Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a novel high-efficiency purification device for treating medical wastewater. Background Technology

[0002] Medical wastewater contains high concentrations of pathogenic bacteria, viruses, and chemical agents, requiring strict and specialized treatment before discharge. In practice, large amounts of hypochlorous acid solution are often added to disinfect the wastewater, effectively inactivating pollutants such as ammonia nitrogen and bacteria. However, hypochlorous acid disinfection leaves a large amount of chlorine residue in the wastewater. If subsequent treatment fails to effectively remove these chlorine components, it may lead to new environmental pollution problems.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a novel, highly efficient purification device for treating medical wastewater, which can effectively eliminate ammonia and bacteria in medical wastewater.

Multiple ultraviolet disinfection lamps are suspended in the ultraviolet photocatalytic tank. The biological packing tank is equipped with biological packing material and an aeration mechanism. The body is equipped with a dosing mechanism, which includes a hypochlorous acid tank and a reducing agent tank. The dosing mechanism is equipped with a first pump and a second pump. The first pump is connected to the hypochlorous acid tank and the disinfection tank, respectively, and the second pump is connected to the reducing agent tank and the reduction tank, respectively.

[0006] In one or more embodiments, the dosing mechanism has a residual chlorine monitor, and the second pump dispenses the reducing agent according to the residual chlorine value of the residual chlorine monitor.

The lamp holder is provided with a threaded joint, the quartz lamp tube is screwed to the threaded joint and forms a lamp cavity, and the ultraviolet lamp body is disposed in the lamp cavity.

[0008] In one or more embodiments, the end face of the threaded connector is provided with an e27 thread, the ultraviolet lamp body is connected to the e27 thread to draw power, and the lamp holder is provided with a power cord on the other side of the threaded connector.

[0009] In one or more embodiments, the lamp holder is provided with a sealing ring at the threaded joint, and the sealing ring is pressed against the quartz lamp tube when it is connected to the threaded joint.

[0012] The beneficial effects of this invention are as follows: By sequentially integrating multiple treatment units, including ultraviolet photocatalysis, biodegradation, physical precipitation, chemical disinfection, and reduction neutralization, into a single unit, a continuous, efficient, and multi-stage synergistic deep purification process is constructed. This device not only effectively kills pathogenic bacteria, viruses, and other harmful microorganisms in medical wastewater, but also efficiently degrades organic matter, removes suspended solids, and specifically removes residual chlorine after disinfection, ultimately achieving comprehensive and thorough purification of medical wastewater and ensuring that the effluent meets safety standards.

[0015] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0016] Please refer to the appendix. Figure 1This invention provides a novel, highly efficient purification device for treating medical wastewater. It includes a main body containing, sequentially connected components: an ultraviolet photocatalytic tank 1, a biological packing tank 2, an inclined tube sedimentation tank 3, a disinfection tank 4, and a reduction tank 5. Multiple ultraviolet disinfection lamps 6 are suspended in the ultraviolet photocatalytic tank 1. The biological packing tank 2 is equipped with biological packing material and an aeration mechanism. The main body includes a dosing mechanism comprising a hypochlorous acid tank 8 and a reducing agent tank 9. The dosing mechanism also includes a first pump and a second pump. The first pump is connected to both the hypochlorous acid tank 8 and the disinfection tank 4, while the second pump is connected to both the reducing agent tank 9 and the reduction tank 5. Both pumps are conventional water pumps. This solution integrates multiple treatment units, including ultraviolet photocatalysis, biodegradation, physical precipitation, chemical disinfection, and reduction neutralization, into a single main body, constructing a continuous, efficient, and multi-stage synergistic deep purification process. This device can not only effectively kill pathogenic bacteria, viruses and other harmful microorganisms in medical wastewater, but also efficiently degrade organic matter, remove suspended solids, and specifically remove residual chlorine after disinfection, ultimately achieving comprehensive and thorough purification of medical wastewater and ensuring that the effluent water quality meets safety standards.

[0017] The dosing mechanism includes a residual chlorine monitor 10, and the second pump dispenses the reducing agent based on the residual chlorine reading from the monitor 10. By linking the residual chlorine monitor 10 with the second pump, precise and automatic dosing of the reducing agent is achieved. This structure can dynamically adjust the amount of reducing agent based on real-time residual chlorine readings, ensuring sufficient removal of residual chlorine while avoiding agent waste or secondary pollution, thus improving the system's economic efficiency and intelligence.

[0018] The ultraviolet disinfection lamp 6 includes a lamp holder 61, a quartz lamp tube 62, and an ultraviolet lamp body 63. The lamp holder 61 is provided with a threaded connector 64. The quartz lamp tube 62 is screwed to the threaded connector 64 and forms a lamp cavity. The ultraviolet lamp body 63 is located in the lamp cavity. Since the ultraviolet disinfection lamp 63 is used in water, the surface of the quartz lamp tube 62 is prone to scale buildup. This structure allows for easy disassembly and replacement of the quartz lamp tube 62. The disassembled quartz lamp tube 62 can be disinfected with a descaling agent and saved for future replacement.

[0019] The threaded connector 64 has an e27 threaded opening on its end face. The ultraviolet lamp body 63 is connected to the e27 threaded opening to draw power. The lamp holder 61 has a power cord 65 on the other side of the threaded connector 64, which facilitates the disassembly and replacement of the damaged ultraviolet lamp body 63 in the future.

[0020] The lamp holder 61 is provided with a sealing ring 66 at the threaded joint 64. When the quartz lamp tube 62 is connected to the threaded joint 64, the sealing ring 66 is pressed. The sealing ring 66 can improve the sealing line between the lamp holder 61 and the quartz lamp tube 62 and prevent water leakage.

[0021] The biological packing material includes multiple rope-type biological packing materials 7, which are suspended in the biological packing tank 2 by crossbars 11. The use of rope-type biological packing materials 7 and their suspension by crossbars 11 increases the biofilm attachment area, optimizes hydraulic conditions and gas-liquid mass transfer efficiency, and is conducive to the growth and metabolism of microorganisms, thereby improving the biodegradation capacity of organic pollutants in wastewater.

[0022] The aeration mechanism includes a blower, an air pipe 12, and multiple aeration heads 13. The multiple aeration heads 13 are connected to the air pipe 12, which is arranged at the bottom of the biological packing tank 2. The blower is connected to the air pipe 12. When the blower is working, the aeration heads 13 discharge air to compensate for oxygen in the water, which is beneficial to the reproduction of aerobic organisms.
