[0002] Constructed wetland denitrification of wastewater is to treat wastewater containing nitrogen pollutants through an artificial wetland system. Constructed wetlands are a new type of wastewater treatment method that emerged in the 1970s. They use the interaction between substrates, aquatic plants and microorganisms to remove harmful substances in wastewater, including nitrogen pollutants, through filtration, adsorption, co-precipitation, ion exchange, plant absorption and microbial decomposition.

[0003] After searching, a Chinese patent discloses an artificial wetland denitrification sewage treatment device (announcement number is CN216209033 U). This patented technology installs an auxiliary component inside the box. When the weight of the sewage is greater than the elastic force of the spring part, the spring part drives the baffle down to discharge the sewage into the detection box. After the sewage is discharged, the spring part drives the baffle up to seal, thereby realizing the function of automatic sewage discharge. There is no need for staff to manually discharge the sewage, reducing the workload of the staff. However, in the technical solution of the above patent document; the area is small when the liquid medicine is sprinkled, and the diffusion of the liquid medicine in the pool is slow, resulting in waste of liquid medicine, affecting the mixing of the liquid medicine and the purification effect of the sewage.

[0004] Therefore, an artificial wetland denitrification sewage treatment device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4As shown, an artificial wetland denitrification sewage treatment device comprises: an installation box 3, the inner wall of which is fixedly connected to a water storage tank 2 and a drainage pumping mechanism 1, the upper end of the installation box 3 is fixedly connected to a spraying nozzle 4, and the spraying nozzle 4 is connected to the inside of the drainage pumping mechanism 1; a stirring and mixing mechanism 5, which is used to stir the liquid sprayed by the spraying nozzle 4 and is arranged on one side of the water storage tank 2; an upper shielding component 6, which is used to shield and protect the stirring and mixing mechanism 5 and is arranged on the inner side of the water storage tank 2; wherein the stirring and mixing mechanism 5 comprises a reciprocating component 501 arranged on the upper side of the installation box 3, and a synchronous rotation component 502 is arranged on one side of the reciprocating component 501. When the wetland sewage is purified by this device, the sewage is put into the water storage tank 2, and then the sewage is discharged through the wetland pumping mechanism 1. The ground is purified and the sewage is purified by spraying liquid medicine through the spraying nozzle 4. At this time, the reciprocating moving component 501 is started to reciprocate in the water tank 2. The synchronous rotation component 502 makes the reciprocating moving component 501 rotate while reciprocating to increase the stirring effect. The upper shielding component 6 can shield and protect the upper side of the stirring and mixing mechanism 5 to prevent falling debris from entering and causing jamming. The drainage pump medicine mechanism 1 includes an internal liquid medicine storage box output pump and an internal automatic sewage discharge part. The drainage pump medicine mechanism 1 has the same structure as the automatic sewage discharge and liquid medicine output part in the comparative document, and will not be elaborated here. The spraying nozzle 4 can spray and output the liquid medicine in the drainage pump medicine mechanism 1. The various components of the stirring and mixing mechanism 5 are all arranged on the water surface and at a certain distance from the water surface, and will not entangle plants.

[0023] like Figure 2 and Figure 3As shown, the reciprocating assembly 501 includes a driving motor 5011 fixedly connected to the upper end of the installation box 3, and a reciprocating screw 5012 is fixedly connected to the output end of the driving motor 5011. The reciprocating screw 5012 is rotatably connected to the inner wall of the water tank 2. A pushing nut 5013 is threadedly connected to the surface of the reciprocating screw 5012, and a rotating rod 5014 is rotatably connected to the lower end of the pushing nut 5013. A stirring rod 5015 is fixedly connected to the surface of the rotating rod 5014. When the spray nozzle 4 is started and the sewage in the water tank 2 needs to be stirred and mixed to increase the purification effect, the driving motor 5011 can be manually started at this time, so that the driving motor 5011 drives the reciprocating screw 5012 to rotate. The reciprocating screw 5012 is a form of a three-dimensional cam pair, which can drive the pushing nut 5013 to reciprocate without changing the rotation direction of the main shaft. There are spiral patterns on the reciprocating screw 5012, and the pushing nut 5013 is a part that matches these patterns. When the reciprocating screw 5012 rotates, the pushing nut 5013 will move along the texture on the screw, thereby realizing axial reciprocating motion. The reciprocating screw 5012 drives the pushing nut 5013 to move back and forth, and the pushing nut 5013 drives the rotating rod 5014 and the stirring rod 5015 to move back and forth, driving the water to mix, thereby increasing the purification effect of the spraying liquid of the spray nozzle 4. The inner wall of the water tank 2 is fixedly connected to the limiting rod 5016, and the pushing nut 5013 is slidingly connected to the surface of the limiting rod 5016. When the reciprocating screw 5012 rotates to drive the pushing nut 5013 to slide back and forth, the pushing nut 5013 is easy to shake with the rotation of the reciprocating screw 5012. At this time, the sliding of the pushing nut 5013 is limited by the limiting rod 5016, so that the pushing nut 5013 will not shake when sliding.

[0024] like Figure 2 and Figure 3As shown, the synchronous self-rotating assembly 502 includes a gear 5021 fixedly connected to the surface of the rotating rod 5014, and a rack 5022 is fixedly connected to the inner wall of the water storage tank 2. The gear 5021 is meshed with the rack 5022. When the push nut 5013 slides back and forth, the rotating rod 5014 and the gear 5021 are driven to slide back and forth. At this time, the gear 5021 slides on the surface of the rack 5022. Through the meshing effect of the gear 5021 and the rack 5022, the gear 5021 and the rotating rod 5014 rotate to stir. The rod 5015 rotates to stir and mix the sewage in the water storage tank 2. When the mixing is completed, the liquid pump in the drainage pump medicine mechanism 1 and the drive motor 5011 are manually closed to stop spraying. The drive motor 5011 is a three-phase asynchronous motor. For the staff in this technical field, the drive motor 5011 is a prior art and will not be described in detail here. The inner wall of the water storage tank 2 is fixedly connected to the limit frame 5023, and the rotating rod 5014 is slidably connected to the inner wall of the limit frame 5023. The limit frame 5023 can make the gear 5021 and The meshing of the rack 5022 is more stable and is not easy to disengage and collide with the teeth. When the gear 5021 and the rotating rod 5014 rotate, the rotating rod 5014 is easy to swing, so that the gear 5021 and the meshing of the rack 5022 are disengaged. At this time, the sliding of the rotating rod 5014 is limited by the limit frame 5023, so that the rotating rod 5014 is not easy to swing, which can make the meshing of the gear 5021 and the rack 5022 more stable and not easy to disengage and collide with the teeth. The upper shielding component 6 includes a fixed connection to the inner wall of the water storage tank 2 Two shielding covers 601 are provided, and a mounting seat 602 is arranged on the upper side of the stirring rod 5015. The mounting seat 602 is slidably connected to the inner wall of the shielding cover 601. The mounting seat 602 can shield and protect the upper side of the stirring and mixing mechanism 5 to prevent debris from entering the stirring and mixing mechanism 5 and causing a jam. The inner wall of one shielding cover 601 is a through hole, and the inner walls of the two shielding covers 601 are provided with arc-shaped protrusions. Through the shape of the shielding cover 601, dust and debris can fall directly downward inside the shielding cover 601 without accumulation.

[0025] When the utility model is in use, when the device is used to purify wetland sewage, the sewage is placed in the water storage tank 2, and then the sewage is purified by spraying liquid medicine through the wetland purification nozzle 4 at the same time. At this time, the drive motor 5011 is manually started, so that the drive motor 5011 drives the reciprocating screw 5012 to rotate, and the reciprocating screw 5012 drives the pushing nut 5013 to reciprocate, and the pushing nut 5013 drives the rotating rod 5014 and the stirring rod 5015 to reciprocate, contacting a larger area in the water storage tank 2, To increase the purification effect of the liquid sprayed by the spray nozzle 4, when the push nut 5013 is pushed back and forth, the rotating rod 5014 and the gear 5021 are driven to slide back and forth. At this time, the gear 5021 slides on the surface of the rack 5022. Through the meshing effect of the gear 5021 and the rack 5022, the gear 5021 and the rotating rod 5014 rotate, and the stirring rod 5015 rotates to stir and mix the sewage in the water tank 2. When the mixing is completed, the liquid pump in the drainage pump mechanism 1 and the drive motor 5011 are manually closed to stop spraying.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
