[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] This invention provides an agricultural wastewater organic matter adsorption, regeneration, and recycling treatment device. During the wastewater treatment process, organic matter in the wastewater is adsorbed through an activated carbon layer. Then, microorganisms from the microbial ceramic particle layer are blown into the activated carbon layer through an aeration nozzle to decompose the organic matter adsorbed by the activated carbon. This allows the adsorbent to be recycled multiple times, thereby reducing operating costs.

[0023] Figures 1-6 The diagram shown is an overall structural schematic of an embodiment of an agricultural wastewater organic matter adsorption, regeneration, and recycling treatment device according to the present invention. Please refer to [link / reference]. Figures 1-6 This embodiment of an agricultural wastewater organic matter adsorption regeneration and recycling treatment device includes a sedimentation tank 1 as its main body. The sedimentation tank 1 is equipped with an installation frame 3 and a quartz filter layer 9. A coarse filter screen 4 is installed in the middle of the installation frame 3. A composite box 12 and a water storage tank 18 are installed at the rear end of the sedimentation tank 1. A blower 16 is installed at the upper end of the water storage tank 18. An activated carbon layer 13, a microbial ceramsite layer 14 and an air conveying layer are sequentially arranged inside the composite box 12. An aeration nozzle 15 is installed at the bottom of the microbial ceramsite layer 14. The aeration nozzle 15 and the blower 16 are connected through an air conveying pipe.

[0024] The above scheme employs a sedimentation tank 1 for settling agricultural wastewater. Inside, there is an installation frame 3 for mounting and a quartz filter layer 9 for filtration. A coarse filter screen 4 is installed in the middle of the installation frame 3 for preliminary filtration of the agricultural wastewater. Quartz particles 9a are filled inside the quartz filter layer 9 to effectively filter the agricultural wastewater and prevent clogging in subsequent filtration processes. A composite tank 12 and a water storage tank 18 are installed at the rear end of the sedimentation tank 1. The composite tank 12 further treats the agricultural wastewater, and the water storage tank 18 stores the treated agricultural wastewater for easy recycling. Inside the composite tank 12, an activated carbon layer 13, a microbial ceramsite layer 14, and an air conveying layer are sequentially arranged. The activated carbon layer 13 adsorbs impurities present in the agricultural wastewater, and the microbial ceramsite layer 14 further absorbs impurities. The organic matter in the industrial wastewater is decomposed. The air supply layer is used to install air supply pipelines. By setting up aeration nozzles 15, blowers 16 and air supply pipelines, when the activated carbon in the activated carbon layer 13 is saturated, the blower 16 can deliver air sequentially through the air supply pipeline and aeration nozzles 15 into the interior of the composite box 12. By setting the aeration nozzles 15 at the bottom of the microbial ceramic granule layer 14, clogging of the aeration nozzles 15 can be effectively avoided. At the same time, microorganisms on the surface of the porous ceramic granules can be blown into the activated carbon layer 13. The blower 16 continuously provides oxygen, which can effectively improve the activity of microorganisms and shorten the regeneration time. By setting an inoculation box 17 at the top of the composite box 12 and a constant temperature layer on the outer wall of the composite box 12, the inoculation box 17 can replenish the microorganisms in the composite box, and the constant temperature layer can provide a beneficial environment for microorganisms, effectively improving the activity of microorganisms.

[0025] refer to Figure 1 , Figure 2 , Figure 4 The upper end of the water storage tank 18 is connected to a second pump body 19. The second pump body 19 is connected to the inner cavity of the sedimentation tank 1, the inner cavity of the composite tank 12 and the inner cavity of the water storage tank 18 through a second pipe. The output end of the second pipe is connected to a backflushing pipe 20. The backflushing pipe 20 has a king-shaped structure and a backflushing head 20a is provided at the front end of the backflushing pipe 20.

[0026] The above scheme is adopted: by setting up a second pump body 19, a second pipeline and a backwash pipe 20, the second pump body 19 can transport water in the water storage tank 18 through the second pipeline, the backwash pipe 20 and the backwash head 20a, which can realize the backwashing of the quartz filter layer 9, effectively avoiding the clogging of the quartz filter layer 9 and affecting the treatment efficiency. By setting the backwash pipe 20 to a king-shaped structure, the rinsing area can be effectively increased.

[0027] refer to Figure 1 , Figure 2 , Figure 5The upper part of the outer wall of the composite tank 12 is provided with a first pump body 10, and the two ends of the first pump body 10 are connected to the sedimentation tank 1 and the composite tank respectively through the first pipe. The output end of the first pipe is connected to a diversion pipe 11, which has an H-shaped structure and a diversion hole 11a is provided on the outer wall of the diversion pipe 11.

[0028] Using the above scheme: through the first pump body 10 and the first pipeline, the first pump body 10 can draw the pre-treated agricultural wastewater into the composite box 12 for impurity adsorption and organic matter decomposition. By setting the diversion pipe 11 as an H-shaped junction and setting multi-component diversion holes 11a, the agricultural wastewater can be in uniform contact with the activated carbon, effectively avoiding the problem of uneven use of activated carbon.

[0029] refer to Figure 1 , Figure 3 The mounting frame 3 has first drain pipes on both sides, and the first drain pipes are equipped with spiral blades 5 inside.

[0030] The above scheme is adopted: the first sewage pipes for conveying sludge are opened on both sides of the mounting frame 3. The first sewage pipes are equipped with spiral blades 5 for conveying. The upper end of the mounting frame 3 is equipped with a motor 7, and the power output end of the motor 7 is fixedly connected to the spiral blades 5. During the pretreatment of agricultural wastewater, the motor 7 can drive the spiral blades 5 to rotate through the power output end. The spiral blades 5 can convey the sludge at the bottom of the sedimentation tank 1 upward through the first sewage pipe. During the operation, wastewater treatment and sludge cleaning at the bottom of the sedimentation tank can be realized simultaneously, thereby effectively reducing the accumulation of sludge at the bottom.

[0031] refer to Figure 2 The bottom of the mounting frame 3 is equipped with a scraper 6, and the scraper 6 has a triangular structure.

[0032] The above scheme is adopted: by setting scraper 6, in the process of cleaning sludge, by setting telescopic cylinder 8 at the rear end of the installation frame 3 and scraper 6 at the bottom of the installation frame 3, the sludge at the bottom of the sedimentation tank can be centrally treated. By setting scraper 6 as a triangular structure, the sludge can be pushed to both sides, which makes it easier for spiral blades 5 to clean the sludge.

[0033] refer to Figures 1-2 The bottom front end of sedimentation tank 1 has a groove, and a second sewage pipe is installed at one end of the groove.

[0034] The above solution involves setting up a groove and a second drain pipe. During the sewage discharge process, the sludge that is difficult to clean from the bottom of the sedimentation tank can be stored in the groove and then treated again by the second drain pipe.

[0035] refer to Figure 1Sedimentation tank 1 is provided with sedimentation boxes 2 on both sides, and the bottom of sedimentation boxes 2 is inclined. See the figure. Seepage holes are provided on the side wall of sedimentation tank 1.

[0036] The above scheme is adopted: by setting up sedimentation tank 2 and seepage holes, sedimentation tank 2 can perform secondary sedimentation on the discharged sludge, and the wastewater after sedimentation can be returned to the sedimentation tank through the seepage holes.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
