Purification of waste air containing phenol vapors in biotrickling filter
Biotrickling filter is a kind of effective equipment used for purifying waste gases, its performance is affected by many factors. This research aimed at investigating the biodegradation of phenol contaminated-air streams in biotrickling filter. The effects of various experimental parameters such as solution pH, empty bed contact time(EBCT), initial phenol concentration and micro-organisms for de-phenol were investigated.Upon rapid start up operation, inlet phenol concentrations of up to 570mg/m3 did not significantly affect the performance of the biotrickling filter at EBCT of 65s, so that removal efficiency was well greater than 98%.In addition, the EBCT as low as 33s did not have detrimental effects on the efficiency of the bioreactor and phenol removal was greater than 98%. Decreasing the EBCT to 13s reduced the removal efficiency to around 90%. Microbiology tends to sepration and express as bamboo -like, fusiform and many other forms. Filamentous micelle belong to jersey algae, is a kind of highly efficient degradation of phenol bacteria.
