摘　　要：研究了高铁酸钾同时去除微污染水中苯酚和Cr(Ⅵ).利用静态试验,分析了去除效果的影响因素,并初步探讨了其降解机理.结果表明,高铁酸钾氧化-絮凝协同去除Cr(Ⅵ)、苯酚和CODMn在氧化pH值为4.0,氧化时间20min,絮凝pH值为7.0,絮凝时间30min,高铁酸钾与苯酚的质量比为10:1的最佳条件下,Cr(Ⅵ)、苯酚、CODMn的去除率分别达到84.41%、28.33%、23.34%.说明高铁酸钾是一种可高效去除微污染水中Cr(Ⅵ)的水处理剂.The simultaneous degradation effect of phenol and Cr（VI） in the micro-polluted water by static method was studied. And the influential elements on the removal effects and probed into the degradation mechanism was analyzed. The results indicated that the removal rates of Cr（VI）, phenol, CODMn by synergetic effect of potassium ferrate oxidation and coagulation were 84.41%, 28.33%, 23.34%, respectively ,when the optimizing conditions were as follows： oxidation pH was 4,oxidation time was 20rain, flocculation pH was 7, flocculation time was 30min and quality ratio of potassium ferrate to phenol was 10：1. It showed that potassium ferrate was a water treatment agent which could degrade Cr （VI） effectively in the micro-polluted water.
