The Physico chemical Characteristic of MSW and sludge in west area of Kangwondo

강원도 영서지역 생활폐기물 및 슬러지의 물리·화학적 특성에 관한 연구

In this study, the physico chemical characteristic of MSW and sludge in west area of Kangwondo was investigated for database, managing the waste and waste treatment facility. The sampling sites were selected as 6 different MSW generation area and 2 sludge generation area. it is necessary to measure the characteristics of MSW to build the data-base. The year of 2000, 197.4ton/day of MSW which was generated in this area. This MSW was composed of 26.6% food wastes, 24.2% of papers, 22.8% of plastics & vinyls, 9.6% of textiles, 3.80% of wood, 2.8% of rubbers & leathers and others, respectively. Most of MSW are composed of food, paper and plastic waste and combustible waste is more than 89%. The generation of papers and vinyls are almost same for different seasons For 3-components of MSW, moisture is 40.2%, combustible component is 52.1% and ash is 7.7% and for 3-components of sludge, moisture is 83.3%, combustible component is 7.7% and ash is 9%. The chemical element has the high order of carbon(51.6%), oxygen(38.6%), hydrogen(7%) on the dry basis of wastes. And the high heating value of MSW is 4989.4 Kcal/kg sludge is 4428.04 Kcal/kg and low heating value of the MSW which is measured by calorimeter is 2032.88kcal/kg. From the leaching test of wastes, there is no heavy metals.

본 연구에서는 강원 영서지역의 도시쓰레기와 슬러지의 물리 화학적 특성을 조사 연구 하였다. 도시 쓰레와 슬러지는 각각 6곳,2곳에서 샘플을 수거 분석하였다. 이 지역에서 2000년도에는 하루 197.4 톤의 폐기물이 발생하였다. 폐기물의 성분은 음식물 26.6%, 종이류 24.2%, 플라스틱 비닐류 22.8%, 섬유류 9.6%, 목재류 3.8%, 고무류 2.8% 등으로 이루어져 있다. 도시쓰레기의 3성분은 수분 40.2%, 가연분 52.1%, 불연분 7.7% 이며 슬러지 3성분은 수분 83.3%, 가연분 7.7%, 불연분 9% 이다. 화학 조성은 탄소류 51.6%, 산소 38.6%, 수소 7%로 이루어져 있다. 도시 쓰레기의 고위 발열량은 4989.4 kcal/kg 이며 슬러지의 발열량은 4428.04 kcal/kg 이다. 용출 실험에서 중금속 성분은 거의 발견되지 않았다.
