| 摘 要： | 针对高藻期原水的特点,采用复配混凝剂并进行烧杯试验对复配混凝荆方案进行了优化,结果表明,无论聚合氯化铝(PAC)与FeCl3复配还是聚合氯化铝铁(PAFC)与FeCl3复配,混凝反应后的沉淀出水浊度都明显低于单独投加FeCl3,并且pH值能稳定在7.5以上.在总投加量相同的情况下,先投PAFC或PAC再投FeCl3的投药顺序最优;PAFC和FeCl3复配投加的最佳质量比为3:1,PAC和FeCl3复配投加的最佳质量比为1:2;投加间隔时间为5～20 s.采用复配混凝剂的水处理成本至少低于单独投加三氯化铁30%.

| Abstract: | Combination of two kinds of coagulant was optimized by jar test according to the features of raw water in high algae period.The result showed that both dosing polyaluminum chloride(PAC) and ferric chloride(FeCl3),and dosing polyaluminum ferric chloride(PAFC) and FeCl3,the supernatant turbidity was obviously lower than merely adding FeCl3,and pH could be stably maintained over 7.5.Also,in condition of the same total dosage,the best dosing order was to add PAFC or PAC first and then FeCl3,and the best mass ra... |
