摘　　要：以石化污泥为菌源,采用好氧振荡培养法对温度在30℃—60℃、浓度<52 mg.l-1的甲苯废气进行降解实验研究.结果表明:混合菌对甲苯的生化降解能力随甲苯浓度的增大而增大,随温度的升高而降低;降解效率则随浓度的增大而减小,随温度的升高也降低.逐渐升温对甲苯的降解性能优于直接升温.球状菌是降解高温甲苯的优势菌种.Based on the mixed culture from petrifaction sludge, biodegradation experiments of toluene waste gas which temperature is between 30℃ and 60℃, concentration is below 52mg · l^-1was carried in an aerobic swing-bed. The results showed that the eliminated capacity increased with the increasing of concentration of toluene, while decreased with the temperature＇ s increasing. The removal efficiency of toluene both increased with increasing of the temperature and the concentration. When the temperature is above or equals to 50℃, the biodegradation capacity by increasing the temperature day by day is superior to the course by increasing the temperature directly. Ball bacterium is the dominant bacterium that can degrade toluene at high temperature.
