Abstract:

According to quality of the raw water,the optimal dosage of aluminium sulfate is studied on different turbidity and it is pointed out that a small quantity of PAM as coagulant aid can avoid increasing concentration of colloid again.At the same time,optimal dosage of coagulant is also analysed theoretically and its mathematics model that could explain the optimal dosage curve in the process of the experiment is set up.

Key words: turbidity, coagulating sedimentation, optimal dosage of coagulant

摘要：

根据水厂的原水水质情况,研究了不同原水浊度的硫酸铝最佳投量,并指出投加少量PAM作助凝剂,可避免胶体再稳现象的发生,同时也对混凝剂最佳投量进行了理论分析,建立了混凝剂用量的数学模型,该模型较好地解释了实验中最佳投量曲线的问题。
