초록

2017년 기준 서울시 및 광역시의 하수도 보급률은 90% 이상의 높은 하수도 보급률을 보이며, 국내하수처리장의 개소 수는 2010년 3,064개에서 2017년 기준 4,072개로 약 25% 증가 증가하였다. 그중에서도 SBR계열 공법으로 운영 중인 하수처리장은 현재 585개로 2010년 대비 17% 증가한 것으로 나타났다. 상수원의 수질 개선과 소규모하수도 시설의 운영개선을 위해 안동 임하댐 권역 내 하수처리장 500㎥/일 이상 3개소 및 500㎥/일 미만 46개소, 총 49개소 시설을 대상으로 모델링을 적용하여 공정개선방안을 연구하였다. 모델링을 위한 개선안으로 5년간 운영자료 등을 검토하여 후보군을 도출하였다. 49개소의 시설은 총 12가지 종류의 공법으로 운영되고 있으며, 이 중에서 SBR공법의 500㎥/일 이상 시설 1개소와 500㎥/일 미만의 46개소를 3개 유형으로 그룹 분류를 하여 운영 개선이 가능한 9개소를 선정하였다. 500㎥/일 이상 1개소에 모델링를 적용한 결과, SRT 조절을 통해 방류수 수질 개선이 가능했으며, 소규모 처리장 9개소에 적용한 결과 총 인의 제거율을 최대 14.4% 개선할 수 있는 것으로 나타났다. 이에 본 연구의 결과자료는 공공 하수처리시설 및 마을 하수도 시설에 대한 개선 및 운영 개선 방안으로 활용될 수 있을 것으로 판단된다.

As of 2017, the sewerage penetration rate of Seoul and metropolitan cities is more than 90%, and the number of domestic sewage treatment plants increased by 25% from 3,064 in 2010 to 4,072 in 2017. Among them, sewage treatment plant operated by SBR system is 585, which is 17% higher than 2010. In order to improve the water quality of the water source and improve the operation of the small sewage facilities, the improvement of the process was studied by applying the modelling to 49 facilities of the sewage treatment plant in Andong Imha dam area with more than 500㎥/day 3 places and 46 places less than 500㎥/day. As an improvement plan for modelling, candidate data were derived by reviewing operation data for 5 years. 49 facilities are operated by 12 types of operating processes. Among them, 1 place mort than 500㎥/day with SBR method and 9 facilities with less than 500㎥/day were selected by dividing 46 sites into 3 types. As a result of applying modelling to more than 500㎥/day, it was possible to improve the quality of discharged water through SRT control and it was found that applying model to sites of small scale treatment plants can improve the removal efficiency of TP by up to 14.4%. As a result, the data of this study could be used to improve and improve the operation of sewage treatment plants and RCSTP(Rural Community Sewage Tratment Plant).
