Abstract:

The phenol in simulated wastewater has been treated with activated carbon fiber(ACF) and immobilized laccase,and characterized by means of SEM、FTIR、DSC and TG. The influences of different factors on the phenol removing effect are studied. The optimal technological parameters are determine as follows:the temperature is 50℃,and pH 4.0-7.0,the removing rate of phenol is still 63.4% after having been used for 7 times circularly. The removing effect is obviously better than that of ACF and laccase. By the ultrasonic synergy method,the treatment effect of phenol wastewater by immobilized laccase can be improved,and the maximum removing rate can reach 95.1%.

摘要：

采用活性炭纤维（ACF）固定化漆酶处理模拟废水中的苯酚，通过SEM、FTIR、DSC及TG表征，研究不同因素对苯酚去除效果的影响，确定了最佳工艺参数：最佳反应温度为50℃，最适pH为4.0~7.0，且循环使用7次后去除率仍有63.4%，去除效果明显好于ACF和漆酶。通过超声协同作用的方法，提高了固定化漆酶处理苯酚废水的效果，去除率最高能达到95.1%。
