| Abstract: | A new process in which pickling waste liquor is used as raw material to make compound iron coagulating agent is introduced. The product can be used to dispose electroplating and dyeing wastewater .The application of project and experimental result show that when dealing with electroplating wastewater contained Ni 2+,Cu 2+ and Cr 6+,concentration of effluent are both below 0.1 mg/L for Ni 2+ and Cu 2+ ,Cr 6+ is not detected; It can also dispose several chemical plating liquid waste; For dyeing wastewater, the removal rate of COD and color are more than 84% and 98%,respectively. So this kind of coagulant should be further developed and spread. |
