영문 초록

An experimental investigation has been carried out to evaluate the characteristics in wastewater treatment using an anaerobic packed bed bioreactor with ceramics, rubber sponge, soft stone A, and soft stone B as carrier. The results of the work have shown that soft stone A as a carrier was superior to other carriers in methane production, then the content of methane for soft stone A was about 70%. First of all, soft stone A had higher efficiency of the COD removal than the others in response of passing the operation, as well as it had a low volatile acid in reactor. In addition, the slope of methane production with respect to the removal of COD ($m^{3}CH_{4}$/kgCOD) was 0.58 for soft stone A. In biomass hold-up equation for each carriers, the equation of soft stone A was m$_{p}$=714 ($C_{o}/0.41+C_{o}$) and it was the largest in this experimented carriers. Based upon the results obtained, it is suggested that the major effective carrier in wastewater treatments within the packed bed bioreactor used in this experimental work by soft stone A.
