Abstract: A bioscrubber was used to treat waste gas laden with phenol.An average removal efficiency of 97% was achieved stably,while the average removal capacity was around 30 g/(m~3·h).It was found that if the mass loading was above 50 g/(m~3·h),phenol in liquid was to be accumulated,which could affect performance of the system.Further researches need to be conducted on how to cope with the situation of high mass loading of phenol.
