Abstract
This study uses zinc sulfate heptahydrate (ZnSO4·7H2O) to configure zinc-containing electroplating wastewater as simulated wastewater, and uses polyaluminum chloride (PAC), ferric chloride hexahydrate (FeCl3·6H2O) and potassium aluminum sulfate dodecahydrate (KAl (SO4)2·12H2O) are three preferred coagulants. The optimal coagulant is analyzed by simulating the absorbance change of zinc-containing electroplating wastewater. The experimental results show that the three different types of coagulants have a certain treatment effect. The best dosage of coagulant is 15 mg/L, and the order of treatment effect is PAC>potassium aluminum sulfate>ferric chloride.
