Description

Technical Field

[0001] The present application relates to the technical field of rural sewage treatment, and specifically to a denitrification device and a deammonification method for AO treatment of rural domestic sewage. Background Art

[0002] Rural sewage refers to sewage discharged from agricultural and animal husbandry production. In rural sewage, the water discharged through irrigation water flowing through farmland or through leakage from farmland contains a large amount of fertilizer residues. The large-scale use of agricultural fertilizers and pesticides causes eutrophication of water bodies caused by a large amount of nitrogen, phosphorus and potassium fertilizers, and water pollution caused by high residues and difficult-to-degrade pesticides. In order to reduce water pollution, sewage is usually treated directly through AO water treatment equipment.

[0003] When using traditional AO water treatment equipment, the reaction raw materials are usually directly put into the anoxic box, and then the sewage in the anoxic box is stirred by a separate stirring device to make the sewage and the reaction raw materials mixed evenly, so that the reaction raw materials can degrade elements such as nitrogen and phosphorus in the sewage. At this time, the separate stirring device usually stirs directly at the center of the anoxic box, resulting in a relatively uniform stirring position, which makes the mixing between the sewage and the reaction raw materials slower. Therefore, in view of the above problems, a denitrification equipment and a deammonification method for AO treatment of rural domestic sewage are proposed. Summary of the invention

[0014] Preferably, the method comprises the following steps:

[0015] Step 1: First, install the anoxic box at a suitable position, then introduce a proper amount of sewage into the anoxic box, then connect the power supply to the anoxic box, start the feeding device through the controller, then the vibration motor starts, the vibration motor drives the top plate to vibrate through the vibration plate, the top plate drives the rubber plate to vibrate, the rubber plate transmits part of the vibration to the reaction raw material in the storage hole opened by the top turntable, at this time, the reaction raw material is more compacted under the action of vibration, then the servo motor drives the turntable to rotate through the main shaft, the turntable drives the reaction raw material in the storage hole to move, until the reaction raw material moves to the top of the discharge hole opened by the mounting seat, at this time, the reaction raw material is dropped into the sewage through the discharge hole, and quantitative automatic feeding of the reaction raw material is realized;

[0016] Step 2: Start the circulation pump through the controller, and the circulation pump drives the sewage in the anoxic box to flow through the guide pipe. At this time, the sewage at the bottom is pumped away through the guide pipe, and the water at the top is filled downward. At the same time, the water pumped away from the bottom is re-injected into the top of the anoxic box. At this time, the water flows obliquely upward through the guide bar, and the water flowing obliquely upward drives the arc plate to rotate. The arc plate drives the shaft to rotate outside the impeller. When the shaft rotates, the baffle can prevent the shaft from falling off. At the same time, the sewage is stirred under the action of the rotation of the arc plate. At the same time, the sewage flows downward through the guide groove and the through groove opened by the diverter plate. At this time, the sewage moves between the two guide plates, and part of the sewage is driven upward by the arc plate to mix and stir with the sewage above. The remaining sewage continues to flow downward under the action of the circulation pump and contacts with another arc plate through the guidance of the guide bar. At this time, the above process is repeated to stir and guide the sewage.

[0017] Step 3: The sewage that has completed the reaction in the anoxic box is pumped into the aerobic box through the bottom outlet valve to continue the reaction. After the reaction is completed, it is sent into the anoxic box through the reflux pipe to mix with new sewage and continue to add an appropriate amount of reaction materials through the feeding device to continue the reaction until the nitrogen content in the sewage reaches the standard.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1. In the present application, by setting up anoxic box, support seat, controller, circulation pump, diversion pipe, diversion device and feeding device, the sewage can be driven to flow through the circulation pump and diversion pipe. At this time, the sewage flows along a specific path in the anoxic box under the action of the diversion device. At this time, the feeding device feeds the reaction raw materials so that the sewage can be mixed with the sewage during the flow process, thereby improving the denitrification efficiency of the sewage;

[0020] 2. In the present application, the diverter plate, limiting shell, guide groove and through groove are arranged, which can cooperate with the anoxic box to form a flow channel, and then the sewage is driven to flow along the flow channel in the anoxic box under the action of the circulating pump and the guide pipe. The rotating shaft, arc plate, baffle, fixed seat, splint, support plate, runner, installation groove, fixed shaft, limiting groove, positioning groove, rubber block and transverse deformation groove are arranged, and the splint can be pushed to rotate outside the fixed shaft under the action of the rubber block and the transverse deformation groove, so as to limit the rotating shaft. When the sewage flows, the arc plate can be driven to rotate, and the arc plate can stir the sewage, so that the mixing of sewage and reaction raw materials is more stable. At the same time, the rotation of the rotating shaft is more stable under the action of the support plate and the runner. Through the two supports The plates fit each other so that a suitable distance can be maintained between the two clamping plates. At the same time, the sewage can be guided by the guide strips so that the sewage moves obliquely upward at the position of the guide groove of the diverter plate. While pushing the arc plate, the sewage moving downward through the through groove opened by the diverter plate can be reduced, so that the sewage flow is more stable. When the shaft is fixed, the baffle can prevent the clamping plate and the shaft from excessively shaking left and right, so that the installation of the diversion device is more stable. Through the positioning plate, the fixing plate and the longitudinal deformation groove, the positioning plate can be installed in the rubber block under the action of the fixing plate, and then the positioning plate is inserted into the positioning groove opened by the fixing seat, so as to limit the rubber block and prevent the rubber block from falling off from the installation groove opened by the fixing seat when it is deformed.

[0021] 3. In the present application, by providing a mounting seat, a feeding body, a feeding pipe, a servo motor, a turntable, a storage hole and a feeding hole, after the reaction raw materials in the feeding body enter the storage hole opened by the turntable, the turntable is driven to rotate by the servo motor, and the turntable drives the reaction raw materials in the storage hole to move to the top of the feeding hole opened by the mounting seat, and then the reaction raw materials are sent into the anoxic box through the feeding hole opened by the mounting seat, so as to realize quantitative feeding, and make the reaction raw materials more evenly distributed in the sewage when the sewage is circulated;

[0022] 4. In the present application, the vibration of the vibration motor can be controlled by a controller through the setting of the mounting shell, rubber plate, bottom plate, plug, bolt, positioning ball, wiring, rubber pad, cross plate, vibration plate, vibration motor and top plate. At this time, the vibration motor transmits the vibration to the top plate through the vibration plate, and the top plate transmits the vibration to the reaction raw materials through the rubber plate, so that the reaction raw materials are more compact in the storage holes opened by the turntable, and the gaps between the reaction raw materials are reduced, so that the reaction raw materials falling into the storage holes opened by the turntable are more uniform, and each feeding is more uniform. At the same time, the rubber pad can reduce the vibration transmitted to the mounting shell, so that the installation of the mounting shell is more stable. At the same time, the bolts can be removed, and the mounting shell can be directly taken out from the mounting seat, and then the rubber plate can be directly removed from the outside of the positioning ball, and then the wiring can be removed from the vibration plate. At this time, the vibration motor can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Working process: firstly, install the anoxic box 1 at a suitable position, then introduce a proper amount of sewage into the anoxic box 1, then connect the power supply to the anoxic box 1, start the feeding device 8 through the controller 3, then the vibration motor 894 starts, the vibration motor 894 drives the top plate 895 to vibrate through the vibration plate 893, the top plate 895 drives the rubber plate 882 to vibrate, the rubber plate 882 transmits part of the vibration to the reaction raw material in the storage hole 86 opened by the top turntable 85, at this time, the reaction raw material is more compacted under the action of vibration, then the servo motor 84 drives the turntable 85 to rotate through the main shaft, the turntable 85 drives the reaction raw material in the storage hole 86 to move, until the reaction raw material moves to above the discharge hole 87 opened by the mounting seat 81, at this time, the reaction raw material passes through the discharge Hole 87 is poured downward into the sewage to realize quantitative automatic feeding of reaction raw materials. The circulation pump 4 is started by the controller 3. The circulation pump 4 drives the sewage in the anoxic box 1 to flow through the guide pipe 5. At this time, the sewage at the bottom is pumped away through the guide pipe 5, and the water at the top is filled downward. At the same time, the water pumped away from the bottom is re-injected into the top of the anoxic box 1. At this time, the water flows obliquely upward through the guide strip 7. The water flowing obliquely upward pushes the arc plate 652 to rotate. The arc plate 652 drives the rotating shaft 651 to rotate outside the impeller 664. When the rotating shaft 651 rotates, the baffle 653 can prevent the rotating shaft 651 from falling off. At the same time, the sewage is stirred under the action of the rotation of the arc plate 652. At the same time, the sewage flows downward through the guide groove 63 and the through groove 64 opened by the diverter plate 61. Flow, at this time the sewage moves to between the two guide plates 61, part of the sewage is driven upward by the arc plate 652 to mix and stir with the sewage above, and the remaining sewage continues to flow downward under the action of the circulation pump 4, and contacts with another arc plate 652 through the guidance of the guide bar 7. At this time, the above process is repeated to stir and guide the sewage. At the same time, the feeding device 8 can feed, so that the reaction raw materials can be put into other sewage without reaction raw materials, thereby improving the reaction efficiency of the sewage and realizing the denitrification and phosphorus removal of the sewage. The sewage that has completed the reaction in the anoxic box 1 is pumped into the aerobic box through the bottom outlet valve to continue the reaction. After the reaction is completed, it is sent into the anoxic box 1 through the reflux pipe to mix with the new sewage and continue to be fed with an appropriate amount of reaction materials through the feeding device 8 to continue the reaction. The nitrogen content in the sewage reaches the standard. When the impeller 664 and the rubber block 681 need maintenance, the diverter plate 61 is removed from the anoxic box 1, and then the rotating shaft 651 is moved upward. The rotating shaft 651 drives the upper push clamping plate 662 to rotate on the outside of the fixed shaft 666. At the same time, the bottom of the clamping plate 662 pushes the rubber block 681 to deform through the limit groove 667. At this time, the rubber block 681 is deformed through the lateral deformation groove 684 opened by itself. After the rotating shaft 651 is taken out, it is reset by the rubber block 681 under the action of its own elastic force, and the clamping plate 662 is reset at the same time. At this time, the bottoms of the supporting plates 663 set by the two clamping plates 662 fit each other, and then the clamping plate 662 is pushed. The clamping plate 662 drives the fixed seat 661 to gradually leave the limit shell 62.Until the clamping plate 662 moves from the slot 67 of the diverter plate 61 to the through slot 64 of the diverter plate 61, the clamping plate 662 and the fixing seat 661 can be removed from the diverter plate 61 for maintenance, and then the rubber block 681 can be pushed to drive the positioning plate 682 to move through the fixing plate 683. At this time, the rubber block 681 is deformed through the longitudinal deformation groove 685 until the rubber block 681 drives the positioning plate 682 to leave the positioning groove 668 of the fixing seat 661. At this time, the rubber block 681 can be taken out from the installation groove 665 of the fixing seat 661, and then the aged rubber block 681 can be replaced, and then the rubber block 681 can be installed back to the installation groove 665 of the fixing seat 661 according to the reverse steps above. 5, at this time, the positioning plate 682 is inserted into the positioning groove 668 provided in the fixing seat 661 to prevent it from falling off. At this time, the rubber block 681 pushes the clamping plate 662 to move under the action of its own elastic force, and the clamping plate 662 drives the supporting plate 663 to fit each other. Then, the fixing seat 661 is installed back into the limiting shell 62, and at the same time, the clamping plate 662 passes through the slot 67 provided in the diverter plate 61. Then, the rotating shaft 651 is placed above the clamping plate 662, and the rotating shaft 651 is moved downward. The rotating shaft 651 pushes the clamping plate 662 to rotate outside the fixed shaft 666, and at the same time, the clamping plate 662 pushes the rubber block 681 to deform. After the rotating shaft 651 moves between the two clamping plates 662, the two ends of the bottom of the rotating shaft 651 fit each other with the rotating wheel 664, and finally, the diverter plate 61 is installed back into the anoxic box 1. ,
