Urban road early runoff rainwater pollutant interception treatment device

Abstract

The invention discloses an urban road early runoff rainwater pollutant interception treatment device. The urban road early runoff rainwater pollutant interception treatment device is characterized by comprising a water inlet pollutant interception diversion module (1), a settling pond module (2), a clear water pond module (3) and a self-controlled water lifting module (4); a water outlet of the water inlet pollutant interception diversion module (1) is connected with a water inlet of the settling pond module (2), a water outlet of the settling pond module (2) is connected with a water inlet of the self-controlled water lifting module (4), a water outlet of the self-controlled water lifting module (4) is connected with a water inlet of the clear water pond module (3) and an irrigation nozzle of a greenbelt surface (5), and a water outlet of the clear water pond module (3) is communicated with the self-controlled water lifting module (4). The urban road early runoff rainwater pollutant interception treatment device achieves cyclic utilization of rainwater resources, is environmentally friendly, efficient, simple and compact in structure, low in cost, economical, affordable, easy to use and feasible, and meets the requirement for ecological water utilization.

Description

technical field [0001] The invention relates to a sewage interception and treatment device for initial runoff rainwater on urban pavement, in particular to a sewage interception treatment device for storing rainfall and purifying initial runoff rainwater in cities, and belongs to the technical field of water conservancy engineering. Background technique [0002] With the development of urbanization, the area of ​​impermeable ground increases at a high speed, leading to the accumulation of pollutants, which makes the rainwater on the road hold a large amount of pollutants. Sansalone.J.J of Germany’s research on road runoff shows that in the initial 20% of rainwater runoff The pollution load of rainwater accounts for 80% of the total rainfall pollution. Therefore, the interception and treatment of initial rainwater can effectively control the water pollution caused by runoff. At present, there are different measures for rainwater pollution treatment at home and abroad. Most of...
