【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,对原水浊度小于等于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。更多还原

【Abstract】 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.更多还原
