Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an environmental protection pool structure for deodorizing and sterilizing sewage treatment. Background Technique

[0002] At present, the treatment process of domestic sewage mainly includes stirring treatment, filtering out waste residues and squeezing out the water in the waste residues, and fine filtering treatment. In the initial stirring treatment, large waste residues in the sewage can be broken up to facilitate the suction and transmission of the sewage by the suction pipe to the next pressing treatment and prevent the suction pipe from being blocked. However, in the existing stirring treatment equipment, most only have one pool body and a stirrer, and no sterilization and deodorization device is set, making the whole pool body and the surrounding environment extremely stinky. This is because domestic sewage contains a large number of bacteria and microorganisms, which are prone to react with substances in the sewage, thus generating malodorous gases, affecting the environment and people's physical and mental health, especially the impact on the staff in the sewage treatment plant. In severe cases, people can even be fainted by the stench.

[0003] To solve this technical problem, the following several solutions have emerged: First, an exhaust fan is set for ventilation. Although it can reduce the concentration of malodorous gases, it only discharges the stench to other places and does not solve the problem at the root. It is still very stinky in the subsequent pressing and fine filtering treatments. Second, various sewage treatment chemical agents are added to the sewage pool. Although it can play a role in sterilization and deodorization, it is also easy to produce other harmful by-products, and a device for removing these harmful by-products needs to be set, resulting in a complex structure, which not only affects the sewage treatment efficiency, but also has a certain impact on the environment and human health. Third, as disclosed in a Chinese patent document with a patent application number of 202022747725.0 and a title of "An Ultrasonic Wastewater Treatment Equipment without Chemical Agents", the technical solution mainly includes an outer pool body, a stirring rod, an ultrasonic generator, and an ultraviolet disinfection lamp. Among them, the outer pool body is provided with a sewage accommodation cavity, the stirring rod is arranged in the sewage accommodation cavity, the ultrasonic generator is arranged on the outer side wall of the outer pool body, and the ultraviolet disinfection lamp is arranged above the outer pool body. When in use, the ultrasonic technology and ultraviolet light technology can be used to degrade the organic pollutants in the sewage to achieve the purpose of sterilization and deodorization. However, this solution still has the following deficiencies: First, since the ultrasonic generator is arranged on the outer side wall of the outer pool body, this solution can only be applied to small pool bodies and is difficult to be applied to large pool bodies and pool pits dug on the ground. The type of the pool body is restricted, and there is a problem that it is difficult to vibrate all types of pool bodies. Second, the ultraviolet disinfection lamp is arranged above the outer pool body. When irradiating, most of the ultraviolet light will be refracted away in the opposite direction of the water surface, resulting in poor ultraviolet light sterilization effect. Third, the ultrasonic generator and the ultraviolet disinfection lamp are not integrated together, making the later maintenance and repair inconvenient. Therefore, it is very necessary to redesign an environmental protection pool structure for deodorizing and sterilizing sewage treatment. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the above problems and deficiencies, and provide an environmental protection pool structure for sewage treatment, deodorization and sterilization.

It can be applied to various types and sizes of pool bodies, and is not easy to obstruct the stirring device. Ultraviolet light can also directly irradiate the interior of the sewage, preventing most of the ultraviolet light from being refracted in the reverse direction. It can also directly output ozone into the sewage to kill bacteria, viruses and other microorganisms in the sewage, and is not easy to generate malodorous gases, so as to further improve the effect of sterilization and deodorization, achieve the purpose of solving the odor problem from the root, and does not require the use of chemical agents, does not produce harmful substances, and is very environmentally friendly. In addition, through integrated design, later maintenance and repair can be carried out together, which is very convenient.

[0005] The technical solution of the present utility model is realized as follows: An environmental protection pool structure for sewage treatment, deodorization and sterilization, includes a pool body with a sewage accommodation cavity and a stirring device arranged in the sewage accommodation cavity. The feature is that it further includes at least one deodorization and sterilization module, and the deodorization and sterilization module is arranged on the cavity wall of the sewage accommodation cavity; an ultrasonic vibration device, an ultraviolet light sterilization device, and an ozone output sterilization device are integrated in the deodorization and sterilization module.

[0015] The beneficial effects of the utility model: By arranging a deodorizing and sterilizing module on the cavity wall of the sewage accommodating cavity, and integrating an ultrasonic vibration device, an ultraviolet light sterilization device and an ozone output sterilization device in the deodorizing and sterilizing module. In this way, not only can the sewage be directly subjected to ultrasonic vibration, the effect is more direct and effective, and it can be applied to various types and sizes of pool bodies, but also it is not easy to obstruct the stirring device. At the same time, the ultraviolet light emitted by the ultraviolet light sterilization device can also directly irradiate the inside of the sewage to prevent most of the ultraviolet light from being refracted in the reverse direction, so as to ensure a very good ultraviolet light sterilization effect. Similarly, by arranging an ozone output sterilization device in the deodorizing and sterilizing module, ozone can be directly output into the sewage to kill bacteria, viruses and other microorganisms in the sewage, so that it is not easy to react with substances in the sewage, and thus it is not easy to generate malodorous gases, so as to further improve the sterilization and deodorization effect.

[0023] As Figure 1 shown in Figure 4 a sewage treatment deodorizing and sterilizing environmental protection pool structure according to the present utility model includes a pool body 1 with a sewage accommodating cavity 11 and a stirring device 2 arranged in the sewage accommodating cavity 11. To achieve the purpose proposed by the present utility model, the present utility model further includes at least one deodorizing and sterilizing module 3, and the deodorizing and sterilizing module 3 is arranged on the cavity wall of the sewage accommodating cavity 11; an ultrasonic vibration device 4, an ultraviolet light sterilizing device 5, and an ozone output sterilizing device 6 are integrated in the deodorizing and sterilizing module 3. The present utility model can directly perform ultrasonic vibration on sewage, with a more direct and effective effect, can be applicable to various types and sizes of pool bodies, and is not easy to obstruct the stirring device. The ultraviolet light can also directly irradiate the inside of the sewage, preventing most of the ultraviolet light from being refracted in the reverse direction, and can directly output ozone into the sewage to kill bacteria, viruses, and other microorganisms in the sewage, and is not easy to generate malodorous gases, so as to further improve the sterilization and deodorization effect and achieve the purpose of solving the odor problem from the root cause. In addition, by integrating the ultrasonic vibration device 4, the ultraviolet light sterilizing device 5, and the ozone output sterilizing device 6 together, the later maintenance and repair can be carried out together, which is very convenient.

[0024] Specifically, the ultrasonic vibration device 4 can play a role in ultrasonic vibration on the sewage in the sewage holding cavity 11, so that the waste residue adhered to the wall of the sewage holding cavity 11 is shaken off by ultrasonic vibration, so that the shaken-off waste residue is re-involved in the vortex formed by the stirring device 2 and then sucked and transported by the suction pipe to the next pressing treatment, so that the waste residue in the sewage is not easily adhered to and accumulated on the wall of the sewage holding cavity 11. At the same time, the ultrasonic vibration can also play a role in loosening the large waste residue in the sewage, so that the stirring device 2 can quickly break up the large waste residue. The ultraviolet light emitted by the ultraviolet light sterilization device 5 can irradiate the microorganisms in the sewage, directly destroy their cell structure and DNA, and make them die, so as to achieve a high-efficiency disinfection effect. The ozone output sterilization device 6 can directly output ozone into the sewage to kill bacteria, viruses and other microorganisms in the sewage, so it is not easy to react with the substances in the sewage, and thus it is not easy to generate malodorous gases, so as to further improve the purpose of sterilization and deodorization. Through the above structural design, the purpose of solving the odor problem from the root can be achieved.

[0025] In the actual application process, the number of the deodorization and sterilization modules 3 is several, and the actual application number can be appropriately increased or decreased according to the size of the sewage holding cavity 11. Preferably, as Figure 1 shown, the number of the deodorization and sterilization modules 3 is eight, and four of the deodorization and sterilization modules 3 are respectively arranged at the four corners of the sewage holding cavity 11, and one deodorization and sterilization module 3 is respectively arranged on the four walls of the sewage holding cavity 11. In this way, it does not affect the stirring work of the stirring device 2, and can make the environmental protection pool structure obtain a very good deodorization and sterilization effect.

[0026] In order to enable the deodorization and sterilization module 3 to play a reliable role in deodorizing and sterilizing the sewage in the sewage holding cavity 11, as Figure 1 shown, the deodorization and sterilization module 3 has a vertical strip structure, and the upper end and the lower end of the deodorization and sterilization module 3 respectively extend to the upper end and the lower end of the sewage holding cavity 11. Through such a structural design, no matter how deep the sewage in the sewage holding cavity 11 is, it can play a very reliable and effective role in deodorizing and sterilizing the sewage.

[0027] In order to further improve the structure of the deodorization and sterilization module 3, make the structure scientific, reasonable, simple and easy to manufacture, as Figure 3 、 Figure 4 and Figure 5As shown, the deodorizing and sterilizing module 3 includes a housing 31, a housing cover 32, and a transparent lamp cover 33. The housing 31 is provided with an inner cavity 34 that penetrates from its upper end to the lower end. A sealing end portion 35 is provided at the lower end of the inner cavity 34. The ultrasonic vibration device 4 and the ozone output sterilizing device 6 are respectively arranged in the inner cavity 34. The housing cover 32 is placed on the upper end of the inner cavity 34. An ultraviolet lamp accommodating cavity 36 is further provided on the front surface of the housing 31. The ultraviolet light sterilizing device 5 is arranged in the ultraviolet lamp accommodating cavity 36. The transparent lamp cover 33 is placed on the ultraviolet lamp accommodating cavity 36. During use, the ultrasonic vibration device 4 vibrates the housing 31, and then conducts it to the sewage through the housing 31. In the actual application process, a sealing and waterproof rubber pad is further provided between the transparent lamp cover 33 and the ultraviolet lamp accommodating cavity 36 to play a role in sealing and waterproofing. Through the setting of the sealing end portion 35, it can be ensured that the inner cavity 34 will not be filled with sewage, and the service life of each electrical component in the inner cavity 34 can be guaranteed.

[0028] In order to enable the housing 31 to be installed at various positions of the sewage accommodating cavity 11 according to the shape of the sewage accommodating cavity 11, such as Figure 5 and Figure 6 As shown, the radial cross-section of the housing 31 is in a rectangular structure, a triangular structure, or a semi-circular structure. When the radial cross-section shape of the sewage accommodating cavity 11 is square, the housing 31 adopts a triangular structure, which can make the shape of the deodorizing and sterilizing module 3 match the shape of the corners of the sewage accommodating cavity 11, so that the deodorizing and sterilizing module 3 can be more stably installed on the corners of the sewage accommodating cavity 11. When the housing 31 adopts a rectangular structure or a semi-circular structure, the deodorizing and sterilizing module 3 can be stably installed on the side wall of the sewage accommodating cavity 11. Of course, when the radial cross-section shape of the sewage accommodating cavity 11 is circular, the back of the housing 31 can be correspondingly made into a circular arc structure, so that the deodorizing and sterilizing module 3 can be stably installed on the side wall of the sewage accommodating cavity 11.

[0029] In order to enable the stirred water flow to smoothly slide over the deodorizing and sterilizing module 3 without easily blocking the water flow, such as Figure 5 and Figure 6 As shown, arc-shaped transition water guiding structures 30 are respectively provided on the left and right sides of the housing 31.

[0030] In order to further improve the structure of the housing 31, make its structure scientific, reasonable, simple, and easy to manufacture, such as Figure 5As shown, the housing 31 includes a front cover shell 311, a back plate 312, and a fixing screw 313. The back plate 312 is fixed to the back of the front cover shell 311 by the fixing screw 313, and a sealing rubber pad 314 is also provided between the back plate 312 and the front cover shell 311. The inner cavity 34 is formed by the front cover shell 311 and the back plate 312, and the ultraviolet lamp accommodating cavity 36 is provided on the front surface of the front cover shell 311. By setting the fixing screw 313, the front cover shell 311 and the back plate 312 can be firmly fixed together, and the installation and later maintenance of the ultrasonic vibration device 4 and the ozone output sterilization device 6 are also convenient. Specifically, in order to make the back of the front cover shell 311 flush with the back of the back plate 312, a step is provided on the front cover shell 311, and the back plate 312 is buckled on the step. By setting the sealing rubber pad 314, a sealing and waterproof effect can be achieved. When the shell 31 adopts a triangular structure, the back plate portion 312 can be a straight plate or a right-angled plate. In order to make the overall structural strength of the front cover shell portion 311 better, the back plate portion 312 adopts a straight plate, and the back plate portion 312 is arranged on one side of the back of the front cover shell portion 311.

[0031] In order to facilitate the deodorization and sterilization module 3 to be firmly installed on the wall of the sewage receiving chamber 11, as shown in FIG. Figure 3 As shown, the utility model further includes a locking screw 37 . The left and right sides of the housing 31 are respectively provided with fixing lugs 38 . One end of the locking screw 37 passes through the fixing lugs 38 and is locked on the wall of the sewage containing chamber 11 .

[0032] In order to make the output ozone be evenly mixed with the sewage to ensure the best deodorization and sterilization effect, such as Figure 2 , Figure 4 and Figure 5 As shown, the front surface of the shell 31 is provided with a through hole 315 penetrating to the inner cavity 34, and the ozone output sterilization device 6 includes an ozone generator 61 and a delivery pipe 62. The ozone generator 61 is arranged in the inner cavity 34 or outside the inner cavity 34, and the output end of the ozone generator 61 is connected with the through hole 315 through the delivery pipe 62; the through hole 315 is located at the bottom of the shell 31. Specifically, the through hole 315 is arranged on the front cover part 311. By arranging the through hole 315 at the bottom of the shell 31, ozone gas can be injected into the bottom of the sewage receiving chamber 11, and then the stirring device 2 is used to stir the ozone gas and the sewage to be fully mixed, and then as the ozone gas moves upward, the sewage in various places in the sewage receiving chamber 11 can be deodorized and sterilized.

[0033] To prevent sewage backflow, Figure 5 As shown, the delivery pipe 62 is also provided with a one-way valve 63 .

[0034] In order to further improve the structure of the stirring device 2 and enable the stirring device 2 to be stably installed in the sewage holding cavity 11, as Figure 1 and Figure 2 shown, the utility model further includes an installation bracket 7 erected on the pool body 1. The stirring device 2 includes a stirring paddle 21, a connecting rod 22, and a motor 23. The motor 23 is arranged on the installation bracket 7, and the stirring paddle 21 is arranged in the sewage holding cavity 11, and the stirring paddle 21 is drivingly connected to the motor 23 through the connecting rod 22.

[0035] In the actual application process, the pool body 1 can be a pool body structure formed by splicing multiple steel plates, or a pool body structure formed by digging a pit on the ground.

[0036] In the actual application process, the ultrasonic vibration device 4 is an ultrasonic transducer, and the ultraviolet light sterilization device 5 is an ultraviolet lamp. The ultrasonic transducer is a common ultrasonic vibration product on the market. Both the ultraviolet lamp and the ozone generator 61 are common sterilization and disinfection products on the market, and can be easily purchased on the market. Their specific structures will not be elaborated here too much.

[0037] As Figure 7 shown, the sewage stirred in the pool body 1 is sucked and transmitted to the next pressing device 200 through the suction pipe 100 for waste residue pressing treatment.
