유역하수도 공공하수처리시설의 방류수 수질 준수농도 설정방안 연구: 진위천 수계를 중심으로

다국어 초록 (Multilingual Abstract)

In accordance with the Watershed Sewer System Maintenance Plan enforced on February 2, 2013, the different compliance concentration of effluent limit be applied to effluent discharged from public sewage treatment works(PSTWs) in each watershed on the basis of water quality thereof. With the introduction of watershed sewer system, it is necessary to set the compliance concentration of effluent limit for PSTWs situated in the watershed, by region and PSTW size, to achieve water quality criteria for regional watersheds or target water quality under TMDL program. Watershed Environmental Agencies establish the Watershed Sewer System Maintenance Plan and set the compliance concentrations of effluent limit for PSTWs under the plan. The agencies plan to apply tougher effluent BOD concentration limits in Class Ⅰ to Ⅳ areas. Effluent BOD concentration limits will be toughened from 5~10 mg/L to 3 mg/L in class Ⅱ~Ⅲ areas, from 10mg/L to 5mg/L in class Ⅳ areas. Uniform application of effluent BOD concentration limits to PSTWs in the watershed sewer system need to be complemented considering type of sewage treatment technology employed and watershed characteristics. Therefore, this study presents method to determine the compliance concentration of effluent limit from PSTWs in the watershed.
