| Abstract: | Electroplating wastewater of Datong Gear Factory contains not only CN -,but also Cr 6+ ,Zn 2+ ,and Cu 2+ .Facing the fact,a new chemical method was used to treat the wastewater.In the method,CN - was removed by oxidation at first,then Cr 6+ was removed by reduction and precipitation.All ion concentrations of the treatd wastewater were lower than those in the wastewater discharge standards of China. |
