Embodiment 1

[0054] Such as figure 1 In the road rainwater treatment system shown, the municipal rainwater main pipe 1 is connected to the natural water body 2, the diversion well 3 is arranged on the municipal rainwater main pipe 1, the position of the water inlet 4 of the diversion well 3 is the front side of the diversion well, and the diversion well 3 The position of the first water outlet 5 is the rear side of the diversion well;

[0055] The water inlet 4 of the diversion well 3 communicates with the municipal rainwater main pipe 1 on the front side of the diversion well 3 , and the first water outlet 5 of the diversion well 3 communicates with the municipal rainwater main pipe 1 on the rear side of the diversion well 3 . The rainwater main pipe 1 is connected, and the lower opening weir gate 7 is arranged at the first water outlet 5 of the diversion well 3; the second water outlet 6 of the diversion well 3 is located on the side wall of the diversion well 3, and A gate 8 is set at ...

Embodiment 2

[0058] A control method of the road rainwater treatment system in Embodiment 1, the control method comprising:

[0059] On sunny days, the bottom-opening weir gate installed at the first water outlet of the diversion well is in the intercepting state, and the gate installed at the second water outlet of the diversion well is in the open state; The particle separator intercepts the larger particles and floating objects in the domestic sewage, and then flows into the cylindrical filter to intercept the smaller particles in the domestic sewage for a second time, and the treated domestic sewage is directly discharged to the rainwater main pipe .

[0060] When it rains, when the rainfall is within the maximum processing capacity of the particle separator and the cylindrical filter, the lower opening weir gate set at the first water outlet of the diversion well is in the interception state, and the second water outlet of the diversion well The sluice gate set at the rainwater main ...

Abstract

The invention provides a road rainwater treatment system. The system includes a municipal rainwater main pipe and a rainwater treatment unit. The municipal rainwater main pipe is connected to a natural water body. The rainwater treatment unit includes a diversion well, a flow interception device, a first filter device, and a second filter device. The diversion well is set on the municipal rainwater main pipe. When the diversion well is a trough type, there is no interception device; the position of the water inlet of the diversion well is the front side of the diversion well, and the position of the first water outlet of the diversion well is the rear side of the diversion well; The water inlet of the well is connected to the municipal rainwater main pipe on the front side of the diversion well, the first water outlet of the diversion well is connected to the municipal rainwater main pipe on the rear side of the diversion well, and the intercepting device is arranged at the first water outlet of the diversion well; The second water outlet is connected to the first filter device and the second filter device in sequence, and the water outlet of the second filter device is connected to the municipal rainwater main pipe on the rear side of the diversion well. The system provided by the invention can fully purify the water body and ensure the safety of the water discharged into the natural water body.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a road rainwater treatment system and a 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 rain outlet next to the municipal road, and then be directly discharged to the natural water body. [0003] At present, after the runoff rainwater from the road enters the rainwater main pipe, it is directly discharged into the natural water body without any treatment, which will inevitably cause serious pollution to the natural water body. The initial rainwater containing a large amount of pollutants enters the rainwater main pipe and is discharged to the natural water body without any treatment, which also seriously pollutes the natural water body. [0004] Therefore, ...
