It is installed in the drainage tank horizontally and parallelly. Several U-shaped sewage boxes are connected to several filtering and drainage boxes through siphon filtering structures, respectively. Several U-shaped sewage boxes are respectively installed with solid-state shunt structures. The solid-state shunt structures include: Cover plate, circular filter box, filter screen, circular extrusion block, several filter sliders with the same structure and several fixed sliders with the same structure; several filter sliders are evenly installed on the sidewall of the circular filter box On the upper part of the U-shaped sewage box, there are several filter slides with the same structure.

By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are known in the art. The following mainly introduces the working principle and process.

Example: rainwater flows into the loop filter box 6 in the U-shaped displacement box 2 through several drainage holes 25 on the cover plate 5, and the sand in the rainwater is filtered through the filter screen 7 in the loop filter box 6 At the same time, the filter screen 7 on the return-shaped extrusion block 8 is closely attached to the return-shaped filter box 6, and at the same time, the return-shaped filter box 6 can quickly enter the U-shaped sewage box 2 through several filter sliders 9 on it. The inside is opened and lifted, and at the same time, it is quickly drawn into the fixed slideway 12 in the return-shaped filter box 6 through several fixed sliders 10 on the return-shaped extrusion block 8, and the sand and gravel are filtered out through the filter screen 7, and at the same time pass through The air pressure makes the height of the rainwater on the side of the loop-shaped filter box 6 in the U-shaped sewage box 2 consistent with the liquid height in the loop-shaped siphon filter box 13 in the U-shaped sewage box 2. The filter plate 15, the quartz sand filter plate 16 and the heavy filter plate 17 filter the rainwater, which refers to the filter material [1] with a specific gravity less than 1 or close to 1. Commonly used are plastic balls, plastic beads, fiber balls, etc. When filtering with light filter media, the water flow is generally bottom-up, but can also be top-down. A fixed pressure screen or pressure plate is often set up and down the filter material layer to prevent the loss of the filter material. The fillers mainly include glass fiber reinforced plastic or plastic honeycomb fillers, three-dimensional corrugated fillers, soft fiber fillers, semi-soft fillers and irregular granular fillers (sand, crushed stone, slag, coke, anthracite), etc. FRP or plastic fillers have a smooth surface, poor adhesion of biofilms, easy to age, and are prone to blockage of fillers to varying degrees in actual use; the water flow in soft fillers is not ideal, and is easily bonded by biofilms. The phenomenon of nodulation occurs, which greatly reduces the surface area, and then anaerobic effect occurs inside the nodule, which affects the treatment effect. Irregular granular packing has large water flow resistance, which is easy to cause blockage of oxidation tank. In recent years, China has also carried out research on the application of flake ceramsite to treat micro-pollution of water source water. Flake ceramsite is an irregular granular filler. Although the film has good performance, it has large water flow resistance, is easy to block, has poor strength, and is easy to break. It is not resistant to water scouring, which limits it to the micro-pollution treatment of water source water. Quartz sand is used as a filter medium to filter water with high turbidity through a certain thickness of granular or non-granular quartz sand under a certain pressure. Effectively intercept and remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, smell and some heavy metal ions in water, and finally achieve a high-efficiency filtration that reduces water turbidity and purifies water quality. The height of the inner liquid reaches a certain height, and the liquid above a certain height in the U-shaped sewage tank 2 is drained into the filtering and drainage tank 3 through the drainage pipe 18 on the U-shaped sewage tank 2. When the liquid in the U-shaped sewage tank 2 flows into When it reaches the filtering and drainage box 3, the force of the liquid flowing in makes the anti-reverse shielding plate 20 rotate out of the shielding groove 22 through the shielding shaft 19. The reverse shielding plate 20 is closely attached to the shielding groove 22, and the liquid is drained away through the filtering and drainage pipes 23 on the several filtering and drainage boxes 3. The siphon filter box 13 takes out the filtered material to avoid clogging.
