Description

Technical Field

[0001] This application relates to the technical field of integrated medical treatment devices, and particularly to an integrated biological treatment device for medical wastewater. Background Art

[0002] An integrated biological treatment device for medical wastewater is a device specifically used for treating medical wastewater, aiming to effectively remove harmful substances and pathogens in the wastewater, protect the environment and human health. It mainly includes a pretreatment unit, a biochemical treatment unit, and a post-treatment unit. By adopting advanced biological treatment technologies, it can efficiently remove harmful substances and pathogens in the wastewater. The integrated biological treatment device for medical wastewater plays an important role in modern medical and environmental protection fields. Through reasonable design and operation, it can effectively solve the problems in medical wastewater treatment.

[0003] Currently, the Chinese utility model patent application with the publication date of November 25, 2022, and the publication number of CN 217895331U provides an integrated sewage treatment device for medical institutions, including a fixed frame. One side of the top of the fixed frame is fixedly connected with a treatment tank, and the other side of the top of the fixed frame is fixedly connected with a purification tank. In this integrated sewage treatment device for medical institutions, a discharge cylinder is inserted on one side inside the fixed frame. During use, the solid contaminants deposited from the treated sewage are introduced into the interior of the discharge cylinder through a feeding chute. At the same time, the second driving motor is started, and the second driving motor drives the spiral conveyor shaft to rotate inside the discharge cylinder. The solid contaminants are conveyed to the discharge port side inside the discharge cylinder through the spiral conveyor shaft and discharged, improving the discharge rate of solid pollutants, preventing accumulation and blockage of the discharge pipeline, and preventing accumulation at the bottom end inside the treatment tank from affecting the normal sewage treatment of the device, thus solving the problem of inconvenient discharge of the solid contaminants deposited during treatment.

[0004] In the integrated biological treatment device for medical wastewater in the related art, the solid contaminants deposited from the treated sewage are introduced into the interior of the discharge cylinder through a feeding chute. In the feeding chute, the sewage cannot be completely pumped out through the water suction pipe, and the sewage will be discharged together with the solid contaminants through the discharge port.

[0024] Based on this, in order to improve the technical problem in the related art that due to the incomplete separation of solid particles from the sewage mixture, the sewage and solid particles are discharged together, thereby reducing the efficiency of sewage treatment, the embodiments of the present application provide the following solutions.

[0025] Please refer to Figures 1 to 6 , the embodiments of the present application provide an integrated biological treatment device for medical wastewater. The integrated biological treatment device for medical wastewater includes a pretreatment tank 1, a biochemical treatment tank 2, a filter assembly 3, a disassembly and assembly component 4, and an adjustment component 5. A water inlet pipe 11 is provided on the pretreatment tank 1, a transfer pipe 12 is provided on the pretreatment tank 1, the other end of the transfer pipe 12 is provided on the biochemical treatment tank 2, a water outlet pipe 21 is provided on the biochemical treatment tank 2, the disassembly and assembly component 4 is provided on the pretreatment tank 1, the adjustment component 5 is provided on the biochemical treatment tank 2, and the filter assembly 3 is provided on the pretreatment tank 1.

[0026] In some embodiments, please refer to Figures 1 to 6, the filtering component 3 includes a connecting plate 31, a slide rail 32, a filter plate support 33, a first filter plate 34 and a second filter plate 35. The connecting plate 31 is arranged on the pretreatment tank 1, the slide rail 32 is arranged on the pretreatment tank 1, the filter plate support 33 is arranged on the connecting plate 31, the filter plate support 33 is slidably arranged on the slide rail 32, a fixing seat 39 is arranged on the filter plate support 33, the first filter plate 34 and the second filter plate 35 are arranged on the filter plate support 33 through the fixing seat 39. One end of the connecting plate 31 away from the filter plate support 33 is provided with a first handle 30, the first filter plate 34 and the second filter plate 35 are provided with a second handle 38. The first filter plate 34 is provided with a first filter hole 36, the second filter plate 35 is provided with a second filter hole 37, and the aperture of the first filter hole 36 is larger than that of the second filter hole 37. The disassembly and assembly component 4 includes an installation box 41, a fixing plate 42, an electric push rod 43, a contact plate 44 and a clamping block 45. The installation box 41 is arranged on the pretreatment tank 1, the fixing plate 42 is arranged on the installation box 41, the electric push rod 43 is arranged on the fixing plate 42, the contact plate 44 is arranged on the output rod of the electric push rod 43, the clamping block 45 is arranged at one end of the contact plate 44 away from the electric push rod 43. A connection hole is opened on the installation box 41, a limit hole is opened on the filter plate support 33, and the clamping block 45 is movably arranged on the filter plate support 33 through the connection hole and the limit hole.

[0027] With such a setting, the operator discharges medical wastewater from the water inlet pipe 11. The medical wastewater first passes through the first filter plate 34 for preliminary filtration, and then through the second filter plate 35 for more refined filtration. Then it enters the biochemical treatment tank 2 through the transfer pipe 12. After the filtration is completed, first open the disassembly and assembly component 4, start the electric push rod 43. The electric push rod 43 pushes the abutting plate 44 to slide, and the abutting plate 44 drives the clamping block 45 to slide, and the clamping block 45 slides out of the limiting hole. Thus, the first handle 30 pulls the connecting plate 31, and the connecting plate 31 drives the filter plate support 33 to be taken out through the slide rail 32. Then the filter plate support 33 carries the filter plate through the fixing seat 39, and the filter plate is taken out through the second handle 38, which facilitates the cleaning of the filter plate, thus facilitating the separation of sewage and solid particles and improving the treatment efficiency. The medical wastewater first passes through the first filter plate 34 for preliminary filtration to remove impurities with larger particles, such as larger suspended solids, debris, etc.; then it passes through the second filter plate 35 for more refined filtration to further remove impurities with smaller particles, such as fine suspended solids, some colloidal substances, etc. This multi-stage filtration method can effectively improve the removal efficiency of solid particles in the sewage, significantly improve the quality of the filtered water, and create more favorable conditions for subsequent biochemical treatment. When the filter plate needs to be cleaned, the operator only needs to open the disassembly and assembly component 4 and start the electric push rod 43. The electric push rod 43 pushes the abutting plate 44 to slide, and the abutting plate 44 drives the clamping block 45 to slide, so that the clamping block 45 slides out of the limiting hole, thus unlocking the filter plate support 33. This automatic disassembly and assembly method avoids the inconvenience and tediousness of manually operating the clamping block 45 by hand, improves the disassembly and assembly efficiency, and makes the cleaning work of the filter plate more convenient and fast. When cleaning the filter plate, the filter plate is taken out by operating the disassembly and assembly component 4, and the solid particles intercepted on the filter plate can be thoroughly cleaned. After these solid particles are separated, they will not enter the wastewater treatment process again, thus ensuring the effect of wastewater treatment and ensuring the effective separation of sewage and solid particles.

[0028] In some embodiments, please also refer to Figure 4 , a biochemical treatment component 6 is further provided on the biochemical treatment tank 2. The biochemical treatment component 6 includes a motor support 61, a motor 62 and a biofilm 63. The motor support 61 is provided on the biochemical treatment tank 2, the motor 62 is provided on the motor support 61, the biofilm 63 is provided on the motor 62, the biofilm 63 rotates coaxially with the output shaft of the motor 62, and the biofilm 63 is spiral.

[0029] Set up like this, the sewage reaches the biochemical treatment tank 2 from the transfer pipe 12. The motor 62 drives the biofilm 63 to rotate, realizing the function of uniform stirring. At the same time, the biofilm 63 is spiral, increasing the contact area between the sewage and the biofilm 63. After the sewage enters the biochemical treatment tank 2 from the transfer pipe 12, driven by the motor 62, the biofilm 63 rotates spirally, enabling the sewage to be fully stirred within the entire biochemical treatment tank 2. This stirring effect can evenly distribute the pollutants (such as organic matter, ammonia nitrogen, etc.) in the sewage within the biochemical treatment tank 2, avoiding the situation of too high or too low local pollutant concentration, so as to ensure that microorganisms can contact sufficient and uniform pollutants during the biochemical treatment process, improving the overall efficiency of the biochemical treatment. The uniform stirring enables the microorganisms to be more evenly distributed within the biochemical treatment tank 2 and have more opportunities to contact the pollutants in the sewage. Microorganisms need to fully contact the pollutants to carry out effective metabolic activities and decompose organic pollutants into harmless substances. Therefore, uniform stirring can accelerate the degradation rate of pollutants by microorganisms, shorten the wastewater treatment time, and improve the treatment efficiency. The design of the spiral biofilm 63 greatly increases the surface area of the biofilm 63. When the sewage contacts the spiral biofilm 63, due to the increase in the surface area of the biofilm 63, the contact interface between the two also increases. This means that more microorganisms can contact and react with the pollutants in the sewage, thus increasing the reaction rate and treatment capacity of the biochemical treatment.

[0030] In some embodiments, please also refer to Figures 1 to 3 , the adjustment assembly 5 includes a three-way ball valve 51, an oxygen increaser 52, a nitrogen generator 53 and a connecting pipe 54. A round hole is opened on the biochemical treatment tank 2, and the connecting pipe 54 is arranged on the biochemical treatment tank 2 through the round hole. The three-way ball valve 51 is arranged on the connecting pipe 54, the oxygen increaser 52 is arranged at one end of the three-way ball valve 51, and the nitrogen generator 53 is arranged at the other end of the three-way ball valve 51.

[0031] With such settings, the operator can place the biochemical treatment tank 2 in two different states according to the aerobic or anaerobic living habits of the bacteria in the sewage. When the three-way ball valve 51 connects the biochemical treatment tank 2 and the oxygen increaser 52, the biochemical treatment tank 2 is in a state rich in oxygen. When the three-way ball valve 51 connects the biochemical treatment tank 2 and the nitrogen generator 53, the biochemical treatment tank 2 is in a state lacking oxygen. In this way, aerobic microorganisms can efficiently decompose organic pollutants in the wastewater under sufficient oxygen supply. During the aerobic treatment process, the microorganisms can oxidize ammonia nitrogen to nitrite or nitrate and convert it into nitrogen through the subsequent denitrification process, thus achieving nitrogen removal. At the same time, aerobic microorganisms can also absorb phosphorus in the wastewater, convert it into phosphorus-rich excess sludge, and separate it from the water. Anaerobic microorganisms can treat high-concentration organic wastewater under anoxic conditions. During the anaerobic treatment process, the microorganisms can decompose organic matter into methane and carbon dioxide, generating renewable energy - biogas. Combining aerobic treatment and anaerobic treatment can achieve a more comprehensive wastewater treatment effect. The combination of aerobic treatment and anaerobic treatment can improve the treatment efficiency, reduce the volume of the biochemical tank, save environmental protection investment and reduce daily operating costs. Organic matter, nitrogen, and phosphorus are removed through aerobic treatment, and high-concentration organic matter is removed and biogas is generated through anaerobic treatment, achieving effective removal of various pollutants.

[0032] The implementation principle of the integrated biological treatment device for medical wastewater in the embodiment of the present application is as follows: The operator discharges medical wastewater from the water inlet pipe 11. The medical wastewater first undergoes preliminary filtration through the first filter plate 34 and then more refined filtration through the second filter plate 35. Then it enters the biochemical treatment tank 2 through the transmission pipe 12. After the filtration is completed, first open the disassembly and assembly component 4, turn on the electric push rod 43. The electric push rod 43 pushes the abutting plate 44 to slide. The abutting plate 44 drives the clamping block 45 to slide. The clamping block 45 slides out of the limit hole. Thus, the first handle 30 pulls the connecting plate 31, and the connecting plate 31 drives the filter plate support 33 to be taken out through the slide rail 32. Then the filter plate support 33 carries the filter plate through the fixing seat 39, and the filter plate is taken out through the second handle 38, which facilitates the cleaning of the filter plate, thus facilitating the separation of sewage and solid particles and improving the treatment efficiency. The sewage reaches the biochemical treatment tank 2 from the transmission pipe 12. The motor 62 drives the biological membrane 63 to rotate, realizing the function of uniform stirring. At the same time, the biological membrane 63 is spiral, increasing the contact area between the sewage and the biological membrane 63. Finally, the operator can place the biochemical treatment tank 2 in two different states according to the aerobic or anaerobic living habits of the bacteria in the sewage. When the three-way ball valve 51 connects the biochemical treatment tank 2 and the oxygen increaser 52, the biochemical treatment tank 2 is in a state rich in oxygen. When the three-way ball valve 51 connects the biochemical treatment tank 2 and the nitrogen generator 53, the biochemical treatment tank 2 is in a state lacking oxygen.

[0033] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
