高盐高铁酸性矿井水处理研究

根据高盐、高铁酸性矿井水的水质特点,提出了中和-曝气-混凝沉淀-锰砂过滤-精密过滤-反渗透-消毒的联合处理工艺,试验确定了工艺中的有关参数.试验结果表明,该净化技术特别适合于高盐、高铁酸性矿井水的处理,处理后的出水水质稳定,浊度小于0.30 NTU,硫酸盐浓度为8 mg/L,溶解总固体为33 mg/L,总硬度为(CaCO3)15 mg/L,氟化物浓度为0.2 mg/L,氯化物浓度为6 mg/L,铁的浓度小于0.01 mg/L,锰浓度小于0.01 mg/L,每百毫升总大肠杆菌个数及细菌总数为零,完全满足国家饮用水标准.

Research on treatment of acid mine water with high salty and high iron

According to the water features of the high salty and high iron acid mine water,the paper provided the combined treatment technology with a neutralization,aeration,coagulated setting,manganese sand precision sand filtration,reverse osmosis and disinfection. The test had set the related parameters of the technique.The test results showed that the purification technology was especially suitable for the treatment of the high salty,high iron content acid mine water.The water quality of the outlet after the trea...
