摘要
近年来,聚合氯化铝在工业废水治理过程中应用逐渐广泛,但在有色金属选矿废水中砷及氟化物的治理案例较少,尤其是针对选矿废水中低浓度砷及氟化物的治理应用相对较少,本研究运用聚合氯化铝针对于选矿废水中的中低浓度砷及氟化物,通过实验室小试、工业试验,得出聚合氯化铝对低浓度有色金属选矿废水中砷及氟化物的治理效果显著,并通过连续运行跟踪,研究工艺的可行性、稳定性、经济性。
In recent years,polyaluminum chloride has been widely used in the treatment of industrial wastewater,but there are few treatment cases of arsenic and fluoride in non-ferrous metal mineral processing wastewater,especially in the treatment of low concentration arsenic and fluoride in mineral processing wastewater.In this study,polyaluminum chloride is used to treat middle and low concentration arsenic and fluoride in mineral processing wastewater.Through laboratory experiment and industrial test,it is concluded that the treatment effect of polyaluminum chloride on arsenic and fluoride in low concentration non-ferrous metal dressing wastewater is remarkable.
