离子交换技术在重金属废水处理中的应用

Application of Lon Exchange Technology in Heavy Metals Wastewater Treatment

重金属废水由于所含重金属对人类和环境的危害,需要对其进行处理。化学沉淀法被广泛应用于重金属废水的处理过程,但采用化学沉淀法处理重金属废水时,会产生大量的重金属污泥,需要妥善处理或处置。离子交换技术处理重金属废水,既可实现废水中重金属的去除,有可回收废水中的重金属,避免化学沉淀法处理重金属废水时产生大量的污泥。离子交换树脂对废水中重金属离子的选择性分离,可以更好的实现废水中重金属离子的处理和重金属离子的回收。

Heavy metal wastewater must be treated because the wastewater containing heavy metal ions harmed to human being and environment.The method of chemical precipitation was widely applied to treating the wastewater,but the mass sludge heavy metal produced with the method needed to be disposed properly.The wastewater was treated by ion exchange technology,heavy metal ions could be removed and could be recovered,and avoided much sediment from wastewater treated by chemic-Sedimentation.Heavy metals could be better...
