Curb capable of collecting and purifying rainwater

Abstract

The invention relates to a curb capable of collecting and purifying rainwater. The curb comprises a hollow curb body arranged on the edge of a subgrade; a rectangular hollow groove is formed in one side, close to the subgrade, of the hollow curb body; a grating plate is arranged at the upper part of the rectangular hollow groove; a cavity water storage layer, a filtering layer, an oil removal layer, a first purifying layer and a second purifying layer are arranged inside the rectangular hollow groove from top to bottom in sequence; a drainage pipe is arranged at the bottom of the rectangular hollow groove. The curb capable of collecting and purifying the rainwater, provided by the invention, can effectively collect and discharge the highway pavement runoff and retard the urban flood disaster, not only has a good removal effect on conventional pollutants, but also can effectively remove heavy metals, grease, oil and other pollutants hard to remove by adopting a conventional method. The water collected by the drainage pipe can be directly taken as irrigation water, landscape water, car washing water and other domestic water and cannot cause pollution to a water body and soil.
