Description

Technical Field

[0001] This utility model relates to the field of sterilization and disinfection technology for municipal solid waste and sewage, specifically a sterilization and disinfection device for treating municipal solid waste incineration slag and sewage. Background Technology

[0002] Domestic wastewater sterilization and disinfection refers to the process of sterilizing and disinfecting wastewater generated from domestic waste to kill pathogenic microorganisms in the water, reduce the risk of disease transmission, and ensure that the effluent meets safe discharge or reuse standards. It typically involves a comprehensive treatment using physical, chemical, or biological methods (such as flocculation, filtration, disinfectant dosing, physical sterilization such as ultraviolet / ozone, and disinfection after biological treatment) to ensure that pollutant concentrations meet relevant regulatory requirements and protect the environment and public health.

[0003] However, existing microbial exposure time is insufficient and sterilization efficiency is low, leading to an increased risk of pathogen residue in the effluent. As a result, the sterilization of sewage is not thorough enough and cannot fully disinfect the sewage, polluting the environment and public health. In order to address the above problems, the inventors propose a sterilization and disinfection device for treating sewage from municipal solid waste incineration slag to solve the above problems. Utility Model Content

[0004] In order to solve the problem of insufficient sterilization and inability to fully disinfect sewage, the purpose of this utility model is to provide a sterilization and disinfection device for treating sewage from municipal solid waste incineration slag.

[0018] 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.

[0019] like Figure 1-4 As shown, this utility model provides a sterilization and disinfection device for treating wastewater from municipal solid waste incineration slag. It includes a primary housing 1, with a secondary housing 11 fixedly connected to the outside of the primary housing 1. An aeration assembly 13 is installed inside the secondary housing 11. The aeration assembly 13 is used to ensure sufficient contact between ozone and wastewater. Ozone has strong oxidizing properties, can rapidly decompose organic matter, reduce color and turbidity, decompose recalcitrant pollutants, and has a significant killing effect on pathogenic microorganisms. The inner wall of the primary housing 1 is provided with staggered guide plates 22, which have a small inclination angle to facilitate wastewater flow and transport. A germicidal lamp 23 is installed inside the primary housing 1. The product model of the germicidal lamp 23 is ZW150D15Y-UA1000 ultraviolet germicidal lamp 23, which can kill bacteria in the wastewater. The system eliminates wastewater. A channel 2 connects the No. 1 tank 1 and the No. 2 tank 11. The channel 2 is used to transfer wastewater from the No. 2 tank 11 to the No. 1 tank 1. A baffle 21 is movably inserted inside the No. 1 tank 1. The baffle 21 is located on the side of the channel 2 and is used to open and close the channel 2. The flow rate of the wastewater can be controlled by the size of the opening. A fixing plate 24 is fixedly installed on the outside of the No. 2 tank 11. The fixing plate 24 is used for fixed support. An electric cylinder 25 is fixedly installed inside the fixing plate 24. The output end of the electric cylinder 25 is inserted through the fixing plate 24 and fixedly connected to the baffle 21. The output end of the electric cylinder 25 drives the baffle 21 to move up and down. Several sterilizing lamps 23 are located above the guide plate 22. The sterilizing lamps 23 can sterilize the wastewater flowing on the guide plate 22.

[0020] A pretreatment box 12 is fixedly installed at the top of the second box 11. The pretreatment box 12 is detachably installed on top of the second box 11. A filter box 3 is movably inserted inside the pretreatment box 12. A first filter plate 31 is fixedly installed on the bottom wall of the filter box 3. A support frame 33 is fixedly installed on the periphery of the filter box 3. A second filter plate 32 is installed on top of the support frame 33. Through double filtration, the filtration effect and efficiency can be improved, and clogging can be avoided. A handle 34 is fixedly installed at the top of the second filter plate 32. The second filter plate 32 can be disassembled for easy cleaning of the filtered impurities. A handle 35 is fixedly installed on the outside of the filter box 3. The aperture of the second filter plate 32 is larger than that of the first filter plate 32.

[0021] By adopting the above technical solutions, wastewater can be pretreated and impurities can be filtered out, thus avoiding problems such as equipment blockage.

[0022] A liquid outlet pipe 14 is installed on the outside of box 1, and a liquid inlet pipe 15 is installed on the outside of box 2.

[0023] By adopting the above technical solution, the outlet pipe 14 is used to discharge the sterilized wastewater, and the inlet pipe 15 can transmit the wastewater to be sterilized and disinfected to the pretreatment tank 12.

[0024] Flanges 16 are fixedly installed on the outside of both the liquid outlet pipe 14 and the liquid inlet pipe 15.

[0025] By adopting the above technical solution, flange 16 facilitates the connection of inlet pipe 15 and outlet pipe 14 to external sewage equipment pipelines.

[0026] The inner wall of box 11 is fixed with symmetrically distributed guide plates 36.

[0027] By adopting the above technical solution, a cover plate 37 is provided at the top of the second box 11 with a rotating hinge.

[0028] By adopting the above technical solution, the pretreatment box 12 can be opened and closed through the cover plate 37.

[0029] The top of the No. 1 box is equipped with a detachable inspection plate 17.

[0030] By adopting the above technical solution, the inspection plate 17 facilitates the inspection and maintenance of the No. 1 box 1.

[0031] An auxiliary rod 26 is fixedly provided at the top of the baffle 21, and the auxiliary rod 26 is movably inserted into the fixed plate 24.

[0032] By adopting the above technical solution, the auxiliary rod 26 is used to assist the baffle 21 in moving up and down.

[0033] Working principle: First, connect the sewage source to the second tank 11. The sewage will first pass through the second filter plate 32 and the first filter plate 31 for secondary filtration, filtering out suspended solids and impurities to prevent equipment blockage. Then, within the second tank 11, ozone is mixed with the sewage through the aeration component 13. Ozone has strong oxidizing properties, rapidly decomposing organic matter, reducing color and turbidity, decomposing recalcitrant pollutants, and significantly killing pathogenic microorganisms. Subsequently, the electric cylinder 25 is activated. When the electric cylinder 25 starts working, the output shaft end of the electric cylinder 25 drives the baffle 21 to move upward with the assistance of the auxiliary rod 26, thus opening the channel 2. This allows the sewage to enter the guide plate 22 inside the first box 1 through the channel 2. The sewage will pass through multiple guide plates 22 in sequence. At the same time, the germicidal lamp 23 sterilizes the flowing sewage, making the sewage flow slowly and increasing the exposure time and area of ​​the water body. This allows the microorganisms to be more fully exposed to the ultraviolet or photo-oxidation sterilization area of ​​the germicidal lamp 23, thereby achieving a higher sterilization rate per unit volume.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
