| Research Abstract |
The objective of this study is to clear the mechanism of fecal coliform bacteria removal in the water purification system (constructed wetland) by predation of protozoa. Seasonal variation of water quality and microfauna in the constructed feeding pond of lake Izunuma were monitored for three years. The effect of waterfowl on the density of coliform bacteria was determined. Escherichia coli was isolated from feces of pintail and swan. A lot of species of protozoa were observed in the pond water, Halteria sp., Bursalia sp.,etc. However, the effect of protozoa to the fate of fecal coliform bacteria was not evaluated.
