Problems solved by technology

When the flow rate of rainwater decreases, sediment will settle and accumulate in the drainage pipe network, which will pollute the relatively clear rainwater in the later stage. Over time, it will lead to a decrease in the drainage system's water-through capacity, hindering the timely drainage of rainwater, and even clogging the rainwater outlet and pipes

Embodiment 1

[0063] Such as Figure 1-7 Shown, a kind of rainwater sewage interception device based on synchronous sewage interception and treatment, comprises rainwater grate 1, rainwater collection well 2, treatment well 3, drainage well 4; The upper end is divided into a filter area 5 and a storage area 6 by a vertical partition, the bottom plate of the filter area 5 is inclined, and a vertical conveyor belt 7 is installed at the bottom of the bottom plate, and the output of the vertical conveyor belt 7 The rainwater collection well 2 is equipped with a mud-water separation structure, an anti-sludge resuspension structure, and a sludge degradation structure in sequence from top to bottom. The well 4 is connected, and the first drainage pipe 8 is located above the mud-water separation structure, and its bottom is connected with the treatment well 3 through the sludge pipe 9; the treatment well 3 is sequentially installed with a dosing box 10, a counter Sludge resuspension structure, dos...

Embodiment 2

[0070] Such as Figure 8-12 As shown, this embodiment has made further improvements on the basis of Embodiment 1, for example: the center of the mud-water separation block 18 has a support shaft 1801 extending to both sides, and the support shaft 1801 is rotatably connected to the rectangular frame 17, A torsion spring 19 is arranged between the support shaft 1801 and the rectangular frame 17. When the torsion spring 19 is in a natural state, the mud-water separation block 18 is a triangular prism structure placed upright.

[0071] Furthermore, it can also be considered in this embodiment, and also includes an interference overflow structure, which includes:

[0072] The support frame 20 is installed horizontally in the rainwater collection well 2, and is located between the rainwater grate 1 and the mud-water separation structure; the interference detection component includes a support rod 21, and a water storage tank 22 located at one end of the support rod 21. The support ...

Embodiment 3

[0086] The sewage interception method of the rainwater sewage interception device based on synchronous sewage interception and treatment comprises the following steps:

[0087] Step 1: Rainwater and the pollutants it carries flow down into the rainwater collection well through the upper opening of the rainwater grate, and the rainwater grate can intercept larger solid pollutants in the rainwater runoff;

[0088] Step 2: Under the transmission of the vertical conveyor belt, the larger solid pollutants are gradually transferred to the storage area for storage;

[0089] Step 3: Execute step 4 when the rainfall is large, and execute step 5 when the rainfall is small;

[0090] Step 4: The interference and overflow structure starts to work, and the mud-water separation blocks rotate on their respective support shafts at the same time, so that the gap between each mud-water separation block is reduced, and the rainwater is directed to the first drainage pipe and enters the drainage w...

Abstract

The invention relates to the field of environmental protection, in particular to a rainwater sewage interception device based on synchronous sewage interception and treatment. The device comprises a rainwater grate, a rainwater collection well, a treatment well and a drainage well. The rainwater grate is detachably mounted at the upper end of the rainwater collection well; the interior of the rainwater grate is divided into a filtering area and a storage area by a vertical partition plate; a bottom plate of the filtering area is obliquely arranged, and a vertical conveyor belt is mounted at the lowest position of the bottom plate; a sludge-water separation structure, an anti-sludge resuspension structure, and a sludge degradation structure are sequentially mounted in the rainwater collection well from top to bottom; one side of the rainwater collection well is connected with the drainage well through a first drainage pipe; the bottom of the rainwater collection well is connected with the treatment well through a sludge pipe; a dosing tank, the anti-sludge resuspension structure, a dosing stirring structure and a filler structure are sequentially mounted in the treatment well from top to bottom; one side of the treatment well is connected with the drainage well through a second drainage pipe; and a water collecting pipe is arranged at one side of the drainage well. According to the rainwater sewage interception device based on synchronous sewage interception and treatment, the drainage requirement can be guaranteed, particles such as silt entering urban water are reduced, and the flood prevention function of a gutter inlet is not affected.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a rainwater sewage interception device and a sewage interception method based on synchronous sewage interception and treatment. Background technique [0002] Since the initial rainwater has the function of leaching, scouring and transporting the pollutants collected on the ground, the concentration of pollutants in the rainwater at the beginning of the rainfall is relatively high. The concentration is the highest. Even if the rainwater is collected, recycled and purified, the larger garbage intercepted into the stormwater outlet and the removal of sediment and other particulate matter in the rainwater runoff are limited by the traditional stormwater outlet structure. When the rainfall intensity is high, most of the sediment and other particles carrying nitrogen, phosphorus and other chemical substances will directly enter the urban water body with the...
