The results show that the degradation effectiveness of PVA was optimum when potassium ferrate and sodium hypochlorite were jointly used as the oxidative agent. The removal rate of PVA and COD was more than 98% and 40% under the conditions that the concentration of PVA was 3.0 g/L and the pH value was 7.2, the dosage of potassium ferrate and sodium hypo chlorite were 0.32 g/L and 3.92 g/L, and the reaction time was 50 min. In the process of united oxidative degradation, the chain of PVA was cut off and many low molecular weight compounds were formed. The main degradation products were carboxyl compounds.

结果表明，用高铁酸钾与次氯酸钠联合氧化PVA时，降解效果最佳；在3.0 g/L，pH值为7.2的PVA溶液中，当高铁酸钾与次氯酸钠的投加量分别为0.32 g/L、3.92 g/L，反应时间为50 min时，PVA的去除率大于98%，COD去除率大于40%；在联合氧化降解过程中，PVA断链成小分子物质，最终降解产物主要为羧基化合物。

In the dynamic experiment of wet air oxidation of phenol with pelletized Ru/ZrO2-CeO2, phenol and COD reduction was maintained at 96% during 110 h of reaction. The concentration of the main intermediates was small. In the experiment of catalytic wet air oxidation of phenol, the leaching concentration of active species was small. There were small amounts of carbonaceous deposits on the surface of the used catalysts, and the carbonaceous deposits can be completely oxidized at 300℃.

在110h的催化湿式氧化苯酚反应中，苯酚和COD的去除率维持在96%左右，反应过程中活性组分的溶出浓度很小，催化剂表面有少量的积炭，但积炭在300℃能够被完全氧化。
