Design and operation adjustment of ventilation and deodorization system in an underground sewage treatment plant

Taking the reconstruction of a sewage treatment plant as the research object, through comparing the principles and characteristics of deodorization technologies such as chemical adsorption, combustion, biological filter and sheltering, the deodorization technology of “biological drip filtration plus biological filtration” is determined. Combined with the problems in operation adjustment, CFD technology is used to simulate and analyse the air distribution, and reasonable operating conditions are obtained to further optimize the deodorization system and ventilation system. Finally, the odor emission reaches the first-level standard of GB 18918-2002.
