%X 研究了以粉煤灰和盐酸酸洗废液为原料制备混凝剂的方法,确定酸浸反应的最佳的工艺条件为温度80℃,反应时间2h,盐酸浓度4mol/L。聚合氯化铝铁混凝剂最佳优化条件为在碱化度为2,n(Fe)/n(A l)为1∶1。混凝剂在投加量为30mg/L(有效含量),pH为6.5~8.0之间时,浊度去除率达91.86%,在同等条件下PAFC明显优于PFC、PAC。 To study the mothod of with the fly ash and hydrochloric acid pickling waste water as raw materials to prepare coagulant polyaluminum chloride(PAFC),determine the best operation condition of acid diping process for the temperature of 80 ℃,reaction time 2 h,hydrochloric acid concentration of 4 mol / L.PAFC coagulant the best optimum conditions for the basicity is 2,n(Fe)/n(Al) is 1:1.coagulant of the dosage to 30 mg / L(effective content),pH to between 6.5～8.0,turbidity removal rate reached 91.86 percent,under the same conditions PAFC is superior to PFC,PAC
