Influencing Factors of Phenol Waste Gas Removal in Biotrickling Filter

Abstract:

Phenol waste gas was treated by biotickling filter. The results operated n a month showed that when phenol was between 50mg/m³ and 100 mg/m³, phenol removal efficiency was more than 94%. Phenol elimination capacity of the system was around 30mg/L h. The system had high resistance to shock loading. the phenol removal efficiency did not decreased with increasing influent loading rate when it was lower than 100mg.L^-1.h^-1. The gas to liquid ratio almost had no adverse effect on the phenol efficiency when the ratio was in range of 1.1 to 2.2m³/L. The removal loading rate increased with the increasing of recycling phenol concentration. When phenol concentration was lower than 1000mg/L, the biotrickling filter still run in high efficiency. The biofilm in first stage of filling materials removed 90% of influent phenol.
