초록

세계적인 물부족을 해결하는 대안 중의 하나는 하수 재이용이다. 본 연구는 A시의 하수를 UF와 RO 공법으로 처리하여 인근지역의 공업용수로 재사용이 가능한지의 여부를 확인하고자 하였다. A시의 하수를 UF와 RO로 처리한 결과 Na, Mg, Cl, Ca, Mn, $PO_4$, $SO_4$ 등은 원수 대비 97% 이상의 높은 처리 효율을 보였으나, $NH_4$-N, TN, $NO_3$-N, BOD등의 영양염류는 각각 35.71%, 85.21%, 87.05% 그리고 56%로 상대적으로 낮은 제거율을 보였다. 그러나 영양염류는 원수 자체의 함유량이 소량 이여서 하수 처리수 공업용수 재이용수질 권고 기준을 만족하는데 문제가 없었다. 그 외의 측정항목 또한 하수 처리수 공업용수 재이용수질 권고 기준을 만족하여 인근지역의 공업용수로 재사용에는 문제가 없을 것으로 예상된다.

One of alternatives to solve the global water shortages is the reuse of wastewater. The aim of this study was to evaluate whether it can be reused for industrial water from wastewater in "A" City with ultrafiltration (UF) and reverse osmosis (RO) process. The results obtained in this study were that the inorganics such as Na, Mg, Cl, Ca, Mn, $PO_4$, $SO_4$, etc. were removed with high treatment efficiency (more than 97%), respectively. However, the removal of $NH_4$-N, TN, $NO_3$-N, BOD was found to be 35.71%, 85.21%, 87.05% and 56%, respectively. The removal efficiency of nutrients was relatively low compared to other metal ions. Despite low nutrients removal, the treated wastewater is recommended to reuse, because the nutrient contents in influent from the secondary wastewater treatment plant were small amount. In addition, all other metrics in the wastewater were found to be lower amount than wastewater reuse criteria. Therefore, the wastewater treated by UF-RO could be sufficient to reuse for industrial waster.
