초록

본 연구는 UV, O_3, 촉매로 이루어진 물 재이용 시스템을 연구하였고 본 시스템 실플랜트를 제작하여 실험을 실시하였다. 이 시스템은 하이브리드 방식으로 막기술과 산화과정을 조합하였으며 폐수종말처리장 유출수에 적용한 결과 저비용 고효율의 효과를 얻을 수 있었다. 대상폐수의 성상과재이용 하고자 하는 양에 따라 UV와 O_3량 등을 변경 가능토록 설계되었으며 8주동안 본 시스템을 운전한 결과 SS, BOD_5, COD_(Cr), COD_(Mn), T-N, T-P, 색도의 처리효율은 각각 92, 92, 90, 90,70, 63, 90%를 보였고 총대장균과 일반세균은 모두 제거되었다. 환경부의 용도별 하수처리수 재이용 수질권고기준의 공업용수기준을 충분히 만족하고 있어 본 시스템이 산업폐수의 재이용을 위한폐수 재이용 처리시스템으로 충분히 활용 가능하다는 결론을 얻었다. 추가적으로 본시스템으로 잘처리가 되지 않은 인 혼합물의 처리를 위한 연구가 필요할 것이다.

In this study, the water reuse system consisting of UV, O_3, and catalyst was developed and its performance was evaluated using a pilot plant in the treatment of the discharged water from the existing water treatment plant. Our system adopted the hybrid system, the combination of membrane technology and advance oxidation process, which results in low operation cost and high efficiency in the treatment of wastewater. The unique feature of our process is that the system was designed to easily adjust the operational conditions such as the amount of feeding UV and O_3 based on the quaility of target water. During the operation of pilot plant for 8 weeks, the average removal efficiencies for SS, BOD_5, COD_(Cr), COD_(Mn), T-N, T-P, and color were investigated to be 92, 92, 90, 90, 70, 63 and 90%, respectively. No bacteria were detected during the operation of the pilot plant. Consequently the quality of treated water was satisfied with the standard for water reuse issued by Ministry of Environment of Korea. It means that the treated water from our water process could be re-supplied as industrial water. The results obtained from our lab and pilot scale experiments showed sufficient evidence to prove that the treated wastewater from our system was good enough to be reused for the purpose of industrial water supply usage. More researches are necessary in the future to treat phosphoric compounds which were not effectively treated in out process.
