Experimental results showed that the optimum condition of treating effluent was Fe2+/M2+ 10, dosage of additive 1.4g/L, M3+/M2+ 1.6, initial Zn2+/Cu2+ 33.3.The saturation magnetization of magnetic precipitate was 45.9 emu/g, and metal recovery was 85.0%.

• 经试验研究确定了处理该废水的工艺条件:Fe2+/M2+10；添加剂用量1.；4g/L；M3+/M2+1
