摘　　要：以聚合氯化铝（ＰＡＣ）为混凝剂，通过静水沉淀实验，以澄清水层的残余浊度为指标，以原水浊度小于等于４００度的常规矿井水的混凝最优ＧＴ值进行了研究，认为原水浊度４００度，水温１７￣１９℃ＰＡＣ投加量２０ｍｇ／Ｌ时最优ＧＴ值为４．２×１０＾４，原水浊度１００时最优ＧＴ值为２．３×１０＾４，可供生产设计参考。Aluminium polychloride is used as a coagulant. By means of the method of stalic tests of settling this paper takes the residual turbidity of clarified water as an index to study the best coagula-tive GT value of common mine water, Which' s turbidity is equal to or less than 400 degrees. It is regarded that the best GT value is 4.2×104 while raw water' s turbidity is 400 degrees, temperature 17 - 19℃, PAC's adding 20 mg/L; the best GT value is 2. 3×104 when raw water' s turbidity is 100 degrees. All above can be consulted in design of production.
