The dynamic removal of beryllium and copper element was achieved by slanting plate clarifier after the wastewater of beryllium copper production line was settled by PAC and PAM. When the pH of wastewater was 9.0, PAC with a mass concentration of 50 mg/L at a flow rate of 200-250 L/h and PAM with a mass concentration of 2 mg/L at a flow rate of 150-200 L/h were injected in the wastewater sequence, respectively. The treated wastewater flowed through the slanting plate clarifier at a flow rate of 30 m3/h and then filtered continuously through the filtration device. The results show that Be 2+ and Cu 2+ concentrations are lower than 5 μg/L and 2 mg/L, respectively, which complies with the Standards of GB 8978—1996. Therefore, the Be2+ and Cu2+ elements in the wastewater can be removed at the same time.
