CALPUFF모델을 이용한 소각시설 배출가스의 시․공간적 영향 예측

Abstract

This study is carried out to predict the temporal and spatial variation of emission from new municipal solid waste incineration facility (MSW facility) by using the CALPUFF model. It can be seen that the contributing concentration at each receptor point was relatively low although the MSW facility is operating with the present Korean Emission Standard. As a result of modelling, the maximum contributing concentration is 0.665 ppb of NO2 and 0.19 ㎍/㎥ of PM10. It can be concluded that the effect of flue gas from new MSW facility on its surroundings is insignificant because of the low contributing concentrations of air pollutants emitted from New MSW facility. The dispersive types of flue gas from New MSW facility can be classified into four categories on the north-eastern part of Jeju Island, that is, winter type (Jan., Feb., Nov., and Dec.), spring type (Mar. ~ May), summer type (Jul. and Aug.) and Fall type(Sep., Oct., and Jun.). This is due to that CALPUFF model well reflects the wind change according to variation of time. However, the results of modelling in this study were not considered the wet deposition of air pollutants by the rainfall.
