에너지원으로 바이오가스에 대한 잠재적 가능성이 인식되면서 최근에 바이오가스의 생산기술을 제고하고 에너지 효율을 개선하기 위한 기술개발이 지속적으로 진행되고 있다. 본 논문의 목적은 혐기성 소화 과정에서 바이오가스 생산을 증가시키기 위한 효과적이고 효율적인 슬러지 전처리 방법에 대하여 분석하였다. 이를 위해 본 논문에서는 각각의 전처리 방법의 장점과 단점을 분석하여 바이오가스 생산에 미치는 영향요인을 비교·분석하였다.

The potential of using the biogas as energy source has long been widely recognised and current techniques are being developed to upgrade the technical quality and to enhance energy efficiency. The objective of this paper is to present efficient and effective pre-treatment methods of increasing the amount of produced biogas in anaerobic digestion of activated sludge treatment process. The paper also presents a review of the effect on biogas production between pre-treated and raw sludge, and also put forward the advantages and disadvantages of each pre-treatment method.
