Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an AO type integrated sewage treatment device and a treatment method. Background Art

[0002] The AO sewage treatment process is a biological treatment technology that achieves nitrogen and phosphorus removal and organic matter degradation through anaerobic and aerobic two-stage treatment. Its core process includes anaerobic and aerobic sections. The anaerobic bacteria in the anaerobic section decompose large molecular organic matter into small molecules (such as organic acids), while polyphosphate-accumulating bacteria release phosphorus. The sewage then enters the aerobic section, where aerobic microorganisms degrade organic matter into carbon dioxide and water, and nitrifying bacteria oxidize ammonia nitrogen into nitrates. The sewage is then sent back to the anaerobic section, and this process is repeated many times to purify the sewage.

[0003] China's public patent, publication number CN117964113B, discloses a two-stage AO denitrification and phosphorus removal sewage treatment equipment.

[0004] In the prior art, including the above-mentioned patents, during the sewage treatment process, the microorganisms of the treatment system are easily carried away by the sewage, especially in the aerobic section. In order to ensure the dissolved oxygen content in the aerobic section, it is necessary to install aeration equipment at the bottom of the pool to blow air into the sewage. This causes the sewage in this section to be very active, and the sludge and filler are also pushed by the water flow. The microorganisms on the sludge and filler are easily thrown off and enter the anaerobic section or are discharged with the sewage, which leads to serious loss of microorganisms in the aerobic section. Summary of the Invention

[0005] The purpose of the present invention is to provide an AO type integrated sewage treatment equipment and treatment method, aiming to solve the above problems.

[0006] In order to achieve the above-mentioned object, the present invention provides an AO type integrated sewage treatment equipment, including a treatment tank, wherein the treatment tank is provided with:

[0007] A fixed block having an isosceles triangle cross section;

[0008] A mounting block having a right triangle cross section;

[0009] A partition is movably mounted inside the treatment tank and cooperates with the fixed block and the mounting block to form a first flow channel in the shape of a >. The partition is movably provided with a plurality of flaps facing the aeration ports inside the treatment tank, wherein:

[0010] The flap is turned over to allow substances to be exchanged between the two sides of the partition, and the partition moves to a horizontal state to horizontally separate the treatment pool.

[0011] Preferably, a receiving groove and a receiving groove are respectively provided at the bottom and the top of the partition, and a blocking piece in a vertical state in the first flow channel is provided inside the receiving groove.

[0012] Preferably, a rotating shaft for separating the receiving groove and the receiving groove is provided on the partition, and the rotating shaft is eccentrically arranged.

[0013] Preferably, the receiving groove is located on a larger side of the partition separated by the rotating shaft and faces the aeration port.

[0014] Preferably, a plurality of movable bars are movably provided in the partition, and the partition is moved to a horizontal state so that the movable bars are embedded in the flap.

[0015] Preferably, the fixing block is provided with a vertical second flow channel and a first baffle and a second baffle for blocking both ends of the second flow channel.

[0016] Preferably, the partition moves to a horizontal position so that the first baffle and the second baffle respectively block both ends of the first flow channel.

[0017] Preferably, the partition and the mounting block are respectively provided with a first attachment block and a second attachment block for supporting microorganisms, and the inclined ends of the first attachment block and the second attachment block are respectively used to support the first baffle and the second baffle.

[0018] Preferably, the cross section of the first attachment block is an isosceles triangle and a flap is movably provided between two adjacent first attachment blocks.

[0019] A novel AO-type integrated sewage treatment method includes the AO-type integrated sewage treatment equipment in the above scheme, and further includes the following steps:

[0020] S1. Sewage enters the treatment tank and flows along the first flow channel of the >-shape, and comes into contact with microorganisms attached to the partition, fixed block, and mounting block;

[0021] S2. The flap receives the impurities decomposed by microorganisms, and the aeration port aerates intermittently, pushing the flap to flip, causing air to move upward and impurities on the flap to move downward;

[0022] S3. After working for a period of time, the partition is driven to a horizontal state to separate the treatment pool, and the first flow channel is closed and the second flow channel is in operation;

[0023] S4. The sludge under the partition is pumped away, and the partition is driven to become an inclined state, and the first flow channel resumes operation.

[0024] In the above technical scheme, the present invention provides an AO type integrated sewage treatment equipment and treatment method, which has the following beneficial effects: when working, the sewage enters the treatment tank from the liquid inlet and flows along the >-shaped first flow channel composed of the partition, fixed block and mounting block. The sewage contacts the microorganisms attached to the partition, mounting block and fixed block. The microorganisms degrade the organic matter in the sewage, the sewage flow path is lengthened, the area available for microorganism attachment is increased, the number of microorganisms that can participate in the work is increased, and the probability of contact between the organic matter in the sewage and the microorganisms is increased. In the process of sewage flowing, some impurities carried by it will settle under the action of gravity and fall back to the partition and flap along the slope of the fixed block. In order to increase the content of dissolved oxygen in the sewage, the aeration port at the bottom of the treatment tank will intermittently inject air into the treatment tank. The air forms bubbles in the treatment tank. The bubbles move upward and push the flap to flip, so that the substances on both sides of the partition are exchanged (the air moves to the top of the partition, and the impurities accumulated on the partition fall to the bottom of the partition). The bubbles move along the first flow channel, and the oxygen on them gradually dissolves In the sewage, the dissolved oxygen in the sewage is increased. Since the microorganisms are directly attached to the baffle, fixed block and mounting block, the air injected by the aeration port does not disturb the microorganisms, thereby reducing the loss of microorganisms. After a period of operation, a certain amount of sludge and impurities accumulate at the bottom of the sedimentation tank. The movable plate moves downward and pushes the connecting block and baffle to move through the cylindrical rod. The tenon rod on the baffle moves along the slide groove on the inner wall of the sedimentation tank, and the baffle gradually becomes horizontal. During this process, the water below the baffle will move to the top of the baffle through the gap between the baffle and the sedimentation tank or push the flap to rotate and open the gap in the baffle. When the baffle moves to the horizontal position, it fits with the stepped support platform at the bottom of the sedimentation tank. The support platform supports the baffle, and the flap seals the gap in the baffle under the push of the torsion spring. At this time, the baffle divides the treatment tank horizontally, facilitating the extraction of sludge and impurities under the baffle, which can reduce the loss of sewage. Then the movable plate moves up and returns to the initial state. The baffle, fixed block and mounting block cooperate to form the first flow channel in the shape of a >, and the sewage treatment work continues. When maintenance is required inside the treatment pool, the mounting blocks and cylindrical rods can be removed, making it easier for staff to perform maintenance on the treatment pool.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figure 1-11As shown, an AO type integrated sewage treatment equipment includes a treatment tank 1, in which the treatment tank 1 is provided:

[0042] A fixing block 12 having an isosceles triangle cross section;

[0043] A mounting block 13 having a right triangle cross section;

[0044] The partition 11 is movably mounted inside the treatment tank 1 and cooperates with the fixing block 12 and the mounting block 13 to form a >-shaped first flow channel 14. The partition 11 is movably provided with a plurality of flaps 111 facing the aeration ports 133 inside the treatment tank 1, wherein:

[0045] The flap 111 is turned over to allow substances to be exchanged between the two sides of the partition 11 , and the partition 11 moves to a horizontal state to horizontally separate the treatment tank 1 .

[0046] Specifically, the treatment tank 1 is provided with a liquid inlet 15 facing the bottom end of the first flow channel 14, the top surface of the mounting block 13 is flush with the liquid outlet 16 of the treatment tank 1, and the mounting block 13 is provided with a guide block 132 for guiding the sewage to flow to the liquid outlet 16, the mounting block 13 is detachably fixed inside the treatment tank 1 (such as: bolted), the partition 11 is provided with a notch adapted to the flap 111, the partition 11, the mounting block 13 and the fixing block 12 can all be used to attach microorganisms, and cylindrical tenon rods 128 are provided on the side walls on opposite sides of the partition 11, and a slide groove adapted to the tenon rod 128 is provided on the side wall of the treatment tank 1, and a stepped support platform is provided at the bottom of the treatment tank 1. A movable plate 117 is slidingly provided on the wall, a slide groove adapted to the movable plate 117 is provided on the side wall of the treatment tank 1, a connecting block 118 is provided on the partition 11, a cylindrical rod is threadedly connected to the movable plate 117, and a waist-shaped groove 119 adapted to the cylindrical rod is provided on the connecting block 118. A torsion spring is provided between the flap 111 and the partition 11. After the sewage flows out of the first flow channel 14, it will collide with the inner wall of the treatment tank 1 and then move to the mounting block 13, and flow out from the liquid outlet 16 under the guidance of the guide block 132 on the mounting block 13. The guide block 132 can avoid dead angles at the top of the mounting block 13, ensuring that the sewage and impurities carried in the sewage can also flow out smoothly from the liquid outlet 16.

[0047] Furthermore, the movement of the movable plate 117 in the above embodiment can be driven by an electric telescopic rod, or a stepping screw moving module, or other structures that can be obtained by those skilled in the art based on common technical knowledge.

[0048] In the above technical solution, when working, sewage enters the treatment tank 1 from the liquid inlet 15 and flows along the first flow channel 14 of the shape of the > formed by the partition 11, the fixed block 12 and the mounting block 13. The sewage contacts the microorganisms attached to the partition 11, the mounting block 13 and the fixed block 12. The microorganisms degrade the organic matter in the sewage, the sewage flow path is lengthened, the area available for microorganism attachment is increased, the number of microorganisms that can participate in the work is increased, and the probability of contact between the organic matter in the sewage and the microorganisms is increased. In addition, during the flow of sewage, some impurities carried by it will settle under the action of gravity and return along the slope of the fixed block 12. Falling onto the partition 11 and the flap 111, in order to increase the content of dissolved oxygen in the sewage, the aeration port 133 at the bottom of the treatment tank 1 will intermittently inject air into the treatment tank 1, and the air will form bubbles in the treatment tank 1. The bubbles move upward and push the flap 111 to flip, so that the substances on both sides of the partition 11 are exchanged (the air moves to the top of the partition 11, and the impurities accumulated on the partition 11 fall to the bottom of the partition 11). The bubbles move along the first flow channel 14, and the oxygen on them gradually dissolves in the sewage, increasing the dissolved oxygen in the sewage. In addition, since the microorganisms are directly attached to the partition 11, the fixing block 12 and the mounting block 13, the aeration port 133 injects The air introduced does not disturb the microorganisms, thereby reducing the loss of microorganisms; after working for a period of time, a certain amount of sludge and impurities accumulate at the bottom of the sedimentation tank, the movable plate 117 moves downward and pushes the connecting block 118 and the partition 11 to move through the cylindrical rod, and the tenon rod 128 on the partition 11 moves along the slide groove on the inner wall of the sedimentation tank. The partition 11 gradually becomes horizontal, and in this process, the water below the partition 11 will move from the gap between the partition 11 and the sedimentation tank or push the flap 111 to rotate to open the notch on the partition 11 and move to the top of the partition 11. When the partition 11 moves to the horizontal position, it is in contact with the bottom of the sedimentation tank. The stepped support platform at the top is fitted with the support platform, which supports the partition 11, and the flap 111 seals the gap on the partition 11 under the push of the torsion spring. At this time, the partition 11 divides the treatment tank 1 horizontally, which is convenient for pumping out the sludge and impurities under the partition 11, and can reduce the loss of sewage. Then the movable plate 117 moves up and returns to the initial state. The partition 11, the fixed block 12 and the mounting block 13 cooperate to form the >-shaped first flow channel 14 to continue sewage treatment. When maintenance is needed inside the treatment tank 1, the mounting block 13 and the cylindrical rod can be removed, which is convenient for the staff to maintain the treatment tank 1.

[0049] As a further embodiment of the present invention, a receiving groove 112 and a receiving groove 113 are respectively provided at the bottom and the top of the partition 11 . A baffle 114 is provided in the receiving groove 113 and is vertically arranged in the first flow channel 14 .

[0050] Specifically, the plurality of aeration ports 133 are gathered in a region near the bottom end of the first flow channel 14 .

[0051] Furthermore, when the partition 11 cooperates with the fixing block 12 and the mounting block 13 to form the first flow channel 14, the partition 11 is in an inclined state. At this time, the baffle 114 in the receiving groove 113 is in a vertical state. The baffle 114 divides the receiving groove 113 into a plurality of grooves with open tops. Impurities settled in the sewage can more easily enter the receiving groove 113, and the baffle 114 can block the water flow from the rear to prevent the water flow from impacting the impurities in the receiving groove 113. When air is injected into the treatment tank 1 at the aeration port 133, the air is Bubbles are formed in the sewage, move upward and contact the bottom of the flap 111, and then gather in the receiving groove 112 at the bottom of the flap 111 until the bubbles accumulate to a predetermined volume. The flap 111 is pushed by the bubbles to overcome the torsion spring and rotate, that is, the flap 111 flips over. At this time, the receiving groove 112 moves to the top of the partition 11, and the bubbles enter the first flow channel 14 and move along the first flow channel 14. The receiving groove 113 moves to the bottom of the partition 11, and the impurities therein fall to the bottom of the partition 11.

[0052] As another embodiment further provided by the present invention, a rotating shaft for separating the receiving groove 112 and the receiving groove 113 is provided on the partition 11, and the rotating shaft is eccentrically arranged (such as Figure 8 As shown in FIG, the receiving groove 112 is located on the larger side of the partition 11 separated by the rotating shaft and is opposite to the aeration port 133.

[0053] Specifically, a torsion spring is provided between the rotating shaft and the partition 11 .

[0054] Furthermore, the larger the receiving groove 112 is, the more air it can accommodate, which can reduce air escape, and the force applied by the air to the flap 111 is farther from the rotation axis, and the lever arm is larger, so that the air can more easily push the flap 111 to flip.

[0055] Furthermore, in the above embodiment, multiple partitions can be provided in the receiving groove 113 to allow air to converge at the lower end of the flap 111 , so that when the flap 111 releases the air, the air can move a longer distance along the first flow channel 14 .

[0056] As another embodiment further provided by the present invention, a plurality of movable bars 115 are movably provided in the partition 11 , and the partition 11 is moved to a horizontal state so that the movable bars 115 are embedded in the flap 111 .

[0057] Specifically, multiple movable bars 115 are fixedly connected together, and the movable bar 115 located at the edge is provided with a wedge block 116 extending to the outside of the flap 111. A top block 134 for pushing the wedge block 116 is provided in the treatment pool 1. A spring is provided between the movable bar 115 and the partition 11, and a notch adapted to the movable bar 115 is opened on the side wall of the flap 111.

[0058] Furthermore, in the process of the partition 11 moving toward a horizontal state, the water pressure on both sides of the partition 11 is roughly the same, and the flap 111 fits against the partition 11 under the pressure of the sewage above, and at this time, the slope of the wedge block 116 contacts the top block 134, and the top block 134 pushes the wedge block 116 and the movable bar 115 to move, and the movable bar 115 is embedded in the notch on the flap 111. The movable bar 115 spans the partition 11 and the flap 111, fixing the flap 111 on the partition 11, thereby improving the airtightness of the partition 11 and enhancing the ability of the flap 111 to resist the water pressure from above, thereby preventing the flap 111 from being bent by the sewage from above.

[0059] As another embodiment further provided by the present invention, a vertical second flow channel 123 and a first baffle 121 and a second baffle 122 for blocking both ends of the second flow channel 123 are provided on the fixing block 12 .

[0060] Specifically, the first baffle 121 and the second baffle 122 are both hinged to the fixing block 12 .

[0061] Furthermore, when the treatment tank 1 is operating normally, the first baffle 121 and the second baffle 122 seal the second flow channel 123 in the fixed block 12; when a certain amount of sludge and impurities accumulate at the bottom of the treatment tank 1 and need to be cleaned, the partition 11 moves to a horizontal state, the first baffle 121 rotates and fits against the baffle 11, sealing the bottom end of the first flow channel 14, and the sewage flows along the second flow channel 123, and the second baffle 122 seals the top end of the first flow channel 14 to prevent the flowing sewage from continuing to flow into the first flow channel 14 and increase the pressure on the baffle 11 and the flap 111. The sewage flows out of the second flow channel 123 and moves to the top of the mounting block 13 under the guidance of the second baffle 122, and is discharged directly. After cleaning is completed, the baffle 11 returns to its initial position, and the first baffle 121 and the second baffle 122 re-seal the second flow channel 123.

[0062] As another embodiment further provided by the present invention, the partition 11 moves to a horizontal position so that the first baffle 121 and the second baffle 122 respectively block both ends of the first flow channel 14 .

[0063] Specifically, a transmission wheel 126 is provided on the first baffle 121 and the second baffle 122, an ∞-shaped synchronization chain 129 is provided between the two transmission wheels 126, a take-up drum 125 is provided on the first baffle 121, a cable 127 is provided between the take-up drum 125 and the tenon rod 128, and a torsion spring is provided between the first baffle 121 and the fixed block 12, and between the second baffle 122 and the fixed block 12.

[0064] Furthermore, in the process of the partition 11 moving to the horizontal state, the tenon rod 128 pulls the take-up drum 125 to rotate through the cable 127, and the take-up drum 125 drives the first baffle 121 to rotate. The first baffle 121 approaches the partition 11 and gradually seals the bottom end of the first flow channel 14. The torsion spring between the first baffle 121 and the fixed block 12 accumulates elastic potential energy. The first baffle 121 drives the second baffle 122 to rotate through the transmission wheel 126 and the synchronous chain 129. The second baffle 122 seals the top end of the first flow channel 14, and the second flow channel 123 is opened. The sewage can temporarily flow along the second flow channel 123; after the sludge cleaning is completed, the partition 11 moves to an inclined state, the cable 127 is relaxed, and the first baffle 121 is separated from the partition 11, the first flow channel 14 is opened, part of the sewage enters the first flow channel 14, and pushes the second baffle 122 to approach the fixed block 12, so that the second baffle 122 drives the first baffle 121 to rotate, and the water flow impact force on the first baffle 121 is reduced and rotates under the action of the torsion spring, and the greater the rotation angle of the first baffle 121, the smaller the sewage impact force on it, so that it can be re-fitted with the fixed block 12 to seal the bottom end of the second flow channel 123, and the second baffle 122 is fit to the fixed block 12 to seal the top end of the second flow channel 123.

[0065] As another embodiment further provided by the present invention, a first attachment block 124 and a second attachment block 131 for supporting microorganisms are respectively provided on the partition 11 and the mounting block 13, and the inclined ends of the first attachment block 124 and the second attachment block 131 are respectively used to support the first baffle 121 and the second baffle 122.

[0066] Specifically, the first attachment block 124 can improve the pressure resistance of the partition 11. The first attachment block 124 and the second attachment block 131 increase the surface area of the partition 11 and the mounting block 13, allowing more microorganisms to attach. When the first baffle 121 seals the bottom end of the first flow channel 14, the first baffle 121 rests on the inclined surface of the end of the first attachment block 124, making the first baffle 121 more stable. The inclined first baffle 121 also makes it easier to guide sewage into the second flow channel 123. When the second baffle 122 seals the top end of the first flow channel 14, the second baffle 122 rests on the end of the second attachment block 131, making the second baffle 122 more stable and able to guide sewage to the top of the mounting block 13.

[0067] As another embodiment further provided by the present invention, the cross section of the first attachment block 124 is an isosceles triangle, and a flap 111 is movably provided between two adjacent first attachment blocks 124 .

[0068] Specifically, the inclined surface of the first attachment block 124 can guide the impurities falling on the partition 11 to the flap 111, so that the receiving groove 113 can gather more impurities, and in the process of rotation of the flap 111, the receiving groove 112 at the bottom of the flap 111 gradually moves to the top of the partition 11, and the air in the receiving groove 112 will be released more gently, and the release angle is toward the inclined surface of the first attachment block 124, which can allow the sewage near the first attachment block 124 to come into contact with more air, thereby increasing the dissolved oxygen content of this part of the sewage and improving the activity of microorganisms.

[0069] Example 2

[0070] A novel AO-type integrated sewage treatment method, based on the AO-type integrated sewage treatment equipment in Example 1, further comprising the following steps:

[0071] S1. Sewage enters the treatment tank 1 from the liquid inlet 15 and flows along the >-shaped first flow channel 14 formed by the partition 11, the fixing block 12, and the mounting block 13. The sewage comes into contact with microorganisms attached to the partition 11, the mounting block 13, and the fixing block 12, and the microorganisms degrade the organic matter in the sewage.

[0072] S2. As the sewage flows, some of the impurities it carries settle under the action of gravity and fall back onto the partition 11 and the flap 111 along the slope of the fixed block 12. The aeration port 133 at the bottom of the treatment tank 1 intermittently injects air into the treatment tank 1. The air forms bubbles in the treatment tank 1, which move upward and push the flap 111 to flip, causing material exchange on both sides of the partition 11. The bubbles move along the first flow channel 14, and the oxygen in them gradually dissolves in the sewage, increasing the dissolved oxygen in the sewage.

[0073] S3, the movable plate 117 moves downward and pushes the connecting block 118 and the partition 11 to move through the cylindrical rod. The tenon rod 128 on the partition 11 moves along the chute on the inner wall of the sedimentation tank and the partition 11 gradually becomes a horizontal state. In this process, the water below the partition 11 will move from the gap between the partition 11 and the sedimentation tank or push the flap 111 to rotate and open the notch on the partition 11 and move to the top of the partition 11. When the partition 11 moves to the horizontal position, it fits into the stepped support platform at the bottom of the sedimentation tank. The support platform supports the partition 11, and the flap 111 seals the notch on the partition 11 under the push of the torsion spring. At this time, the partition 11 horizontally separates the treatment tank 1;

[0074] S4. The sludge below the partition 11 is pumped away, and the partition 11 is driven to become an inclined state, and the first flow channel 14 resumes operation.

[0075] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
