摘要：
"aged" biofilter media was adopted as the inoculum to accelerate the maturation of biofilter for iron and manganese removal in the start-up of filter column. morphology of "aged" biofilter media and new quartz sand was observed with SEM. The results indicate that the "aged" biofilter media coated by a large quantity of bacteria which reduces the start-up time to 30 daysand affords strong Mn-removal efficiency at the beginning of the process. This method probably can be used for the start-up of new filters when there are well-established biofilters around.
