초록

본 연구는 환경부 시범사업으로 진행된 수원시 물 재이용(중수도)시설물 설치사업으로 설치된 물재이용시설을 통하여 건축물 단위의 물재이용을 통한 물 부족 문제 해결 가능성을 살펴보았다. 개별 건축물 단위의 물재이용이 이루어지며 도시의 물 수요를 최대 25%까지 줄일 수 있다. 이는 우리나라의 수자원 부족 문제를 해결할 수 있는 수준이다. 하지만 개별 건축물 단위의 물 재이용 시설을 활성화하려면 사용자의 중수도 거부감 해소와 경제성 문제를 해결하여야 한다. 중수도 거부감 해소는 MBR 공정과 AOP 공정을 연계 하였을 경우 해결 가능하다. MBR 공정과 AOP 공정을 연계하여 운영할 시 사용자들은 상수도와 중수도의 수질 차이를 느끼지 못하는 것으로 나타났다. 경제성 문제는 건설비와 운영비를 고려할 경우 시설용량 100톤/일 이상, 운영비만 고려할 경우 15톤/일 이상일 경우 상 하수도요금 수준에서 해결이 가능하다. 더 나아가 사회적 편익비용까지 고려할 시 150톤/일 이상부터는 수익이 창출되는 것으로 나타났다.

This study examined the possibility of solving the water shortage problem through the water reuse of buildings through the Suwon water reuse (greywater) facility installation project conducted as a pilot project of Ministry of Environment. Water reuse of individual building units can reduce city water demand by up to 25%. This is a level that can solve the water shortage problem in Korea. However, in order to revitalize the water reuse facilities of individual buildings, it is necessary to solve the problem of the user's rejection of the greywater and the economical problems. The resolution of the user's rejection can be solved by linking the MBR process with the AOP process. When the MBR process and the AOP process are operated in conjunction with each other, it is found that the users do not feel the water quality difference with the tap water. Economical problems can be solved at the water rate levels when the facility capacity is over 100 ton/day considering the construction cost and the operation cost, and when the operation cost alone is over 15 ton/day. Furthermore, when considering the social benefit cost, it is found that profit is generated from 150 ton/day.
