본 연구의 목적은 건물지붕에서 흘러내리는 빗물의 효용을 극대화하기 위해 시간에 따른 지붕 빗물의 성상을 분석하고, 소독하지 않은 저장 빗물과 염소 소독된 저장 빗물의 성상변화를 추적하는데 있다. 이를 위하여, 저장 빗물의 COD, T-N, T-P, 장내미생물, 일반미생물의 시간에 따른 변화를 염소 주입 농도별로 분석하였다. 소독된 저장 빗물의 경우 장내 미생 물 및 일반 미생물은 염소 주입 후 2주 이내에 99% 저감을 확인하였다. 따라서, 지붕 빗물을 장기 보관할 경우, 소독 후 보관하는 것이 저장 빗물의 수질 유지에 도움을 주며 장기적으로 여러 용도에 사용하기 적합할 것으로 판단된다.

The purpose of this study is to monitor the rainwater flowing from the roof of buildings and to maximize the effectiveness of the rainwater storage. This study also analyses the changes in rainwater characteristics before and after subsequent chlorination disinfection. The stored rainwater was disinfected by chlorine and then analyzed for COD, TN, TP, enteric bacteria, and general microbial population changes over time. There was an observed 99% reduction of enteric bacteria and common microbes within two weeks after chlorine injection. Thus, chlorine disinfection of rainwater improves water quality for long-term storage and future use.
