| 摘 要： | 采用聚合氯化铝铁(PAFC)对低温低浊海水进行混凝烧杯试验。结果表明,在海水水温低于10℃、浊度低于50 NTU时,PAFC的最佳投药量为15 mg/L,此条件下浊度、CODMn及UV254的去除率分别达到91.57%,54.47%和32.56%。通过试验比较了PAFC和聚合氯化铝(PAC)对低温低浊海水的混凝效果,得出PAFC的混凝效果优于PAC。

| Abstract: | The coagulation jar test was conducted for treating low temperature and low turbidity seawater by polymeric aluminum ferric chloride （PAFC）. The results showed that the optimal chemical dosage was 15 mg/L when seawater temperature was below 10℃ and turbidity was below 50 NTU, and the removal rates of turbidity, CODM, and UV254 reached 91.57% ,54.47% and 32.56% respectively under this condition. The coagulation of PAFC and polyaluminum chloride （PAC） on low temperature and low turbidity seawater was compared by test, and the coagulation effect of PAFC was superior to PAC. |
