Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment technology, and in particular relates to a hydrolysis acidification coupled anaerobic ammonia oxidation process device. Background Technology

[0002] The hydrolysis-acidification coupled anaerobic ammonium oxidation (AMA) process is an innovative technology proposed to address the treatment challenges of industrial wastewater with high ammonia nitrogen and low carbon-to-nitrogen ratio (C / N<3) (such as pharmaceutical, landfill leachate, and food processing wastewater). Traditional processes face problems such as high carbon source addition costs, large sludge production, and low nitrogen removal efficiency. Meanwhile, the single anaerobic ammonium oxidation (Anammox) process is sensitive to organic matter (inhibiting Anammox bacteria activity when COD>200mg / L). This technology decomposes complex organic matter into small-molecule volatile fatty acids (VFAs) through a hydrolysis-acidification unit, thereby improving the biodegradability of the wastewater. Furthermore, the COD concentration entering the Anammox unit is controlled. Simultaneously, the Anammox unit utilizes some of the nitrite produced by hydrolysis and acidification to directly react with the remaining ammonia nitrogen to generate nitrogen gas, achieving efficient nitrogen removal. Through the zonal regulation of the microbial community (synergistic action of hydrolysis and acidification bacteria and Anammox bacteria) and process optimization (such as micro-oxygen control), the total nitrogen removal rate can reach over 90% without the need for an external carbon source, and sludge production is reduced by 40% to 60%, significantly reducing operating energy consumption and treatment costs. It is especially suitable for the low-carbon treatment of highly challenging wastewaters such as traditional Chinese medicine wastewater and landfill leachate.

[0003] In existing technologies, anaerobic reactors are usually installed inside the tank by hoisting. However, the stirring device often needs to be hoisted separately after the anaerobic reactor is installed. The construction process is cumbersome, and the equipment positioning needs to be repeatedly adjusted, making it difficult to guarantee installation accuracy. At the same time, this arrangement is not conducive to later maintenance and repair. On the other hand, when the sewage flows along the outer wall of the biological packing pipe, the flow velocity is high and the residence time is short, making it difficult to fully contact and react with microorganisms, thus affecting the treatment effect. Utility Model Content

[0004] This invention provides a hydrolysis-acidification coupled anaerobic ammonia oxidation process apparatus, which aims to solve the following problems.

[0005] This utility model is implemented as follows: a hydrolysis acidification coupled anaerobic ammonia oxidation process device includes: a tank body, a support installed in the tank body, a three-phase separator installed in the support, a biological packing tube installed in the support, the three-phase separator being fixedly connected above the biological packing tube, an outlet pipe installed on one side of the three-phase separator, an outlet weir fixedly connected to the upper surface of the three-phase separator, an inlet water supply pipe fixedly connected to the outside of the support, two stirring devices assembled outside the support, and a water-blocking device assembled outside the support;

[0006] The stirring device includes a connecting shell, which is fixedly connected to the outside of the support. An installation plate is installed inside the connecting shell. A horizontal plate is fixedly connected to the upper surface of the installation plate. A waterproof motor is installed inside the horizontal plate. A rotating shaft is fixedly connected to the output end of the waterproof motor. A stirring blade is installed at one end of the rotating shaft.

[0007] Preferably, the connecting shell and the mounting plate form a sliding connection, and the mounting plate has a rectangular groove inside.

[0008] Preferably, a compression block is installed inside the rectangular groove, a telescopic rod is installed inside the compression block, the telescopic rod is fixedly connected inside the rectangular groove, and a return spring is provided on the outer sleeve of the telescopic rod.

[0009] Preferably, one end of the pull-back spring is fixedly connected to the extrusion block, and the other end of the pull-back spring is fixedly connected to the rectangular groove.

[0010] Preferably, the size of the rectangular groove is larger than the size of the extrusion block, and the extrusion block and the rectangular groove form a sliding connection.

[0011] Preferably, the water-blocking device includes a baffle, two long plates are fixedly connected to the outside of the baffle, and fastening bolts are installed inside the long plates and fixedly connected to the outside of the biological packing tube.

[0012] Preferably, the baffle is configured in a spiral shape to control the direction of water flow.

[0013] Compared with related technologies, the hydrolysis-acidification coupled anaerobic ammonia oxidation process device provided by this utility model has the following beneficial effects:

[0014] 1. In this utility model, the mounting plate below the horizontal plate is inserted into the corresponding connecting shell. The pressing block slides in the rectangular groove by external pressure. When the pressing block moves to the bottom of the connecting shell and is freed from the external pressure, the return spring applies a reset force to the pressing block, causing it to spring back and automatically lock into the bottom of the connecting shell, thus locking the mounting plate. This structure allows for the integrated installation of the anaerobic reactor, waterproof motor, and stirring blades during hoisting. When it is necessary to repair the motor or stirring components, simply press the pressing block to release the mounting plate. The operation is simple and the maintenance is convenient, effectively improving the assembly efficiency and maintenance convenience of the equipment.

[0015] 2. In this utility model, the baffle structure is installed on the outside of the support by means of a sleeve, and after being moved to the target position, the long plate is fixedly connected to the bracket by fastening bolts. The baffle is spirally arranged on the outer wall of the biological packing tube. When the sewage gradually rises in the tank, it needs to flow slowly around the spiral channel, thereby prolonging its residence path and time on the outer wall of the packing tube. This structure helps to improve the contact efficiency between sewage and biological packing, and enhance the sufficiency and stability of microbial treatment in the reactor.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model provides a hydrolysis-acidification coupled anaerobic ammonia oxidation process apparatus, such as... Figure 1-5 As shown, it includes: a pool body 1, a support 2 installed inside the pool body 1, a three-phase separator 3 installed inside the support 2, a biological packing tube 4 installed inside the support 2, the three-phase separator 3 fixedly connected above the biological packing tube 4, an outlet pipe 5 installed on one side of the three-phase separator 3, an outlet weir 6 fixedly connected to the upper surface of the three-phase separator 3, an inlet water supply pipe 7 fixedly connected to the outside of the support 2, two stirring devices 8 assembled outside the support 2, and a water-blocking device 9 assembled outside the support 2.

[0025] The stirring device 8 includes a connecting shell 801, which is fixedly connected to the outside of the support. An installation plate 802 is installed inside the connecting shell 801. A horizontal plate 803 is fixedly connected to the upper surface of the installation plate 802. A waterproof motor 804 is installed inside the horizontal plate 803. A rotating shaft 805 is fixedly connected to the output end of the waterproof motor 804. A stirring blade 806 is installed at one end of the rotating shaft 805.

[0026] In a further preferred embodiment of this utility model, the connecting shell 801 and the mounting plate 802 are slidably connected. A rectangular groove 807 is provided in the mounting plate 802. An extrusion block 808 is installed in the rectangular groove 807. A telescopic rod 809 is installed in the extrusion block 808. The telescopic rod 809 is fixedly connected in the rectangular groove 807. A return spring 810 is provided on the outer sleeve of the telescopic rod 809. One end of the return spring 810 is fixedly connected in the extrusion block 808, and the other end of the return spring 810 is fixedly connected in the rectangular groove 807. The size of the rectangular groove 807 is larger than the size of the extrusion block 808, and the extrusion block 808 and the rectangular groove 807 are slidably connected.

[0027] In this embodiment, the extrusion block 808 is installed in the rectangular groove 807, forming a sliding fit. The size of the rectangular groove 807 is slightly larger than the body of the extrusion block 808, allowing it to slide smoothly in a preset direction under pressure, while restricting its excessive degrees of freedom. This fit structure ensures smooth extrusion while achieving stable limit control, providing a reliable guiding foundation for the rapid locking and releasing of the mounting plate 802. The telescopic rod 809 is set inside the extrusion block 808, and one end of the pull spring 810 fitted on it is connected to the extrusion block 808, while the other end is fixedly connected to the rectangular groove 807. This combined structure allows the extrusion block 808 to automatically reset after the external force is removed, without additional manual intervention, thereby improving the mechanical response efficiency and ease of operation of the structure, and is particularly suitable for occasions that require frequent disassembly and assembly.

[0028] In a further preferred embodiment of the present invention, the water-blocking device 9 includes a baffle 901, two long plates 902 are fixedly connected to the outside of the baffle 901, and fastening bolts 903 are installed inside the long plates 902. The fastening bolts 903 are fixedly connected to the outside of the biological packing tube 4. The baffle 901 is configured as a spiral shape to control the direction of water flow.

[0029] In this embodiment, the spiral baffle 901 is fixed to the outer wall of the target structure by two long plates 902. The long plates 902 provide rigid support, while the baffle 901 adjusts its angle to fit the outer surface of the biological packing tube 4 as needed. This mating structure takes into account both flexible flow guidance and rigid installation, which helps to guide the water flow to rise slowly along the set path, thereby extending the flow path and residence time.

[0030] In summary, by inserting the mounting plate 802 below the horizontal plate 803 into the corresponding connecting shell 801, and by applying external pressure to make the pressing block 808 slide within its rectangular groove 807, once the pressing block 808 moves below the connecting shell 801 and is freed from external pressure, the return spring 810 applies a restoring force to the pressing block 808, causing it to spring back and automatically lock into place below the connecting shell 801, thus locking the mounting plate 802. This structure allows for the installation of an anaerobic reactor and waterproofing during hoisting. The motor 804 and the stirring blade 806 are installed as a whole; when it is necessary to repair the motor or stirring parts, it is only necessary to press the squeezing block 808 to release the mounting plate 802, which is simple to operate and easy to maintain. The baffle 901 structure is installed on the outside of the support by means of a sleeve, and after being moved to the target position, the long plate 902 is fixedly connected to the bracket 2 by fastening bolts 903. The baffle 901 is spirally arranged on the outer wall of the biological filler pipe 4. When the sewage gradually rises in the tank 1, it needs to flow slowly around the spiral channel.
