하수처리수 재이용을 위한 카본블럭 여과시스템의 최적운전조건 도출 = Deduction of Optimum Operating Condition of Carbon Block Filtration System for Wastewater Reuse

국문 초록 (Abstract)

국내 재이용수는 대부분 하천유지용수에 집중되고 있으며 신도시의 확대에 따라 도시재이용수로의 이용증대가 요구되는 시점에서 하수처리수 재이용수 용도별 수질기준 만족을 위한 최적 3차 처리기술 확보가 필요한 시점이다. 본 연구는 하수처리수 재이용과 처리수 수질개선을 위하여 카본블럭을 이용한 여과 공정을 연계한 시스템 구성을 통해 입자제거 가능성을 평가하는데 목적이 있다. 카본블럭의 수처리 특성을 알아보기 위해 수평형 카본블럭 수처리 모듈로 처리장치를 구성하였다. 실험 결과, 역세공정을 미적용하여 지속적으로 운전할 경우 플럭스는 여과시간에 따라 지속적으로 감소하는 것으로 나타났다. 또한 카본블럭의 여과저항 특성을 살펴보면 플럭스가 감소함에 따라 여과저항은 0.01에서 0.07까지 증가함을 알 수 있다.

Domestic reclaimed water is mainly concentrated on river management flow and as new towns are expanding gradually, the usage enlargement toward city reclaimed water is really needed at this stage and securement of the best 3rd process technology is also needed for the satisfaction of water quality standard by use of wastewater as reclaimed water. The aims of this research are focused on wastewater reuse and evaluating the possibility of particle removal through organizing system linked to filtration process using carbon block for the improvement of effluent quality. To examine the characteristics of water treatment of carbon block, we composed processing installation with horizontal carbon block water treatment module. As a result of experiment, in case of constant operation without backwash process it was approved that flux was decreased continuously according to filtration time. And also when focusing on the characteristic of filtration resistance of carbon block, it was approved that the filtration of resistance increased from 0.01 to 0.07 as flux decreased.
