Abstract—The objective of this study is to further evaluate the
relationship between removal effect of anic II. EXPERIMENTAL METHODS
pollutants (DOC) and their characteristics (biodegradability,
adsorbability and molecular size distribution) in different A. Pilot plants
running stage of BAC filter. The experimental results showed
that during early period of operation, BAC filter mainly removed Exhaust gas
adsorbable DOC (that is ADOC), but after continuously running
for five months, the main body to be removed by BAC filter was
adsorbable and biodegradable DOC (that is A&BDOC), and the BAC filter
distribution of molecular weight for this fraction of DOC was
3kD~1kD and <. Biological regeneration of BAC only can Ozone generator O3
keep its continuous removal efficiency for B&ADOC but can’t
remain that of NB&ADOC.
