This invention relates to the field of environmental engineering technology and discloses a method for treating wastewater containing copper nitrate and copper sulfate from the high-purity copper industry. The method involves filtering the copper nitrate and copper sulfate wastewater into reaction tanks A and B respectively, adding flocculants, monitoring the pH value of the reaction tanks during the reaction process using online monitoring instruments, and separately adding hydrogen peroxide to reaction tank A to break down the complexed copper and convert it into Cu. 2+ The supernatant is used as effluent and treated by diffusion dialysis. Activated carbon adsorption and reverse osmosis separation are used to further remove residual copper ions. The sludge is washed eight times with circulating water. Based on sludge stabilization, the sludge is converted into organic fertilizer through composting. Bioleaching technology uses microorganisms or their metabolites to leach valuable metals from the sludge through interaction with the metals. The treated wastewater is neutralized and then discharged into a comprehensive wastewater pond. The recovered copper is electrolyzed to produce copper products with 98% purity.
