| Abstract: | This experiment studied the treatment of fruit green dye wastewater by chemical coagulants.The dosages of coagulants FeSO4·7H2O and Fe（NO3）3·9H2O,and the pH value of the wastewater on the removal rate of COD and color were discussed.Studies showed that the removal rates of COD and color first increased and then decreased with the increases of both of the two coagulants.When the optimum dosage of FeSO4·7H2O was 0.9g/l,the removal rate of COD and color were 77.5%和88.2%,respectively;When the optimum dosage of Fe（NO3）3·9H2O was 0.02g/l,the removal rate of COD and color were 72.5%和93.2%,respectively.For FeSO4·7H2O,while the optimum pH value was 8,the decolorization rate could reach 85.1% and COD removal efficiency was 78.8%;For Fe（NO3）3·9H2O,while the optimum pH value was 8,the decolorization rate could reach 92.7% and COD removal efficiency was 77.8%. |
