Abstract

Customers water quality complaints by foreign substance in local water service can be able to call the main cause bring the distrust for tap water and inhibiting the rate of drinking water. In this study, foreign substances were collected in the target region. Foreign objects were subjected to qualitative and quantitative analysis of compounds and elements components to reveal the cause of detection. Also, resolve the complaints by foreign substance and improve the reliability for tap water providing high quality water supply scheme. Collected substances at the water quality complaint area were included in inorganic compounds due to internal corrosion and aging pipeline, as well as organic compounds containing a large amount of carbon (C) and oxygen (O) component. To decide and reduce for foreign substance, objective assessment of pipe condition in target area was required.

지방상수도에서 이물질에 의한 수질민원은 수돗물에 대한 불신을 초래하고 음용률을 저해하는 가장 큰 요인이라 할 수 있다. 본 연구에서는 수질민원 대상지역의 이물질 수집 및 시료의 정성 및 정량분석을 실시하여 이물질에 함유되어 있는 화합물과 원소성분을 검출함으로서 이물질 발생의 원인을 밝히고 해결방안을 모색하고자 하였다. 또한 상수관로 내부의 이물질로 인해 지속적으로 발생하는 수질민원을 해소하고 수돗물에 대한 신뢰성 향상 및 양질의 수돗물 공급을 위한 방안을 마련하고자 하였다. 민원지역에서 포집된 이물질은 관로의 내부부식 및 노후화로 인한 부식생성물의 무기화합물뿐만 아니라 탄소(C) 및 산소(O)성분을 다량 함유한 유기화합물도 포함하고 있었다. 이물질에 대한 정확한 판단과 저감을 위해 객관적인 대상지역의 관상태평가가 필요한 것으로 조사되었다.
