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. Example

[0024] See Figures 1 to 3As shown, an integrated perchlorate treatment device includes a storage tank 2 connected to a sewage discharge pipe 1, a booster pump 3 installed in the storage tank, an integral housing 4 installed at the output end of the booster pump, an air flotation unit 5 installed inside the integral housing and connected to the output end of the booster pump, an intermediate water tank 6 installed inside the integral housing and connected to the output end of the air flotation unit, a quartz sand filter 7 connected to the intermediate water tank, an activated carbon filter 8 connected to the quartz sand filter, an ion exchanger 9 connected to the activated carbon filter, a pipeline mixer 10 connected to the ion exchanger, a precision filter 11 connected to the pipeline mixer, and a two-stage reverse osmosis structure 12 connected to the precision filter; in this embodiment, the air flotation unit is an existing type. The conventional structure of the technology is simply applied and therefore not described in detail. The quartz sand filter, activated carbon filter, ion exchanger, pipeline mixer, and precision filter are all conventional structures in existing technology, primarily used for filtration operations. All of these structures are housed within a single integrated enclosure, ensuring protection from external interference and weathering, thus improving safety. The completely sealed enclosure prevents unauthorized entry and potential accidents, extends the overall lifespan of the structure, avoids material waste, allows for recycling, and exhibits high stability. It only requires periodic addition of appropriate chemicals, produces few byproducts, and contributes to improved wastewater treatment efficiency and effectiveness, making it highly versatile. In this embodiment, the ion exchanger contains alkaline anion exchange resin for acid-base neutralization and salinity reduction of the water.

[0025] In this embodiment, the bottom end of the air flotation machine is connected to a sludge tank 13 via a conduit, and a plate filter press 14 is installed at the output end of the sludge tank; through the above structure, sludge treatment can be achieved.

[0026] Furthermore, several reagent storage tanks 15 are provided, and these tanks are connected to a water storage tank, an air flotation machine, an ion exchanger, and a pipeline mixer via output pipes. In this embodiment, the reagent storage tanks include a lime spraying tank 151, a PAC dosing storage tank 152, a PAM dosing storage tank 153, a NaOH dosing storage tank 154, a reducing agent dosing storage tank 155, and a scale inhibitor dosing storage tank 156. The PAC dosing storage tank, PAM dosing storage tank, NaOH dosing storage tank, and reducing agent dosing storage tank are all connected to the air flotation machine. The PAC dosing agent is polyaluminum chloride, the PAM dosing agent is polyacrylamide, and the reducing agent dosing agent is sodium bisulfite. The NaOH dosing storage tank is connected to the ion exchanger. The scale inhibitor dosing storage tank is connected to the pipeline mixer; the lime powder from the lime spraying tank is sprayed into the water storage tank. Furthermore, the NaOH dosing storage tank contains 5% NaOH reagent.

[0027] In this embodiment, the dual-stage reverse osmosis structure includes a first pump body 121, a first RO reverse osmosis unit 122, a second pump body 123, and a second RO reverse osmosis unit 124. The input end of the first pump body is connected to the output end of the precision filter, and the output end of the first pump body extends into the inlet end of the first RO reverse osmosis unit. The input end of the second pump body is connected to the output end of the first RO reverse osmosis unit, and the output end of the second pump body extends into the inlet end of the second RO reverse osmosis unit. The concentrate ends of the first and second RO reverse osmosis units extend into the water storage tank through return pipes.

[0028] In operation, the water storage tank is first treated with alkali, and then the wastewater is pumped to the air flotation machine to treat colloidal suspended solids, silt, etc. The resulting clear water is then treated with a reducing agent and pumped to the membrane treatment stage. The by-products of the air flotation machine are pressed into briquettes by a plate filter press. The clear water is further treated with quartz sand sedimentation to reduce silt and colloids. Activated carbon adsorbs perchloric acid in the water, as well as adsorbs discoloration and odor. Alkaline resin neutralizes the acid and alkali of the water and reduces salinity, while removing scale. Scale inhibitors are added to ensure that the front of the dual-stage reverse osmosis structure does not become clogged or scaled. After two filtrations by the dual-stage reverse osmosis structure, the water meets the discharge standards.

[0029] This utility model has positive effects: Its structure is rationally designed, incorporating an air flotation unit, intermediate water tank, quartz sand filter, activated carbon filter, ion exchanger, pipeline mixer, precision filter, and a dual-stage reverse osmosis structure within a single housing. Furthermore, it includes several reagent storage tanks, preventing external interference and accidental operation by unauthorized personnel, thus enhancing overall safety and extending the overall structural lifespan. This prevents material waste and allows for long-term recycling, improving wastewater treatment efficiency, reducing byproducts, lowering treatment costs, and enhancing applicability.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
