摘要
采用扩散渗析技术对高铜含砷废水进行了铜砷分离,研究了静置时间、进水酸度、水流速、料流速和水流速与料流速之比对铜砷分离的影响。研究结果表明,静置时间为2h,进水酸度为5g/L,水流速为450mL/h,料流速为400mL/h,水流速与料流速的比值为450/400时,铜、砷综合分离效果最好。铜的分离率为92.65%,砷的分离率为50.21%。
Using diffusion dialysis technology to separate copper and arsenic from wastewater with high copper and arsenic, and made some studies on the ratio which standing time, influent acidity, the water flow velocity, the material flow velocity to the ratio of water flow velocity and material flow velocity to ratio of separation of copper and arsenic. Study shows that standing time of 2h, inlet water acidity of 5 g/L, water flow rate of 450 ml/h, material flow rate of 400 ml/h, the water velocity and the ratio of information flow for the 450/400, the total ratio of separation is best. The separation ratio of copper is 92.65% and the arsenic is 50.21%.
