Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a deep denitrification device for slightly polluted surface water and groundwater. Background Art

[0002] With the increase in the discharge of industrial wastewater and domestic sewage, the damage caused by polluted water to water resources will have very serious consequences. Therefore, it is necessary to effectively treat the sewage before discharge and then restrict its discharge after it meets the discharge standards. However, there are still certain pollution sources in the treated water, which will still have a certain impact on the composition of the water body. In addition, the sewage discharged in the early stage will remain in the soil and will also pollute the groundwater. The treatment of groundwater is relatively difficult and there is a lack of effective treatment measures.

[0003] After extensive searching, I discovered prior art: Publication No. CN206467119U, which discloses a groundwater nitrate and hardness removal device. The device includes a controller, a denitrification electron donor control device for controlling and dosing a denitrification electron donor, a water quality stabilization and uniform water distribution device for adjusting the dissolved oxygen concentration in the groundwater, a facultative oxic heterotrophic denitrification device for biological denitrification of the groundwater, an anaerobic autotrophic denitrification device for bioelectrochemical denitrification of the groundwater, a hardness removal device for reducing groundwater hardness, and a strong oxidizing device for oxidizing residual denitrification electron donors and denitrification reaction intermediates in the groundwater. By combining biological and electrochemical processes, this device effectively removes nitrate from groundwater and reduces groundwater hardness.

[0004] In summary, the harmful effects of excessive nitrogen and phosphorus in water bodies include eutrophication. The proliferation of blue-green algae and green algae causes oxygen depletion in the water, producing toxins that can kill aquatic organisms like fish and shrimp, harm human health, and deteriorate water quality. This not only impacts human life but also severely impacts industrial and agricultural production. Existing water denitrification equipment is mostly suitable for surface water and requires pumping equipment for continuous treatment. This not only requires a large processing workload and consumes significant resources, but also prevents traditional denitrification methods from being applied to groundwater, resulting in poor denitrification results.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 3 , the present invention provides two embodiments:

[0023] Example 1:

[0024] A deep denitrification system for slightly polluted surface water and groundwater includes a float tank 1, a float tank 4, a positioning pipe 5, an extension pipe 6, a delivery pipe 7, a tapered pipe 8, a first connecting pipe 14, a second connecting pipe 16, and a controller 22. The upper end of the float tank 1 comprises a liquid tank 10, while the lower end comprises a control tank 15. The controller 22 is mounted on the inner wall of the bottom end of the control tank 15. A shunt pipe 3 is connected to the outer wall of one side of the float tank 1. A feed pipe 2 is disposed above the float tank 1, and the upper ends of the shunt pipes 3 are both connected to the feed pipe 2. A first solenoid valve 9 is mounted on the surface of the shunt pipe 3, and the first solenoid valve 9 is connected to the controller 22. A first connecting pipe 14 and a second connecting pipe 16 are respectively provided inside the control chamber 15. A second solenoid valve 11 is installed on the surface of the first connecting pipe 14, and the second solenoid valve 11 is connected to the controller 22. One end of the first connecting pipe 14 passes through the surface of both sides of the float tank 1, and the float pipe 4 is connected to the first connecting pipe 14. The surface of the float pipe 4 is embedded with equidistantly distributed first nozzles 13, and the outer wall of the first nozzle 13 is sleeved with a floating block 12.

[0025] When denitrifying surface water, since surface water treatment is relatively easy, the staff can remove the extension pipe 6 and only retain the float tank 1 and the float tube 4. The float tube 4 floats on the surface of the water body, and the first nozzle 13 sprays the denitrification treatment agent into the water body. Through the natural flow of the water body, the denitrification agent is evenly diffused in the water body. Combined with the float tank 1 being evenly arranged along the surface of the water body, the surface water can be fully covered for denitrification treatment.

[0026] Example 2:

[0027] The bottom of the float tank 1 is equipped with a positioning tube 5, the lower end of which is fitted with an extension tube 6. Floating tubes 4 are symmetrically arranged on the outer walls of both sides of the float tank 1, and delivery pipes 7 are installed within each extension tube 6. A tapered tube 8 is installed at the bottom of the extension tube 6. Engaging threaded openings 19 are provided at the bottom end of the positioning tube 5, both ends of the extension tube 6, and the upper end of the tapered tube 8. Rubber sleeves 20 are fitted over the joints between the positioning tube 5, the extension tube 6, and the tapered tube 8. The upper ends of the first connecting tube 14 and the second connecting tube 16 are both connected to the interior of the bottom end of the liquid tank 10. The lower end of the second connecting tube 16 extends through the interior of the positioning tube 5. Threaded sleeves 17 are provided at the bottom ends of the second connecting tube 16 and the delivery pipe 7. The extension tubes 6 are installed according to the depth of the groundwater. The extension tubes 6 can be rotatably connected to each other via threaded openings 19, while the delivery pipe 7 is connected via threaded sleeves 17, solving the technical problem of groundwater denitrification.

[0028] The outer wall of the delivery pipe 7 is installed with equally spaced second nozzles 24, and the second nozzles 24 all penetrate the outer wall of the extension pipe 6. The surface of the delivery pipe 7 is installed with equally spaced third solenoid valves 23, and the third solenoid valves 23 are located above the second nozzles 24. The bottom ends of the positioning pipe 5 and the extension pipe 6 are both provided with a connecting seat 18, and the two ends of the connecting seat 18 are respectively connected to a transmission line 21. The two ends of the transmission line 21 are respectively connected to the controller 22 and the third solenoid valve 23. The transmission line 21 forms a complete signal transmission route through the connecting seat 18, so that the controller 22 can control the third solenoid valve 23 to achieve the on-off state of the second nozzles 24 at different depths. The denitrification treatment agent is sprayed through the second nozzle 24 and undergoes a comprehensive denitrification reaction as the groundwater flows, covering a wider groundwater area. Through the natural diffusion of groundwater, effective water denitrification treatment is carried out, which not only saves resources spent on treatment, but also achieves a good denitrification effect.

[0029] In actual application, it can be flexibly arranged according to the treatment methods of groundwater and surface water. The float tank 1 is evenly distributed in the surface water range and the groundwater range, so that the float tank 1 fully covers the area of ​​the treated water body, and the extension pipe 6 is installed according to the depth of the groundwater. The denitrification treatment agent can be fully dispersed in the soil layer where the groundwater is located. As the groundwater flows, a comprehensive denitrification reaction is carried out, covering a wider groundwater area and solving the technical difficulties of groundwater denitrification. At the same time, the float tube 4 can float on the surface of the water and spray the denitrification agent into the surface water body. Through the natural diffusion of the water body, effective water denitrification treatment is carried out, which not only saves resources spent on treatment, but also achieves a good denitrification effect.
