초록

This paper is focusing on the rain water quality characteristics by various materials for collection and storage. Materials for the collection surface were cement, cement composit polyurethane and steel sandwich funnel. Three storage tanks were provided for each collection surface, of which materials were stainless steel, cement and PVC. The water quality was monitored at each storage tank after collection. Higher pH values observed at the rainwater stored in the cement storage tank compared to two other materials. This was caused by the alkalinity which is the major component of cement. While other parameters (Hardness, T-S, KMnO4 consumption, NH4+-N, Zn, Al) were at similar level for the three materials of the storage tank. About sulfate ion and turbidity, there was not obvious effects of the materials on water quality. Regardless the materials of collection surface and storage tank, the rain water quality could meet Korean drinking water standard in terms of hardness, TS, NO3-N, Zn and SO42-. However concentrations of KMnO4 consumption, NH4+-N and Al were above the standard, which means they should be treated for a use of drinking water. It was recommended that stainless steel and PVC were proper to keep the rain water quality in clean condition for expended period of use.
