Biological purification of exhaust air containing toluene vapor in a filter-bed reactor

摘要

Experiments during a period of 93 days are reported on the treatment of waste air containing toluene vapor using a laboratory scale biofilter system packed with peat inoculated with specific florae (Pseudomonas type) and intermittent- ly humidified with a nutrient solution necessary for the survival of the micro-organisms. Design and operation parame- ters were regularly measured in order to check the performance of the biodegradation process.
