电化学氧化技术去除废水中的持久性有机污染物

水体中存在的微量持久性有机污染物对人类及生物的正常生命活动构成了严重威胁，有效去除这些污染物已成为当务之急。一般的水处理技术很难奏效，随着新型掺杂半导体复合电极不断开发成功，通过电化学氧化技术有望在常温、常压下将之转化为无害的CO2与H2O等物质，并不对环境造成二次污染。本文对国内外电化学氧化技术在处理水体中持久性有机污染物方面的研究进行了阐述，介绍了电化学氧化原理及影响因素，对采用不同电极氧化持久性有机污染物效果进行了论述。

Removal of Persistent Organic Pollutants in Wastewater by Electrochemical Oxidation Technology

There are small amount of persistent organic pollutants existed in water systems,and this does great harm to human beings and biology. It is necessary to remove these materials immediately. However,it is no use for the common water treatment technologies. As some new semi-conductor electrodes doped with additives were prepared,the electrochemical oxidation technology may efficiently oxidize persistent organic pollutants into CO_2 and H_2O under normal temperature and pressure thoroughly,and there are no extra pollutions produced. In this article,the developments of electrochemical oxidation technology on treating persistent organic pollutants were discussed,meantime,the electrochemical oxidation mechanisms and all kinds of influential factors were introduced,and the emphasis was placed on the structures and properties of electrodes.
