To compare with other industrial wastewater, the high contents of chromium, nickel and other heavy metal ions and cyanide makes electroplating wastewater is difficult to be treated. Different methods were used to treat wastewater according to their compositions because of the complex quality, high content of metal ions and uncontrollability of composition. Then decontaminate duct when the quality of discharged wastewater are better than national standard. The design of operation cost 14268.8 yuan pear day, covering area of 2504m2, treatment cost 2.575yuan per cubic meter. Keywords: electroplating wastewater;Wastewater treatment;sorting treatment II
