Nitrogen source and biomass removal effects on the performance of biotrickling filters packed with modified organisms suspended filler or volcanic rock during toluene removal

摘要

BACKGROUNDTwo identical biotrickling filters, BTF1 and BTF2, were loaded with modified organisms, suspended filler and volcanic rock. The start-up times of both biotrickling filters were compared, and their performances were evaluated in terms of removal efficiency and elimination capacity. The parameters influencing the removal performance, such as the nitrogen source and biomass removal, were investigated.
