The present invention relates to a device for treating pollutants in initial rainwater and pollutants in a combined sewer pipe. When initial rainwater and sewage passing through a coarse screen flow into a radial filtration device, a vortex is formed and precipitation of heavy impurities is accelerated by the influence of the vortex. Also, the initial rainwater and the sewage flow from the center to the outside in a radial shape and pass through the radial filtration device. Through such a process, the device for treating pollutants in initial rainwater and pollutants in a combined sewer pipe according to the present invention filters the pollutants. The treated water moves to the lower part of a cone-shaped plate and a uniform up flow is formed toward a ware located in the upper part of a filter tank. The treated water is re-treated after passing through a suspended filter film formed at the front surface in the upper part of the filter tank and is discharged from the ware. Therefore, the treatment efficiency of sewage is maximized and the pollutants in initial rainwater and the pollutants in a combined sewer pipe (CSO) can be easily treated. Also, the device can be installed in a small space by minimizing the area of the site where the device is installed. |
