Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a biodegradation treatment device for a sedimentation tank of a waterworks. Background Art

[0002] The sedimentation tank of a waterworks usually uses the method of biodegradation to effectively remove organic substances and suspended solids in water, ensuring the safety of water quality. During the process of biodegradation, a carbon source needs to be added to promote the activity during biodegradation.

[0003] According to the "biodegradation treatment device for a sedimentation tank of a waterworks" with the Chinese patent publication number CN218879598U, it mainly describes that biodegradation is carried out by using suspended packing to improve the treatment efficiency of removing indicators such as ammonia nitrogen and organic matter in tap water. A interception net is used to prevent the loss of suspended packing. This technical solution can make full use of existing structures such as the sedimentation tank of a waterworks without the need to build new structures. Only two water tanks need to be retrofitted to improve the effect of biodegradation. In addition, by setting the flow rate of inlet and outlet water, the reasonable residence time in the process of tap water treatment is controlled, and the oxygen content introduced into the biodegradation tank by the air diffuser is controlled, so as to control the air-water ratio, and then effectively strengthen the removal of ammonia nitrogen and organic matter in water. During this process, the suspended packing is arranged on the upper side of the large sedimentation tank, which will block the spraying of the carbon source, resulting in the influence on the activity of organisms.

[0004] Therefore, a biodegradation treatment device for a sedimentation tank of a waterworks is proposed to solve the problem that during this process, the suspended packing arranged on the upper side of the large sedimentation tank will block the spraying of the carbon source, resulting in the influence on the activity of organisms.

Specific embodiments

[0016] The present utility model will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1-3 A biodegradation treatment device for a sedimentation tank in a waterworks as shown, which includes a reaction tank 1 and a clear water tank 2. An inner tank 3 is fixedly connected inside the reaction tank 1. Grilles 4 are uniformly fixedly connected to the upper end of the inner tank 3. After the water body is treated in the inner tank 3, it enters the reaction tank 1 through the grilles 4 and then enters the clear water tank 2. A return guide groove 5 is opened on the upper side of the inner tank 3. A moving frame 6 is arranged on the upper side of the inner tank 3. Pulley 7 is rotatably connected to each of the four sides of the bottom end of the moving frame 6. The moving frame 6 moves in the return guide groove 5 through the pulley 7. The pulley 7 is in contact with the return guide groove 5. An open groove 8 is opened on the upper side of the moving frame 6. A driving motor (the driving motor is not shown in the figure and only serves as a power source for driving the moving frame 6 to move) is fixedly connected to one side of the moving frame 6, and the output end of the driving motor is fixedly connected to a first screw 9. The driving motor rotates to drive the first screw 9 to rotate and makes the moving block 10 move. At this time, the moving frame 6 moves horizontally in the inner tank 3. A moving block 10 is threadedly connected to the first screw 9. A conduit 11 is fixedly connected to the upper end of the moving block 10. A feeding chute 12 is fixedly connected to the upper end of the conduit 11. A hose 13 is fixedly connected to the bottom end of the moving block 10, and an output pipe 14 is fixedly connected to the bottom end of the hose 13. A spray head 15 is fixedly connected to the bottom end of the output pipe 14. A water pump is arranged on the conduit 11 to extract the carbon source in the feeding chute 12 into the conduit 11, transfer it to the output pipe 14 through the hose 13, and then make the carbon source mix with the water body in the sedimentation tank through the spray head 15, thereby promoting the activity of microorganisms and improving the degradation efficiency of microorganisms.

[0018] Among them, the output pipe 14 is fixedly connected to the pressing plate 18. A second screw rod 17 is threadedly connected to the pressing plate 18. The second screw rod 17 is fixedly connected to the output end of the driving motor. The driving motor is fixedly connected to the upper end of the moving block 10. The bottom end of the moving block 10 is fixedly connected with a bracket, and the bracket is fixedly connected to the upper end of the connecting plate 16. The connecting plate 16 is located outside the output pipe 14. By driving the second screw rod 17 to rotate through the driving motor, the pressing plate 18 and the output pipe 14 can be moved downward. At this time, the spray head 15 can move in the inner pool 3.

[0019] Among them, the output pipe 14 is in contact with the rubber ring 22. The rubber ring 22 is fixedly connected in the circular groove. The circular groove is located in the connecting plate 16. By providing the rubber ring 22, the entry of water into the space between the moving block 10 and the connecting plate 16 can be reduced when the output pipe 14 moves up and down.

[0020] Among them, the moving block 10 is fixedly connected to the upper end of the folding cover 21. The folding cover 21 is fixedly connected to the upper end of the connecting plate 16. By providing the folding cover 21, the contact between the water and the second screw rod 17 is avoided, so that the movement of the pressing plate 18 is smoother.

[0021] Among them, the moving frame 6 is in contact with the spherical ball 20. The spherical ball 20 is rotatably embedded in the bottom end of the support frame 19. The support frame 19 is fixedly connected to the four sides of the bottom end of the feeding chute 12. By providing the support frame 19 and the spherical ball 20, the stability of the feeding chute 12 during movement can be improved.

[0022] Working principle: Water enters the inner pool 3 from the upper side of the inner pool 3. At this time, the pulley 7 can be rotated manually or by mechanical equipment, and the moving frame 6 can be moved horizontally. Then, the driving motor is started to drive the first screw rod 9 to rotate and the moving block 10 to move horizontally, so that the carbon source in the feeding chute 12 can move above the inner pool 3. At this time, the water pump extracts the carbon source from the conduit 11, and reaches the spray head 15 through the hose 13 and the output pipe 14. At the same time, the second screw rod 17 rotates to move the pressing plate 18 and the output pipe 14 downward, which can change the depth of the spray head 15, promote the mixing of the carbon source and the water, and provide nutrients for the microorganisms, so as to improve the activity of the microorganisms during degradation.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.

[0024] The other parts not described in detail in the present invention all belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
