Embodiment 1

[0047] Such as figure 1 As shown in the road rainwater treatment system, the municipal rainwater main pipe 1 is connected to the natural water body 2, the first shunt well 3 is arranged on the municipal rainwater main pipe 1, and the first shunt well 3 is at the water inlet 4 position. 3 On the front side, the position of the first diversion well 3 and the first water outlet 5 is the back side of the first diversion 3 well;

[0048] The water inlet 4 of the first branch well 3 is in communication with the municipal rainwater main pipe 1 on the front side of the first branch well 3, and the first water outlet 5 of the first branch well 3 is connected to the first branch well 3 The municipal rainwater main pipe 1 on the rear side of the well 3 is connected, and the downward weir gate 7 is arranged at the first outlet 5 of the first branch well 3; the second outlet of the first branch well 3 The water port 6 is located on the side wall of the first split well 3, the second water ou...

Embodiment 2

[0051] A control method of the road rainwater treatment system in embodiment 1, the control method includes:

[0052] On sunny days, the downwardly-opening weir gate (or gate) set at the first outlet of the first diversion well is in a blocking state, and the gate set at the second outlet of the first diversion well is in an open state; the rainwater main pipe is wrong The mixed domestic sewage enters the second diversion well, and flows into the regulating storage tank through the first outlet of the second diversion well. The domestic sewage in the regulating storage tank flows to the sewage treatment plant by gravity for treatment. At the maximum flow rate of the interception pipe of the sewage treatment plant, the domestic sewage will be stored in the regulating storage tank. When the water volume in the regulating storage tank reaches the maximum storage capacity, the domestic sewage flows into the line through the second outlet of the second branch well Treatment device, th...

Abstract

The invention provides a road rainwater treatment system. The system comprises a municipal rainwater main pipe and one or more rainwater treatment units, wherein the municipal rainwater main pipe is connected to a natural water body; a first distributing well water inlet is arranged at the front side of each first distributing well; a first distributing well first water outlet is arranged at the back side of each first distributing well; each first distributing well water inlet communicates with the municipal rainwater main pipe which is arranged at the front side of the corresponding first distributing well; each first distributing well first water outlet communicates with the municipal rainwater main pipe which is arranged at the back side of the corresponding first distributing well; anintercepting device is arranged on each first distributing well first water outlet; a first distributing well second water outlet is connected to a second distributing well water inlet; a second distributing well first water outlet is connected to a regulation and storage facility; and a second distributing well second water outlet is connected to an online treatment device. With the applicationof the system provided by the invention, a water body can be fully purified, so that the water quality safety of the water body which is discharged into the natural water body can be guaranteed.

Description

Technical field [0001] The invention relates to the technical field of water treatment, in particular to a road rainwater treatment system and control method. Background technique [0002] There will be a municipal rainwater main pipe under the municipal road. When it is sunny and rainy, the sunny sewage and first rain along the road will enter the rainwater main pipe under the municipal road from the gutter beside the municipal road, and then directly drain to the natural water body. [0003] At present, the water entering the rainwater main pipe is directly discharged to the natural water body without any treatment, which is bound to cause serious pollution to the natural water body. For example, the mismatched domestic sewage in the sunny day will enter the rainwater main pipe and be discharged into the natural water body. , Pollute the natural water body; the initial rainwater containing a lot of pollutants enters the rainwater main pipe and is discharged into the natural water...
