Abstract—Selection the stuffing and optimization its surface can preparation process such as: nanomodified ceramic [5],
increase the biological treatment system capacity and buffer modified polypropylene biofiller [6]. The other is to change the
capacity. Biological deodorizations of hydrogen sulfide (H2S) was surface properties such as: Foldesova [7] and others found
conducted by using modified ceramic which was made under through the thermochemical and physical methods to change
different density of modifying agent as carrier in biotrickling the surface properties of ceramic increases the metal
filter. All modified ceramic had strong abilities to immobilize adsorption. At present the relevant surface modifications of
deodorization bacteria and the biofilm time was four days. It was filler used to remove contaminants have less reporting.
found that the modified ceramic which was prepared under the
modifying agent was is better than other modified The performance of modified filler depends on
ceramics for its surface feature changes, more content of modification conditions. The modified condition
