APPARATUS FOR PROCESSING CONTAMINANT IN ROAD SURFACE DRAINAGE OF ROAD DRAIN FACILITIES

摘要

According to the present invention, there is provided an apparatus for treating pollutants in a road drainage facility for treating road drainage introduced from a nonpoint source such as a road, a parking lot, and the like. The device stores road drainage coming in through the drainage of the road and the soil, solids and contaminants contained in the drainage, and falls down through the inlet to reduce the falling speed of the road drainage and fall. A road drainage reservoir having means for equally distributing the drop-type road drainage, and a road drainage treatment tank for purifying pollutants in the drainage flowed from the road drainage reservoir as the inflowing road drainage increases; And the road drainage reservoir and the road drainage treatment tank to communicate with each other, and when the road drainage in the reservoir is filled in a predetermined amount or more so that the initial road drainage can be temporarily maintained in the road drainage reservoir. A barrel formed at a height to move to the treatment tank It includes.
