Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a pre-disinfection system for use in medical infectious disease departments. Background Technology

[0002] Currently, wastewater from infectious disease departments contains high concentrations of pathogenic microorganisms, chemical residues, and biotoxic substances. Traditional treatment processes typically involve direct discharge into septic tanks or sewage treatment plants after a single disinfection step. However, the lack of a pre-disinfection stage allows pathogens to easily spread within the sewage system, posing a risk of nosocomial infections. Furthermore, excessive use of chlorine-containing disinfectants leads to excessive residual chlorine levels, which, when directly discharged into the municipal sewer system, inhibits the effectiveness of subsequent biological treatment. In addition, the dispersed layout of treatment units results in insufficient contact time between disinfectants and wastewater, and the absence of dedicated waste gas treatment devices allows volatile harmful substances such as chlorine and organic amines to easily cause secondary pollution. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a pre-disinfection system for medical infectious disease departments to solve the above problems.

[0004] The present invention adopts the following solution:

The collection tank is used to receive medical wastewater discharged from the medical infectious disease department and further transfer it to the pre-disinfection tank. One input end of the pre-disinfection tank is connected to the disinfectant device for co-treatment of the medical wastewater. One input end of the dechlorination tank is connected to the reducing agent device for co-treatment of the pre-treated medical wastewater discharged from the pre-disinfection tank.

[0013] As a further improvement, the collection tank is connected to a septic tank to discharge untreated wastewater; and the septic tank is connected to a sewage treatment plant.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] The pre-disinfection system of this application provides a complete multi-stage, coordinated treatment process for medical wastewater discharged from the infectious disease department.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example

[0022] Combination Figures 1 to 3This embodiment provides a pre-disinfection system for a medical infectious disease department, including a collection tank 100, a pre-disinfection tank 200, a dechlorination tank 300, a septic tank 400, a sewage treatment plant 500, a disinfectant device 600, a reducing agent device 700, and a waste gas adsorption device 800. The collection tank 100 receives medical wastewater discharged from the medical infectious disease department and further transfers it to the pre-disinfection tank 200. One input end of the pre-disinfection tank 200 is connected to the disinfectant device 600 for co-treatment of the medical wastewater. One input end of the dechlorination tank 300 is connected to the reducing agent device 700 for co-treatment of the pre-treated medical wastewater discharged from the pre-disinfection tank 200. One output end of the pre-disinfection tank 200 is connected to the other input end of the dechlorination tank 300 via a pipeline. The septic tank 400 is connected to another output end of the pre-disinfection tank 200, and the sewage treatment plant 500 is connected to one output end of the dechlorination tank 300; the waste gas adsorption device 800 is used to receive and treat the waste gas generated by the collection tank 100, the pre-disinfection tank 200, and the dechlorination tank 300.

[0023] The aforementioned pre-disinfection system provides a complete multi-stage, collaborative treatment process for medical wastewater discharged from the infectious disease department. It first receives the medical wastewater from the infectious disease department and transports it to the pre-disinfection tank 200. The pre-disinfection tank 200 serves as the first treatment stage, with one end connected to the disinfectant device 600 to perform preliminary disinfection treatment on the wastewater, reducing the number of pathogens at the source. The pre-disinfected wastewater is then piped from the pre-disinfection tank 200 to the dechlorination tank 300, which is connected to the reducing agent device 700 at one end, collaboratively completing dechlorination and further purification work to ensure that harmful residues in the wastewater are effectively removed. Furthermore, the pipeline connection between the pre-disinfection tank 200 and the dechlorination tank 300 achieves a seamless transition from primary to advanced wastewater treatment.

[0024] One output of the pre-disinfection tank 200 is connected to the septic tank 400, while the output of the dechlorination tank 300 is connected to the sewage treatment plant 500. This diversion arrangement helps to further refine and classify the treatment of various types of wastewater according to the requirements of different treatment stages. In particular, the waste gas adsorption device 800 is used to capture and treat the waste gas generated by the collection tank 100, the pre-disinfection tank 200 and the dechlorination tank 300 during the treatment process, so as to avoid the spread of pollutants, ensure environmental safety, realize efficient pre-disinfection, dechlorination and subsequent treatment of medical wastewater, and effectively adsorb the waste gas generated during the treatment process, thereby reducing the risk of environmental pollution and the risk of pathogen spread.

[0025] In this embodiment, the waste gas adsorption device 800 includes a waste gas treatment box, which is equipped with at least an ultraviolet (UV) lamp assembly and an activated carbon assembly. Specifically, the UV lamp assembly is configured as multiple UV lamps 802 disposed within the box. The activated carbon assembly is configured as coconut shell activated carbon 803 disposed within the box. Through the synergistic operation of UV light and activated carbon, the waste gas adsorption device 800 not only achieves sterilization and decomposition of the waste gas, but also effectively adsorbs and removes residual pollutants, ensuring that the treated waste gas meets higher environmental standards.

[0026] In this embodiment, the exhaust gas treatment box uses an induced draft fan 804 to rapidly draw the exhaust gas generated from the collection tank 100, pre-disinfection tank 200, and dechlorination tank 300 into its air inlet 801. An exhaust pipe 805 is connected to the outside of the box. The induced draft fan 804 rapidly draws the exhaust gas generated in each unit tank into the exhaust gas treatment box, ensuring that the exhaust gas can promptly enter the ultraviolet and activated carbon components for treatment, preventing the exhaust gas from stagnating in the system and thus reducing potential pollution risks. Furthermore, through the exhaust pipe 805, the treated exhaust gas can be smoothly discharged through the exhaust pipe 805 after the combined action of the internal ultraviolet light and activated carbon, achieving continuous airflow circulation and ensuring the overall efficient operation of the exhaust gas treatment system.

[0027] Therefore, the odor is collected by the exhaust fan and sterilized and adsorbed by ultraviolet light, activated carbon and other methods, which avoids the spread of bacteria and toxic and harmful gases in the pre-disinfection tank 200. The operation is simple, saves manpower, reduces workload and prevents the spread of infectious diseases in sewage.

[0028] like Figure 3 As shown, in this embodiment, the pre-disinfection tank 200 includes a disinfection box, and the disinfectant device 600 is used to add disinfectant solution to the disinfection box. Specifically, the disinfection box includes a sludge discharge opening 201, a corrugated baffle 202, a corrugated baffle outer frame 203, a water inlet 204, a dosing port 205, a waste gas collection port 206, and a chlorine detector 207. The water inlet 204 and the dosing port 205 respectively form the input ends of the pre-disinfection tank 200, and the sludge discharge opening 201 forms the output end of the pre-disinfection tank 200. Clearly, the corrugated baffle 202 and the corrugated baffle outer frame 203 are formed on the upper and lower sides of the disinfection box, respectively, to extend the transmission path of wastewater within the disinfection box.

[0029] Correspondingly, the dechlorination tank 300 includes a dechlorination chamber, which is arranged adjacent to the disinfection chamber. The dechlorination chamber includes an inlet tee pipe 301, an outlet 302, and a static mixer 303. One end of the inlet tee pipe 301 is connected to the output end of the pre-disinfection tank 200, and the other end is connected to the reducing agent device 700 to form one input end of the dechlorination tank 300, while the other end forms the other input end of the dechlorination tank 300.

[0030] In the above process, the addition of disinfectant is controlled by chlorine detector 207. After disinfection, the disinfectant is discharged into dechlorination tank 300. A static mixer 303 is added at the front end of the dechlorination tank 300. A reducing agent is added at the static mixer 303 to enhance the mixing effect. Dechlorination is carried out in dechlorination tank 300. After dechlorination, the disinfectant is discharged into sewage station 500, thus not affecting the biochemical operation of hospital terminal sewage station 500.

[0031] In this embodiment, the disinfectant device 600 is connected to the pre-disinfection tank 200 via an injection pipeline for supplying disinfectant. The reducing agent device 700 is connected to the dechlorination tank 300 via another injection pipeline for supplying reducing agent. Obviously, the injection pipeline is existing water supply technology, and therefore will not be described in detail here.

[0032] In this embodiment, the collection tank 100 is connected to the septic tank 400 to discharge untreated wastewater. The septic tank 400 is also connected to the sewage treatment plant 500. On one hand, untreated wastewater can be directly discharged into the septic tank 400 and the sewage treatment plant 500, thus achieving rapid wastewater discharge. On the other hand, wastewater requiring pretreatment undergoes a series of filtration, disinfection, and dechlorination treatments in the collection tank 100, pre-disinfection tank 200, and dechlorination tank 300 before being discharged into the septic tank 400 and the sewage treatment plant 500, thereby achieving pre-disinfection treatment of medical wastewater.

[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
