摘要
采用火焰原子吸收法对大同市"5.18"左云新井煤矿透水事故中所排酸性废水及其应急处理外排水中铁锰进行跟踪测定。结果表明,在废水处理过程中加入石灰石中和,脱铁脱锰,pH均值7.9,总铁浓度均值1.07mg/L,均达到污水综合排放标准。
Flame atom absorption luminosity method was used to detect Fe - Mn from water inrush accident of Zuoyunxin coal mine. The results show that limestone is used to remove Fe - Mn, the pH value is 7.9, the concentration of total ferric reaches 1.07 mg/l, all the indexes can reach national discharge standard.
