[0017] This invention provides a high-efficiency biological treatment device for landfill leachate utilizing aerobic biological treatment. It has the following beneficial effects:

[0018] 1. This high-efficiency biological treatment device for landfill leachate utilizes aerobic biological treatment. By setting up filter plates, large particles of impurities are intercepted, preventing subsequent aerobic microorganisms from agglomerating around these large particles to form large microbial flocs. This reduces the inducing factors for microbial aggregation, allowing aerobic microorganisms to exist in a relatively dispersed state in the water body. This increases the contact area between aerobic microorganisms and oxygen, thereby improving the treatment efficiency of landfill leachate. Furthermore, a backwash nozzle is installed, driven by a third motor to rotate, facilitating the washing away of impurities accumulated on the filter plate surface. This effectively removes impurities accumulated within and on the surface of the filter screen, reopening the pores and restoring the filter's filtration throughput, ensuring the device's treatment capacity. Impurities fall to the lowest part of the filter plate under gravity, and the first motor then causes a comb-shaped arc scraper to promptly scrape the accumulated impurities into the impurity collection tank for collection, preventing impurity accumulation from affecting the filter's treatment capacity and further improving the treatment efficiency of landfill leachate.

[0019] 2. This efficient biological treatment device for landfill leachate utilizing aerobic biological treatment, by setting multiple sets of second baffles and first baffles on the surface of the first fixed block, and by starting a dual-head motor to drive the second and third rotating shafts to rotate, allows oxygen to be better diffused to all corners of the leachate, avoiding local hypoxia or hyperxia, ensuring that aerobic microorganisms can obtain sufficient oxygen for metabolic activities throughout the entire treatment area, thereby improving the treatment efficiency of landfill leachate.

[0020] 3. This high-efficiency biological treatment device for landfill leachate utilizing aerobic biological treatment utilizes an arc-shaped baffle plate mounted on the surface of a second rotating block via a fixed rod. After aeration through the air outlet pipe, the rotation of the second rotating block drives the arc-shaped baffle plate to rotate. Initially, when the oxygen content is low, the oxygen rises directly through the gap between the arc-shaped baffle plate and the second rotating block. As the oxygen content gradually increases, some of the oxygen is broken and separated by the through-holes on the surface of the arc-shaped baffle plate, further generating a large number of oxygen bubbles, making the oxygen bubbles more dispersed and avoiding local hypoxia or hyperxia. As the oxygen content increases again, some of the oxygen is guided along the surface of the arc-shaped baffle plate to the inner surface of the reaction tank, avoiding the problem of uneven oxygen distribution caused by oxygen supply through the air outlet pipe alone. This provides sufficient oxygen for aerobic microorganisms, thereby improving the treatment efficiency of landfill leachate.

[0021] 4. This efficient biological treatment device for landfill leachate utilizing aerobic biological treatment, by setting up a collection tank and using the stirring of the second rotating block and the first rotating block, facilitates the collection of impurities produced by aerobic microorganisms through the microfiltration membrane into the interior of the collection tank, preventing them from accumulating in the reaction tank, thereby avoiding the inhibition of the growth and metabolism of aerobic microorganisms, ensuring the efficient operation of the biological treatment process, and thus improving the treatment efficiency of landfill leachate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0033] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a high-efficiency biological treatment device for landfill leachate using aerobic biological treatment, comprising a reaction tank 1, an impurity collection tank 3 fixedly connected to the top of the reaction tank 1, a filter separation box 2 fixedly connected to the surface of the impurity collection tank 3, a level gauge 4 and a dissolved oxygen meter 5 fixedly connected inside the reaction tank 1, a leachate filtration mechanism 6 fixedly connected to the top of the reaction tank 1, a uniform stirring mechanism 7 rotatably connected inside the reaction tank 1, a biological sludge collection mechanism 8 fixedly connected inside the reaction tank 1, and an intelligent air outlet pipe 9 fixedly connected to the top of the reaction tank 1;

[0034] Leachate filtration mechanism 6 includes:

[0035] The first rotating shaft 68 is rotatably connected inside the filter separation box 2, and a rotating drum 67 is fixedly connected to the surface of the first rotating shaft 68.

[0036] A comb-tooth arc-shaped scraper 612 is fixedly connected to the surface of the rotating drum 67, a second motor 66 is fixedly connected to the shaft of the rotating drum 67, and a water inlet pipe 69 is fixedly connected to the top of the filter separation box 2.

[0037] A third motor 611 is fixedly connected to the surface of the filter separation box 2. The third motor 611 is fixedly connected to the first pipe 64 through the output shaft. A backwash nozzle 62 is fixedly connected to the surface of the first pipe 64. A flushing water inlet pipe 63 is also fixedly connected to the surface of the first pipe 64. The flushing water inlet pipe 63 is fixedly connected to the surface of the filter separation box 2.

[0038] A filter plate 65 is fixedly connected inside the filter separation box 2, and a connecting pipe 610 is fixedly connected to the bottom of the filter separation box 2. A first motor 61 is fixedly connected to the surface of the filter separation box 2. A first rotating shaft 68 is fixedly connected inside the first motor 61 through an output shaft. A groove is opened on the surface of the filter separation box 2, and an impurity collection groove 3 is located below the groove opened in the filter separation box 2.

[0039] In use, the landfill leachate is first introduced through the inlet pipe 69. After a brief stay inside the filtration and separation chamber 2, the landfill leachate flows through the filter plate 65 into the reaction tank 1. The amount of landfill leachate entering is limited by the real-time measurement of the level gauge 4. At the same time as filtration, the first motor 61 is started. The start of the first motor 61 drives the first rotating shaft 68 to rotate through the output shaft. The rotation of the first rotating shaft 68 drives the rotating drum 67 to rotate around the axis of the first rotating shaft 68. At the same time, the second motor 66 is started. The start of the second motor 66 drives the rotating drum 67 to rotate around the output shaft of the second motor 66 through the output shaft. The rotation of the rotating drum 67 drives the comb-tooth arc scraper 612 to rotate, thereby sweeping the impurities accumulated at the bottom of the filter plate 65 into the impurity collection tank 3 for collection.

[0040] After the filter plate 65 has been used for a period of time, the third motor 611 can be started. The start of the third motor 611 drives the first pipe 64 to rotate through the output shaft, thereby spraying the water in the flushing water inlet pipe 63 at different angles through the first pipe 64 and the backwash nozzle 62 onto the surface of the filter plate 65, washing off the impurities on the surface of the filter plate 65, so that the comb-tooth arc scraper 612 can sweep them into the impurity collection tank 3.

[0041] By setting up filter plates 65, large particles of impurities are intercepted, preventing subsequent aerobic microorganisms from agglomerating around these large particles to form large microbial flocs. This reduces the inducing factors for microbial aggregation, allowing aerobic microorganisms to exist in a relatively dispersed state in the water, increasing the contact area between aerobic microorganisms and oxygen, thereby improving the treatment efficiency of landfill leachate. Furthermore, a backwash nozzle 62 is installed, which rotates when the third motor 611 is activated, facilitating the washing away of impurities accumulated on the surface of the filter plates 65. This effectively removes impurities accumulated within and on the surface of the filter screen, reopening the pores and restoring the filter's filtration throughput, ensuring the device's processing capacity. Impurities fall to the lowest part of the filter plates 65 under gravity, and the first motor 61 activates the comb-shaped arc scraper 612 to promptly scrape the accumulated impurities into the impurity collection tank 3 for collection, preventing impurity accumulation from affecting the filter's processing capacity, thus further improving the treatment efficiency of landfill leachate.

[0042] Example 2: Please refer to Figures 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0043] The uniform stirring mechanism 7 includes a fourth motor 71, which is fixedly connected to the top of the reaction vessel 1.

A connecting shaft 718 is fixedly connected to the bottom of the first rotating block 72. A second rotating block 73 is fixedly connected to the bottom of the connecting shaft 718.

[0044] A first fixed block 74 is fixedly connected to the surface of the first rotating block 72. There are three first fixed blocks 74, which are evenly distributed about the axis of the first rotating block 72. A dual-head motor 75 is fixedly connected inside the first fixed block 74. A second rotating shaft 76 is rotatably connected to one end of the dual-head motor 75. A second spoiler 79 is fixedly connected to the surface of the second rotating shaft 76. A third rotating shaft 77 is rotatably connected to the other end of the dual-head motor 75. A first spoiler 78 is fixedly connected to the surface of the third rotating shaft 77.

[0045] An aeration device 712 is fixedly connected inside the second rotating block 73. A second pipe 713 is fixedly connected to the top of the aeration device 712. A third pipe 714 is fixedly connected to the surface of the second pipe 713. There are six third pipes 714, and the six third pipes 714 are evenly distributed about the axis of the second rotating block 73. An air outlet pipe 715 is fixedly connected to the surface of the third pipe 714.

[0046] The surface of the second rotating block 73 is fixedly connected to an arc-shaped baffle 711 by a fixing rod. There are six arc-shaped baffles 711, which are evenly distributed about the axis of the second rotating block 73. The arc-shaped baffles 711 and the third pipe 714 are staggered about the axis of the second rotating block 73. The bottom of the reaction tank 1 is fixedly connected to a water outlet pipe 716, and an electromagnetic control valve 717 is fixedly connected to the surface of the water outlet pipe 716.

[0047] The biological sludge collection mechanism 8 includes a collection tank 81, which is movably connected to the inside of the reaction vessel 1. A handle 83 is fixedly connected to the surface of the collection tank 81, and a microfiltration membrane 82 is fixedly connected to the inside of the reaction vessel 1.

[0048] During operation, after the landfill leachate flows into the reactor 1, the fourth motor 71 is activated. The activation of the fourth motor 71 drives the fourth rotating shaft 710 to rotate. The rotation of the fourth rotating shaft 710 drives the first rotating block 72 and the second rotating block 73 to rotate together. The rotation of the first rotating block 72 drives the first fixed block 74 to rotate. Then, the dual-head motor 75 is activated. The activation of the dual-head motor 75 drives the second rotating shaft 76 and the third rotating shaft 77 to rotate together, thereby driving the second baffle plate 79 and the first baffle plate 78, which are fixedly connected to the surface, to rotate. The rotation of the second rotating block 73 drives the arc-shaped baffle plate 711 to rotate together. Then, the aeration device 712 is activated. After the aeration device 712 is activated, the gas generated is finally sprayed out from the outlet pipe 715 through the pipe. The aeration device 712 is activated or deactivated by real-time detection and control of the dissolved oxygen meter 5. The intelligent outlet pipe 9 is opened or closed by real-time detection and control of the dissolved oxygen meter 5. During the treatment in the reactor 1, the impurities produced by aerobic microorganisms enter the collection tank 81 through the microfiltration membrane 82 and are collected.

[0049] By setting multiple sets of second baffles 79 and first baffles 78 on the surface of the first fixed block 74, and by starting the dual-head motor 75 to drive the second rotating shaft 76 and the third rotating shaft 77 to rotate, oxygen can be better diffused to all corners of the leachate, avoiding local hypoxia or hyperxia, ensuring that aerobic microorganisms can obtain enough oxygen for metabolic activities throughout the entire treatment area, thereby improving the treatment efficiency of landfill leachate.

[0050] By setting an arc-shaped baffle 711 on the surface of the second rotating block 73 via a fixed rod, after aeration by the air outlet pipe 715, the rotation of the second rotating block 73 drives the arc-shaped baffle 711 to rotate. Initially, when the oxygen content is low, the oxygen floats directly upward through the gap between the arc-shaped baffle 711 and the second rotating block 73. As the oxygen content gradually increases, some oxygen is broken and separated by the through holes on the surface of the arc-shaped baffle 711, further generating a large number of oxygen bubbles, making the oxygen bubbles more dispersed and avoiding local hypoxia or hyperxia. As the oxygen content increases again, some oxygen is further guided along the surface of the arc-shaped baffle 711 to the inner surface of the reaction tank 1, avoiding the problem of uneven local oxygen distribution caused by oxygen supply from the air pipe alone, thereby providing sufficient oxygen for aerobic microorganisms and improving the treatment efficiency of landfill leachate.

[0051] By setting up a collection tank 81 and using the stirring of the second rotating block 73 and the first rotating block 72, impurities produced by aerobic microorganisms can easily pass through the microfiltration membrane 82 and enter the interior of the collection tank 81 for collection, preventing them from accumulating in the reaction tank 1. This avoids inhibiting the growth and metabolism of aerobic microorganisms, ensuring the efficient operation of the biological treatment process, and thus improving the treatment efficiency of landfill leachate.
