[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Example

[0034] See also Figure 1-6 A sewage treatment device based on microbial enhancement includes: a pretreatment cylinder 1, a cleaning component 2 and a monitoring feedback component 3, a grille is installed in the pretreatment cylinder 1, and a water pump is installed in the pretreatment cylinder 1, one end of the pretreatment cylinder 1 is fixedly connected to a transmission pipe 11 connected thereto, and a cleaning component 2 is arranged at the bottom of the transmission pipe 11; a cleaning component 2, the cleaning component 2 includes a cleaning cylinder 21, and one end of the cleaning component 2 is connected to a collecting cylinder 5 through a pipeline, a stirring cover 22 is fixedly connected to the bottom of the transmission pipe 11, and the stirring cover 22 is arranged at the center of the cleaning cylinder 21, and a plurality of evenly distributed monitoring feedback components 3 are arranged in the cleaning cylinder 21; a monitoring feedback component 3, the monitoring feedback component 3 includes an abutment cover 31, and a plurality of abutment covers 31 abut against the abutment cover 22, and a protection component 4 is installed in the middle of the plurality of monitoring feedback components 3 and at the bottom of the cleaning cylinder 21.

[0035] Among them, the combined structure of the stirring cover 22, the stirring rod 23 and the servo motor can accurately adjust the flow state of sewage to ensure sufficient contact between the sewage and the microbial attachment block 35, avoid the formation of dead zones, and avoid the influence of sludge deposition on the bottom of the equipment; the dynamic collaborative design of the float block 34 and the microbial attachment block 35 increases the contact area with the sewage through shaking, further improving the treatment efficiency; the structural design of the monitoring rod 33 and the counterweight box 32 realizes accurate monitoring of the dynamic state of the microbial attachment block, which is convenient for timely adjustment of the biofilm thickness; the protective component 4 shields the bottom sediment with a sealing cloth to prevent it from being disturbed and mixed into the water body due to stirring. The optimized design of the overall structure ensures the efficient operation, stability and adaptability of the sewage treatment system, can adapt to the needs of complex sewage treatment environments, and prolongs the service life of the device.

[0036] The bottom end of the stirring cover 22 is fixedly connected to a servo motor, and an output end of the servo motor is fixedly connected to a stirring rod 23 , which is disposed in the cleaning cylinder 21 .

[0037] Among them, the bottom end of the stirring cover 22 is fixedly connected to the servo motor, and the output end of the servo motor is fixedly connected to the stirring rod 23. The stirring rod 23 is arranged in the cleaning barrel 21. Through the drive of the servo motor, the stirring rod 23 can achieve precise rotation speed and direction adjustment according to needs, so as to control the flow state of sewage inside the cleaning barrel 21, ensure sufficient contact between the sewage and the microbial attachment block 35, and improve the pollutant degradation efficiency. The design of the stirring rod 23 can adopt a spiral, blade or sawtooth structure. By optimizing the angle and shape of the stirring blade, a uniform flow field can be formed in the sewage to avoid dead zones. At the same time, it can effectively prevent sludge or impurities from being deposited at the bottom of the cleaning barrel 21 and affecting the treatment effect.

[0038] The application of the servo motor makes the operation of the stirring rod 23 more flexible and efficient. The servo motor dynamically adjusts the operating parameters of the stirring rod 23, such as speed, direction and working time, through a precise control system. It can not only meet the needs of different sewage treatment stages, but also effectively reduce energy consumption and extend the service life of the equipment. In addition, the high-precision characteristics of the servo motor can ensure that the stirring rod 23 maintains stable operation in a complex sewage environment and avoid the biofilm on the microbial attachment block 35 from falling off due to excessive stirring.

[0039] The combination of the stirring cover 22, the stirring rod 23 and the servo motor significantly enhances the sewage treatment capacity inside the cleaning cylinder 21. The rotation of the stirring rod 23 can not only accelerate the contact reaction between the sewage and the attached microorganisms, but also promote the uniform distribution of dissolved oxygen in the cleaning cylinder 21, providing a good metabolic environment for aerobic microorganisms. Through this design, the device can achieve efficient sewage treatment in a limited space, greatly improve the treatment effect, and reduce the system operation cost.

[0040] A monitoring rod 33 is slidably connected to the middle of the abutting cover 31 , a counterweight box 32 is fixedly connected to the top of the monitoring rod 33 , and a sealing bolt is threadedly connected to the counterweight box 32 .

[0041] The outer surface of the monitoring rod 33 is engraved with a scale.

[0042] Among them, a monitoring rod 33 is slidably connected to the middle of the abutment cover 31, a counterweight box 32 is fixedly connected to the top of the monitoring rod 33, and a sealing plug is threadedly connected to the counterweight box 32. Through the weight design of the counterweight box 32, water or sand can be injected into it, which can effectively balance the buoyancy of the microorganism attachment block 35 in the initial stage of the device, so that it can be kept on the same horizontal line in the water body, thereby ensuring that each microorganism attachment block 35 is at a consistent working height, ensuring the uniformity of contact between the sewage and the microorganism attachment block 35, and avoiding fluctuations in treatment efficiency due to position differences.

[0043] The outer surface of the monitoring rod 33 is engraved with a scale, which can intuitively reflect the height change of the microorganism attachment block 35 in the water body. As the biofilm on the microorganism attachment block 35 gradually thickens, its weight will increase accordingly, causing the position of the monitoring rod 33 to change. By observing the reading of the scale, the growth of the biofilm can be clearly judged. When the scale changes beyond the predetermined range, the microorganism attachment block 35 can be cleaned or processed in time to ensure the efficient operation of the system.

[0044] The threaded sealing bolt design on the counterweight box 32 further enhances the adjustability and sealing of the system. Through the sealing bolt, the weight of the filler in the counterweight box 32 can be easily adjusted, so as to flexibly adapt to the buoyancy requirements under different sewage treatment conditions. The scope of application of the device is extended, and the operating stability and maintenance convenience of the system are significantly improved. Through this design, the device can realize accurate monitoring and management of the dynamic state of the microbial attachment block 35, effectively improving the sewage treatment efficiency.

[0045] A floating block 34 and a microorganism attachment block 35 are fixedly connected to the bottom end of the monitoring rod 33 . The floating block 34 is arranged on the upper side of the microorganism attachment block 35 , and the material of the floating block 34 is set to be polyethylene.

[0046] A plurality of distributed filling holes are provided on the microorganism attachment block 35 , and the filling holes are filled with inner filling blocks. The hole diameter of the filling holes is set to 5-10 mm, and the material of the inner filling blocks is set to polypropylene or ceramic material.

[0047] Among them, a float block 34 and a microorganism attachment block 35 are fixedly connected to the bottom end of the monitoring rod 33. The float block 34 is arranged on the upper side of the microorganism attachment block 35, and the material of the float block 34 is set to polyethylene. The design of the float block 34 is mainly used to provide additional buoyancy, so that the microorganism attachment block 35 is in a suspended or semi-suspended state in the water body. At the same time, through its stable buoyancy characteristics, the position of the microorganism attachment block 35 in the treatment device is kept stable to avoid displacement or sedimentation due to water flow disturbance. The polyethylene material is very suitable for use in sewage treatment environments due to its excellent corrosion resistance, light weight, high buoyancy and long-term underwater stability.

[0048] The design of the float block 34 not only provides sufficient buoyancy so that the microbial attachment block 35 can always be in a suspended or semi-suspended state, but also has an important function, that is, when affected by the water flow and the stirring rod 23 in the water body, the float block 34 can drive the monitoring rod 33 and the microbial attachment block 35 to produce a slight shaking as a whole. Through this dynamic movement, the microbial attachment block 35 can continuously change the contact angle and position with the sewage, thereby significantly increasing the collision area between the microbial attachment block 35 and the sewage and improving the treatment effect. This shaking design forms a synergistic effect with the action of the stirring rod 23, making the device more efficient and uniform during the sewage treatment process.

[0049] The microbial attachment block 35 is provided with a plurality of distributed filling holes. The design of the holes can significantly increase the specific surface area of ​​the microbial attachment block, provide more space for the attachment and growth of microorganisms, and help to form a stable biofilm, thereby improving the sewage treatment efficiency. The pore size of the filling holes is set to 5-10mm. This range can ensure that the sewage flows smoothly through the holes, while providing a good attachment environment for the microorganisms, avoiding blockage caused by too small pores or reduced attachment effect due to too large pores. The filling holes are filled with inner filling blocks, and the material of the inner filling blocks is set to polypropylene or ceramic. Polypropylene, as a polymer material, has strong corrosion resistance, light weight and good microbial attachment, which facilitates the attachment and growth of microorganisms when sewage flows. The ceramic material has excellent effects in treating complex sewage due to its high specific surface area, high temperature resistance, acid and alkali resistance and strong stability, and can provide a more ideal growth environment for microorganisms.

[0050] The shaking of the floating block 34 under the action of the stirring rod 23 can force the sewage to continuously pass through the microorganism attachment block 35 in different directions, so that the sewage and the microorganisms are in more complete contact, thereby accelerating the degradation of organic matter and improving the treatment efficiency. In addition, this shaking effect can also effectively prevent the problem of local excessive thickness of the biofilm on the microorganism attachment block 35. Through dynamic shaking, the surface of the biofilm can be continuously washed by water flow, avoiding the problem of reduced treatment efficiency or local anaerobic oxidation caused by excessively thick biofilm.

[0051] Through the coordinated work of the floating block 34 and the microorganism attachment block 35, the entire system can form an efficient microorganism treatment module in the water body. The floating block 34 ensures that the microorganism attachment block 35 is in the best working position, and the design of the filling hole and the inner filling block further improves the treatment efficiency of the microorganisms, providing excellent performance and long-term stability for the sewage treatment device. Through the shaking design of the floating block 34 and the combined action of the stirring rod 23, the device not only realizes the dynamic and efficient contact between the sewage and the microorganism attachment block 35, but also optimizes the uniformity of sewage treatment, so that the overall treatment efficiency is significantly improved. This synergistic design makes the device more suitable for coping with complex sewage environments and meeting the needs of efficient treatment.

[0052] The protection assembly 4 includes a fixing ring 42 fixedly connected to the inner wall of the cleaning cylinder 21 , a pair of fixing plates 43 are fixedly connected to the inner wall of the fixing ring 42 , and a fixing disk 41 is installed in the middle of the pair of fixing plates 43 .

[0053] The bottom end of the fixed disk 41 is fixedly connected to a sealed shell, a micro motor is installed in the sealed shell, the output end of the micro motor is fixedly connected to a plurality of evenly distributed rotating rods 44, one end of the rotating rod 44 is connected to a sealing cloth, and one end of the sealing cloth is connected to the fixed plate 43.

[0054] Among them, the main function of the protection component 4 is to effectively solve the problem of sediment generated at the bottom during the sewage treatment process by microorganisms. Since these sediments may be disturbed and re-mixed into the water body due to the operation of the stirring rod 23, thereby affecting the efficiency of sewage treatment, a protection mechanism is designed to shield the bottom sediment during stirring. When the stirring rod 23 is working, the micro motor is started to drive multiple rotating rods 44 to rotate synchronously, and the rotating rods 44 then pull the sealing cloth to unfold, completely shielding the sediment at the bottom of the cleaning cylinder 21 to prevent the sediment from being swept into the water flow due to stirring, thereby ensuring the stability and efficiency of the sewage treatment process.

[0055] The sealing cloth is designed with flexible materials, which can be flexibly unfolded and retracted under the action of the rotating rod 44. At the same time, it has good sealing and corrosion resistance to adapt to the complex conditions of the sewage treatment environment. The other end of the sealing cloth is connected to the fixed plate 43, which provides support and restraint to ensure that the sealing cloth can completely cover the bottom sedimentation area when unfolded without leaving any dead corners.

[0056] Through the coordinated action of the fixing ring 42, the fixing plate 43, the fixing disk 41 and the micro motor, the protection component 4 can respond quickly when needed, effectively preventing the bottom sediment from being disturbed and mixed in the water body. At the same time, after the stirring work is completed, the micro motor reversely drives the rotating rod 44 to reset and retract the sealing cloth to the initial position, without affecting the normal operation and subsequent maintenance of the equipment.

[0057] It significantly improves the efficiency and stability of sewage treatment equipment in treating sewage containing sediment, while avoiding equipment blockage or reduced treatment effect caused by secondary mixing of sediment, providing better protection for sewage treatment.

[0058] At the same time, in order to improve the efficiency of sewage treatment, an aeration device is also required inside the device. The aeration device releases gas evenly inside the cleaning cylinder 21, dissolves oxygen in the air into the water body, provides sufficient oxygen support for aerobic microorganisms, and promotes their metabolic activities and the decomposition of organic pollutants. At the same time, the aeration device can further enhance the fluidity of the water body, form a synergistic effect with the action of the stirring rod 23, optimize the distribution of dissolved oxygen in the sewage, and avoid local anaerobic phenomena caused by uneven oxygen distribution. In addition, the aeration process can also effectively prevent excessive deposition of sludge and impurities at the bottom, and improve the uniformity and overall efficiency of sewage treatment. Through the introduction of the aeration device, a more ideal working environment is provided for microorganisms, the operating performance of the sewage treatment device is further enhanced, and a more efficient and stable treatment effect is ensured. The aeration device belongs to the prior art and will not be repeated here.

[0063] S4: The position of the microbial attachment block 35 and the growth of the biofilm are monitored in real time by the monitoring feedback component 3, and the buoyancy change is balanced by the adjustment function of the counterweight box 32.

[0064] S5: During the operation of the stirring rod 23, the micro motor in the protection component 4 is started to drive the rotating rod 44 to rotate and unfold the sealing cloth to cover the sediment at the bottom of the cleaning cylinder 21 to prevent the sediment from being re-mixed into the water body due to water flow disturbance, thereby ensuring the stability of sewage treatment;

[0065] S6: After the treatment is completed, the sewage enters the collection cylinder 5 through the cleaning component 2, and is discharged or recycled after further purification to ensure that the effluent water quality meets the discharge standards.
