Focus on the water pollution in lakes and rivers, we should have to measure for point pollutants, such as domestic sewage and industrial wastewater by devising various counteractions. To improving the water quality, use point pollutant measures is limited. By the research, the vortex type facilities are adopted to removal of sediments, oils and floatables from storm water runoff. the results of the precede research are about the Vortex type facility and setting the slope plate to make the facility strong, combine with the filter type which is the media sponge 60ppi, 80ppi on the upflow and zeolite diameter 4:1 ratio. the sampling site was set at do-chung bridge in the north of deagu, where has a lot of traffic in every day. The rain water is collected and treated by treatmet plant under do-chung bridge. The treatment plant capacity is 30 m3-hr with the rainfall intensity 10 mm-hr in bridge 888 m2 area. At the treatment plant had done 12times to take a sampling from August 2008 to October 2009. the results of the facility treatment efficiency are follows by TSS 22.1%~91.7%, BOD5 12.7%~71.5%, CODMn 9%~49.8%, TP 46%~74.5%, PO4 77.8%~88.8%, NO3 15%~84.6%, TN 42.1%~88.3%, Cu 17.1%~100%, Fe 1.7%~81.8%, Zn 11.7%~90.6%. by using the vortex type facility and filter facility in this research, the quality of water source can be improved.
