چکیده انگلیسی
A fungal biotrickling filter (BTF) was employed to treat trichloroethylene (TCE) gas under different magnetic field intensities (MFIs). When the TCE inlet concentrations were approximately 370, 500-900, and 1000â¯mg/m3, the removal performances followed the order: MFI 20.0â¯mTâ¯>â¯MFI 60.0â¯mTâ¯>â¯MFI 80.0â¯mTâ¯>â¯MFI 0â¯mT. In particular, at a TCE inlet concentration of 1000â¯mg/m3, MFI 20.0â¯mT was significantly better than MFI 0â¯mT performance. The corresponding removal efficiencies and maximum elimination capacities were 52.9%, 4854.1â¯mg/m3â¯h and 39.4%, 3594.8â¯mg/m3â¯h, respectively. BTF was shut down completely for 7â¯days and rapidly recovered in 6-10â¯days. High-throughput sequencing indicated that MF significantly affected the fungal community and significantly improved the relative abundance of the phylum Ascomycota, achieving the highest abundance of Ascomycota at MFI 20.0. These results indicated that a lower MFI can efficiently improve TCE removal performance in a fungal BTF.
