non-ferrous elting, electronic materials and other industries often contain a large number of divalu copper ions. Because of the large discharge of copper-containing wastewater and the high economic value of metal copper, it is beneficial to both environmental management and resource recycling if copper-containing wastewater can be discharged to the standard discharge (0.5mg/l) at the same time. Suzhou Bojie Resin Technology Co., Ltd. provides ion exchange resin recycling wastewater copper, ion exchange with separation selectivity. The water purification effect is good. The advantages of high concentration multiple and environmental friendliness have attracted much attention in copper-containing wastewater treatment and copper resource recovery.
