Abstract

This study was aimed at providing optimal water treatment processes based on various required water quality for utilization of the Saemangeum lake water as water supply alternatives to this area. Various water treatment methods were considered for investigation there characteristics, pollution removal rate, pros and cons in order to select appropriate water treatment processes satisfying the required water quality for different purposes. As results, the FDA system for SS, turbidity, BOD removals, UV treatment for coliform, BOD removals, FNR process for T-N, T-P removals, and ECRS process for desalination purpose were found to be better methods in senses of removal efficiency, operation and maintenance. Case studies were provided with cost analysis for field applications in the Saemangeum area.

새만금 지역의 담수수자원의 활용과 고부가가치 창출을 위해 새만금 담수호를 활용한 요구수질별 용수공급을 위한 최적의 수처리 시스템을 선정하고 이에 대한 비용분석을 통해 요구수질별 담수수자원의 활용방안을 제시하고자 하였다. 다양한 수처리 기법들의 종류, 주요 특성 및 오염인자 제거효율, 공법의 장단점 등의 비교분석을 통해 수질오염인자별 유리한 처리공법을 제시하였으며, 최적의 수처리시스템을 도출하여 새만금 지역 내 요구수질별 수처리 비용을 분석하였다. 연구결과를 통해 SS(Suspended Solid), BOD(Biochemical Oxygen Demand), 탁도 제거를 위해 FDA(Filter Disinfection Adsorption)여과기, 대장균 제거를 위한 UV(Ultra-Violet)처리공정, T-P(Total Phosphorus), T-N(Total Nitrogen) 제거를 위한 FNR(Ferrous Nutrient Removal)공법, 그리고 저농도 염처리 공정을 위해 전기투석법이 유리한 공법으로 조사되어 최적의 수처리시스템의 요소기술로 각각 선정되었다. 각 요구수질별 선정된 수처리공정에 따른 비용분석과 적용사례를 제시하여 새만금지역 담수 활용도를 높이고 부족한 상수원 해결의 대안으로 적용할 수 있을 것으로 사료된다.
