Some Electroplating Enterprise Wastewater Treatment Engineering Design And Application Research

Electroplating industry is one of the world three big industrial pollution, the produce of wastewater has a great toxicity and harmfulness, the wastewater has reached more than one over ten of the total industrial wastewater emissions but only less than half of the wastewater before discharge to get effective governance. At present, with the increasing expansion of electroplating enterprise, the resulting wastewater composition is also more and more complex, the difficulty of processing is more and more big, the water pollution problem has seriously restricted its own survival and development of electroplating enterprises in our country, therefore, the composite electroplating wastewater treatment technology and process research is necessary.This paper takes xi ’an some electroplating enterprise comprehensive electroplating wastewater as the research object, by studying the wastewater containing copper, nickel plating process wastewater and wastewater containing chromium waste water and complexing, based on the principle of diversion discharge, high quality processing for wastewater treatment. Heavy metal ion wastewater can be treated by chemical method, the use of high efficient precipitation separation technology and automatic control technology to make wastewater treatment more stable. According to the chemical properties of different wastewater processing respectively at the same time, can improve the quality of the water treatment to reduce drug consumption and processing costs of water treatment. Then use efficient precipitation separation technology to make wastewater discharging standard. Using box filter press sludge dewatering and cake sinotrans disposal of qualified units. Technical scheme USES the "integrated hydraulic clear water purifier" as the main processing equipment, ensure the effect of the physical and chemical reaction. Make the system reach the emission standard is guaranteed, based on the operational technical, economically feasible, and has great use value.
