[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1 - Figure 4 As shown in the figure, an integrated aquaculture wastewater treatment device includes an integrated treatment tank 1. The integrated treatment tank 1 is equipped with a residual waste collection tank 2, an aeration mixing tank 3, a microfiltration tank 4, a biological purification tank 5, and a clarifier 6. The multiple tanks are arranged in a rectangular ring around the integrated treatment tank 1. The residual waste collection tank 2, the aeration mixing tank 3, the microfiltration tank 4, the biological purification tank 5, and the clarifier 6 are connected in sequence. The microfiltration tank 4 is equipped with a filtration mechanism 7. An inlet end 8 connected to the residual waste collection tank 2 is provided on the outside of the integrated treatment tank 1. The inlet end 8 extends into the aquaculture tank and is equipped with an inlet pump 9. The microbial purification tank 5 is provided on the outside of the integrated treatment tank 1. The clarifier 6 is connected to the microbial purification tank 5 through a liquid delivery pipe.

[0025] The wastewater first enters the residual sludge collection tank 2 through the inlet 8. In the residual sludge collection tank 2, some of the larger solid pollutants settle naturally to the bottom of the residual sludge collection tank 2 and are discharged into the sludge pipe through the drain valve V1. The wastewater then enters the aeration mixing tank 3 for the next step of treatment.

[0026] In some preferred embodiments, a filter screen is provided at the front end of the water inlet pump 9 to filter out larger solids in the water first.

[0027] Further, referring to Figure 1 The integrated treatment tank 1 is provided with a dissolved oxygen pump 20, the output end of the dissolved oxygen pump 20 is communicated with the aeration mixing tank 3 through an air pipe; the dissolved oxygen pump 20 increases the dissolved oxygen content in the water body, so that the oxygen is dissolved in the water. The aerobic respiration of microorganisms is provided with necessary conditions. The microorganisms use the organic matter in the sewage as a carbon source, and decompose the organic matter into simple substances such as carbon dioxide and water in an aerobic environment, and finally realize the purification of the sewage through a series of oxidation reactions.

[0028] In some preferred embodiments, such as Figure 2 The integrated treatment device further comprises a flocculation tank 22, the flocculation tank 22 is provided with a microbial flocculant adding barrel 23 outside, the flocculation tank 22 is communicated with the aeration mixing tank 3 through a pipeline, and the designed microbial flocculant adding barrel 23 can quantitatively add flocculants. The microbial flocculants in the flocculation tank 22 are added into the aeration mixing tank 3 to flocculate the pollutants therein, and after sedimentation, the sewage is discharged into the sludge pipeline through the blowdown valve V2 for further treatment in the microfiltration tank 4.

[0029] Referring to Figure 3 - Figure 5 The microfiltration tank 4 is provided with a filtering mechanism 7, the filtering mechanism 7 comprises a roller main body 10, the tail end of the roller main body 10 is rotationally connected with the microfiltration tank 4 through a rotating shaft, the outer end of the roller main body 10 is provided with a driving part 11, the roller main body 10 is driven to rotate through the driving part 11, and the water inlet of the microfiltration tank 4 corresponds to the driving part 11;

[0030] The driving part 11 comprises a rotating disc 12 and a large gear 13, a plurality of impact plates 14 are fixed on the outer edge of the rotating disc 12, a driving gear 15 is fixed at the center of the rotating disc 12, rotating shafts which rotationally connect with the outer end of the roller main body 10 are fixed at the centers of the driving gear 15 and the large gear 13, the driving gear 15 and the large gear 13 are arranged in a non-concentric manner, the large gear 13 is engaged with the driving gear 15, a small gear 16 is fixed on the outer side of the large gear 13, and the large gear 13 and the small gear 16 are arranged in a concentric manner;

[0031] Meanwhile, the roller main body 10 is composed of two end plates 17, a plurality of filter cloth filtering frames 18 for mounting filter cloth are fixed between the two end plates 17, an inner tooth ring 19 which is engaged with the small gear 16 is fixed on the inner side of the end plate 17 which is connected with the rotating shaft, and the inner tooth ring 19 is arranged in a concentric manner with the driving gear 15.

[0032] The principle of the filtration mechanism 7 for treating effluent is as follows: First, the water in the aeration mixing tank 3 is pumped into the microfiltration tank 4. The water inlet of the microfiltration tank 4 corresponds to the position of the impact plate 14 of the drive unit 11. The water is transferred from the inlet to the impact plate 14. With the help of the impact plate 14, the rotating disk 12 is driven to rotate, which causes the drive gear 15 to drive the large gear 13 to rotate. Then, with the help of the small gear 16 meshing with the internal gear ring 19, the roller body 10 rotates accordingly. The solids in the sewage are filtered and retained in the filter cloth on the filter cloth filter frame 18.

[0033] In an optional embodiment, a flushing water pipe (not shown in the figure) is provided above the filter cloth filter frame 18, and an opening is provided at one end of the roller body 10 away from the drive part 11. The opening is set as a solids collection port and is connected to the aeration mixing tank 3. By opening the flushing water pipe, the centrifugal force of the roller body 10 when it rotates is used to gather the solids and let them fall back into the aeration mixing tank 3 through the solids collection port, and then discharge them into the sludge pipe through the drain valve V2.

[0034] In an alternative embodiment, the filter mechanism 7 is configured such that one end of the drive unit 11 is higher than the end of the solids collection port, thereby facilitating the collection and discharge of solids.

[0035] It should be noted that the drive unit 11 in this design uses a star gear system, which amplifies the overall transmission ratio of the system through two stages, ultimately amplifying the torque of the relatively small fluid impact force acting on the impact plate 14. By rationally designing the transmission ratio of the gear system, the required torque amplification effect can be achieved, realizing impurity separation while also eliminating noise generated by fluid noise and mechanical vibration.

[0036] It should also be noted that the filter cloth on the filter cloth filter frame 18 can be fully wrapped or partially wrapped.

[0037] In this scheme, the water filtered by the microfiltration tank 4 is pumped to the biological purification tank 5 by a submersible pump within the microfiltration tank. Suspended carrier packing is installed in the biological purification tank 5 to enrich the biofilm, where microorganisms degrade organic matter in the wastewater. In a preferred embodiment, a branch pipe is connected from the dissolved oxygen pump 20 to pressurize air into the water in the biological purification tank 5 (not shown in the figure), allowing the oxygen in the air to fully contact the water, thereby dissolving oxygen in the water, increasing the dissolved oxygen content, and further degrading organic matter.

[0038] In some preferred embodiments, such as Figure 1The integrated treatment tank 1 is equipped with an ultraviolet germicidal lamp 21. The liquid in the microfiltration tank 4 is connected to the ultraviolet germicidal lamp 21 through the outlet pipe, where it is sterilized. After sterilization, the liquid then enters the biological purification tank 5 through a water pipe. The solids treated in the biological purification tank 5 are concentrated at the bottom of the tank and discharged into the sludge pipe through the drain valve V3. The treated liquid enters the clarification tank 6.

[0039] In this scheme, clarifier 6 functions as a sedimentation tank, separating biological sludge, which is then discharged from V4 into the sludge pipeline. Clarifier 6 clarifies the treated water. To enhance the treatment effect and ensure the effluent meets the quality requirements for circulating water, an enhanced treatment section can be connected, such as... Figure 2 As shown in the diagram, section T5 in this scheme is designated as a biofilm treatment section to enhance the treatment of the effluent from clarifier 6. The biofilm treatment section purifies the water, improves the water quality of the aquaculture pond, and enhances the quality of farmed aquatic products. In the biofilm treatment section, a dissolved oxygen pump 20 pressurizes air into the water, ensuring sufficient contact between the oxygen in the air and the water. This allows oxygen to dissolve into the water, increasing the dissolved oxygen content, degrading organic matter, and achieving the goal of water purification.

[0040] It should be noted that the integrated equipment in this solution can be a standalone set of equipment, including a residual waste collection tank 2, an aeration mixing tank 3, a microfiltration tank 4, a biological purification tank 5, and a clarifier tank 6, a dissolved oxygen pump 20, a microbial flocculant dosing tank 23, and a metering pump. Through an internally installed intelligent electronic control device, the operation of the metering pump is controlled according to the suspended solids concentration of the influent, and the dosage of microbial flocculant is adjusted.

[0041] In this solution, the wastewater is filtered and treated by the residual sludge collection tank 2, aeration mixing tank 3, microfiltration tank 4, biological purification tank 5, and clarification tank 6 designed in the integrated treatment tank 1. This effectively separates the suspended solids in the wastewater. Compared with the traditional sedimentation treatment method, the cycle is shorter, and the residual sludge collection tank 2, aeration mixing tank 3, microfiltration tank 4, biological purification tank 5, and clarification tank 6 are arranged in a rectangular pattern, requiring a small footprint.

[0042] In this design, to improve the operational stability and reliability of the filter mechanism 7, the rotating disk 12, drive gear 15, large gear 13, and small gear 16 are all made of polyoxymethylene (POM) material. POM material has excellent mechanical properties, high impact strength, and is very beneficial in terms of self-slip properties, wear resistance, creep resistance, and fatigue strength. It also has stable chemical properties and is relatively stable to both inorganic and organic chemicals. Using the above materials to make the gear structure can significantly improve the operational performance and reliability of the filter assembly of this invention, and reduce maintenance and usage costs.

[0043] Meanwhile, in order to improve the strength of the connecting structure, the rotating shaft, the end plate 17 and the filter cloth filter frame 18 in the scheme are made of metal materials, preferably stainless steel materials.

[0044] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the application belong to the scope protected by the utility model.
