| 摘 要： | 本文采用石灰——硫酸亚铁化学混凝沉淀法处理含铅、砷重选尾矿废水。探明了石灰、硫酸亚铁的加入量、PH值等因素对废水中铅和砷等有害物质去除率的影响和沉淀时间对悬浮物去除率的影响。废水经处理后,铅、砷和悬浮物含量均能达到排放标准。这是一种适用于钨锡矿山尾矿废水处理的经济、有效的方法。

| Abstract: | The treatment on gravitation separation tailings containing compounds of lead and arsenic by means of floculation and precipitation was described in this paper. The effect of various factors such as the amount added lime and ferrous sulfate, pH and settling time etc. on removal efficiency of the hazardous chemicals have been ascertained. After the treatment by this method, the amount of laed and arsenic contained in wastewater can accord with the discharge standard. Thus, this is an economical and effectual method suitable for tailing wastewater of tungsten and tin mine. |
