[0002] Medical wastewater mainly originates from wastewater discharged from hospital treatment rooms, laboratories, wards, laundry rooms, X-ray rooms, and operating rooms. Its sources and composition are highly complex. Hospital wastewater contains large amounts of pathogenic bacteria, viruses, and chemical agents, exhibiting characteristics of spatial pollution, acute infectiousness, and latent infectiousness. The treatment process of medical wastewater generates significant amounts of odorous gases, primarily from volatile organic acids or hydrogen sulfide produced by the hydrolysis acidification process and odorous organic matter carried out by the aeration airflow during the contact oxidation process.

[0003] Existing medical wastewater treatment processes involve steps such as sedimentation and aeration, which present the following problems in practice:

[0004] 1. Because the odor in wastewater contains a large number of pathogens, chemical agents, radioactive substances and other substances, traditional wastewater odor treatment methods cannot completely remove it.

[0005] 2. During the initial wastewater treatment process, a large amount of odor accumulates on the top of the wastewater treatment tank, causing a large amount of pathogens in the odor to accumulate in the treatment equipment. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a medical wastewater odor recovery device to solve the current technical problem that medical odor containing pathogens accumulates in wastewater treatment equipment, and that the odor in medical wastewater contains a large number of pathogens and other medical substances, and that traditional odor treatment cannot disinfect it.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] An odor recovery device for medical wastewater includes a wastewater treatment tank, the top of which is connected to an odor treatment mechanism via a vent pipe.

[0010] The odor treatment mechanism includes an aeration assembly, which includes an aeration box. An aeration pipe is fixedly installed on the inner surface of the aeration box. The top end of the aeration pipe passes through the aeration box and extends to the outside of the aeration box. The top end of the aeration pipe is connected to the bottom end of a ventilation pipe. The aeration assembly also includes a second aeration pipe, the right side of which passes through the aeration box and extends into the interior of the aeration box.

[0011] As an improved technical solution, the odor treatment mechanism further includes a gas treatment mechanism, which includes a gas purification box. The inner cavity of the gas purification box is connected to a fan. The bottom of the fan is connected to an air inlet pipe. The top of the air inlet pipe is connected to a gas plasma tube. An ion generator is fixedly installed on the inner wall of the gas plasma tube. The top of the gas plasma tube is connected to an air outlet pipe.

[0012] As an improved technical solution, the gas treatment mechanism further includes an odor purification pipe, the outer surface of which is connected to the top of the gas outlet pipe, and a valve is fixedly installed on the outer surface of the odor purification pipe.

[0013] As an improved technical solution, the gas treatment mechanism further includes an ultraviolet lamp, the outer surface of which is fixedly connected to the inner wall of the odor purification tube.

[0014] As an improved technical solution, the odor treatment mechanism further includes a deodorization component, which includes an adsorption box.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model incorporates a design to treat odors generated during medical wastewater treatment. By using an aeration box and connecting pipe in conjunction with a wastewater treatment tank and a primary aeration pipe, and by using primary and secondary aeration pipes in conjunction with the aeration box and odor purification pipe, particulate matter in the odor is removed. Simultaneously, by using an ion generator and gas plasma pipe in conjunction with an outlet and inlet pipe, air is converted into positive and negative oxygen ions, which react with the odor, causing a change in the chemical structure of the odor molecules, ultimately generating stable and harmless small molecules such as carbon dioxide and water. Finally, by using the odor purification pipe and ultraviolet lamp in conjunction with an adsorption rack and adsorbent, bacteria and odor molecules in the odor are eliminated.

[0018] 2.

[0032] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a medical wastewater odor recovery device, which includes a wastewater treatment tank 1, and the top of the wastewater treatment tank 1 is connected to an odor treatment mechanism 2 through a vent pipe 3.

[0033] The odor treatment device 2 includes an aeration assembly 21, which includes an aeration box 211. An aeration pipe 212 is fixedly installed on the inner surface of the aeration box 211. The top end of the aeration pipe 212 passes through the aeration box 211 and extends to the outside of the aeration box 211. The top end of the aeration pipe 212 is connected to the bottom end of the ventilation pipe 3. The aeration assembly 21 also includes a second aeration pipe 213. The right side of the second aeration pipe 213 passes through the aeration box 211 and extends into the interior of the aeration box 211.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the odor treatment unit 2 also includes a gas treatment unit 22, which includes a gas purification box 221. The inner cavity of the gas purification box 221 is connected to a fan 222. The bottom of the fan 222 is connected to an air inlet pipe 223. The top of the air inlet pipe 223 is connected to a gas plasma pipe 224. An ion generator 225 is fixedly installed on the inner wall of the gas plasma pipe 224. The top of the gas plasma pipe 224 is connected to an air outlet pipe 226.

[0035] A large number of positive and negative oxygen ions are generated by an ion generator under the action of a high-voltage electric field. These ions have strong oxidizing properties and can oxidize and decompose odor molecules in a very short time, converting them into harmless small molecules such as carbon dioxide and water.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the gas treatment mechanism 22 also includes an odor purification pipe 227, the outer surface of which is connected to the top end of the gas outlet pipe 226, and a valve 228 is fixedly installed on the outer surface of the odor purification pipe 227.

[0037] like Figure 1 and Figure 5 As shown, the gas treatment mechanism 22 also includes an ultraviolet lamp 229, the outer surface of which is fixedly connected to the inner wall of the odor purification tube 227.

[0038] This method utilizes high-energy UV light beams to decompose oxygen molecules in the air, generating free oxygen (active oxygen). Ozone then synergistically photodegrades and oxidizes organic waste gases and odorous gases, transforming them into low-molecular-weight compounds, CO2, and H2O. This approach offers high treatment efficiency, strong adaptability, low operating costs, and stable equipment performance.

[0039] like Figures 1 to 6 As shown, the odor treatment mechanism 2 also includes a deodorization component 23, which includes an adsorption box 231. An adsorption rack 232 is fixedly installed in the inner cavity of the adsorption box 231. An adsorbent 233 is fixedly installed on the inner surface of the adsorption rack 232. A clip 234 is fixedly installed on the back of the adsorption rack 232. A bolt 235 is threadedly installed on the inner surface of the adsorption rack 232. The outer surface of the bolt 235 is threadedly connected to the inner surface of the adsorption box 231. An exhaust pipe 236 is connected to the front of the adsorption box 231.

[0040] Adsorbent 233 is typically activated carbon, a porous material with a large specific surface area and a fine porous surface structure. This allows it to adsorb metal ions, harmful gases, organic pollutants, pigments, etc., from wastewater and exhaust gases. Specifically, when adsorbing substances in odorous gases, activated carbon mainly relies on its physical adsorption properties, adsorbing organic matter and odorous substances in the odorous gases through its microporous structure.

[0041] like Figure 1 and Figure 6 As shown, a second valve 237 is fixedly installed on the outer surface of the exhaust pipe 236. The top of the second valve 237 is connected to a connecting pipe 238, and the bottom end of the connecting pipe 238 is connected to the top of the wastewater treatment tank 1.

[0042] During operation, medical wastewater first enters wastewater treatment tank 1 for treatment. The odor generated during treatment enters aeration pipe 212 through vent pipe 3, then is sprayed out and reacts fully with the liquid in aeration box 211. The gas, after initial aeration, enters aeration pipe 213 and reacts with the liquid at its outlet, trapping residual particulate matter in the odor. The aerated gas then enters odor purification pipe 227. Simultaneously, fan 222 draws outside air into inlet pipe 223, which then enters gas plasma pipe 224, where the air comes into contact with the high-voltage electricity released by ion generator 225, causing the air to... A large number of positive and negative oxygen ions are generated. These positive and negative oxygen ions first enter the odor purification pipe 227 through the exhaust pipe 226, causing the positive and negative oxygen ions to react repeatedly with the odor. The positive and negative oxygen ions collide with the odor molecules, causing the chemical structure of the odor molecules to change, and finally generating stable and harmless small molecules such as carbon dioxide and water. The odor is decomposed into harmless substances. At the same time, the ultraviolet lamp 229 in the odor purification pipe 227 has a disinfecting effect on the viruses in the odor. Then the odor passes through the first valve 228 and enters the adsorption box 231, where the adsorbent 23 in the adsorption box 231 further adsorbs the residual organic matter and odor substances in the odor, and then it is discharged from the exhaust pipe 236.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
