低浊度矿井水再利用的实验研究

Research on reuse of low turbidity mine water

针对低浊度矿井水的特点,采用试验方法,选用无机高分子絮凝剂聚合硫酸铁、聚合氯化铝与有机高分子絮凝剂聚丙烯酰胺复配使用,实验研究絮凝剂对矿井水浊度去除效果。通过正交混凝实验,研究了混凝药剂的投加量、混合转速、混合时间、反应转速及反应时间对混凝效果的影响,确定了处理矿井水的最佳混凝药剂及投药量及最佳水力条件。

According to the characteristics of low turbidity of mine water,the experiments research was carried out on the effects of the turbidity mine water removal of coagulant that is combined by inorganic polyferric sulfate,polyaluminum chloride and organic polyacrylamide.The treatment was studied by orthogonal test of coagulation settling.Influencing coagulant result of coagulator doses,mixed speed,mixed time,reaction speed and reaction time were investigated.The problems was solved about choosing the optimal coagulator,throwing doses and optimal hydraulic conditions.
