Embodiment 1

[0032] 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 3, and the diversion well 3. The position of the first water outlet 5 is the rear side of the diversion well 3;

[0033] 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 se...

Embodiment 2

[0036] A control method of the road rainwater treatment system in Embodiment 1, the control method comprising:

[0037] On sunny days, the lower opening weir gate (or gate) set at the first water outlet of the diversion well is in the intercepting state, and the gate set at the second water outlet of the diversion well is in the open state; The domestic sewage passes through the gate set at the second water outlet of the diversion well and first enters the particle separator to intercept the larger particles and floating objects in the domestic sewage, and then flows into the storage tank for storage, and the sewage treatment plant is capable of processing For sewage, the domestic sewage stored in the storage tank will flow into the sewage treatment plant through the sewage pipeline for treatment;

[0038] When it rains, the lower opening weir gate (or gate) set at the first water outlet of the diversion well is in the intercepting state, and the gate set at the second water o...

Abstract

The invention provides a road rainwater treatment system. The system comprises a municipal rainwater main pipe and a rainwater treatment unit, the municipal rainwater main pipe is connected with a natural water body, a shunting well is arranged on the municipal rainwater main pipe, and when the shunting well is in a tank type, an intercepting device is not arranged; a water inlet of the shunting well is formed in the front side of the shunting well, and a first water outlet of the shunting well is formed in the rear side of the shunting well; the water inlet of the shunting well is communicated with the portion, at the front side of the shunting well, of the municipal rainwater main pipe; the first water outlet of the shunting well is communicated with the portion, at the rear side of theshunting well, of the municipal rainwater main pipe; the intercepting device is arranged at the first water outlet of the shunting well; a flow control device is arranged at a second water outlet of the shunting well, the other end of the flow control device is sequentially connected with a first filtering device and a regulation and storage facility, and a water outlet of the regulation and storage facility is communicated with a sewage pipeline. By means of the system, the water body can be fully purified, and the water quality safety of the discharged natural water body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water 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, the water entering the rainwater main pipe is directly discharged to the natural water body without any treatment, which will inevitably cause serious pollution to the natural water body. , pollute 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, there...
