According to the characteristics of the quality and quantity of nickel-containing electroplating wastewater in a hygienic bath company in Hangzhou,the wastewater has been treated by the integrated treatment process,multi-medium pre-filtering+resin ion exchange. The project operating practice shows that when the quantity of the wastewa-ter to be treated is 6.5 m3/h,and the nickel mass concentration of the influent 100-150 mg/L,the filtration velocity of multi-medium filter 8.3 m/h,and the total residence time of ion exchange 37 min,the treated effluent nickel mass concentration is≤0.5 mg/L,turbidity≤1.0 NTU,electrical conductivity≤100μS/cm,meeting the limit value re-quirement of the Discharge Standard of Electroplatng Pollutants(GB 21900—2008). This project has the advantages of stable treatment effect and obvious environment benefit.
