subject: Metal Plating Wastewater Treatment Technology Overview And Outlook [print this page] Evaporation method is electroplating waste water evaporation, so that can concentrate heavy metals in wastewater and recycling of way, the generally applicable to the handling of chromium, copper, silver, nickel and other heavy metals in wastewater containing heavy metal ion concentration low water, the direct application of vaporization of law energy consumption, high cost, evaporation of heavy metal wastewater treatment and other methods and is generally used, such as atmospheric pressure Evaporator Combined with the current wash system using treated wastewater, can achieve closed loop, a good effect, evaporation of metal plating wastewater treatment, process maturity is simple, does not require chemical reagents, no secondary pollution, water or valuable metal back , good Environment Effectiveness and economic efficiency, but energy consumption, high operating costs, interfere with recycling issues that impurities to be studied, so that application is limited, at present, generally as a means of other methods of secondary treatment.
