Peat-Based toluene biofiltration: a new approach to the control of nutrients and pH

摘要

This paper describes an eighty days toluene vapour removal from air by a peat-based biofilter to study the effects of different inocula and nutrient supplies on the biofiltration efficiency. Four pure microbial strains were used for the inoculation of the biofilter matrix: i. e. Arthrobacter paraffineus, from the American Type Culture Collection (ATCC) and a further three aromatic hydrocarbons degraders selected from among those in private collections. The toluene inlet load was maintained at constant value throughout the trial. To improve toluene biofiltration, changes in the inoculation of the filter bed have been diversified.
