中文摘要：

中国面临环境保护的重大压力，高级氧化技术（AOT）是解决环境污染的理想绿色技术，而高级氧化技术是指·OH制备以及诱发一系列的攻击污染物及微生物反应。从源头上解决了治理污染过程中再污染的问题。高级氧化技术规模制备·OH是其标志性核心关键问题。基于此，学术界进行了一系列羟基自由基制备研究工作。本文介绍了在水中制备·OH的方法，主要介绍O3/H2O2、OJUV、H2O2/EUV、Fenton、光催化氧化、电子辐射和水激励等方法；也介绍了在气体中制备·OH的方法。主要有脉冲电晕放电法、电子束和强电离放电法等。强电离放电法有望同时解决在水、气中规模制备·OH过程中存在的问题。

英文摘要：

China is facing the significant pressure of environmental protection; Advanced Oxidation Technology （AOT） is an ideal green technology that could well solve the problem involving environmental pollution. AOT refers to the preparation of hydroxyl （. OH） radicals, inducing a series of reactions with ·OH radicals that attacks pollutants and microorganism, therefore AOP is able to thoroughly solve the re-pollution problem in the process of pollution treatment at the source. Since the producing · OH radicals with a large scale is a key technology in the study of AOT, many scholars have done a series of studies on the · OH radicals preparation. The major methods of producing · OH radicals in water, including O3/H2O2, OJUV, H2O2/UV, Fenton, photocatalytic oxidation, electronic radiation, and water excited, are introduced. The methods of producing ·OH radicals method by air discharge, such as pulse corona, electron beam, and strong ionization discharge are also presented. The strong ionization discharge method could solve the problem producing · OH radicals with large scale in the water or in the gas.
