Combining the two can accurately realize the separation of rainwater and sewage; rainwater has a high degree of pollution because it washes away the dust, particulate matter, grease, heavy metals and other pollutants accumulated on the road surface and roof; as the rainwater continues to fall, most of the pollutants on the ground are washed away; the above-mentioned combined discharge of rainwater and sewage causes the later rainwater to be discharged into the sewage treatment plant, which increases the treatment burden of the sewage treatment plant and generates unnecessary energy consumption.

[0034] like Figure 2-Figure 5As shown, an outer filter cartridge 22 and an inner filter cartridge 23 are provided in the housing 21. The outer filter cartridge 22 is fixedly connected to the inner wall of the housing 21. The inner filter cartridge 23 is rotatably connected to the inner wall of the outer filter cartridge 22. One end of the inner filter cartridge 23 is connected to a water inlet pipe 26. A sealing seat 25 is fixedly connected to the water inlet pipe 26. The inner filter cartridge 23 is rotatably connected to the sealing seat 25 in a sealed manner, and the water inlet pipe 26 is sealedly connected to the filter cover 24. Rainwater and sewage enter the inner filter cartridge 23 through the water inlet pipe 26. An outlet 236 is provided on the surface of the inner filter cartridge 23. A filter passage 27 is formed between the outer wall of the inner filter cartridge 23 and the inner wall of the outer filter cartridge 22. The filtered matter can pass through the outlet 23 6 enters the filter passage 27; a waterproof reduction motor 5 is installed on the outer filter cartridge 22, and a driving gear 51 is fixedly connected to the rotating shaft of the waterproof reduction motor 5, and a driven gear 235 meshing with the driving gear 51 is coaxially fixedly connected to the inner filter cartridge 23; the inner filter cartridge 23 is driven to rotate slowly by the waterproof reduction motor 5, and the filter material inside is driven to rotate when the inner filter cartridge 23 rotates. When the outlet 236 rotates to the bottom, the filter material enters the filter passage 27 from the outlet 236, and the inner filter cartridge 23 keeps rotating, which is conducive to the filter material entering the filter passage 27 from the outlet 236 and avoiding the blockage of the outlet 236.

[0035] In order to avoid clogging in the filter channel 27, a clearing mechanism is provided between the outer wall of the inner filter cartridge 23 and the inner wall of the outer filter cartridge 22, and the clearing mechanism includes an annular clearing frame 4, which is rotatably connected to the outer wall of the inner filter cartridge 23, and is used to push the filtered material in the filter channel 27 into the filter cover 24; an annular gear ring 41 is rotatably connected to the clearing frame 4, and a plurality of baffles 42 are evenly fixedly connected to the side surface of the gear ring 41 along its circumference, which are used to drive the filtered material to be evenly distributed in the filter channel 27; a first gear 43 meshing with the gear ring 41 is rotatably connected to the clearing frame 4, and the first gear 43 may be provided with one or more first gears, and when the first gear 43 rotates, it drives the gear ring 41 to rotate; a second gear 44 is coaxially fixedly connected to the first gear 43, and the inner filter A rack 231 that can mesh with the second gear 44 is fixedly connected to the cylinder 23.

[0040] During specific implementation: rainwater and sewage enter the inner filter cartridge 23 from the water inlet pipe 26, and the waterproof reduction motor 5 drives the inner filter cartridge 23 to rotate slowly. When the inner filter cartridge 23 rotates, when the outlet 236 rotates to the bottom, the valve plate 237 opens the outlet 236, and the filtered material enters the filter channel 27 from the outlet 236. When the outlet 236 rotates to the top and both sides, the outlet 236 is closed, and when the inner filter cartridge 23 rotates, it drives the gear ring 41 to rotate intermittently, and then drives the baffle 42 to rotate intermittently, so that the filtered material is evenly distributed in the filter channel 27 around the circumference, thereby increasing the amount of debris stored in the filter channel 27; and when the inner filter cartridge 23 drives the cylinder 232 to rotate, it drives the clearing frame 4 to reciprocate, and the clearing frame 4 pushes and compresses the filtered material in the filter channel 27 into the filter cover 24, thereby avoiding blockage of the inner filter cartridge 23 and the outer filter cartridge 22 and extending the cleaning cycle of the filter cover 24.

[0041] This embodiment also discloses a method for using a water treatment water delivery device with flexible interception, based on the above water delivery device, comprising the following steps:
