After the sewage after the action of flocculant is left to settle inside the sterilization tank, most of the suspended matter will settle to the bottom, and the upper part of the sewage will be relatively clear. At this time, the ultraviolet lamp can be turned on to allow ultraviolet rays to irradiate the sewage. Ultraviolet radiation can destroy the DNA or RNA of microorganisms, making them lose their ability to replicate, thus achieving thorough sterilization and disinfection. Combining the above steps, the entire treatment process can purify sewage more efficiently and comprehensively to ensure that the effluent meets the emission standards.

The mixing box 2 is used to mix copper dioxide and additives to form a sterilization solvent. The feed box 16 is used for sewage to enter. The filter box 12 allows the sewage to be filtered after sterilization in the sterilization tank 1.

[0025] The top of the mixing box 2 is connected with a plurality of feeding pipes 3, the surface of the mixing box 2 is connected with a first solenoid valve 4, the surface of the first solenoid valve 4 is connected with a liquid extraction pipe 6, the surface of the liquid extraction pipe 6 is installed with a flow meter 5, one end of the liquid extraction pipe 6 is connected with a first delivery pump 7, and the liquid outlet end of the first delivery pump 7 is connected with the surface of the sterilization tank 1 through a pipeline;

[0026] Diluted sulfuric acid and copper dioxide can be added to the mixing box 2 through the feeding pipe 3. After the dilute sulfuric acid and copper dioxide are fused and diluted, a copper sulfate salt solution can be formed. Since it contains free copper ions, it can effectively kill bacteria, fungi and other microorganisms in the water. The copper salt solution can be transported to the sterilization tank 1 by opening the first solenoid valve 4 and the first delivery pump 7. The flowmeter 5 can monitor the output copper salt solution to avoid negative effects caused by excessive copper ion delivery.

[0027] An ultraviolet lamp 8 is fixed on the top of the inner wall of the sterilization tank 1, a feed pipe is connected to the top of the sterilization tank 1, a slag discharge valve 9 is connected to the bottom of the sterilization tank 1, a second solenoid valve 10 is connected to the surface of the sterilization tank 1, a second delivery pump 11 is connected to the surface of the second solenoid valve 10 through a pipeline, and the discharge end of the second delivery pump 11 is connected to the top of the filter box 12 through a pipeline;

[0028] After the mixed copper salt solvent and sewage are added to the sterilization tank 1, the copper salt solvent will release a large amount of copper ions in the sewage. Copper ions have a broad-spectrum bactericidal ability and can destroy the integrity of microbial cell membranes, interfere with their metabolic processes, and cause the death of microorganisms. At the same time, it can also inhibit the growth of algae, and has a better treatment effect on agricultural and aquaculture sewage. The presence of copper ions can accelerate the coagulation and sedimentation of suspended particles, thereby improving the efficiency of sewage treatment. Then, flocculants can be added to the sterilization tank 1 through a feed pipe, and the sewage and flocculants are mixed. The flocculants can aggregate tiny suspended particles into larger flocs for easy precipitation, improve the transparency of water quality, and improve the efficiency of subsequent ultraviolet lamps 8. Killing effect: after the sewage after the action of the flocculant is left to settle inside the sterilization tank 1, most of the suspended matter will settle to the bottom, and the upper part of the sewage will be relatively clear. At this time, the ultraviolet lamp 8 can be turned on to allow ultraviolet rays to irradiate the sewage. The ultraviolet radiation can destroy the DNA or RNA of microorganisms, causing them to lose their replication ability, thereby achieving thorough sterilization and disinfection. Combining the above steps, the entire treatment process can purify the sewage more efficiently and comprehensively, ensuring that the effluent meets the emission standards. After the sewage is killed by the ultraviolet lamp 8, the second solenoid valve 10 and the second delivery pump 11 can be opened to transport the sewage to the inside of the filter box 12, and the slag discharge valve 9 can be opened to discharge the flocculants deposited at the bottom of the inner wall of the sterilization tank 1.

[0029] The filter box 12 is provided with a blocking filter 13 and a filter plate 14, the bottom of the filter box 12 is connected to a drain valve 15, a dirt filter 17 is fixed inside the feed box 16, the left side of the surface of the feed box 16 is connected to a water inlet pipe, the surface of the feed box 16 is connected to a third delivery pump 18, and the discharge end of the third delivery pump 18 is connected to the surface of the sterilizing tank 1 through a pipeline;

[0030] Sewage can be added to the feed box 16 through the water inlet pipe, and after being blocked and filtered by the dirt filter 17, it is transported to the inside of the sterilization tank 1 through the third delivery pump 18. The blocking filter 13 can filter the sewage after sedimentation again to intercept flocculants that may be mixed in the sewage, and the filter plate 14 can adsorb and filter the sewage to remove harmful substances in the sewage and improve the sewage purification effect. Opening the drain valve 15 can discharge the treated sewage.

[0031] Furthermore, a first motor 21 is fixed on the top of the sterilizing tank 1, and the output shaft of the first motor 21 passes through the interior of the sterilizing tank 1 and is fixed with a first stirring rod 22. A second motor 23 is fixed on the top of the mixing box 2, and the output shaft of the second motor 23 passes through the interior of the mixing box 2 and is fixed with a second stirring rod 24.

[0032] When the first motor 21 is started, it will drive the first stirring rod 22 to rotate, which can improve the reaction effect of sewage with the treatment solvent and flocculant inside the sterilization tank 1. When the second motor 23 is started, it can drive the second stirring rod 24 to rotate, thereby improving the mixing effect of copper dioxide and dilute sulfuric acid inside the mixing box 2.

[0033] Furthermore, there are two trash filter screens 17, and the surface mesh of the left trash filter screen 17 is larger than that of the right trash filter screen 17;

[0034] Through this design, the left-side dirt filter 17 can first intercept larger impurities, while the right-side dirt filter 17 can provide a further interception effect, thereby improving the filtering effect of impurities in sewage.

[0035] Furthermore, a plurality of mounting shells 26 are fixed to the inner wall of the filter box 12, and a limiting groove 27 is provided on the inner wall of the mounting shell 26. The front side of the surface of the mounting shell 26 is provided with an open structure, and the blocking filter screen 13 and the filter plate 14 are both located inside the limiting groove 27;

[0036] The blocking filter 13 and the filter plate 14 can obtain a limiting effect inside the limiting groove 27 on the surface of the mounting shell 26, so that when the sewage passes through the blocking filter 13 and the filter plate 14, the blocking filter 13 and the filter plate 14 are not prone to shaking. The front side of the mounting shell 26 is open, so that the blocking filter 13 and the filter plate 14 can be taken out from the inside of the mounting shell 26.

[0037] Furthermore, there are two filter plates 14, the upper filter plate 14 is an ion exchange resin filter plate, the lower filter plate 14 is an activated carbon filter plate, and the blocking filter screen 13 is a microporous ceramic filter screen;

It can provide fine filtration accuracy and is suitable for removing solid particles and suspended matter after flocculation in sewage. The ion exchange resin filter plate can remove ions in water, including metal ions. For wastewater containing copper sulfate, ion exchange resin can adsorb copper ions, thereby reducing the concentration of heavy metals in the water. Activated carbon is a highly porous carbon material with a huge specific surface area. It can remove organic matter, pigments, odors and some metal ions in water by physical adsorption. For sewage treated with copper sulfate, it can further remove residual organic impurities and other pollutants and copper ions in sewage.

[0039] Furthermore, a plurality of cleaning doors 19 are hingedly connected on the top of the feed box 16 and the surface of the filter box 12, and sealing rings are fixed on the surface of the cleaning door 19;

[0040] By opening the cleaning door 19 on the surface of the feed box 16 , the surface of the dirt filter 17 can be cleaned, and by opening the cleaning door 19 on the surface of the filter box 12 , the blocking filter 13 and the filter plate 14 can be pulled out from the inside of the mounting shell 26 .

[0041] Furthermore, a transparent partition 20 is fixed on the top of the inner wall of the sterilizing tank 1, and a transparent observation window 25 is embedded and fixed on the surface of the mixing box 2, and a scale line is set on the surface of the transparent observation window 25;

[0042] The provision of the transparent partition 20 prevents sewage from splashing onto the surface of the ultraviolet lamp 8 during the stirring and mixing process, while the provision of the transparent observation window 25 and the scale lines enables the operator to more accurately control the addition of materials inside the mixing box 2.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
