| Abstract |
In this study, we perlormed 8 times of water quality sampling surveys and conducted continuous measurement of flows to identify wastewater flow characteristics for wastewater treatment basins of Guri city. The field survey has been conducted 6 times in dry weather period and 2 times in wet weather period. Each survey conducted 24-hr water quality sampling in the interval of 2-hr. Using automatic flowmeter. we obtained wastewater flow record in the interval of 10 minutes for more than MI days. From the analysis of flow data and water quality data the following conclusions can be drawn. Flow of Guri-1 station. which represents residential and commercial mixed area, rises early in the morning before office-going hour and moves UP and down within narrow range. and lasted alter office-leaving hour, resulting from continuous commercial activity. In contrast, Guri-3 station representing community and Guri-4 station representing residential area, the flow immediately falls down after rising early in the morning and later rises again at the olfice-leaving hour, and arrives at peak llows around late evening . In the analysis of wastewater characteristics for weekdays and weekends, without landuse types the flow rate of weekends is higher than that of weekdays because it rellects population being not contributed to generate wastewater during the working hours of weekdays stay home and produce wastewater for weekends period. |
