| 摘 要： | 萃取法等传统分离方法在处理含铅稀水溶液时，效果较差；膜分离等新型技术存在膜中毒和再生等技术问题对采用沉淀气浮法去除水中的微量铅(含铅10mg／L)进行了研究，讨论了各种因素对去除率的影响，实验结果表明在表面活性剂质量浓度为20mg/L，铝铅摩尔比为3：1，pH值为9～10时处理效果较好，去除率可达97％。

| Abstract: | When the extraction and some traditional separating methods separate the lead ion from waste water , the coefficient of expulsion is small. The film poisoning and resuming exist a technical question in the film separation,. This paper studied the coefficient of expulsion which uses floats preconcentration method to separate the lead ion in waste water , and discussed the different factors affecting the coefficient of expulsion. The results show that on condition that pH is 9-10 , the gas liquid ratio is 3 to 1, the mole ratio of aluminium to lead is 3:1, the concentration of LAS(dodecybenzene sulfonic acid sodium salt) is 10 mg/L , and the coefficient of expulsion of the waste water in which lead ion concentration is 10?mg/L may reach 97% . |
