Abstract

This research studied the bio-methane potential of several waste biomass materials as alternative sources for biogas production, and the laboratory procedure for measuring the biochemical methane potential was described. The wastes from four agro-industries (sewage, livestock, food wastewater treatment sludge and cattle rumen substance generating in slaughter house) were evaluated as substrates for the assay of biochemical methane potential. In order to estimate the ultimate methane yield, two empirical equations (modified Gompertz equation and exponential equation) was investigated. The ultimate methane yield of sewage, livestock, food sludge and lumen substance estimated by the modified Gompertz equation were 0.086, 0.147, 0.146, and 0.121 L $CH_{4}\;g^{-1}\;VS_{added}$, respectively. The ultimate methane yield estimated by the exponential equation were 0.109, 0.246 and 0.174 L $CH_{4}\;g^{-1}\;VS_{added}$ in sewage, livestock sludge and lumen substance. And the ultimate methane yield estimated by the exponential equation showed more high values in the range of 26.7 ~67.3% than the ultimate methane yield estimated by the modified Gompertz equation.

본 연구는 안성시 관내에서 발생하는 폐기물계 바이오매스 중 가축분뇨, 하수, 음식물 슬러지와 도축장에서 발생하는 소 반추위 잔재물을 실험에 공시하고 각 폐자원별 메탄생산퍼텐셜을 측정하였다. 또한 기존 연구자들이 메탄생산퍼텐셜을 측정 자료로부터 최대메탄생산량을 추정하는데 이용한 Modified Gompertz model과 Exponential model을 이용하여 최대메탄생산량을 추정에 있어 모델별 적용성을 비교 검토하고자 하였다. 하수, 가축분뇨, 음식물 슬러지 및 반추위 잔재물에서 TS 함량은 각각 18.1, 23.7, 13.6, 14.8%이었으며, VS 함량은 14.3, 18.9, 11.9, 12.5%이었다. 유기성 폐자원별로 혐기배양 전후 pH는 7.93~8.32의 범위에서 7.09~7.25로 약간 낮아졌으며, 배양기간 중 VS 분해율은 37.8, 8.3, 12.5, 56.4%이었다. Modified Gompertz model을 이용하여 구한 단위메탄생산량은 하수, 가축분뇨, 음식물, 반추위 잔재물에서 각각 0.086, 0.147, 0.146, 0.121 L $CH_{4}\;g^{-1}\;VS_{added}$이었으며, Exponential model을 이용하여 구한 단위메탄생산량은 하수, 가축분뇨, 반추위 잔재물에서 0.109, 0.246, 0.174 L $CH_{4}\;g^{-1}\;VS_{added}$로 Modified Gompertz model을 이용하여 추정한 단위메탄생산량과 비교하여 26.7 ~67.3% 정도 높게 추산되었다.
