Problems solved by technology

[0004] (2) Serious runoff pollution: After concentrated urbanization, the impermeable area of ​​roads has increased sharply, and due to frequent human activities, runoff pollution has been serious
[0005] (3) Loss of rainwater resources: The traditional road drainage mode based on "fast drainage" focuses on quickly collecting rainwater and draining it from the road. The flow increases and the rainwater resources are lost in vain
In addition, the traditional "quick discharge" concept does not follow the natural cycle of water resources, and it is difficult to regulate the micro-environment and micro-climate; and a large amount of rainwater discharge increases the burden on the pipe network and sewage treatment plants

Abstract

The invention relates to the field of rainwater treatment, and discloses a combined device for treating road runoff rainwater. The combined device comprises a first water tank, a guide chamber and a second water tank. The guide chamber is arranged between the first water tank and the second water tank. A perforated plate is arranged at the upper end of the guide chamber. A micro wet-land unit is arranged on the upper side of the guide chamber. A rainwater strainer is arranged at the top of each of the first water tank and the second water tank. Cobblestones are piled on the rainwater strainers. A mud guard and a guide plate are arranged in the first water tank. A mud collection groove is formed in the bottom of the first water tank. The mud guard is arranged on one side of the mud collection groove and inclines toward one side of the guide chamber. A water outlet is formed in the wall of the second water tank. A water outlet pipe is arranged on the wall, opposite to the water outlet, of the second water tank and is used for being connected with a municipal rainwater pipeline. The combined device has the advantages that discharge of runoff rainwater pollutants can be reduced and runoff volume and runoff peak can be decreased.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a combined device for treating road runoff rainwater. Background technique [0002] Road is a very important part of urban planning and construction, and road drainage design is an indispensable part of road construction. With the rapid development of urbanization, the road area continues to increase, and the road drainage problem is also facing new challenges. The traditional "quick drainage" pipe drainage mode has brought a series of rainwater problems to the city: [0003] (1) Frequent occurrence of waterlogging: The increasing area of ​​impermeable roads leads to an increase in the comprehensive runoff coefficient, faster rainwater confluence speed, shorter confluence time, and an increase in the total and peak value of road runoff; this makes the traditional pipeline drainage "overwhelming" Phenomenon, when the load of the drainage pipe network is exceeded, wate...
