The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1-5 , is the first embodiment of the utility model, which provides an integrated high-efficiency denitrification and dephosphorization filtering device, including:

[0030] The pretreatment component 100 includes a bracket 101, an anoxic tank 102 installed at one end of the bracket 101, an anaerobic tank 103 installed in the middle of the bracket 101, and a sedimentation tank 104 installed at the other end of the bracket 101. The anoxic tank 102 is connected to the inside of the anaerobic tank 103, an aerobic tank 105 is installed on one side of the anaerobic tank 103, the upper end outlet of the anaerobic tank 103 is connected to the inlet of the aerobic tank 105, and one side of the aerobic tank 105 is connected to the sedimentation tank 104 through a pipeline.

[0031] The pretreatment assembly 100, consisting of an anoxic tank 102, an anaerobic tank 103, a sedimentation tank 104, and an aerobic tank 105, is used to remove nitrogen and phosphorus from the sewage. The sewage enters the anoxic tank 102, where denitrification occurs, and then enters the anaerobic tank 103, where phosphorus is released by phosphate-accumulating bacteria. The phosphate-accumulating bacteria obtain energy by decomposing polyphosphates in their bodies, absorb volatile fatty acids in the water, and convert the volatile fatty acids into polyphosphates. The nitrate nitrogen is stored in the body in the form of β-hydroxybutyric acid, and phosphorus is released into the water. The liquid carrying nitrate nitrogen returned from the aerobic tank 105 is mixed with the sewage returned from the anaerobic tank 103. The denitrifying bacteria reduce the nitrate nitrogen to N2, and the N2 escapes into the air. Then the sewage enters the aerobic tank 105. In the aerobic tank 105, the main activities are organic matter removal and nitrification. Aerobic bacteria remove organic matter in the water, and nitrifying bacteria nitrify ammonia nitrogen in the water. The sewage is precipitated in the sedimentation tank 104 and then discharged.

[0032] Specifically, matching return pipes 106 are installed at the bottom of the anoxic tank 102 , the anaerobic tank 103 , the sedimentation tank 104 and the aerobic tank 105 . A return pool 107 is provided on one side of the bracket 101 , and the end of the return pipe 106 is encapsulated on the inner wall of the return pool 107 .

[0033] Among them, a return pipe 106 is added to connect with the anoxic tank 102, the anaerobic tank 103, the sedimentation tank 104 and the aerobic tank 105 respectively, so as to facilitate the return of the incompletely reacted nitrification liquid and part of the sludge, and start the operation again from the anoxic tank 102. The sludge is returned to the anaerobic tank 103 to maintain the concentration of the system sludge, and the sewage is denitrified and dephosphorized to improve the phosphorus removal effect.

[0034] Furthermore, a partition 108 is installed on the inner side wall of the sedimentation tank 104, and a through-hole structure is opened on the side wall of the partition 108 at equal intervals. A drainage pipe 109 is installed at one end of the sedimentation tank 104, and the drainage pipe 109 is connected to the middle groove of the partition 108.

[0035] Among them, a partition 108 is installed above the beam 201 inside the sedimentation tank 104, and a through-hole structure is added to the side wall of the partition 108 to facilitate the precipitated liquid to enter the middle of the partition 108 from the through-hole, and then flow into the drainage pipe 109 and be transported backward, intercepting large particles of floating objects outside the partition 108.

[0036] During use, the sewage enters the anoxic tank 102, where denitrification reaction mainly takes place, and then enters the anaerobic tank 103. In the anaerobic tank 103, polyphosphate bacteria mainly release phosphorus. Polyphosphate bacteria obtain energy by decomposing polyphosphates in their bodies, absorb volatile fatty acids in the water, and store volatile fatty acids in the body in the form of poly-β-hydroxybutyric acid, while releasing phosphorus into the water. The liquid carrying nitrate nitrogen returned from the aerobic tank 105 is mixed with the sewage returned from the anaerobic tank 103. The denitrifying bacteria reduce the nitrate nitrogen to N2, which escapes into the air. Then the sewage enters the aerobic tank 105, where organic matter removal and nitrification reaction mainly take place. Aerobic bacteria remove organic matter in the water, and nitrifying bacteria nitrify ammonia nitrogen in the water. The sewage is precipitated in the sedimentation tank 104 and then discharged.

[0037] In summary, the pretreatment assembly 100 consisting of the anoxic tank 102, the anaerobic tank 103, the sedimentation tank 104 and the aerobic tank 105 is used to remove nitrogen and phosphorus from the sewage. Aerobic bacteria remove organic matter in the water, and nitrifying bacteria nitrify ammonia nitrogen in the water. The sewage is precipitated in the sedimentation tank 104 and then discharged. The return pipe 106 is added to connect with the anoxic tank 102, the anaerobic tank 103, the sedimentation tank 104 and the aerobic tank 105 respectively to facilitate the return of the unreacted nitrified liquid and part of the sludge to the sewage. The sludge is returned to the anaerobic tank 103 to maintain the concentration of the sludge in the system, and the sewage is denitrified and dephosphorized to improve the dephosphorization effect. A partition 108 is installed above the beam 201 in the sedimentation tank 104. A through-hole structure is added to the side wall of the partition 108 to facilitate the precipitated liquid to enter the middle of the partition 108 from the through-hole, and then flow into the drainage pipe 109 for backward transportation, thereby intercepting large particles of floating objects outside the partition 108.

[0038] Example 2

[0039] Reference Figure 1-5 This is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a precipitation component 200 of an integrated high-efficiency denitrification and dephosphorization filtration device.

[0040] The sedimentation assembly 200 includes a beam 201, a sliding member 202 movably installed in the middle of the beam 201, a connecting rod 203 rotatably installed on the side wall of the sliding member 202, and a filler 204 installed on the side wall of the connecting rod 203. The end of the beam 201 is connected to the inner wall of the sedimentation tank 104 by bolts.

[0041] Among them, a sedimentation component 200 consisting of a beam 201, a sliding member 202, a connecting rod 203 and a filler 204 is added to assist the sedimentation tank 104 in sedimentation and filtration treatment of sewage. The beam 201 is docked with the sedimentation tank 104 and is used to install the sliding member 202 with the filler 204 and the connecting rod 203. By adjusting the position of the sliding member 202 along the beam 201, the position of the filler 204 installed at the end of the connecting rod 203 can be adjusted to perform adsorption and sedimentation treatment on the sewage inside the sedimentation tank 104, thereby improving the sedimentation and purification efficiency of the sewage. In addition, by adjusting the position of the sliding member 202 along the beam 201, the spacing between the fillers 204 installed at the end of the connecting rod 203 can be changed to adapt to the installation and use of fillers 204 of different specifications.

[0042] Specifically, the side wall of the sliding member 202 is provided with a latch hole structure at equal intervals, a latch rod 205 is inserted in the middle of the latch hole on the side wall of the sliding member 202, a through hole matching the latch rod 205 is opened on the side wall of the connecting rod 203, and the end of the latch rod 205 passes through the side wall of the sliding member 202 and is inserted into the through hole on the side wall of the connecting rod 203.

[0043] Among them, the latch rod 205 is installed on the side wall of the sliding part 202 to connect with the connecting rod 203, so that the connecting rod 203 can be installed on the side wall of the sliding part 202 at different angles, which facilitates the adjustment and maintenance of the filler 204 installed on the side wall of the sliding part 202.

[0044] Furthermore, a curved rod 206 is inserted into one side of the sliding member 202 , and the end of the curved rod 206 is threadedly connected to a double screw sleeve 207 , and the end of the double screw sleeve 207 is threadedly connected to the end of another set of curved rods 206 .

[0045] Among them, a bent rod 206 connected by a double screw sleeve 207 is installed on the side wall of the sliding part 202. Rotating the double screw sleeve 207 can adjust the distance between the bent rods 206 connected to the side walls of the two groups of sliding parts 202, and then adjust the distance between the two groups of sliding parts 202 to adapt to different usage requirements.

[0046] Furthermore, a collar 208 is movably mounted on the side wall of the connecting rod 203 , and an end of the filler 204 is fixedly mounted on the side wall of the collar 208 .

[0047] Among them, the collar 208 is installed on the side wall of the connecting rod 203, which is convenient for installing the filler 204 and adjusting the installation position of the filler 204 along the connecting rod 203, so as to adapt to the installation and use of fillers 204 of different specifications.

[0048] Preferably, a tension spring 209 is connected to one side of the upper end of the collar 208 via a bolt, and the upper end of the tension spring 209 is fixedly mounted on the side wall of the connecting rod 203 .

[0049] Among them, a tension spring 209 is added to the ring 208. The tension spring 209 can provide a certain tension for the ring 208 on the basis of the connection of the connecting rod 203 to maintain the stability of the position of the ring 208. When the ring 208 moves down a certain distance due to the filler 204 adsorbing too many impurities, the tension spring 209 can pull the ring 208 to move upward, so that the precipitated sewage is flushed on the surface of the filler 204, the surface of the filler 204 is cleaned, and the self-cleaning process is completed.

[0050] In summary, a sedimentation assembly 200 consisting of a crossbeam 201, a sliding member 202, a connecting rod 203 and a filler 204 is added to assist the sedimentation tank 104 in sedimentation and filtration treatment of sewage. The crossbeam 201 is docked with the sedimentation tank 104 and is used to install the sliding member 202 with the filler 204 and the connecting rod 203. By adjusting the position of the sliding member 202 along the crossbeam 201, the position of the filler 204 installed at the end of the connecting rod 203 can be adjusted to perform adsorption and sedimentation treatment on the sewage inside the sedimentation tank 104, thereby improving the sedimentation and purification efficiency of the sewage. The position of the connecting rod 203 can change the spacing of the filler 204 installed at the end thereof, and adapt to the installation and use of fillers 204 of different specifications. A tension spring 209 is added to the collar 208. The tension spring 209 can provide a certain pulling force for the collar 208 on the basis of the connection of the connecting rod 203, so as to maintain the stability of the position of the collar 208. When the collar 208 moves down a certain distance due to too many impurities adsorbed by the filler 204, the tension spring 209 can pull the collar 208 to move upward, so that the precipitated sewage is washed on the surface of the filler 204, and the surface of the filler 204 is cleaned, completing the self-cleaning process.
