A simple and convenient detecting means of HO · radicals and Dimentsionally Stable Anodes,made by ourselves with special technology,are employed in this study. The results show that a great deal of OH·radicals,with very high oxidation ability,can be produced during electrolysis. They can oxide the organic pollutants in the wastewater, i.e.the pollutants are degraded in an indirect way,which is the main mechanism of electrolysis catalysis oxidation technology. Because of mentioned above,the electrolysis catalysis oxidation technology is one of AOT.%采用简便易行的方法对用形稳阳极电解处理有机废水的机理进行了研究，表明在电解过程中能够产生氧化能力极强的HO·自由基，可以氧化降解废水中的有机污染物，即有机污染物以间接氧化的方式降解，这是电解催化氧化技术的主要机理。由于上述原因，电解催化氧化技术也属于高级氧化技术的范畴。
