Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a medical wastewater treatment device. Background Technology

[0002] With the rapid development of the medical industry, the discharge of medical wastewater is increasing daily. Medical wastewater contains large amounts of pathogens, organic matter, and other harmful substances. If discharged directly without effective treatment, it will pose a serious threat to the environment and human health. Therefore, medical wastewater treatment equipment has become a key component in ensuring environmental safety. While existing medical wastewater treatment processes, including conditioning, anaerobic, aerobic, and disinfection, can remove most pollutants, the treated water still presents some problems. Firstly, the treated water often retains an odor, which may originate from incompletely decomposed organic matter or byproducts generated during disinfection. This not only affects the sensory quality of the effluent but may also indicate the presence of harmful substances. Secondly, the treated water may contain residual impurities, such as tiny suspended solids or colloidal substances. If discharged into the environment, these impurities could impact aquatic ecosystems and fail to meet stricter water quality discharge standards.

[0003] Furthermore, traditional methods for removing odors and filtering impurities have many drawbacks. Some devices install filters inside the wastewater treatment tank to remove impurities, but this method faces difficulties in cleaning and replacing the filters during actual use. Because the filters are installed inside the wastewater treatment tank, cleaning requires stopping the entire treatment process, consuming a lot of time and manpower, and the cleaning effect is often unsatisfactory. After long-term use, the filtration performance of the filters will decrease significantly. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6The illustrated medical wastewater treatment device includes a wastewater treatment tank 3 and multiple drain pipes 1 located at the bottom front end of the wastewater treatment tank 3. Each drain pipe 1 is connected to a wastewater discharge pipe 2 at its front end. Multiple feed windows 6 are equidistantly arranged at the top of the wastewater treatment tank 3, and each feed window 6 has a sealing cap 7 fitted over its top opening. A wastewater inlet 9 is located at the upper side of the center of the left end of the wastewater treatment tank 3, and a clean water outlet 5 is located at the lower side of the center of the right end of the wastewater treatment tank 3. Inside the wastewater treatment tank 3, from left to right, are arranged a regulating chamber 10, an anaerobic treatment chamber 11, an aerobic treatment chamber 12, and a clean water disinfection chamber 13. Multiple feed windows 6 are located above the centers of the regulating chamber 10, anaerobic treatment chamber 11, aerobic treatment chamber 12, and clean water disinfection chamber 13, respectively. These feed windows 6 are connected to the interiors of each chamber. The inlet 21 is connected to the interior of the clean water disinfection chamber 13. A transfer pump 16 is fixed to the lower interior of the centers of each of the regulating chamber 10, anaerobic treatment chamber 11, and aerobic treatment chamber 12 via a frame. Wastewater from these chambers is transported to the next treatment chamber via the transfer pump 16. Water inlet 9 is connected to the interior of regulating chamber 10. Medical wastewater flows into regulating chamber 10 from wastewater inlet 9 located above the center of the left end of wastewater treatment tank 3. The function of regulating chamber 10 is to initially regulate the flow rate and concentration of wastewater, making the subsequent treatment process more stable. Inside the lower center of regulating chamber 10, a conveying pump 16 fixed to the frame transports the wastewater to the next stage treatment chamber—anaerobic treatment chamber 11. At the same time, an aeration pump 8 located above the rear center of regulating chamber 10 draws in air through the air inlet and delivers the air through the air outlet via air supply pipe 17 to the loop aeration pipe 14, and then... Multiple aeration heads 15 at the top of the aeration pipe aerate the wastewater, increasing the dissolved oxygen in the wastewater and preparing it for subsequent treatment. After the wastewater enters the anaerobic treatment chamber 11, the organic matter in the wastewater is decomposed by anaerobic microorganisms. Anaerobic treatment can remove most of the organic matter and convert it into gases such as methane and carbon dioxide. The sewage pipe 1 at the bottom front of the anaerobic treatment chamber 11 is used to discharge the waste residue and other waste generated during the treatment process. This waste residue is discharged from the device through the waste discharge pipe 2, while the anaerobic wastewater is transported to the aerobic treatment chamber 12 through the transfer pump 16 at the bottom of the center.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an aeration pump 8 is installed above the rear side of the center of both the regulating chamber 10 and the aerobic treatment chamber 12. The aeration pump 8 is fixed to the outer wall of the top of the wastewater treatment tank 3. Multiple sewage pipes 1 are located at the bottom front of the regulating chamber 10, the anaerobic treatment chamber 11, and the aerobic treatment chamber 12, respectively, and are connected to the interior of each of the three chambers. A loop-shaped aeration pipe 14 is installed at the bottom of both the regulating chamber 10 and the aerobic treatment chamber 12. Multiple aeration heads 15 are equidistantly arranged at the top of each loop-shaped aeration pipe 14. Each of the two aeration pipes 14 has an air supply pipe 17 connected to the top of its rear center. Each of the two aeration pumps 8 has an air inlet at its right end and an air outlet at its bottom. The tops of the two air supply pipes 17 are connected to the air outlets at the bottom of the two aeration pumps 8, respectively. In the aerobic treatment chamber 12, aerobic microorganisms utilize dissolved oxygen in the wastewater to further decompose the remaining organic matter. The aerobic treatment chamber 12 is also equipped with aeration pumps 8, and through an aeration system similar to that in the regulating chamber 10, sufficient oxygen is supplied to the wastewater to enhance the decomposition effect of organic matter. Waste generated during the treatment process is discharged through the drain pipe 1 at the bottom front. The wastewater after aerobic treatment is transported to the clean water disinfection chamber 13 by the transfer pump 16. The wastewater entering the clean water disinfection chamber 13 is disinfected to kill bacteria, viruses and other pathogens. The clean water treated in the clean water disinfection chamber 13, after disinfection, flows into the odor removal and filtration device 4 through the inlet 21 at the right end of the wastewater treatment tank 3, and is finally discharged through the clean water outlet 5. Throughout the entire treatment process, multiple material windows 6 are equidistantly set at the top of the wastewater treatment tank 3. Materials required for treatment are added to the regulating chamber 10, anaerobic treatment chamber 11, aerobic treatment chamber 12, and clean water disinfection chamber 13. The sealing cover 7, which is fitted onto the top opening of the material window 6, prevents external impurities from entering. Meanwhile, the sealing box cover 19 of the odor removal and filtration device 4 is connected to the cube treatment box 18 by fixing screws 20. The sealing gasket 22 ensures the sealing effect. When replacing the activated carbon filter screen 24, it is only necessary to open the sealing box cover 19 to carry out the operation, which is convenient and quick, avoiding the cleaning and replacement difficulties caused by installing a filter screen inside the wastewater treatment tank 3.

[0027] like Figure 1 , Figure 5 and Figure 6As shown, an odor removal and filtration device 4 is connected between the purified water outlet 5 and the wastewater treatment tank 3. The odor removal and filtration device 4 includes a rectangular treatment box 18, a sealed cover 19, fixing screws 20, and a sealing gasket 22. The rectangular treatment box 18 is sealed and fixed to the bottom right end of the wastewater treatment tank 3, and the top of the rectangular treatment box 18 is open. A sealed cover 19 is located at the top of the rectangular treatment box 18, and a sealing gasket 22 is also attached and fixed to the bottom outer wall of the sealed cover 19. The sealing gasket 22 can completely fit against the top outer wall of the rectangular treatment box 18. The sealed cover 19 and the rectangular treatment box 18 are fixedly connected by multiple fixing screws 20. The rectangular treatment box 18 is sealed and fixed to the bottom right end of the wastewater treatment tank 3. This connection method ensures that the treated purified water can stably flow into the device. The top of the rectangular treatment box 18 is open. The device is equipped with a sealing cover 19. A sealing gasket 22 is attached to the outer wall of the bottom of the sealing cover 19. After the sealing cover 19 is fixed to the cuboid treatment box 18 by multiple fixing screws 20, it can completely fit against the outer wall of the top of the cuboid treatment box 18. This design effectively prevents water leakage and the entry of external impurities during the treatment process, ensuring stable operation of the device. In addition, the U-shaped sealing frame 23 is fixed to the sealing cover 19 by screws. This design has great advantages in device maintenance. Simply unscrew the fixing screws 20 of the sealing cover 19 and open the sealing cover 19 to easily inspect, clean or replace the U-shaped sealing frame 23 and the activated carbon filter 24 inside. The device can be kept running continuously and efficiently without complicated operations, effectively solving the problem of traditional filter screens being difficult to clean and replace.

[0028] like Figure 1 , Figure 5 and Figure 6As shown, the odor removal and filtration device 4 also includes an inlet 21, a U-shaped sealing frame 23, and an activated carbon filter 24. The inlet 21 is located inside the center of the left end of the cuboid treatment tank 18, and it communicates with the inside of the right end of the wastewater treatment tank 3. An outlet is located inside the right end of the cuboid treatment tank 18, and the purified water outlet 5 is fixed outside the right end of the outlet. The treated clean water flows into the odor removal and filtration device 4 from the right end of the wastewater treatment tank 3, specifically through the inlet 21 located inside the center of the left end of the cuboid treatment tank 18. The outlet located inside the right end of the cuboid treatment tank 18 discharges the treated clean water, and the purified water outlet 5 is fixed outside the right end of the outlet, ensuring that the treated clean water can be smoothly transported to subsequent stages. Multiple U-shaped sealing frames 23 are fixed to the bottom of the sealing tank cover 19 by screws. The frames of the multiple U-shaped sealing frames 23 are all fixed inside. Multiple activated carbon filters 24 are fixed inside the cubic treatment box 18. The U-shaped sealing frame 23 is vertically inserted downwards. After the sealing box cover 19 is fixed to the top of the cubic treatment box 18 by fixing screws 20, the bottom and front and rear outer walls of the multiple U-shaped sealing frames 23 are respectively attached to the bottom and front and rear inner walls of the cubic treatment box 18, thus forming a relatively independent and closed filtration space. Multiple activated carbon filters 24 are fixed inside the frames of the multiple U-shaped sealing frames 23. The activated carbon filters 24 have rich pore structure and strong adsorption capacity. When clean water enters the device from the inlet 21, as it flows through the activated carbon filters 24, the activated carbon filters 24 absorb residual odor substances in the clean water on the one hand, and intercept fine impurity particles suspended in the clean water on the other hand, thereby realizing the functions of removing odor and filtering impurities from the clean water.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
