Abstract

Abstract:

Studies of enhanced coagulation on the treatment of the Beidu raw water with low temperature and turbidity in Ningbo by selected coagulants and intensity of agitation are reported.The performances of polyalu-minum chloride,aluminum sulfate,polyferric sulfate and two kinds of commercial coagulants in the turbidity removal are compared by jar test.

摘要：

报道了对低温低浊的宁波北渡水进行强化混凝处理时,混凝剂及混凝搅拌条件的优化选择过程及结果。通过混凝烧杯实验,比较了聚合氯化铝、硫酸铝、聚合硫酸铁、两种市售药剂对该水的混凝脱浊效果,同时考察了强弱两种混凝搅拌条件对混凝效果的影响。
