摘　　要：研究了强化混凝处理低温低浊的水库水的混凝剂优化选择。通过烧杯试验比较了各混凝剂对低温低浊水的脱色除浊效果,结果表明,相对水厂用普通混凝剂,所选低温低浊专用混凝剂PAFC2及PAC2出水矾花密实、沉降速度快、成本低。The enhanced coagulation on the treatment of the reservoir raw water with low temperature and low turbidity by selected coagulants were studied.Through Jar test, the purification evaluation of turbidity and color were compared with various kinds of polyaluminum chloride, and the results indicate that the floc is more dense, setlled more quickly and low cost when coagulants PAFC2 and PAC are used to treat the raw water with low temperature and turbidity.
