The incineration process has commonly used for wastes amount reduction and thermal treatments of pollutants as the technologies accumulated. However, the process is getting negative public images owing to matter of hazardous pollutants emission. Specially dioxins became a main issue and is mostly emitted from municipal solid wastes incineration. In this reason, pyrolysis/gasfication/melting process is presented as a alternative of incineration process. The pyrolysis/gasfication/melting process, a novel technology, is middle of verification of commercial plant and development of technologies in Korea. But the survey about the pollutant emission from the process, and background data in these facilities is necessary. So in this survey, it Is investigated that the behavior of dioxins in three pyrolysis/gasfication/melting plant (S, T, P) of pilot scale. In case of S plant, concentration of dioxins shows high at latter part of cogenerated boiler and stack which are operate on low temperature conditions than a latter parts of pyrolysis and melting furnace which are operate on high temperature condition. Concentration of gas phage dioxins had increased after combusted gas passed cogenerated boiler and this is attributed to react of precursor materials such as chlorobenzene and chlorophenol. Concentration of dioxins in T plant showed lower levels at latter part of cooling equipment which are operate with water spray type on low temperature conditions than a latter parts of gasfied melting furnace which are operate on high temperature condition. Removal efficiency of dioxins at gas treatment equipment was 78.8 %. Concentration of dioxins in P plant was low at latter part of SDA/BF which is operate at low temperature conditions than a latter parts of pyrolysis gasfied chamber which are operate at high temperature condition. Removal efficiency of dioxins of SDA/BF was 85.9 % and therefore, it showed high efficiency at those of stoker type incineration facility. However, concentration of dioxins which emitted at high temperature condition were low in three facilities and satisfied present standard emission level of dioxins. To consider the distribution ratio of dioxins, Particulate phase dioxins at S and P plants showed similar ratio with which shows in current stoker type for middle scale domestic waste incineration facility. It is necessary to continuos monitoring the ratio of distribution of dioxins in T plant in because ratio of gas phage dioxins showed high.

2000년 6월 한달 동안 수도권매립지에서 발생하는 악취물질 농도를, 토양을 기준으로 삼차원 시뮬레이션이 가능한 예측 대기 오염 모델 TAPM를 이용하여 예측하였다. 수도권매립지 제1공구의 중앙부에서 0.7~1.5km 떨어진 지역에서 NH<sub>3</sub> 의 시간별, 월별 최대치는 각각 852.0ppb, 227.3ppb 로, H<sub>2</sub>S 는 8l.4ppb, 22.2ppb 로 예측되었다. 모델링 지역(50 × 50㎢)의 월별 평균농도는 NH<sub>3</sub> 3.91ppb, H<sub>2</sub>S 0.4ppb로 예측되었다. The concentrations of offensive odor substances have been predicted over Sudokwon Landfill area by a prognostic air pollution model (TAPM) with a terrain-following vertical coordinate for three-dimensional simulations during 1-30 June 2000. The hourly and monthly maximum value are predicted by 852.0ppb and 227.3ppb for NH<sub>3</sub>, 81.4ppb and 22.2ppb for H<sub>2</sub>S in where is about 0.7~1.5km away from the center of Landfill No.1 in Sudokwon Landfill area. The monthly averaged concentrations over modeling area(50 × 50㎢) are predicted by 3.91ppb for NH<sub>3</sub>, 0.4ppb for H<sub>2</sub>S.
