Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and particularly relates to a potential energy biological sewage purifier. Background Art

[0002] At present, the main deep biological treatment technology for sewage at home and abroad combines activated sludge and biological contact oxidation processes, aiming to make the treated water quality meet the standards of reclaimed water. However, in this sewage treatment technology, the aerobic process mostly uses the method of blowing aeration, resulting in low reoxygenation efficiency, high energy consumption, and high operating costs. Chinese Patent with the application number CN200520071365.X discloses a potential energy oxygenation ecological bed, in which the oxygenator is arranged at one end of the ecological riverbed or turf, and the other end of the ecological riverbed or turf is a water tank for receiving the sewage inlet pump pipe or a water tank for receiving the water outlet of the upper layer of oxygenator. The siphon water suction port is arranged at the lower inlet of the oxygenator, making full use of the effective head of the water pump, converting potential energy into kinetic energy through siphon for large oxygen reoxygenation and stripping. Although it can reduce aeration energy consumption, there are defects such as short residence time of sewage on each ecological bed, poor sewage treatment effect, relatively high energy consumption, and easy breeding of mosquitoes and flies around the biological disk.

[0003] Therefore, it is necessary to improve the existing sewage treatment device in order to solve the above problems. Summary of the Invention

The lower surface of the bottom plate 8-4 of the purifier box body water outlet groove is provided with a purifier box body water outlet bottom plate reinforcing rib 8-5 perpendicular to the extending direction of the purifier box body water spraying long holes 8-6. The purifier box body water outlet bottom plate reinforcing rib 8-5 is used to strengthen the strength of the bottom plate 8-4 of the purifier box body water outlet groove and prevent the bottom plate 8-4 of the purifier box body water outlet groove from deforming due to long-term use;

[0056] As Figure 2-3 shown, a bacteria bed 6 and a bacteria bed fixing frame assembly 7 are provided in the second zone 4-2 of the purifier box body of each layer of the potential energy biological sewage purification box body;

[0057] The bacteria bed 6 is a number of rectangular plate-like shapes arranged side by side. The bacteria bed 6 extends in the front-rear direction, and there are gaps between the bacteria beds 6. The bacteria bed 6 has a pore structure. The specific surface area range of the bacteria bed 6 is 1000-6000. The bacteria bed 6 is a carrier for biological bacteria and is used to reduce COD, BOD, and N-NH3 in sewage and further improve the denitrification and phosphorus removal efficiency;

[0058] The bacteria bed fixing frame assembly 7 includes a bacteria bed hook fixing frame 7-1 clamped to the bottom end of the bacteria bed 6, a bacteria bed straight hook blocking frame 7-2 provided on one side of the bacteria bed hook fixing frame 7-1, and a bacteria bed fixing frame plate 7-3 provided at the bottom end of the bacteria bed hook fixing frame 7-1. The bottom end of the bacteria bed fixing frame plate 7-3 is detachably connected to the second zone 4-2 of the purifier box body; the bacteria bed 6 is fixed on the upper surface of the second zone 4-2 of the purifier box body through the bacteria bed fixing frame assembly 7.

[0059] AsFigure 2-3 As shown in the figure, a delay box assembly 9 is provided in the first - stage potential energy biological sewage purification box body 1 (odd - stage potential energy biological sewage purification box body). The delay box assembly 9 is located above the floating box assembly 3 of the lower - stage potential energy biological sewage purification box body;

[0060] The delay box assembly 9 includes a delay box 9 - 2 and a delay drain pipe 9 - 7 arranged on one side of the delay box 9 - 2. The bottom end of the delay box 9 - 2 is fixed on the upper surface of the first - stage purification box area 4 - 1 of the purifier box body through a bracket. The delay drain pipe 9 - 7 is fixed on the upper surface of the first - stage purification box area 4 - 1 of the purifier box body, and a through - hole is provided at the position corresponding to the delay drain pipe 9 - 7 on the first - stage purification box area 4 - 1 of the purifier box body;

[0061] The top end of the delay box 9 - 2 is open, and a delay float 9 - 1 is provided inside the delay box 9 - 2. One side of the delay float 9 - 1 is hinged to the opening at the top end of the delay box 9 - 2. A pull - rod assembly 9 - 5 is provided at the top end of the delay float 9 - 1, and a delay ball 9 - 6 is provided at the end of the pull - rod assembly 9 - 5. The delay ball 9 - 6 is located above the delay drain pipe 9 - 7. A delay - box water outlet 9 - 3 is provided on the bottom plate of the delay box 9 - 2, and a sealing float 9 - 4 is provided at the delay - box water outlet 9 - 3. Through the action of water buoyancy, the delay ball 9 - 6 periodically opens and closes the delay drain pipe 9 - 7.

[0062] When sewage flows into the first - stage potential energy biological sewage purification box body 1 (odd - stage potential energy biological sewage purification box body), as the water level rises, the sealing float 9 - 4 rises to block the delay - box water outlet 9 - 3. Subsequently, the sewage flows into the floating box assembly 3 of the next layer through the delay drain pipe 9 - 7. As the water level rises, the sewage flows into the delay box 9 - 2. The delay float 9 - 1 moves upward under the action of water buoyancy, and the delay float 9 - 1 rotates to move the delay ball 9 - 6 on the pull - rod assembly 9 - 5 downward to block the delay drain pipe 9 - 7. When the first - stage potential energy biological sewage purification box body 1 (odd - stage potential energy biological sewage purification box body) discharges sewage from the full state, as the water level drops, the delay float 9 - 1 seals the drain pipe 9 - 7 under the action of the sewage buoyancy in the delay box 9 - 2. As the water level moves downward, the sealing float 9 - 4 moves downward to open the delay - box water outlet 9 - 3, the sewage in the delay box is discharged, the delay float 9 - 1 moves downward, and the delay float 9 - 1 rotates to move the delay ball 9 - 6 on the pull - rod assembly 9 - 5 upward to open the delay drain pipe 9 - 7.

[0063] Each layer of potential energy biological sewage purification box body can be designed with a delay of 3 - 30 minutes according to needs.

[0064] The water inlet between adjacent - layer potential energy biological sewage purification box bodies is controlled by the floating box assembly 3 of the adjacent layer; the water outlet of the purifier box body assembly 8 is controlled by the delay box assembly 9 of the adjacent layer acting on the floating box assembly 3 of this layer.

[0065] Each layer of the potential energy biological sewage purification box is arranged in a front-to-back staggered manner, so as to facilitate the removal, filling and cleaning of the mushroom bed 6. In addition to the aforementioned method of fixing the mushroom bed 6 on the upper surface of the purifier box second area 4-2 of the potential energy biological sewage purification box of the current layer by using the mushroom bed fixing frame assembly 7, the mushroom bed 6 can also be hung on the lower bottom surface of the upper layer of the potential energy biological sewage purification box, or the mushroom bed 6 can be hung on the side end of the potential energy biological sewage purification box of the current layer.

[0066] like Figure 6 As shown, the bottom of the purifier box zone 1 4-1 of the first layer potential energy biological sewage purification box 1 (odd-numbered layer potential energy biological sewage purification box) corresponds to the purifier box zone 3 of the second layer potential energy biological sewage purification box 2 (even-numbered layer potential energy biological sewage purification box) and is also provided with a lower water control mechanism;

[0067] The lower water control mechanism comprises a sealing ball leakage pipe 10-3 arranged at the bottom of the first potential energy biological sewage purification box 1 purifier box area 4-1, the bottom end of the sealing ball leakage pipe 10-3 is provided with a three-way pipe 10-4 connected to the sealing ball leakage pipe 10-3, and the branch of the three-way pipe 10-4 is connected with a three-way outlet pipe 10-5; a sealing ball connecting rod 10-2 is passed through the sealing ball leakage pipe 10-3, and the top of the sealing ball connecting rod 10-2 is upwardly passed through the sealing ball leakage pipe 10-3, and the top of the sealing ball connecting rod 10-2 is provided with a sealing ball 10-1, The bottom end of the ball connecting rod 10-2 passes downward through the sealing ball leakage pipe 10-3 and the three-way pipe fitting 10-4 in sequence, and passes through the bottom outlet of the three-way pipe fitting 10-4. A sealing ball control float 10-6 is provided at the bottom end of the sealing ball connecting rod 10-2. The sealing ball 10-1 is located in the purifier box zone 1 4-1 of the first potential energy biological sewage purification box 1, and the sealing ball control float 10-6 is located in the purifier box zone 3 of the second potential energy biological sewage purification box 2, and the water outlet end of the three-way outlet pipe 10-5 extends into the purifier box zone 3 of the second potential energy biological sewage purification box 2.

[0068] The blocking ball connecting rod 10-2 can move downward in the three-way pipe fitting 10-4 with the buoyancy of the blocking ball control float 10-6, and when there is no water in the purifier box area 1 of the first layer of potential energy biological sewage purification box 1, the blocking ball 10-1 blocks the blocking ball leakage pipe 10-3 downward due to gravity. By arranging a lower layer water control mechanism at the bottom of the purifier box area 1 of the first layer of potential energy biological sewage purification box 1, it is possible to achieve a mode in which the lower layer of potential energy biological sewage purification box between two adjacent layers of potential energy biological sewage purification boxes controls the water inlet and outlet of the upper layer of potential energy biological sewage purification box.

[0069] Operating principle: Sewage flows into the first - layer potential - energy biological sewage purification box body area 4 - 1 on the left side of the first - layer potential - energy biological sewage purification box body 1 (odd - numbered layer potential - energy biological sewage purification box body) through the water - inlet device of the potential - energy biological sewage purifier. Figure 1 As shown, the sewage flows through the first - layer potential - energy biological sewage purification box body area 4 - 1, the water - retaining plate assembly 5, the second - layer potential - energy biological sewage purification box body area 4 - 2, several groups of bacterial beds 6 in the second - layer potential - energy biological sewage purification box body area 4 - 2, the water - retaining plate assembly 5, and the third - layer potential - energy biological sewage purification box body area 4 - 3 in sequence.

[0070] As the water continuously flows into the first - layer potential - energy biological sewage purification box body area 4 - 1 of the first - layer potential - energy biological sewage purification box body 1, the water level in the first - layer potential - energy biological sewage purification box body 1 rises. The plugging float 9 - 4 of the delay - box assembly 9 rises to plug the delay - box water outlet 9 - 3, and the sewage enters the delay - box 9 - 2. The delay float 9 - 1 seals the leakage water pipe 9 - 7 under the buoyancy of the sewage in the delay - box 9 - 2.

[0071] The water level in the first - layer potential - energy biological sewage purification box body 1 continues to rise. The floating - box water - stop ball 3 - 6 of the floating - box assembly 3 floats up with the floating - box water - stop float 3 - 7 to plug the floating - box water outlet 3 - 8.

[0072] The water level in the first - layer potential - energy biological sewage purification box body 1 continues to rise. The sewage enters the floating box body 3 - 4 of the floating - box assembly 3. As the water level in the floating box body 3 - 4 rises, the float 3 - 3 rises along the guide pipe, and at the same time drives the purification - box body water - sealing plate 8 - 2 to rise, opening the purification - box body water outlet 8 - 3. The sewage in the first - layer potential - energy biological sewage purification box body 1 (odd - numbered layer potential - energy biological sewage purification box body) flows through the purification - box body water outlet 8 - 3, through the water - spraying long hole 8 - 6 of the purification box body, increasing the dissolved oxygen by means of water spraying until the DO reaches 6mg / L, and the sewage flows into the first - layer potential - energy biological sewage purification box body area 4 - 1 on the right side of the second - layer potential - energy biological sewage purification box body 2 (even - numbered layer potential - energy biological sewage purification box body).

[0073] As the water level in the first - layer potential - energy biological sewage purification box body 1 drops, the plugging float 9 - 4 moves down to open the delay - box water outlet 9 - 3, and the sewage in the delay - box 9 - 2 is discharged. The delay float 9 - 1 rotates to make the delay ball 9 - 6 on the pull - rod assembly 9 - 5 move up, allowing the sewage to flow into the floating - box assembly 3 in the second - layer potential - energy biological sewage purification box body 2. As the water level in the floating box body 3 - 4 rises, the float 3 - 3 rises along the guide pipe, and at the same time drives the purification - box body water - sealing plate 8 - 2 to rise, opening the purification - box body water outlet 8 - 3. The sewage in the first - layer potential - energy biological sewage purification box body 1 flows through the purification - box body water outlet 8 - 3, through the water - spraying long hole 8 - 6 of the purification box body for water spraying, thereby controlling the water discharge of the purification - box body water outlet 8 - 3 in the second - layer potential - energy biological sewage purification box body.

[0074] The water level in the first-layer potential energy biological sewage purification box body 1 continues to drop. The floating box water-stop float 3-7 drives the floating box water-stop ball 3-6 to descend and open the sealed floating box water outlet 3-8, allowing the sewage in the floating box body 3-4 of the floating box assembly 3 to be discharged from the floating box water outlet 3-8 into the third area 4-3 of the purifier box body in the first-layer potential energy biological sewage purification box body 1, and then flowing into the first area 4-1 of the purifier box body in the second-layer potential energy biological sewage purification box body 2 through the purifier box body water outlet 8-3 and the purifier box body water spraying long hole 8-6. The sewage then enters the third-layer potential energy biological sewage purification box body in the same way through the second-layer potential energy biological sewage purification box body, and finally flows through each layer of potential energy biological sewage purification box bodies in sequence.

[0075] Furthermore, between adjacent layers of potential energy biological sewage purification box bodies, it is possible to achieve the lower-layer potential energy biological sewage purification box body controlling the water inlet and outlet of the upper-layer potential energy biological sewage purification box body. Specifically:

[0076] When a large amount of water starts to be injected from the upper-layer potential energy biological sewage purification box body into the lower-layer potential energy biological sewage purification box body through the purifier box body water spraying long hole 8-6, the plugging ball 10-1 closes the plugging ball drain pipe 10-3 by its own weight. As the water level in the lower-layer potential energy biological sewage purification box body rises, the plugging ball control float 10-6 is affected by the buoyancy force, thereby driving the plugging ball 10-1 to open the plugging ball drain pipe 10-3. The upper-layer potential energy biological sewage purification box body starts to slowly inject water into the floating box body 3-4 of the floating box assembly in the lower-layer potential energy biological sewage purification box body through the plugging ball drain pipe 10-3. At this time, a large amount of water is injected from the upper-layer potential energy biological sewage purification box body into the lower-layer upper-layer potential energy biological sewage purification box body through the water spraying long hole 8-6, and at the same time, the upper-layer potential energy biological sewage purification box body slowly injects water into the floating box body 3-4 of the floating box assembly in the lower-layer upper-layer potential energy biological sewage purification box body through the plugging ball drain pipe 10-3. The above two water injection methods have a time difference that needs to be controlled in the process design requirements, and this time difference can be adjusted by changing the relative position of the plugging ball control float 10-6 fixed at the lower end of the plugging ball connecting rod 10-2.

[0077] When the water level in the floating box body 3-4 of the floating box assembly in the lower-layer potential energy biological sewage purification box body rises to the set height, the float 3-3 rises along the guide pipe, and at the same time drives the purifier box body water outlet sealing plate 8-2 to rise, opening the purifier box body water outlet 8-3. The sewage in the potential energy biological sewage purification box body 1 passes through the purifier box body water outlet 8-3 and flows into the lower-layer potential energy biological sewage purifier from the purifier box body water spraying long hole 8-6.
