Abstract:

Arsenic contamination of water and associated health risks have been reported in many regions of China. Leaching of arsenic from industrial wastewater into groundwater may cause severe contamination, which requires proper treatment before its emission. Therefore, sulfur dioxide reduction combined diffusion dialysis method is adopted to dispose the wastewater containing high concentration of copper and arsenic. Effects of the sulfur dioxide reduction process of the flow of sulfur dioxide, reaction time, reaction temperature and stirring speed and the diffusion dialysis process of the influent acidity, water flow velocity and material flow velocity on the ratio of separation of arsenic and copper were studied in this paper. The results show that on the conditions of the flow of sulfur dioxide of 3 kg/h, reaction time of 1h, at room temperature, stirring speed of 800 r/min and influent acidity of 5 g/L, water flow velocity of 400 ml/h, material flow velocity of 400 ml/h, the integrated effect of separation is best. The separation ratio of copper reaches 94.71 % and that of arsenic is up to 95.63 %.
