缓释材料在有机污染地下水原位修复中的应用研究进展

Research Progress in Application of Slow-Release Materials in In-Situ Remediation of Organic Contaminated Groundwater

地下水有机污染的原位修复中常面临污染拖尾、反弹以及反向扩散等难题。缓释材料(SRM)可在长时间内缓慢释放活性物质,以维持原位修复作用的长期有效性,是应对此类问题的新方法。结合国内外相关研究,详细介绍了SRM的组成、制备方法及反应动力学,并对SRM在实验室及实际场地中对地下水有机污染的修复效果进行综述,最后对SRM的未来发展前景进行展望。

In-situ remediation of organic pollution in groundwater often faces challenges such as pollution tailing,rebound,and reverse diffusion.Sustained-release materials(SRM)can slowly release active substances over a long period of time to maintain the long-term effectiveness of in-situ repair,which is a new method to address such issues.Based on relevant research at home and abroad,the composition,preparation methods and reaction kinetics of SRM were introduced.The remediation effects of SRM on organic pollution in groundwater in laboratories and actual sites were also reviewed.Finally,the future development prospects of SRM were discussed.
