摘要
六氯苯(HCB)既是持久性有机污染物,又是环境内分泌干扰物,在自然环境下HCB极难生物降解、光降解或化学分解。本文介绍了HCB的基本性质,总结了Fenton法、光催化氧化法和γ辐照氧化法等高级氧化法以及电动力学还原法、零价金属还原法等还原法降解HCB的基本原理、去除效率、影响因素等,对氧化还原法降解废水中六氯苯的发展方向和应用前景进行了展望。
Hexaehlorobenzene （HCB） is not only a persistent organic pollutant but also a environmental endocrine interferent; therefore, it can hardly be degradated by microorganisms, photo or chemical method in environment. The basic principles, removal efficiency and affecting factors of HCB degradated by advanced oxidation processes such as Fenton＇ s agent, photo - catalytic oxidation, γ irradiation and reduction processes such as electro - reduction, zero - valent metal reduction are analyzed. In addition, the development and application of HCB removed from waste water by oxidation and reduction process are forecasted.
