摘　　要：本文应用化学沉淀法、絮凝法和转化法对黄金矿山碱性含砷废水进行了试验研究.结果表明,采用氧化钙加絮凝剂或磷酸化学沉淀法、三氯化铁絮凝法、硫化亚铁转化法等处理碱性含砷废水,可使含砷废水达到工业废水排放标准0.5mg/L以下.Such harness was tested with chemical precipitation, flocculation and transformation. The experimental result is clear that the chemical precipitation method with calcium oxide plus flocculant or calcium oxide plus phosphoric acid, the flocculation method with iron trichloride, and the transformation method with ferrous sulfide all are favourable and featured. They reach down below 0.5mg/L of industrial drainage standard of wastewater. Their technological requirements are simple, and the supply of these chemicals is ample. As for cost, the method of iron trichloride laid lowest.
