Research advances in microbial ecology of biofilter and biotrickling filter for waste gases treatment
废气处理生物滤器微生物生态学研究进展

Waste gases biofiltration is an emerging technology,and has played important roles in air pollution control.In this paper,the structure of biofilter and biotrickling filter and their mechanisms in air pollution removal were introduced,with focus on the research advances in the isolation and identification of microbes in the filters,correlations between microbial abundance,activity and community diversity,influences of operation conditions on microbial community,spatiotemporal change patterns of microbial community structure during operation,development of biofilm,and biodegrading dynamic models.The research perspectives in microbial ecology during biofiltration of waste gases were discussed.
