环境持久性有机污染物治理技术进展

Progress in treatment technology for environmental persistent organic pollutants

介绍了持久性有机污染物(POPs)的特征和分类,综述了近年来POPs的降解方法,包括物理法、化学法和生物法。物理法仅将POPs进行转移,基本上都是配合其他方法使用;化学法能够将有机污染物彻底分解、矿化,具有设备简单、操作简便、反应快速、高效、对后续的生化处理没有毒害作用等优点,成为了近年来水处理领域的研究热点;生物法主要包括微生物、植物、动物修复技术,生物法设备简单、效果较好,使用很广泛。

The characteristics and classification of persistent organic pollutants(POPs)are introduced,and the degradation methods for POPs in recent years are reviewed,including physical,chemical and biological methods.Physical methods can only change the form and location of POPs.Compared with other methods,chemical method is the most popular one in recent years because of its some exciting advantages such as decomposing completely and mineralizing organic pollutants,innocuousness,simple operation and rapid degradation and mineralization.Biological method mainly include microbial,plant and animal remediation technologies,meanwhile,it needs simple experimental installation,can reach conspicuous effect and widespread application.
