摘　　要：报道了用超声波降解苯胺的试验 ,探讨了超声波辐射时间、溶液中苯胺的初始浓度、溶液温度、pH等因素对苯胺降解效果的影响。试验表明 ,超声波辐射的较适时间为 8min ,苯胺的较适浓度为 15 33mg/L ,适宜降解的培养条件为 ,温度 30℃ ,pH 7.5 ,培养时间 12d。此条件下的苯胺最高降解率可达 94 .2 %。A test for degradating low concentration aniline with ultrasonic wave by Phanerochaete chrysosporium is introduced.The effect of irradiation time was explored.The results show that the optimum growth pH and temperature of the fungus were 7.5 and 30℃,the optimum value of aniline is 1533mg/L,the highest removal rates of aniline were 94.2% after being cultived for 12 days by this condition.;
