Odor Abatement in Biotrickling Filters for Wastewater Treatment Plants in Petrochemical Industries: Determination of Main Components of VOCs and Assessment of REs

Abstract:

A biotrickling filter has been set up in WWTP of Nanjing petrochemical factory for about 6 months. The purpose of this project was to assess the ability of the biotrickling filter to remove hardly biodegradable VOCs such as benzene, toluene, ethylbenzene and xylene which are recalcitrant and poorly water soluble and commonly found in petrochemical factories. PUF cubes (1 cm3) were used as the packing media treated with large amounts of circulating mineral salt medium added with bacterial species which came from secondary sedimentation tank of WWTP of Nanjing petrochemical industry. The controlled empty bed retention time (EBRT) of 90 s was a key parameter for reaching a removal efficiency of 91.7 %, 88.3 %, 70.7 % and 63.5 % for toluene, ethylbenzene, benzene and xylene, respectively. The analysis of the bacterial community in the BTF during VOC removal showed that Pseudomonas putida and Klebsiella sp. phylum were dominant microbes.
