DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Furthermore, a water inlet pipe 1 is installed at one end of the well body 2 .

[0024] Furthermore, a water outlet pipe 7 is installed at the other end of the well body 2 .

[0025] Furthermore, a screen hanging ring 11 is installed on the upper end surface of the hydraulic decontamination screen 10, and two screen hanging rings 11 are provided.

[0026] Furthermore, a hidden manhole cover 12 is provided on the upper end surface of the manhole body 2 .

[0027] Furthermore, the surface of the hydraulic decontamination screen 10 is provided with a center-opened screen slag discharge hole 13 .

[0028] Furthermore, a multi-layered decontamination filler structure is arranged inside the decontamination medium structure layer 4 .

[0029] Working principle: When in use, a hydraulic decontamination screen 10 is installed inside the well body 2. The hydraulic decontamination screen 10 and the well body 2 are detachable structures. The center position of the hydraulic decontamination screen 10 is connected to a screen fixing bracket 8 arranged inside the well body 2 through a screen rotating shaft 9. Rainwater flows in from the water inlet pipe 1 and is filtered by the hydraulic decontamination screen 10. Most of the floating objects in the rainwater will be intercepted and collected in the frame of the hydraulic decontamination screen 10. At the same time, particles larger than the mesh size will also be intercepted by the filter frame.

[0030] Through the installation angle of the water inlet pipe 1, the hydraulic decontamination screen 10 can realize unpowered rotation after water enters, so that the hydraulic decontamination screen 10 is more efficient, less prone to clogging, longer single-time use time, and lower maintenance frequency. The hydraulic decontamination screen 10 is mainly used to intercept and collect floating objects and particles of a certain particle size. The decontamination medium structure layer 4 in the sedimentation area can be flexibly replaced according to water quality and decontamination requirements. The decontamination medium structure layer 4 can use degreasing media to absorb oil and grease in rainwater, and dephosphorization filter materials can also be used to remove pollutants such as nitrogen and phosphorus.

[0031] At the bottom of the well body, three sedimentation chambers are divided by the overflow retaining wall 3 and the outlet retaining wall 6. When rainwater flows into the device from the water inlet pipe 1, the flow rate of rainwater decreases, and a large amount of particles carried in the rainwater will settle during the flow. When the rainwater flows through the overflow retaining wall 3, the particles are blocked by the overflow retaining wall 3 and deposited at the bottom of the pre-sedimentation area. Clean rainwater overflows from the top of the overflow retaining wall 3, and the rainwater flows through the decontamination medium structure layer 4 in the sedimentation area for adsorption and reaction. Finally, the rainwater is further filtered through the outlet grille 5 and discharged to the drainage area, and discharged from the outlet pipe 7 after overflow.
