Abstract: 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 Be²⁺ and Cu²⁺ 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.

摘要： 采用PAC和PAM对铍铜生产线污水进行沉降后，再通过斜板澄清器动态去除铍和铜。结果表明，在pH为9.0的情况下，以200~250 L/h流量投入PAC，PAC投加量为50 mg/L，再以150~200 L/h流量投入PAM，PAM投加量为2 mg/L，处理后的污水以30 m³/h流量通过斜板澄清器，再通过连续过滤装置，可一次性同时去除铍铜生产线污水中Be²⁺和Cu²⁺。该方法处理后污水中的Be²⁺<5 μg/L、Cu²⁺<2 mg/L，符合GB 8978—1996《污水综合排放标准》排放要求。
