Abstract

The invention discloses electrochemical treatment and reclamation of electroplating acid copper wastewater. The electrochemical treatment and reclamation of the electroplating acid copper wastewater comprises the following steps: selecting an experiment instrument and a chemical agent; preparing an experiment agent; performing chemical experiment; and summarizing the experiment result and optimizing the technology. According to the electrochemical treatment and reclamation of the electroplating acid copper wastewater, an electrolysis mode is carried out to remove the electroplating acid copperwastewater, and the effect is obvious, and the removing rate is 99% or more; the treated solution can reach the standard for drainage; in addition, the product of the electroplating acid copper wastewater is copper chloride hydroxide, and the copper recovery rate is 90% or more, and thus the effect of electrolysis in treating the electroplating acid copper wastewater is good; and moreover, the process of removing copper ions in wastewater is simple, convenient, and easy to carry out; the cost is low; and a valid technical technology is supplied to treat the copper containing wastewater in theelectroplating industry.

Description

technical field [0001] The invention relates to the technical field of copper electroplating wastewater treatment, in particular to the electrochemical treatment and recycling of acid copper electroplating wastewater. Background technique [0002] The electroplating industry is an industry that is inseparable from my country's national economy and people's livelihood. According to statistics, there are more than 10,000 electroplating factories in my country. Compared with other industries, the copper content of electroplating wastewater is the highest, containing dozens or even hundreds of milligrams of copper per liter of wastewater. Therefore, the removal of copper electroplating wastewater is an urgent problem. As we all know, the treatment of electroplating acid copper wastewater must be carried out before its discharge, and it must be harmless before discharge. Due to the large discharge of copper electroplating wastewater and the economic value of metal copper itself...
