초록
대도시의 인구집중과 환경문제에 대한 관심의 고조에 따른 환경배출기준의 강화로 환경처리시설에서 배출되는 슬러지의 양은 매년 급증하고 있는 실정이다. 2003년부터는 하수처리 슬러지의 매립지에의 직매립을 금지하고 있을 뿐만 아니라, 2012년부터는 해양투기 또한 전면 금지됨을 따라 육상에서의 자원화 혹은 감량화 등을 통한 소각, 퇴비화 등의 방법으로 처분해야 하는 실정이다. 그러나 이들 슬러지의 성상은 슬러지발생원, 발생 시기, 처리공정 등에 따라 그 성상이 다양하게 변하는 특성을 가지므로 슬러지처리, 재활용 및 처분방법을 결정하는데 있어서 슬러지성상에 대한 평가가 중요하게 작용한다. 이를 위하여 물리화학적 처리, 생물학적 처리 등 서로 다른 처리방법에 의해 발생되는 슬러지의 성상평가방법을 표준화할 필요성이 크다고 하겠다. 그러나 아직까지 우리나라에서는 표준화된 슬러지 성상평가방법이 제정되어 있지 않다. 본 총설에서는 우리나라의 슬러지 성상평가방법에 관한 현황과 문제점 등을 파악하고, 독일 등 선진국의 사례를 바탕으로 적절한 슬러지의 재활용과 처분을 위한 우리나라에 적합한 15가지 항목의 표준화된 슬러지 성상평가방법을 제시하고자 하였다.
As the interest in environmental problems increased, the guideline of effluent qualities becones strict and the amount of sludge produced from the wastewater treatment facilities steeply increased. The revised Korean acts prohibit the direct reclamation of the sludge exhausted in sewage treatment works from 2003, and the ocean dump of sludge will be also prohibited from 2012. Therefore, the sludge must be recycled, incinerated or composted. To properly perform the utilization and disposal operations the establishment of well-defined procedures for the characterization of sludge by physicl, chemical and biological method and setting up of guidelines for different treatment and disposal routes has become necessary. However, there have not been such standardized methods for sludge characterization in Korea. This review analyzes the present status of establishment and problems of sludge characterization method of Korea. Finally, it ws proposed total 15 items of standardized characterization methods suitable to our country for proper sludge recycling and disposal, which was based on the more systematic standard methods of Germany (DIN 38414) and those of advanced nations.
