document Type and Number:
WIPO Patent Application WO/2021/102824
Kind Code:
A1
Abstract:
Disclosed is a method for treating comprehensive electroplating wastewater. By effectively and comprehensively treating acid wastewater, pre-treatment wastewater, cyanide-containing wastewater and chromium-containing wastewater, the chemical oxygen demand in the wastewater is effectively reduced, and the total amount of ammonia nitrogen and the total phosphorus content in the wastewater is effectively removed. The water quality of the treated wastewater meets the requirements for reuse. 80% of the total amount of wastewater after treatment can be reused for use in an electroplating production line, thus cutting down on the wasting of water resources and reducing environmental pollution.
