The Wastewater Project of a Certain Electroplating Enterprise in Jiangsu Has Successfully Completed Installation and Entered Commissioning

The heavy metal wastewater treatment project undertaken by our company for a certain electroplating enterprise in Jiangsu has successfully entered the stages of water simulation commissioning and actual wastewater commissioning. The company specializes in the research and development of surface electroplating of various materials, special new materials, and environmentally friendly electroplating processes. It mainly undertakes electroplating processing services in the fields of automobiles, aviation, aerospace, nuclear power, etc. During the electroplating process, the company generates various heavy metal wastewater with a water volume of 3000m ³/d. The wastewater mainly includes nickel, copper, chromium, zinc, etc., and most heavy metals exist in complex form. After being treated by physical and chemical methods such as breaking the network and precipitation, the copper, chromium, and zinc in the effluent can meet the relevant discharge requirements. However, nickel still has a concentration of 0.8-2.0mg/L and requires deep treatment to ensure compliance with discharge standards (nickel<0.1mg/L).

Our company adopts a self-developed special deep nickel removal adsorbent based on the characteristics and treatment requirements of this type of wastewater, which can achieve deep removal of nickel, including a small amount of ionic nickel in the total drainage, as well as complexed nickel that has not been treated before through breaking and precipitation (including breaking and precipitation). It has a high concentration ratio, good mechanical strength, and minimal loss during use. At the same level of ion strength, nickel ions are preferentially adsorbed, maximizing the resin's adsorption capacity for nickel. Therefore, the regeneration cycle is longer, the operating cost is lower, and it has a higher cost-effectiveness. At present, the nickel content in the effluent of the industrial plant on site is 0.01-0.09mg/L, which can stably meet the customer's contract requirements.
