A Study on Composition of Municipal Solid Wastes and Characteristics of Leachate in In-Cheon Sanitary Landifil Site

인천시 위생매립지 쓰레기 조성 및 침출수 특성에 관한 연구

This study was performed to investigate the seasonal variation of the composition of domestic solid wastes and the characteristics of the leachate sampled in In-Cheon sanitary landfill site. The results were as follows 1. Combustible part was larger than incombustible part of the domestic solid wastes in spring and sumer. 2. The food waste was major source of solid wastes in In-Cheon city as 36.5%, and its variation by seasons was negligible. 3. BOD of the leachate was in the range of 853~7, 350mg/l, and fluctuated by seasons. 4. The mean of COD$_{cr}$ Was 5, 044mg/l, the mean of COD$_{Mn}$ was 2, 212mg/l. Namely, the method by $K_{2}Cr_{2}O_{7}$ was more sensitive than the method by KMnO$_{4}$. 5. TOC was in the range of 773~3, 958mg/l, it was lower than BOD.
