초록

국내 하수처리장의 증가 및 방류수 수질기준 강화 등에 따라 하수 슬러지의 발생량은 지속적으로 증가하는 추세이다. 기존 하수 슬러지는 소각과 해양배출 등으로 처리하였지만, 대기오염과 해양배출 금지 등에 따라 최근에는 자원화 또는 에너지화 방법 등을 연구하고 있다. 그러나 전반적인 기술의 수준 및 적용기술에 대한 체계적인 분석 등이 부족하여 관련 기술에 대한 향후 분석이 필요한 실정이다. 본 논문은 슬러지 처리기술, 고체연료화 및 바이오가스 증산 활용기술을 대상으로 관련 특허, 논문 동향을 조사하였다. 또한, 국내 외 연구개발 추이를 분야별 5개 국가별(한국, 일본, 중국, 미국, 유럽)로 조사 및 분석하였다. 향후 슬러지의 효과적 처리를 위해 필요한 기술 분야를 제시하였다.

As the increase of domestic sewage treatment plant and reinforcement of the standard of effluent water quality continues, the volumes of sewage sludge are consistently increasing. Existing treatment of sewage sludge, such as incineration and ocean dumping has been prohibited because of air pollution and prohibitions towards ocean dumping, and in turn, recycling and energy recovery from waste methods have being studied recently. However, the lack of technical level and systematic analyses of application technique are problems, that future analysis of such relative technique would be required. The present study has been investigated as follows, management technique of sludge, patent on refuse-derived fuel and increase biogas production and utilizable technology, trend of research paper. Furthermore, research development from five developed nations (Korea, Japan, China, United States, and United Kingdom), domestic and foreign have been investigated and analyzed by section. In this study, the future technical field which is required for effective management of sludge has been suggested.
