Description
Technical Field

Copper-containing wastewater is the most common industrial wastewater and generally comes from the fields of metallurgy, surface treatment, mechanical processing and the like. Copper ions in wastewater are biologically toxic and cannot be effectively degraded in nature. The untreated high-concentration copper-containing wastewater is discharged into nature, so that not only is metal resource waste caused, but also water and soil are polluted, and the polluted water and soil enter a food chain after being biologically enriched, so that the health of human beings is harmed. At present, common copper-containing wastewater treatment methods include a precipitation method, an electrochemical method, an adsorption method, a membrane filtration method, an ion exchange method and the like. However, the precipitation method consumes a large amount of chemical agents, and also generates hazardous waste copper-containing sludge, which is not economical and environment-friendly enough, and the general ion exchange method is suitable for treating low-concentration copper-containing wastewater.

Therefore, the electrodeposition method is suitable for treating high-concentration copper-containing wastewater and recovering high-quality metallic copper.
The electrocoagulation technology is characterized in that under the action of direct current, metals such as iron and aluminum are oxidized and corroded as anodes to generate metal ions such as iron and aluminum, and finally flocculants such as hydroxides, various hydroxyl complexes and polynuclear hydroxyl complexes are formed through a series of hydrolysis, so that impurities and metal ions in wastewater are adsorbed and coagulated and precipitated. The electric flocculation has good treatment effect on copper ions in wastewater, does not need to add chemical agents, is environment-friendly and economic, but has limitation on low-concentration copper ion treatment efficiency due to higher energy consumption.

The membrane filtration technology is widely applied to the treatment of metal ion wastewater, but has the problem of membrane pollution.
