Flocculation sedimentation clarification is a way to treat sewage using physical and chemical principles. It is widely used in the sewage treatment industry because of its simple process flow and easy operation. By adding coagulants and flocculants to sewage, suspended solids and some soluble pollutants in the water are separated and removed by flocculation and sedimentation.

[0003] For example, a patent entitled: A Magnetic Flocculation and Clarification Wastewater Treatment Device (patent application number: CN201820029238.0) discloses a magnetic flocculation and clarification wastewater treatment device, which connects a coagulation reaction tank, a magnetic tank, a flocculation reaction tank and a sedimentation tank to each other in an up-and-down manner to form an S-shaped passage, and adds a coagulation reaction agent, magnetic powder and flocculant to the coagulation reaction tank, the magnetic tank and the flocculation reaction tank, so that the coagulation reaction and the flocculation reaction are carried out separately, and the reaction is more complete and thorough. However, since the coagulation reaction tank, the magnetic tank and the flocculation reaction tank are interconnected, when the coagulation reaction agent, magnetic powder and flocculant are poured in, some materials tend to float on the surface of the sewage and cannot react completely, and the materials tend to mix with each other, resulting in an uneven reaction.

[0008] Preferably, a layer of cleaning cloth is fixed to the outside of the three square frames, and the cleaning cloth is attached to the corresponding coagulation tank, magnetic tank and flocculation tank. A support plate is fixed on the other side of the top of the coagulation tank, magnetic tank and flocculation tank.

The bottom ends of the first tank body, the second tank body and the third tank body are connected to discharge pipes, and the bottom ends of the discharge pipes extend into the corresponding bottom ends of the filter screens.

[0009] Preferably, the filter screen is provided with a through hole for the discharge pipe to pass through, and the height of the square frame is higher than the height difference between two adjacent partitions.

[0017] Technical effects and advantages of the present invention:

[0018] 1. When the first tank body, the second tank body and the third tank body add reactants to the corresponding coagulation tank, the magnetic tank and the flocculation tank respectively, the corresponding square frames are moved up and down to make the square frames seal the connections between the coagulation tank, the magnetic tank and the flocculation tank for a short time to avoid the materials in the coagulation tank, the magnetic tank and the flocculation tank from mixing with each other, thereby improving the clarification efficiency. The coagulation tank, the magnetic tank and the flocculation tank each form a closed space, so that the materials and sewage can be fully mixed and reacted.

[0019] 2. Since the materials discharged from the first tank body, the second tank body and the third tank body are discharged into the corresponding bottom of the filter screen through their respective discharge pipes, when their respective square frames move up and down, the connection is opened, and the downward pressure of the filter screen can drive the materials to move downward, thereby preventing the materials from being affected by buoyancy and floating on the sewage surface, affecting the reaction efficiency. In addition, when the square frame moves up and down, the cleaning cloth on the outside of the square frame can rub against the corresponding coagulation tank, magnetic tank, flocculation tank and the inner wall of the partition, thereby removing impurities adhering to the coagulation tank, magnetic tank, flocculation tank and partition, reducing the time for subsequent manual cleaning by personnel.

[0020] 3. In the actual operation of the present invention, by starting multiple second motors, the multiple second motors are made to rotate the corresponding inclined filter plates at the same angle, so that the rotation angles of the multiple inclined filter plates are consistent. The sewage entering the sedimentation tank from the flocculation tank will settle and stratify under the action of gravity, and the arranged inclined filter plates are used to separate the sediment and the supernatant, preventing large or long substances that cannot be flocculated and precipitated in the sewage from floating into the supernatant. In addition, two adjacent inclined filter plates rotate relative to each other, which can change the angle between the two adjacent inclined filter plates, thereby adapting to the size of the impurities intercepted in the actual sedimentation.

[0021] 4. In the actual operation of the present invention, after the cleaning cloths on the outside of the multiple square frames scrape off the sludge inside the corresponding coagulation tank, magnetic tank, and flocculation tank, the sludge can be discharged from the discharge port by opening the solenoid valve, and discharged to the outside under the action of the pump body to reduce the accumulation of impurities. The sludge in the sedimentation tank and coagulation tank, magnetic tank, and flocculation tank is discharged through the same pump body, without the need for additional equipment, thereby reducing costs.

[0031] Reference Figure 1 , Figure 2 As shown, the coagulation tank 3, the magnetic tank 4, the flocculation tank 5 and the sedimentation tank 6 are separated by three partitions 14, and the three partitions 14 are staggered up and down.

[0032] The three partitions 14 are respectively used to be fixed between the coagulation tank 3 and the magnetic tank 4, between the magnetic tank 4 and the flocculation tank 5, and between the flocculation tank 5 and the sedimentation tank 6. The top of the partition 14 between the coagulation tank 3 and the magnetic tank 4 is flush with the top of the clarification tank 1, and the bottom of the partition 14 between the magnetic tank 4 and the flocculation tank 5 is flush with the bottom of the clarification tank 1, and so on, so that the coagulation tank 3, the magnetic tank 4, the flocculation tank 5 and the sedimentation tank 6 are connected to form an S-shaped channel. The input sewage can flow through the S-shaped channel, extending the flow path, increasing the flow time, and facilitating coagulation and separation of sludge.

[0033] Reference Figure 2As shown, a movable groove 17 is opened on one side of the coagulation tank 3, the magnetic tank 4 and the flocculation tank 5, and a screw 18 is rotatably connected between the upper and lower ends of the movable groove 17. The outer sides of the three screws 18 are threadedly matched with sliding blocks 19, and a square frame 27 is fixed on one side of the three sliding blocks 19. A filter screen 16 is fixed in the center of the three square frames 27. The three square frames 27 are respectively lifted and slid in the coagulation tank 3, the magnetic tank 4 and the flocculation tank 5. A first motor 7 is fixed on one side of the top of the coagulation tank 3, the magnetic tank 4 and the flocculation tank 5, and the driving shafts of the three first motors 7 are fixedly connected to one end of the corresponding screw 18.

[0034] In the actual operation of the present invention, by starting the three first motors 7, the three first motors 7 can respectively drive the corresponding screws 18 to rotate, and the rotation of the screws 18 drives the corresponding square frames 27 to move up and down. When the square frame 27 moves to the connecting point between the corresponding coagulation tank 3, the magnetic tank 4, and the flocculation tank 5, the connecting point can be blocked so that the coagulation tank 3, the magnetic tank 4, and the flocculation tank 5 each form a closed area, so that the sewage inside the coagulation tank 3, the magnetic tank 4, and the flocculation tank 5 can react separately.

In addition, when the square frame 27 moves up and down, the cleaning cloth on the outside of the square frame 27 can rub against the corresponding coagulation tank 3, magnetic tank 4, flocculation tank 5 and the inner wall of the partition 14, thereby removing impurities adhering to the coagulation tank 3, magnetic tank 4, flocculation tank 5 and partition 14, thereby reducing the time for subsequent manual cleaning by personnel.

[0041] In the actual operation of the present invention, by starting multiple second motors 12, multiple second motors 12 are made to rotate the corresponding inclined filter plates 13 at the same angle, so that the rotation angles of multiple inclined filter plates 13 are consistent, and the sewage entering the sedimentation tank 6 from the flocculation tank 5 will settle and stratify under the action of gravity, and the arranged inclined filter plates 13 are used to separate the sediment and the supernatant, preventing large or long substances that cannot be flocculated and precipitated in the sewage from floating into the supernatant, and two adjacent inclined filter plates 13 rotate relative to each other, which can change the angle between the two adjacent inclined filter plates 13, thereby adapting to the size of the impurities intercepted in the actual sedimentation.
