摘要
以硫酸铝[Al2(SO4)3]、硫酸铁[Fe2(SO4)3]、三氯化铁(FeCl3)、氯化铝(AlCl3)为混凝剂处理选矿废水,探讨了不同混凝剂的处理效果及三氯化铁处理砷、镉等离子的混凝机理。结果表明,用混凝工艺处理选矿废水效果显著,三氯化铁(FeCl3)为最佳混凝剂,最佳添加用量为16mg L,废水经处理后符合国家排放标准。
Treatment of metallurgy wastewater using Al2（SO4 ）3, Fe2 （SO4）3, FeCl3, AlCl3 as coagulants has been studied. The coagulation effects of different coagulants and the coagulation mechanism of FeCl3 for removing arsenic, cadmium ionic also have been discussed. And the experiment results show that FeCl3 is the best coagulant for treating mineral processing wastewater. When the addition of FeCl3 in treatment reaches 16 mg/L, the discharging water can meet the national standard.
