Abstract

The invention discloses an urban road rainfall runoff ecological coprocessing device and a method. The device comprises an urban road rainfall runoff ecological coprocessing box and a bioretention purification unit, wherein an overflow weir board, a second screen mesh partition and a perforation partition are arranged in the urban road rainfall runoff ecological coprocessing box at intervals sequentially; the interior of a box body is divided into an overflow chamber, a water inlet chamber, a water distribution chamber and a bioretention purification chamber that are sequentially arranged by the overflow weir board, the second screen mesh partition and the perforation partition; and the bioretention purification unit is arranged in the bioretention purification chamber, and comprises a gravel layer, a sand filter layer, a planting soil layer and plants. The device and the method can sequentially remove floating matters, particles and soluble pollutants that are in different particle sizes in rainfall runoff, achieve hierarchical control of the pollutants in the rainfall runoff, can store a part of rainfall runoff to meet growth requirements of the plants in the bioretention unit, achieve a water conservation effect, and can also achieve multi-purpose control of water quality and water quantity of the urban road rainfall runoff.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to an urban road rainwater treatment device and an urban road rainwater treatment method. Background technique [0002] my country is in a critical period of building a well-off society in an all-round way, with unprecedented speed and scale. Roads play an important role in urban planning and construction. Under the background of rapid urbanization, the area of ​​roads continues to increase. At present, the proportion of my country's urban roads to construction land is generally 10-15%, and some foreign cities even exceed 30-40%. Therefore, in order to coordinate the contradiction between people and the environment in urban development, how to grasp the increasing relationship between roads and the urban environment, and properly deal with the interference and impact of road construction on the environment and water resources, etc., has become a problem worthy of seriou...
