微纳米纤维离子交换树脂消除废水中重金属的应用研究进展

Research Progress of Application of Micro-nano Fiber Ion Exchange Resin in Eliminating Heavy Metals in Wastewater

电镀废水中重金属会对水体造成污染,且通过各种方式威胁着人类的身体健康,因此研发新型的重金属处理方法,回收电镀废水中的重金属离子对资源回收有着至关重要的作用。针对我国离子交换技术相对落后、以及传统重金属废水处理方法不能实现源头处理的问题,以电镀重金属污染废水为研究对象,将基于复合同轴流动聚焦原理的微纳米液滴雾化技术和离子交换技术进行有效整合和集成创新,开发出一种新型微纳米纤维离子交换树脂用于水中重金属污染治理,实现重金属离子的回收并实现源头治理的目的。

Heavy metals in electroplating wastewater will pollute water bodies and threaten human health in various ways.Therefore,the development of new heavy metal treatment methods and the recovery of heavy metal ions in electroplating wastewater have a crucial role in resource recovery.Aiming at the problem that China's ion exchange technology is relatively backward and the traditional heavy metal wastewater treatment method cannot achieve source treatment,the micro-nano droplet atomization technology and ion exchange technology are effectively integrated and integrated innovation to develop a new type of micro-nano fiber ion exchange resin to achieve the recovery of heavy metal ions and to achieve the purpose of source control.
