Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment nitrate adsorption treatment device. Background Technology

[0002] Traditional water treatment methods for nitrate adsorption utilize the selective permeability of semi-permeable membranes to retain nitrate ions under pressure, thereby separating water from pollutants.

[0003] This process has some drawbacks and disadvantages: 1. High energy consumption, requiring high-pressure operation, large equipment investment, and high membrane module cost; 2. The membrane is susceptible to fouling by suspended solids, organic matter, and microorganisms, requiring complex pretreatment, which increases costs; 3. It produces high-concentration concentrate (containing nitrates at 2-5 times the concentration of raw water), which is difficult to treat and poses a high risk of environmental pollution; 4. High operating costs, suitable for scenarios with high water quality requirements but small scale; 5. The process nodes are dispersed, requiring a large area and a long manufacturing and on-site construction cycle.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The self-priming pump 2 is connected to the adsorption column 1. The adsorption column 1 and the clear water tank 4 are connected by a first pipe 11. The dilute regeneration tank 5 and the concentrated regeneration tank 6 are located behind the adsorption column 1, and a partition is provided between the dilute regeneration tank 5 and the concentrated regeneration tank 6. The clear water tank 4 is located on top of the dilute regeneration tank 5 and the concentrated regeneration tank 6. The regenerated water pump 7 is located between the dilute regeneration tank 5 and the adsorption column 1 and is connected to the dilute regeneration tank 5 and the adsorption column 1. The regenerant circulation pump 3 is located between the concentrated regeneration tank 6 and the adsorption column 1 and is connected to the dilute regeneration tank 5 and the clear water tank 4.

[0019] See Figures 1-4Preferably, the self-priming pump 2 and the adsorption column 1 of this utility model are provided with a second pipe 12, through which the raw water is conveniently transported to the adsorption column 1.

[0020] See Figures 1-4 In addition, the base 10 of this utility model is provided with a high-flow filter 8. The high-flow filter 8 is connected to the self-priming pump 2 and the adsorption column 1 through the second pipe 12. The high-flow filter 8 can filter impurities in the raw water.

[0021] See Figures 1-4 Furthermore, the regenerated water pump 7 of this invention is connected to the dilute regeneration tank 5 and the adsorption column 1 through a third pipe 13, which facilitates the delivery of the regenerator to the interior of the adsorption column 1 for regeneration treatment of the adsorbent.

[0025] The working principle of this utility model: Raw water is pumped by self-priming pump 2, passes through high-flow filter 8, and then enters adsorption column 1. Nitrate impurities in the water are adsorbed by a special adsorbent in adsorption column 1, while the produced water enters clear water tank 4 under the driving force of self-priming pump 2.

[0026] After the equipment has been running for a period of time, the adsorbent will reach saturation and needs to be regenerated. At this time, sodium hydroxide regenerant is dissolved and prepared in the concentrated regeneration tank 6. After it is completely dissolved, it enters the dilute regeneration tank 5 through the regenerant circulation pump 3, and then enters the clear water tank 4. After being mixed with the clear water in the clear water tank 4, a regeneration solution that meets the requirements is prepared so that the device can be used in the regeneration state. Then, the sodium hydroxide regenerant enters the adsorption column 1 from the dilute regeneration tank 5 through the regeneration water pump 7 to regenerate the adsorbent.

Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
