[0016] See Figures 1-6 This utility model provides a novel high-efficiency integrated filtration device for water treatment, comprising: a flocculation zone 1, a sedimentation zone 2, and a filtration zone 7. The flocculation zone 1 and the sedimentation zone 2 are connected, and the filtration zone 7 is located outside the flocculation zone 1. The flocculation zone 1 includes a flocculation tank, a flocculation baffle zone 3, a flocculation guide tube 4, and a flocculation inlet 5. The bottom of the flocculation baffle zone 3 is provided with a connecting pipe 15 connected to the flocculation guide tube 4. The sedimentation zone 2 includes an inclined plate filling zone 17, a water collection tank 16, a sedimentation product outlet 6, several sets of sludge storage hoppers 18, and several sets of sludge discharge pipes. 19. The water collection tank 16 is located at the top of the inclined plate filling area 17. The water collection tank 16 is connected to the sedimentation water outlet 6. Several sets of sludge storage hoppers 18 and sludge discharge pipes 19 are located at the bottom of the inclined plate filling area 17. The filtration area 7 includes an inlet tank 9, an inlet water distribution tank 10, a water storage area, and a filter water outlet 11. The top of the inlet tank 9 is located below the sedimentation water outlet 6. The inlet water distribution tank 10 is connected to the inlet tank 9. The water storage area is located inside the filtration area 7 and is connected to the filter water outlet 11.

[0017] See Figures 1-6 Preferably, the filtration zone 7 of this invention is provided with a fiber ball filling zone 8, the top of the fiber ball filling zone 8 is provided with a fiber ball filter pool, the bottom of the fiber ball filling zone 8 is provided with a filter plate 21, the filter plate 21 is located at the top of the water storage zone, and the colloidal clumps are filtered and retained through the fiber ball filling zone 8.

[0018] See Figures 1-6Furthermore, the filter area 7 of this utility model is provided with a backwash water tank 22 on one side, a backwash water inlet 12 on the top of the backwash water tank 22, and a backwash drain outlet 13 on one side of the backwash water tank 22. Backwashing can rinse away impurities in the water flow, which is convenient for subsequent use.

[0019] See Figures 1-6 Even better, the top of the fiber ball filling area 8 of this utility model is provided with an interception frame 20, which intercepts the fiber balls.

[0020] See Figures 1-6 Finally, the bottom of one side of the filter zone 7 of this utility model is provided with an air washing inlet 14, which is located at the top of the backwash water inlet 12, and gas is introduced to enhance the friction cleaning of the fiber balls.

[0021] The working principle of this utility model: After adding flocculant to the raw water, it enters the flocculation baffle zone 3 through the flocculation inlet 5. The up-and-down folding of the water flow increases the disturbance of the water flow, promoting the collision of smaller colloids in the water and forming small flocculent clumps. Then, it enters the flocculation guide tube 4 from the bottom through the connecting pipe 15 and flows from bottom to top. Relying on gravity, the flocculent clumps gradually gather, increasing the collision probability and forming larger colloid clumps. A frame structure is provided at the top of the flocculation guide tube 4, and a speed reducer can be installed at the top of the flocculation guide tube 4 to further promote the collision of colloids and form larger flocculent clumps that flow into the sedimentation zone 2.

[0022] Water in flocculation zone 1 flows from top to bottom through the top of flocculation guide tube 4, and then enters sedimentation zone 2 through the bottom of the plate between flocculation zone 1 and sedimentation zone 2. After entering sedimentation zone 2, the water first passes through inclined plate filling area 17. The staff will pre-install honeycomb inclined plates in inclined plate filling area 17. Under the obstruction of the honeycomb inclined plates and the action of its own gravity, the large flocs of water roll down into the sludge storage hopper 18 at the bottom of sedimentation zone 2 and are discharged through sludge discharge pipe 19. Since the water flows from bottom to top in sedimentation zone 2, the water will flow through water collection tank 16 and be collected and flow out from sedimentation water outlet 6.

[0023] Water overflowing from sedimentation outlet 6 enters inlet tank 9. After flowing to inlet distribution tank 10, the water in inlet tank 9 is evenly dispersed and flows into fiber ball filling area 8 to filter and retain colloidal aggregates. The interception frame 20 can intercept the fiber balls. At the same time, the bottom of fiber ball filling area 8 is provided with filter plate 21, which is full of holes and equipped with water caps. Then the water flows to the water storage area and finally flows from the filter tank outlet to the water production tank under static pressure.

[0024] When backwashing is required, the water flows through the backwash inlet 12 to the filter plate 21, and then through the water cap on the filter plate 21 into the fiber ball filtration zone 7. The reverse water flow causes the fiber balls to rise and tumble, thereby rubbing and washing away the attached filter impurities. The backwash water flows upward to the backwash water tank 22 to carry away the filter impurities and is discharged from the backwash drain 13.

[0025] When air washing is required, the air intake path for air washing is the same as that for backwashing. The principle of air washing is to introduce gas to enhance the friction and cleaning of the fiber balls when they are lifted up during backwashing.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
