SWMM을 이용한 공업지역에서의 비점오염원 관리 설계 기법

Abstract

Ministry of environment has introduced TMDL(Total Maximum Daily Load) for improving Han river’s water quality since 1998. TMDL is quite different to emission concentration regulation. TMDL is to establish target water quality and to control total pollutant loads. To implement TMDL made quality of water management plan to easily set. But quantification of Non-point pollutant is rearing its ugly head because rate of Non-point pollutant in the total pollutant into the river increases by urbanization. Accordingly National Institute of Environmental Research published The Technical Guideline of Water Pollutant Load Management. But there is problem to formulate water quality control initiative because urban of type of land use in The Technical Guideline of Water Pollutant Load Management was excessively calculated. Also there is not contents about TSS that occupy most of the pollutant. This study suggest technology guideline about TSS(Non-point pollutant) in industrial areas that is divided from urban and non-point pollutant sources management by using SWMM. This study use observed data at noksan · myeongji national industrial complex in Busan like research data. This research utilizes Matlab-SWMM automatic estimating parameters for improving to assume parameters and analyzes average annual reduction effect about TSS per design WQCB capacity(mm) by using removal efficiency equation of TSS of Non-point pollutant removal detention facility. When to set water quality plan of TMDL in industrial ares, it will be expected to be applied this study result.
