[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a reverse osmosis sewage filtration and purification device, including a frame 1, a universal wheel 2 is fixedly connected to the bottom of the frame 1, a support plate 3 is fixedly connected to the surface of the frame 1, an operation module 4 is fixedly connected to the surface of the frame 1, a control panel 5 is fixedly connected to the surface of the operation module 4, a pressure gauge 6 is fixedly connected to the surface of the operation module 4, a sewage discharge end 7 is opened on one side surface of the operation module 4, a pure water discharge end 8 is opened on the surface of the operation module 4, a reverse osmosis filtration mechanism 9 is arranged on the inner surface of the frame 1, and a secondary purification mechanism 10 is arranged inside the frame 1;

[0021] The secondary purification mechanism 10 includes a water storage tank 1001, a fourth pipeline 1002, a pure water pump 1003, an ultraviolet disinfection device 1004, a post - activated carbon filter element 1005, and a fifth pipeline 1006. The inner surface of the frame 1 is fixedly connected with the water storage tank 1001. One side surface of the water storage tank 1001 is fixedly connected with the fourth pipeline 1002. One end of the fourth pipeline 1002 is fixedly connected with the pure water pump 1003. The surface of the support plate 3 is fixedly connected with the ultraviolet disinfection device 1004. The surface of the support plate 3 is fixedly connected with the post - activated carbon filter element 1005. The surface of the post - activated carbon filter element 1005 is fixedly connected with the fifth pipeline 1006. Through the setting of the secondary purification mechanism 10, when the raw water is processed by the reverse osmosis filtration mechanism 9, it will be stored in the water storage tank 1001. When water is needed, the pure water pump 1003 is started through the control panel 5. The water in the water storage tank 1001 flows through the fourth pipeline 1002 to the ultraviolet disinfection device 1004 and the post - activated carbon filter element 1005 in sequence under the action of pressure. The ultraviolet disinfection device 1004 uses ultraviolet rays to efficiently kill bacteria, viruses, etc. that may remain in the pure water, ensuring the microbial safety of the pure water. The pure water after ultraviolet disinfection treatment continues to flow to the post - activated carbon filter element 1005 for further deep filtration and secondary adsorption of the pure water, and finally is discharged from the pure water discharge end 8 through the fifth pipeline 1006. At this time, the obtained pure water has extremely high purity and quality, can meet the high - standard pure water application scenarios, adapt to fluctuating water usage requirements, and at the same time ensure the water production quality.

[0022] Furthermore, the pure water pump 1003, the ultraviolet disinfection device 1004, and the post - activated carbon filter element 1005 are all connected by pipelines. The fifth pipeline 1006 is connected to the pure water discharge end 8. Through the setting of the pure water pump 1003, the ultraviolet disinfection device 1004, and the post - activated carbon filter element 1005, during use, the ultraviolet disinfection device 1004 and the post - activated carbon filter element 1005 work together, and the pure water pump 1003 purifies and outputs the water in the water storage tank 1001 twice to ensure the stability of the produced water quality.

[0023] Furthermore, multiple groups of universal wheels 2 are symmetrically arranged at the bottom of the frame 1. The inner surface of the frame 1 is welded with reinforcing ribs. The support plate 3 is fixedly connected to the frame 1 through the reinforcing ribs. Through the setting of the frame 1, the universal wheels 2, and the support plate 3, during use, multiple groups of universal wheels 2 provide convenient mobility for the device, and the reinforcing ribs make the device more stable during the working process.

[0024] Further, the reverse osmosis filtration mechanism 9 includes a raw water pump 901, a water inlet 902, a first pipeline 903, a quartz sand filter 904, an activated carbon filter 905, a fine filter 906, a second pipeline 907, a high-pressure pump 908, a third pipeline 909, a pressure sensor 910, an RO membrane 911, a concentrated water pipe 912, a concentrated water valve 913, a clean water pipe 914, and a clean water valve 915. One side surface of the frame 1 is fixedly connected to the raw water pump 901. One end of the raw water pump 901 is provided with a water inlet 902. One end of the raw water pump 901 is fixedly connected to the first pipeline 903. One end of the first pipeline 903 is fixedly connected to the quartz sand filter 904. The surface of the frame 1 is fixedly connected to the activated carbon filter 905. The surface of the frame 1 is fixedly connected to the fine filter 906. One side of the fine filter 906 is fixedly connected to the second pipeline 907. One end of the second pipeline 907 is fixedly connected to the high-pressure pump 908. One side of the high-pressure pump 908 is fixedly connected to the third pipeline 909. The pressure sensor 910 is arranged on the surface of the third pipeline 909. One end of the third pipeline 909 is fixedly connected to the RO membrane 911. One end of the RO membrane 911 is fixedly connected to the concentrated water pipe 912. The concentrated water valve 913 is fixedly connected to the surface of the concentrated water pipe 912. One end of the RO membrane 911 is fixedly connected to the clean water pipe 914. The clean water valve 915 is fixedly connected to the surface of the clean water pipe 914. Through the setting of the reverse osmosis filtration mechanism 9, when sewage needs to be treated, first, the raw water pump 901 is started through the control panel 5, so that the sewage to be treated enters the quartz sand filter 904 through the water inlet 902 and the first pipeline 903. The quartz sand filter 904 is filled with filtering media such as quartz sand. When the sewage flows through, it can effectively remove larger particulate impurities therein, such as sediment, suspended matter, etc. The preliminarily filtered sewage enters the activated carbon filter 905 through the pipeline. The activated carbon filter 905 adsorbs organic matters, different colors, peculiar smells, etc. in the sewage to further purify the sewage, and then flows into the fine filter 906 to perform high-precision filtration on the sewage to remove residual fine particles and impurities. The water filtered by the fine filter 906 enters the high-pressure pump 908 through the second pipeline 907. The high-pressure pump 908 pressurizes the water to make it reach the pressure required for reverse osmosis, and then transports it to the RO membrane 911 through the third pipeline 909. The RO membrane 911 has a very small pore diameter and only allows water molecules to pass through, while blocking most of the ions, organic matters, and other impurities dissolved in the water. Due to the high pressure, the water is forced to reverse osmosis through the RO membrane 911. Part of the water permeates through the RO membrane 911 to become pure water and enters the water storage tank 1001 through the clean water pipe 914 and the clean water valve 915, and the other part becomes concentrated water and is discharged from the sewage discharge end 7 through the concentrated water pipe 912 and the concentrated water valve 913, thus completing the reverse osmosis filtration of the sewage.

[0025] Further, the quartz sand filter 904, the activated carbon filter 905 and the fine filter 906 are all connected by pipelines. The pressure sensor 910 and the pressure gauge 6 are correspondingly arranged. Through the settings of the pressure gauge 6, the quartz sand filter 904, the activated carbon filter 905, the fine filter 906 and the pressure sensor 910, during use, the quartz sand filter 904, the activated carbon filter 905 and the fine filter 906 perform three-stage filtration on the raw water to ensure that the water entering the RO membrane 911 is relatively pure. At the same time, the pressure gauge 6 monitors the water pressure through the pressure sensor 910 to avoid affecting the filtration effect or equipment safety due to abnormal pressure.

[0026] Further, two groups of RO membranes 911 are arranged on the surface of the frame 1, and the two groups of RO membranes 911 are connected to each other by pipelines. Through the setting of the RO membranes 911, during use, the two groups of RO membranes 911 increase the contact area between the water and the membrane surface, improve the efficiency and processing capacity of reverse osmosis filtration. When one group of RO membranes 911 fails or its performance deteriorates, the other group of RO membranes 911 can still work normally, improving the stability and reliability of the equipment.

[0027] Further, the concentrated water pipe 912 and the clean water pipe 914 are both fixedly connected to the two groups of RO membranes 911. One end of the concentrated water pipe 912 is connected to the sewage discharge end 7, and one end of the clean water pipe 914 is connected to the water storage tank 1001. Through the settings of the sewage discharge end 7, the concentrated water pipe 912, the clean water pipe 914 and the water storage tank 1001, during the reverse osmosis process, the RO membranes 911 divide the water into concentrated water and pure water and discharge them through the concentrated water pipe 912 and the clean water pipe 914 respectively, enabling the reasonable diversion and treatment of water with different qualities and improving the working efficiency of the equipment.

[0028] Working principle: When sewage needs to be treated, first start the raw water pump 901 through the control panel 5, so that the sewage to be treated enters the quartz sand filter 904 through the water inlet 902 and the first pipeline 903. The quartz sand filter 904 is filled with filtering media such as quartz sand. When the sewage flows through, it can effectively remove larger particle impurities therein, such as sediment, suspended matter, etc. The preliminarily filtered sewage enters the activated carbon filter 905 through the pipeline. The activated carbon filter 905 adsorbs organic matters, different colors, peculiar smells, etc. in the sewage to further purify the sewage, and then flows into the fine filter 906 to perform high-precision filtration on the sewage to remove residual fine particles and impurities. The water filtered by the fine filter 906 enters the high-pressure pump 908 through the second pipeline 907. The high-pressure pump 908 pressurizes the water to make it reach the pressure required for reverse osmosis. At the same time, the pressure gauge 6 monitors the water pressure situation through the pressure sensor 910 to avoid affecting the filtration effect or equipment safety due to abnormal pressure. Then it is transported to two groups of RO membranes 911 through the third pipeline 909. The RO membranes 911 have very small pore diameters and only allow water molecules to pass through, while blocking most of the ions, organic matters and other impurities dissolved in the water. Due to the high-pressure effect, the water is forced to reverse osmosis through the RO membranes 911. A part of the water permeates through the RO membranes 911 to become pure water, enters the water storage tank 1001 through the clear water pipe 914 and the clear water valve 915, and the other part becomes concentrated water and is discharged from the sewage discharge end 7 through the concentrated water pipe 912 and the concentrated water valve 913, thus completing the reverse osmosis filtration of the sewage. When water is needed, start the pure water pump 1003 through the control panel 5. The water in the water storage tank 1001 flows through the fourth pipeline 1002 to the ultraviolet disinfection device 1004 and the post-activated carbon filter element 1005 in sequence under the action of pressure. The ultraviolet disinfection device 1004 uses ultraviolet rays to efficiently kill bacteria, viruses, etc. that may remain in the pure water to ensure the microbial safety of the pure water. The pure water after ultraviolet disinfection treatment continues to flow to the post-activated carbon filter element 1005 to further perform deep filtration and secondary adsorption on the pure water, and finally is discharged from the pure water discharge end 8 through the fifth pipeline 1006. At this time, the obtained pure water has extremely high purity and quality, can meet the high-standard pure water application scenarios, adapt to the fluctuating water use requirements, and at the same time ensure the water production quality.
