受微污染湘江原水强化水处理工艺研究

采用强化混凝工艺、强化混凝与活性炭联用工艺对湘江微污染原水及低温低浊原水进行中试研究。结果表明，对于处理受微污染湘江原水，聚合氯化铝混凝效果最佳；处理湘江低温低浊原水时，聚合硫酸铁效果最佳：高产酸钾与粉末活性炭联用助凝，能有效地去除有机物；强化混凝与活性炭联用处理工艺能有效地去除湘江原水；有机物以及消毒副产物前体，还能增加活性炭吸附能力。

Study of Slightly Polluted Raw Water of Xiang River by Enhanced Water Treatment Technology

Treatment of Xiang river water with process of enhanced coagulation, composite processes of enhanced coagulation and activated carbon and treatment of Xiang River water of low turbidity under low temperature were introduced in this paper. The results showed the coagulant to treat the slightly polluted raw water of Xiang River with better purification effect is the PAC, the coagulant to treat water of low turbidity under low temperature is PFS, joint technique of using potassium permanganate and powdered activated carbon to aid coagulation can lower the pollution of organic matter availably, the composite processes of enhanced coagulation and activated carbon not only has a wonderful result of reduction in DBPFP and organics, but also improve the adsorption of activated carbon.
