摘要
结合有色金属废水水质特点,根据化学、混凝和助凝沉淀原理,采用组合絮凝、助凝沉淀手段,对钼浮选矿废水进行了深度处理试验研究,尾矿库沉降处理后的选矿废水能达到《污水综合排放标准》(GB8978-1996)一级排放指标,完全满足选矿回水水质要求,可实现回水循环利用。
Combined with the features of wastewater in nonferrous metals processing, based on principles of chemical, coagulation and aid sedimentation, adopted the ways of combined flocculation and aid sedimenta- tion, the deep treatment test is conducted for mining processing wastewater of molybdenum. It is showed that the mining processing wastewater of tailings reservoir after sedimentation treating can reaches the first - class discharge index of （（ Integrated wastewater discharge standard））（ GB8978 - 1996 ）and meets the quality re- quirement for mining processing recycle water, and the water can be circular utilized.
