[0023] In order for those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0024] As shown in the drawings, a manure water aerobic biological treatment system comprises: Figs. 1-2

[0025] Embodiment one

[0026] In this embodiment, a plurality of cable hooks 2 are arranged equidistantly on the inner wall of the reaction vessel 1 near the port, and cables 3 are hung between two cable hooks 2 on the same plane, a plurality of falling cables 31 are fixedly arranged on the cables 3, and a plurality of filter balls 32 are fixedly arranged on the falling cables 31 in series, and the filter balls 32 are divided into circular suspended fillers and net-like sponge fillers, and the circular suspended fillers and the net-like sponge fillers on the same falling cable 31 are arranged at intervals. The filter balls 32 provide a large biological attachment area, which is conducive to the growth and reproduction of microorganisms. Microorganisms form a biofilm on the surface of the filter balls, which can more effectively degrade organic matter in manure water. By adjusting the number and layout of the falling cables 31 and the filter balls 32, different scales of manure water treatment requirements can be flexibly adapted. The interval arrangement of the filter balls 32 helps to maintain the smoothness of the water flow and prevent clogging. Under aerobic conditions, microorganisms can more effectively utilize oxygen for respiration, thereby accelerating the degradation of organic matter. The circular suspended fillers and the net-like sponge fillers provide a good attachment environment for microorganisms, which is conducive to the improvement of biological activity

[0027] Embodiment two

[0028] The aeration system in the system is divided into an upper pipe network frame 7, a lower pipe network frame 5, and a plurality of aeration pipes 4 connected in series between the two, wherein:

[0029] The aeration port of the upper pipe network frame 7 faces downward.

[0030] The aeration port of the lower pipe network frame 5 faces upward.

[0031] The aeration port of the aeration pipe 4 is located on the side, i.e., directly opposite the filter ball 32.

[0032] ​Specifically, in this embodiment, the upper pipe network frame 7 and the lower pipe network frame 5 form an oxygen-containing space, and the aeration pipe 4 of the side aeration increases the oxygen content inside this oxygen-containing space, so that the microorganisms are in a high oxygen content environment, which allows the microorganisms to be more active in decomposing the fecal water. The decomposed particulate matter will also be adsorbed onto the filter ball 32, thereby ensuring cleanliness.

[0033] Example 3

[0034] Based on the above embodiments, this embodiment also includes a rotating rod 6 that is rotatably assembled by a bracket erected on the ground. The end of the rotating rod 6 extends to the bottom of the lower pipe network frame 5 and is provided with a water suction plate 61, the inlet of which is located on the side wall.

[0035] Furthermore, the rotating rod 6 is fixedly connected to an arc-shaped rod 62 arranged in a circular array and located above the steel cable 3, and multiple arc-shaped rods 62 have aeration ports facing the same direction on their sides.

[0036] Specifically, in this embodiment, the water pump controlled within the rotating rod 6 draws in water through the suction plate 61 and then ejects it through the arc-shaped rod 62. Due to the high-pressure jetting, the rotating rod 6 continues to rotate, aiming to concentrate particulate matter by utilizing the accumulation capacity of the vortex flow. Furthermore, the suction from the suction plate 61 and the ejection from the arc-shaped rod 62 achieve circulation between the lower and upper layers of sewage. During this circulation process, the sewage passes through an oxygen-containing space, thereby optimizing the aerobic treatment effect.

[0037] It should be noted that a thermometer 8 is installed on the inner wall of the reaction vessel 1 in this embodiment. This thermometer is used to detect whether the temperature inside the reaction vessel 1 is within a suitable temperature for the survival of microorganisms.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
