황산염을 이용한 매립지 유기물분해 촉진과 분해속도에 관한 연구 = The Study on Increase the Decomposition of Organics and Organic Removal Rates by using Sulfate in Sanitary Landfills

다국어 초록 (Multilingual Abstract)

In this study, sulfate reduction reaction was used to increase the decomposition of organics, which is the most critical factor for the stabilization of a landfill site. Composite of sewage sludge, papers, and incineration ashes was used in the column. The experimental results indicated that out of 10 reactors, the reactors 3, 4, 8, and 9 showed higher organics (i.e., TOC) removal rate than that in the absence of sulfate. The organics removal rates (K) in R3 and R9 were 8.65e^(-4)/d and 3.82e^(-4)/d, respectively. The times to reach 10% of initial concentrations in R3 and R9 was 7.3 and 16.5 years, respectively, showing faster organics decomposition rates in these reactors.
