        매립 연령에 따른 침출수 특성

        In order to investigate optimum process of leachate treatment depending on the landfill site age, anaerobic decomposition rate of organic matter and the change of ratio of humic and fulvic substances, distribution of organic matter after and before anaerobic degradation were studied. As the age of landfill site increases, it was observed that biodegradable organics were getting lower and the removal rate of dissolved organic carbon (DOC) under the anaerobic condition was decreased. It was found that over 50 % of the raw leachate was composed of high molecular weight organics (above M W. 10 K NMWL) and most of those were consisted of fulvic and humic acids. The older the landfill site is, the higher molecular weight of organic composition is. In the raw leachate. the fraction of fulvic was twice as much as that of humic acid. The removal efficiencies of fulvic and humic acids by anaerobic treatment were approximately 80 % and 20 %, respectively and which indicated that if humic acid were removed effectively, the leachate treatment efficiency could be improved.
