A study on the characteristic of organic wastewater treatment in biofilm reactor with five types of media

생물막법에서 여재의 종류에 따른 유기성 오수의 처리 특성에 관한 연구

Recently, biofilm reactors are considered as efficient wastewater treatment system in rural areas, because of characteristics of easy operation and economic feasibility. In order to select the most efficient media, an experimental apparatus with five different media was designed, installed and examined. The media used in this study were zeolite, artificial sponge gourd, absorbent biofilter, non-woven fabric and charcoal. With only one month investigation, all five media showed high removal efficiencies of BOD.
