摘要
采用超声协同高铁酸钾法氧化降解苯酚废水,对比了单独使用高铁酸钾氧化降解苯酚废水。结果表明,超声协同高铁酸钾法氧化降解苯酚废水的效果好于单高铁酸钾法。在相同高铁酸钾投加量的条件下,苯酚去除率多30%以上,且超声协同高铁酸钾对废水溶液pH值的兼容性较高,在pH值为6~9范围内,苯酚去除率均达到86%以上。超声协同高铁酸钾法氧化降解苯酚废水的最佳反应条件是:高铁酸钾投加量1.0 g/L,废水溶液pH值为8,反应时间为50 min,苯酚去除率为89.8%。
The degradation of phenol wastewater by ultrasound synergistic potassium ferrate was compared with that by potassium ferrate alone.The results showed that the effect of ultrasound synergistic potassium ferrate oxidation degradation of phenol wastewater was better than that of single potassium ferrate method.Under the same dosage of potassium ferrate,the phenol removal rate was more than 30%,and the compatibility of ultrasound synergistic potassium ferrate to the pH value of wastewater solution was high,in the range of pH value 6~9,the phenol removal rate reached more than 86%.Under the condition that the ultrasound synergistic potassium ferrate oxidation treatment for the phenol wastewater the optimal reaction conditions were as follows:when the dosage of potassium ferrate was 1.0 g/L,the pH value of wastewater solution was 8,the reaction time was 50 min,and the phenol removal rate was 89.8%.
