Abstract:Biological purification with foam balls of 10 mm in diameter as microbial carrier is proposed for the treatment of waste gas from car wheel hub coating. Results from this work show stable and effective purification is achieved even under severe fluctuations in the composition and concentration of coating waste gas. The efficiency of waste gas removal varies with different pollutants, e.g. ≥70%, 61% and ≥90% for benzene, methyl isobutyl ketone, and butyl acetate, respecitvely. Therefore, this study demosntrates the potential of biochemical methods for the purification of waste gas in painting. Key words:painting workshop/ volatile organic compounds/ bio-filter/ removal rate/ site disposal.
