A NOVEL SYMBIOTIC-BIOREACTOR FOR TREATING ODOROUS COMPOUNDS IN WASTE GAS EMISSIONS

摘要

In this study, a symbiotic microbial consortium, which consists of Lactobacillus spp., Actinomycetes, Rhodopseudomonas spp.; Saccharomyces spp.; and Chrysophyta, was applied for treatment of odorous volatile organic compounds (VOCs) and hydrogen sulphide (H_2S) from waste gas streams. The microbial consortium was seeded in a lab-scale bio-trickling reactor that packed with coal slag and fire expanded clay pellet. The results showed that this system was effective in treating a mixture of odorous contaminants (VOCs and H_2S) simultaneously. High removal efficiencies were attained for both VOCs ( > 99%) and H_2S ( > 98.5%). The bioreactor also showed long term stability, no clogging or aging problems of the packing medium were encountered, indicating a good potential for industrial scale up.
