With the development of economy, living standard of citizens have been improved, the purification treatment of air pollution becomes more and more important. The volatile organic pollutants, VOCs, have great harm to human health and the environment. Biological filtration tower as typical processing tools have lots advantages like simple operation, low cost of operation and the little secondary pollution etc. In the practical application, the stability of long-term operation has problem, and it serious impact on the disposal effect and operation cost. Microbial proliferation excess in the tower lead to the filler layer congestion. It is a major cause of filtration column unstable operation. Therefore, in this article, through the research on the formation of regularity proliferation and jams of microbial in filtration tower. Established the multiplication rule model to simulate the changing process of microorganism concentration under different environmental conditions. Inspected the influence of toluene removal performance, packing layer drop pressure and void fraction, carbon balance and biomass growth after dosing ozone concentration and eluent NaOH in biological filtration tower.
