蓄电池生产废水处理技术研究

针对蓄电池生产废水的特点，主要是含有浓度较高的氟化物和重金属铅类，同时含有一定量的有机物质和悬浮物，主要处理方法为物理化学方法。粉煤灰处理含氟水、石灰-硫酸-铁盐法、聚合硫酸铁和氢氧化钙以及聚丙烯酰胺联合处理含氟废水等处理方法都具有较高的除氟率。处理废水中重金属铅离子，目前工业中一般采用化学沉淀法和离子交换法。采用pH调节-石灰-铝盐反应沉淀工艺去除废水中的氟、铅及部分磷酸盐，采用生化处理去除有机物。

Research on Battery Production Wastewater Treatment Technology

Focusing on the feature of battery production wastewater, including mainly contains high concentration fluoride and heavy metals like lead, contains certain amount of organic matter and suspended solids, physical and chemical methods were mainly adopted to treat this kind of wastewater. Methods such as fly ash to deal with fluorinated water, lime and ferrous sulfate, combining polymeric ferric sulfate, calcium hydroxide and polyacrylamide together to deal with fluoride-containing wastewater, all achieve high fluorine removal rate. At present, chemical precipitation and ion exchange technique are generally adopted in the industt~y to remove heavy metal lead ions in the waster water. The technique of pH adjustment-lime-aluminum salt reactive precipitation was adopted to remove the fluorine, lead and part of phosphate in the wastewater, and organic compounds removed by biochemical treatment.
