摘　　要：概述了目前先进氧化工艺产生羟基的方法.指出强电离放电能把H2O、O2加工成高浓度羟基、水合电子等自由基,具有工程意义,解决了先进氧化工艺应用上的一些难点.先进氧化工艺是从源头上解决污染物的生成问题,不使用对生态环境有害、有毒的原料、溶剂和催化剂,不产生有毒、有害的产物、副产品,实现了对环境的零污染.This paper summarizes the present methods of generating hydroxyl radical in AOTs, and pointes out that high concentration of hydroxyl radical, aqueous electron and other free radicals can be obtained with H_2O and O_2 by strong-ionization discharge. It is a new and feasible method to produce these free radicals on the level of engineering,and can overcame the obstacles limiting the application of AOTs. Advanced Oxidation Technologies (AOTs) have the advantages of avoiding the generation of pollutants, reducing the use of hazardous, toxic and environment-unfriendly materials, solvent and catalyst, and minimizing the production of wastes and byproduct from very beginning, therefore, zero Pollution to the environment is realized.
