【Abstract】 The wastewater treatment of Sn Pb alloy electroplating and polishing passivation of brass were harsh, owing to the complex composition, diversity of harmful substances, and fluctuant concentrations of the ingredients to be removed. Thus the titled wastewater after diffluence and well mixing was treated making use of physical chemical and biochemical combination treating processes. At the same time, an automation controlling system integrated with pH/ORP control and compute control was also applied for the treatment of the wastewater. It was found that the discharged water after the treatment met the relevant standard requirement and the process was satisfactory in terms of the industrial running.更多还原
