| Abstract: | The industrial waste pyrite cinder,crystalline AlCl3,industrial water glass and industrial hydrochloric acid are used as raw materials to confect polysilicic acid aluminum ferric chloride (PSAFC).The PSAFC is then used as coagulant to treat printing and dyeing wastewater,with good purifying effects obtained.It is shown that the optimal conditions for treating printing and dyeing wastewater are under pH of 8～9 and basification degree( B ) of 1.The removal rate of CODCr can reach over 90%. |

| Keywords: | coagulant printing and dyeing wastewater basification degree ( B ) electrophoresis removal rate of COD Cr |
