Background
In recent years, the rainwater runoff surface source pollution of most cities in China is serious, and the rainwater runoff surface source pollution becomes an important factor for deteriorating the water quality of the urban river and lake. Solving the problem of rainwater runoff non-point source pollution is one of important ways for improving urban water environment.
At present, the common practice of road rainfall runoff control is to lead rainwater to a non-isolation belt/tree belt of a road machine for infiltration, stagnation and purification treatment, and a certain greening space is required in the road range. In addition, in order to facilitate the introduction of rainwater into the green space, the green space is required to have a certain depth of concavity. Therefore, for a road with a low greening rate or for a road with a concave surface due to the overall view, the general method of controlling the runoff of rainwater according to the road cannot be implemented.
The water quality sampling result of a large amount of road rainfall runoffs shows that the initial scouring effect exists in runoff pollution, and the concentration of the initial rainfall runoff pollutants is obviously higher than that in the later period, so that a better pollution control effect can be achieved only by controlling the earlier-period rainfall runoff pollution.
