Electroplating wastewater discharge standards for the electroplating enterprises water and air pollutants emission limits, monitoring and control requirements. To promote regional economic and development, promote the adjustment and transformation of economic growth mode of economic structure, guide the development of electroplating production process and pollution control technology, wood standard specifies the water pollutant discharge limit opening electroplating enterprises in particular odor pollutants emission, Environmental Noise of appropriate national emission standards, resulting in the identification of fluid waste treatment and disposal applicable national solid waste pollution control standards. Since the implementation of the mouth of this standard, electroplating enterprises water and air emission control executed in wood standards, not executed "Integrated Wastewater Discharge Standard" (GB8978-1996) and "Air Pollutant Emission Standards" (GB16297- the relevant provisions of 1996) in. Electroplating is the use of chemical and electrochemical methods of metal or other material coated on the surface of various metals. Plating technology is widely used machine building, light industry, electronics and other industries. Electroplating wastewater composition is very complex, in addition to cyanide (CN-) waste water and acid waste, heavy metals electroplating wastewater is potentially extremely hazardous wastewater categories. Heavy metals contained in waste water according to the classification of heavy metals in general can be divided into chromium (Cr) wastewater containing nickel (Ni) wastewater containing pot (Cd) of wastewater containing copper (Cu) water, zinc (Zn) water, gold (Au) wastewater containing silver (Ag) wastewater. Treatment of electroplating wastewater widespread attention at home and abroad, developed a variety of control technology, non-toxic treatment by poisonous and harmful into harmless, recovery of precious metals, water recycling and other measures to eliminate and reduce emissions of heavy metals. With the increasing rapid development of electroplating industry and the environmental requirements, at present, electroplating wastewater treatment has begun to enter the clean production technology, total control and integration phase of circular economy, resource recycling and closed loop is the main directions of development.
