摘　　要：根据高浊矿井水的水质特性,进行了矿井水的混凝实验研究.分别采用聚合氯化铝、三氯化铁及复合铝铁盐三种混凝剂进行烧杯实验,确定最佳混凝剂,通过正交实验确定最佳水力条件,同时确定了对最佳GT值的影响因素.结果表明,复合铝铁盐的混凝效果最佳,最佳投药量为16 mg/L;最佳水力条件为:混合G值256.5 s-1,GT值15 390;反应G值7.7 s-1,GT值6 930;投药量对最优GT值有较大影响,随着投药量的增加,最优GT值减小.Based on the characteristics of high turbidity mine water quality, the coagulation experiment was carried out. PAC, Fecl3 and PAFC were used to ascertain the best coagulant. By orthogonal experiment,the best t hydrodynamic condition was ascertained. Meanwhile, influencing factor of the best GT was ascertained. The result shows that the PAFC has optimum coagulation effects and its best dosage is 16 mg/L;the best hydrodynamic condition： the mixed G is 56.5 s^-1 ,the mixed GT is 10 170;the reactive G is 7.9 s^-1 ,the reactive GT is 17 280. Chemical feed quantities have very big influence on the best GT. With increase of chemical feed quantities, the best GT will decrease.
