摘　　要：针对稀贵金属冶炼废水中重金属离子、砷含量高的特点,提出一段硫化、一段中和结合膜过滤的处理工艺。该工艺能够有效地处理富含Cu、Pb、As等元素的废水,处理后污水水质优良。具有工艺简单、投资省等优点。There were many precious metals. When dealing ions of heavy metals in the wastewater of the smelting of less common and with the wastewater, the process of first sulfurization was adopted then neutralization with the combination of filtration. Adopting this new process, better use of the wastewater full of Cu, Pb, As and etc. was made, and the quality of the water after dealing with was excellent. Additionally, the process had the advantages of simple operation and less investment.
