摘　　要：介绍甘肃某黄金冶炼含砷废水处理工艺流程及设备配置情况。该冶炼厂含砷难处理金精矿来自多个矿山,原料成分复杂,制酸净化工段产生的废水含铜、铅、砷等杂质。采用硫化沉淀与石灰—铁盐法联合工艺处理含砷废水,处理后排水可达到GB8978—1996《污水综合排放标准》中的一级指标,废水可全部循环利用。The flowsheet and equipment configuration of arsenic wastewater treatment system for a gold smelter in Gansu are described. As the refractory gold concentrates with arsenic from multiple mines, the composition of the raw materials is complex, so the wastewater from the purification section contains copper, lead, arsenic and other impurities. The technological procedures applied sulfide precipitation process combined with lime-iron salt process is designed to treat the arsenic wastewater. The drainage is consonant with the first grade indexes of GB 8978-1996 《integrated Wastewater Discharge Standard》 and all wastewater is recycled.
