摘　　要：对壳聚糖-活化硅酸处理低温低浊度水进行了初步的探讨,考察了壳聚糖-活化硅酸的用量、pH、壳聚糖分子量等因素对处理效果的影响,找到了最佳的工艺条件.试验结果表明,在原水浊度为8～10 NTU,水温为5～10℃的条件下,当活化硅酸投加量为2 mL/L,壳聚糖投加量为1.2 mg/L时,出水浊度可达到0.54 NTU.Treatment of low temperature and low turbidity water with chitin-active silica acid was discussed.Factors influencing treatment effect,such as dosage of chitin-active silica acid,pH and molecular weight of chitin were investigated,and optimal process condition was selected.The results showed that effluent turbidity was 0.54 NTU when the dosage of active silica acid and chitin were 2 mL/L and 1.2 mg/L respectively at the condition of 8~10 NTU for raw water turbidity and 5~10℃ for temperature.
