[0028] Further, as shown in the figure, the embodiments further comprise: a basket grid 7, which is arranged at the water inlet pipe 12 and is used for filtering relatively large pollutants. Figure 1 ​​​As shown, in this embodiment, both the drain gate 131 and the gate valve 5 are controlled to open and close by solenoid valves.

[0029] Furthermore, such as Figure 1 As shown, in this embodiment, it also includes: a control system 9 (which belongs to conventional technology), which is communicatively connected to the solenoid valves of the drainage gate 131 and the gate valve 5, and can control the opening and closing of the drainage gate 131 and the gate valve 5; in addition, the liquid level sensor 4 and the rain gauge are also communicatively connected to the control system 9.

[0030] Working principle:

[0031] In the initial stage of rainfall: Ground pollutants are washed into the interception well by rainwater. The level sensor 4 detects the rise in water level. Due to the high degree of pollution in the initial rainwater, when the water level rises to the set height, the control system 9 instructs the sewage pump 3 to start and the drain gate 131 to close, trapping the initial rainwater and pollutants in the interception well. The sewage pump 3 then pressurizes and sends the water to the sewage treatment plant for treatment, thus avoiding pollution of natural water bodies.

[0032] Mid-rainfall period: As rainfall continues, rainwater continuously flows into the interception well, and the water in the interception well becomes relatively clean. When the water level reaches a certain height, the level sensor 4 transmits the information to the control system 9 again. The control system 9 instructs to shut down the sewage pump 3 and open the drainage gate 131. The relatively clean rainwater is discharged into the rainwater pipe network or river through the drainage gate 131, achieving reasonable discharge.

[0033] On sunny days: mainly domestic sewage and industrial wastewater flow into the interception well. The water level monitored by the level sensor 4 is received by the control system 9. When the water level reaches a certain height, the sewage pump 3 is turned on and the drain gate 131 is closed to ensure that the sewage flows smoothly to the sewage treatment plant for treatment.

[0034] When the rainfall monitoring instrument 8 detects excessive rainfall, the control system 9 controls the drainage gate 131 to close to prevent river water from flowing back into the river.

[0035] Interception wells, through intelligent control and precise liquid level monitoring, can accurately separate rainwater and sewage under different weather and water flow conditions, effectively protecting the urban water environment. For example, at the beginning of rainfall, the intelligent control system intercepts heavily polluted rainwater to prevent it from polluting natural water bodies; on sunny days, it ensures that sewage is effectively treated, preventing untreated sewage from entering natural water bodies. This design not only improves the efficiency of the drainage system but also provides strong support for the sustainable development of the city.

[0036] Above, refer to Figure 1 The present invention describes an intercepting well according to an embodiment of the present invention, which, through intelligent control and precise liquid level monitoring, can accurately achieve rainwater and sewage separation under different weather and water flow conditions, effectively protecting the urban water environment.
