[0040] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0044] Example 1:

[0045] As Figure 1 — Figure 15 shown, a spallation distributed aerobic reaction device and process include an aerobic tank 1. A plurality of internal wastewater device partition walls 3 are uniformly arranged in the aerobic tank 1. The plurality of internal wastewater device partition walls 3 divide the space inside the aerobic tank 1 into a plurality of aerobic intervals. A distributed aeration system 4 and a DO meter 5 are arranged in the aerobic intervals on the aerobic tank 1. The wastewater in the aerobic tank 1 is diverted through the diversion grooves arranged on the plurality of internal wastewater device partition walls 3.

[0046] The working principle and beneficial effects of this embodiment are as follows: Domestic sewage, printing and dyeing wastewater, papermaking wastewater, medical wastewater, food wastewater and other wastewater are treated. The wastewater treated by the anaerobic device is added into the aerobic tank 1. During the flowing addition process in the aerobic tank 1, it successively passes through the diversion grooves arranged on the partition walls 3 of multiple internal wastewater devices for diversion, and then is added into different multiple aerobic zones during the flowing process, effectively making the hydraulic retention time relatively longer. In different aerobic zones, the oxygen added from the bottom by the distributed aeration system 4 prolongs the aerobic degradation time. In the aerobic tank 1, the organic substances in the sewage are decomposed into harmless substances through the metabolic activities of microorganisms. The oxygen content in the aerobic tank 1 is monitored in real time by the DO meter 5, and then the nitrogen in the wastewater is effectively removed through nitrification and denitrification. Through the reaction and accumulated sediment of sludge, using the metabolic activities of polyphosphate-accumulating bacteria under anaerobic and aerobic conditions, the polyphosphate-accumulating bacteria excessively absorb phosphates, synthesize polyphosphates and store them in the cells, and are discharged and removed through the sludge.

[0047] Furthermore, by dividing the aerobic tank into multiple compartments, and each compartment adopts a spallation distributed water flow, the water body is effectively mixed, and the mixing efficiency is improved; the spallation distribution also effectively makes the hydraulic retention time relatively longer; the spallation distribution also effectively makes the water flow pattern more complex and the hydraulic distribution system more complex. Further prolongs the aerobic degradation time, increases the contact time of the bacteria species, and has more contact surfaces, etc.; effectively improves the efficiency of the metabolic activities of microorganisms.

[0048] Embodiment 2:

[0049] As Figure 1 — Figure 15 shown, a spallation distributed aerobic reaction device and process, a wastewater inlet 2 for adding wastewater and an aerobic outlet 6 for discharging wastewater are respectively fixed at both ends of the aerobic tank 1.

[0050] The working principle and beneficial effects of this embodiment are as follows: The wastewater treated by the anaerobic equipment is added into the aerobic tank 1 through the wastewater inlet 2. The wastewater flowing and being treated in the aerobic tank 1 overflows to the aerobic outlet 6 as it is continuously added. The clean upper end of the treated wastewater floats to the aerobic outlet 6 and is discharged to the next wastewater purification device.

[0051] Embodiment 3:

[0052] As Figure 1 — Figure 15 shown, a spallation distributed aerobic reaction device and process, a recovery bin 8 for collecting impurities is fixed at the wastewater adding end of the aerobic tank 1, and an operation platform 9 is arranged at the side end of the aerobic tank 1.

[0053] The working principle and beneficial effects of this embodiment are as follows: The recycling bin 8 is arranged at the wastewater adding end of the aerobic tank 1, facilitating the discharged floating solid impurities to be poured into it by the oxygen-dispersing impurity carrier 7 for collection and recycling; an operating platform 9 is arranged at the side end of the aerobic tank 1, facilitating the on-site staff to perform real-time control through the display and frequency conversion control device on the operating platform 9, which is convenient for automated control processing.

[0054] Embodiment 4:

[0055] As Figure 1 — Figure 15 As shown in the figure, for a spallation distributed aerobic reaction device and process, the internal wastewater device partition wall 3 includes a side-by-side diversion trough partition wall, a bottom diversion trough partition wall, and an upper diversion trough partition wall. The upper diversion trough partition wall is fixed in the middle of the aerobic tank 1. Two side-by-side diversion trough partition walls are respectively arranged on both sides of the upper diversion trough partition wall. The side-by-side diversion trough partition wall and the bottom diversion trough partition wall are arranged at intervals in the aerobic tank 1; an oxygen-dispersing impurity carrier 7 is arranged on the wastewater adding side of the upper diversion trough partition wall.

[0056] The working principle and beneficial effects of this embodiment are as follows: By uniformly arranging and fixing multiple internal wastewater device partition walls 3 in the aerobic tank 1, the internal space of the aerobic tank 1 is divided into multiple aerobic zones, enabling separate aeration treatment for independent aerobic zones, thereby improving the efficiency of wastewater aeration reaction; the upper diversion trough partition wall is fixed in the middle of the aerobic tank 1, facilitating separation on both sides. Since there is only one diversion trough at the upper part of the upper diversion trough partition wall, after the wastewater adding side is full, it flows into the next aerobic zone through the upper diversion trough, playing a role of central separation;

[0057] Two side-by-side diversion trough partition walls are respectively arranged on both sides of the upper diversion trough partition wall, facilitating the inflow and outflow of wastewater. The side-by-side diversion trough partition wall and the bottom diversion trough partition wall are arranged at intervals in the aerobic tank 1, effectively reducing the flow efficiency of wastewater, enabling the hydraulic retention time to be relatively longer during the wastewater flow process; further lengthening the aerobic degradation time, increasing the contact time of bacteria, and having more contact surfaces, etc.; effectively improving the efficiency of microbial metabolic activities;

[0058] An oxygen-dispersing impurity carrier 7 is arranged on the wastewater adding side of the upper diversion trough partition wall. By arranging the oxygen-dispersing impurity carrier 7 at the end with a larger impurity content at the wastewater adding end, while effectively dispersing oxygen, the aerobic degradation time is lengthened, and at the same time, the floating solid impurities in the wastewater are discharged; if the effect is limited, an oxygen-dispersing impurity carrier 7 can be synchronously arranged on the wastewater outflow side of the aerobic tank 1 to further improve the treatment efficiency.

[0059] Embodiment 5:

[0060] As Figure 1 — Figure 15As shown in the figure, a spallation distributed aerobic reaction device and process, on the side of the upper diversion trough partition wall where wastewater is added, a DO meter 5 is inserted and fixed on the aerobic tank 1.

[0061] The working principle and beneficial effects of this embodiment are as follows: Adding a DO meter 5 on the side of the upper diversion trough partition wall where wastewater is added facilitates detecting the dissolved oxygen content inside the side of the upper diversion trough partition wall where wastewater is added in a timely manner, and then controlling the added oxygen, so that the dissolved oxygen content is within a certain range, and then effectively removing nitrogen in the wastewater through nitrification and denitrification in the wastewater. The amount of oxygen can be effectively controlled by the DO. The DO in the anoxic zone is controlled between 2.0 and 3.0. When it is higher or lower than this range, the automatic control system starts to automatically adjust the aeration system 4, correspondingly closing or opening it larger; it can also be flexibly separated by the inner wastewater device partition wall 3 and the distributed aeration system 4 according to different wastewater treatments.

[0062] Example 6:

[0063] As Figure 1 — Figure 15 As shown in the figure, a spallation distributed aerobic reaction device and process, the distributed aeration system 4 includes an aeration addition main pipe 10, a plurality of aeration addition dispersion pipes 11 and a plurality of aeration holes 12. The aeration addition main pipe 10 is fixed on the aerobic tank 1. The aeration addition main pipe 10 is fixed and connected to a plurality of aeration addition dispersion pipes 11. A plurality of aeration addition dispersion pipes 11 are respectively fixed at the bottom ends of a plurality of aerobic intervals. A plurality of aeration holes 12 are provided on each of the plurality of aeration addition dispersion pipes 11.

[0064] The working principle and beneficial effects of this embodiment are as follows: The aeration addition main pipe 10 is fixedly and sealedly connected to a blower. Air oxygen is added into the aeration addition main pipe 10 through the blower, and it is dispersed to a plurality of aeration addition dispersion pipes 11 through the aeration addition main pipe 10. Since a plurality of aeration addition dispersion pipes 11 are respectively fixed at the bottom ends of a plurality of aerobic intervals, and a plurality of aeration holes 12 are provided on each of the plurality of aeration addition dispersion pipes 11, synchronous oxygen addition to a plurality of aerobic intervals is realized. It is discharged from the bottom end of the aerobic tank 1 through the plurality of aeration holes 12, flows into the wastewater and gradually floats upward. During the floating process, it continuously dissolves in the wastewater, promoting the metabolic activities of microorganisms. Based on processes such as biological nitrogen removal, biodegradation and physical precipitation, a large amount of oxygen exists in the aerobic tank, which breeds aerobic bacteria. The biodegradation in the aerobic tank uses oxygen to metabolize organic matter and decomposes it into carbon dioxide and water to complete wastewater purification.

[0065] Example 7:

[0066] As Figure 1 — Figure 15As shown in the figure, a spallation distributed aerobic reaction device and process, the oxygen-dispersing impurity carrier 7 includes a servo driver 13, a transmission sprocket shaft 14, a transport and dispersion fixing frame 15, a transport and dispersion seat 16, two acrylic chains 17, a driven tail-end sprocket shaft 18 and a pressing sprocket 19. The transport and dispersion fixing frame 15 is fixedly arranged in an inclined shape in the aerobic tank 1 and multiple aerobic zones. On one side of the upper end of the transport and dispersion fixing frame 15, a servo driver 13 is fixed. The servo driver 13 drives the transmission sprocket shaft 14 to rotate at the upper end of the transport and dispersion fixing frame 15 through a gear belt drive. The transmission sprocket shaft 14 is connected to the driven tail-end sprocket shaft 18 through two acrylic chains 17. The driven tail-end sprocket shaft 18 rotates on the tail side of the lower end of the transport and dispersion fixing frame 15. A plurality of transmission and dispersion seats 16 are evenly fixed on the acrylic chains 17. At the turning corners of the acrylic chains 17, a plurality of pressing sprockets 19 are engaged. A plurality of pressing sprockets 19 are all rotatably connected to the transport and dispersion fixing frame 15.

[0067] The working principle and beneficial effects of this embodiment are as follows: The transport and dispersion fixing frame 15 is fixedly arranged in an inclined shape in the aerobic tank 1 and multiple aerobic zones for fixed support. The servo driver 13 is controlled to rotate. The transmission sprocket shaft 14 is driven to rotate at the upper end of the transport and dispersion fixing frame 15 through a gear belt drive. The rotating transmission sprocket shaft 14 makes the driven tail-end sprocket shaft 18 rotate synchronously through two acrylic chains 17, completing the setting of cyclic addition and export.

[0068] The driven tail-end sprocket shaft 18 rotates on the tail side of the lower end of the transport and dispersion fixing frame 15, which is convenient for directly adding horizontally into the aerobic tank 1. A plurality of transmission and dispersion seats 16 are evenly fixed on the acrylic chains 17, driving the plurality of transmission and dispersion seats 16 to be directly added horizontally into the aerobic tank 1. At the turning corners of the acrylic chains 17, a plurality of pressing sprockets 19 are engaged. A plurality of pressing sprockets 19 are all rotatably connected to the transport and dispersion fixing frame 15. Thus, the acrylic chains 17 can be offset in the displacement direction for transmission meshing support, and at the same time, the horizontal addition can be made more stable. The continuously added plurality of transmission and dispersion seats 16 can break up the floating oxygen bubbles and promote their full absorption into the wastewater for reaction.

[0069] Embodiment 8:

[0070] As Figure 1 — Figure 15 shown in the figure, a spallation distributed aerobic reaction device and process, the transport and dispersion seat 16 includes an impurity transport and dispersion frame 20, a water filtration hole 21 and an oxygen-dispersing wheel 22. The impurity transport and dispersion frame 20 is fixed between two acrylic chains 17. A plurality of water filtration holes 21 are evenly arranged on the impurity transport and dispersion frame 20. An oxygen-dispersing wheel 22 is rotatably arranged on the impurity transport and dispersion frame 20;

[0071] The impurity transport and dispersion frame 20 and the two acrylic chains 17 are both inserted through a plurality of side-by-side diversion groove partitions and a plurality of bottom diversion groove partitions.

[0072] The working principle and beneficial effects of this embodiment are as follows: The impurity dispersion rack 20 is fixed between two acrylic chains 17, enabling synchronous addition when the two acrylic chains 17 are driven for addition. A plurality of water filtering holes 21 are evenly arranged on the impurity dispersion rack 20, facilitating the filtering out of the wastewater remaining inside after leaving the wastewater, preventing accumulation. A diffused oxygen wheel 22 is rotatably arranged on the impurity dispersion rack 20. When the impurity dispersion rack 20 is synchronously added, the diffused oxygen wheel 22 faces downward. During the horizontal addition process, the floating bubbles in different aerobic regions can be automatically rotated and dispersed, enabling them to be dispersed into multiple fine bubbles and fully integrated into the wastewater for sufficient reaction. At the same time, the dispersion fixing rack 15 is fixed in an inclined shape in the aerobic tank 1 and multiple aerobic intervals, and its inclined effect enables the collected impurities to fall onto the recovery bin 8 at the downward turning point of the impurity dispersion rack 20 for effective impurity removal and recovery.

[0073] Both the impurity dispersion rack 20 and the two acrylic chains 17 are inserted through a plurality of side-by-side diversion trough partition walls and a plurality of bottom diversion trough partition walls, and are fixed to the middle of the aerobic tank 1 in combination with the upper diversion trough partition wall. When used within the upper diversion trough partition wall, inserting through a plurality of side-by-side diversion trough partition walls and a plurality of bottom diversion trough partition walls does not affect the flow direction of the water flow.

[0074] Example 9:

[0075] As Figure 1 — Figure 15 shown, a spallation distributed aerobic reaction process, applicable to a spallation distributed aerobic reaction device, includes the following steps:
