Description

Technical Field

[0001] The utility model relates to the technical field of ecological wetland purification ponds, and specifically relates to an ecological wetland purification pond. Background Technique

[0002] An ecological wetland purification pond is an artificial structure that simulates a natural wetland system and is used to treat sewage and improve water quality. They remove pollutants through physical, chemical, and biological processes such as sedimentation, filtration, adsorption, plant absorption, and microbial metabolism. After a large number of searches, the publication number CN211946719U discloses an ecological wetland purification pond for aquaculture sewage, which uses the activities of submerged plants and emergent plants to reduce pollutants such as nitrogen and phosphorus in aquaculture sewage, effectively improving the sewage treatment efficiency of the wetland purification pond and having a low investment cost.

[0003] However, when the device in the prior art is in use, the water levels on both sides of the baffle inside the purification pond body are basically flat. As a result, when treating water, if the water inflow is small, the pressure difference on both sides is small, resulting in slow water flow and affecting the sewage treatment speed and efficiency. For this reason, an ecological wetland purification pond is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an ecological wetland purification pond, which has the advantages of improving the sewage treatment speed and efficiency, and solves the problem of poor water fluidity on both sides of the baffle in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an ecological wetland purification pond, including a discharge cylinder, and purification bins are connected and installed on the outer side of the discharge cylinder in an annular array;

[0006] A sealing cover is fixedly installed on the top of the discharge cylinder, a water suction pipe is connected and installed inside the sealing cover, a water pumping mechanism is connected and installed on the top of the sealing cover, and the bottom of the discharge cylinder is flush with the top of the purification bins;

[0007] The water pumping mechanism includes a vacuum water pump, a water inlet pipe is connected and installed on one side of the front of the vacuum water pump, the end of the water inlet pipe away from the vacuum water pump is connected and installed with the top of the sealing cover, and a drain pipe is connected and installed on the other side of the front of the vacuum water pump.

[0008] Preferably, the discharge cylinder is filled with five-stage filtration and six-stage filtration from bottom to top, and communication pipes are connected and installed on the outer bottom of the discharge cylinder in an annular array. In the design, the discharge cylinder is filled with five-stage filtration and six-stage filtration from bottom to top, realizing a multi-level filtration system. This design not only improves the filtration efficiency but also extends the maintenance cycle, and pollutants are gradually removed when passing through different levels of filter materials.

[0009] Preferably, the fifth-stage filtration and the sixth-stage filtration are respectively a coarse sand layer and a fine sand layer, and the bottom end of the water extraction pipe extends into the sixth-stage filtration and is connected with a filtration component installed. In the design, the fifth-stage filtration and the sixth-stage filtration respectively adopt a coarse sand layer and a fine sand layer. This layering strategy optimizes the filtration effect, enabling larger particles to be intercepted by the coarse sand layer first, while the fine sand layer captures finer particles. The filtration component at the bottom end of the water extraction pipe further ensures the purity of the water quality. Through this fine filtration, the quality of the discharged water is significantly improved.

[0010] Preferably, the purification chamber is filled with a first-stage filtration, a second-stage filtration, a third-stage filtration, and a fourth-stage filtration from top to bottom. An opening is made at the bottom of one side of the purification chamber and is connected with a drainage trough installed. In the design, the first-stage filtration to the fourth-stage filtration in the purification chamber constitute a vertical filtration sequence, and each stage is designed for specific pollutants, thereby achieving efficient pollutant removal. Moreover, it not only enhances the physical filtration ability but also improves the purification efficiency through the biological action of plants and the chemical adsorption of the soil.

[0011] Preferably, the first-stage filtration, the second-stage filtration, the third-stage filtration, and the fourth-stage filtration are respectively a submerged plant layer, a soil matrix layer, a stainless steel metal filter screen layer, and a stone slag layer, and green plants are planted in the first-stage filtration. In the design, the green plants planted in the first-stage filtration not only add a touch of green to the purification pond, but more importantly, these plants absorb nutrients through their roots, promoting the biological purification of the water quality. This ecological engineering method combines natural purification with artificial filtration, improving the sustainability and aesthetics of the system.

[0012] Preferably, the drainage trough is connected and installed with a connecting pipe, and the length of the drainage trough matches the size of one side of the purification chamber. In the design, the connected installation of the drainage trough and the connecting pipe ensures that the purified water can smoothly drain from the purification chamber. This design simplifies the water discharge process, reduces the hydraulic resistance, and improves the efficiency of water body flow. The length of the drainage trough matches the size of one side of the purification chamber, and this precise size matching ensures the uniformity and continuity of the water body during the discharge process.

[0013] Preferably, the water pumping mechanism is fixedly installed on one side of the purification chamber, and the water inlet pipe on the water pumping mechanism passes through above the purification chamber. In the design, the fixed installation of the water pumping mechanism and the design of the water inlet pipe enable the water pumping mechanism to efficiently extract the treated water from the purification chamber. This layout not only improves the water pumping efficiency but also facilitates operation and maintenance because the position of the water pumping mechanism is easily accessible, and the path design of the water inlet pipe reduces the head loss, ensuring the smooth flow of the water body.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] Inside the inner side of the sealing cover at the top of the discharge cylinder in this utility model, a water suction pipe is installed. This design enables the water pumping mechanism to directly act on the water body in the discharge cylinder. Through the suction effect of the water suction pipe, the fluidity of the water body is enhanced. The vacuum water pump in the water pumping mechanism can effectively generate negative pressure, thereby forming a suction force in the discharge cylinder. This suction force helps to accelerate the flow rate of the water body and improve the transfer efficiency of the water body from the purification chamber to the discharge cylinder. The vacuum water pump sucks in the water body through the water inlet pipe and discharges the treated water through the drain pipe. At the same time, the setting of the drain pipe helps to maintain the water level in the discharge cylinder and avoid affecting the water flow due to too high a water level. The design that the bottom of the discharge cylinder is flush with the top of the purification chamber helps to maintain the water pressure balance between the two parts, thereby reducing the resistance of the water flow and improving the fluidity of the water body. The water pumping mechanism is fixedly installed on one side of the purification chamber. This layout makes the operation of the water pumping mechanism more stable and also facilitates maintenance and monitoring, ensuring the efficient operation of the water pumping mechanism and achieving the effect of improving the sewage treatment speed and efficiency.

[0021] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0022] Embodiment 1

[0023] As Figure 1 、 Figure 2, Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 , an embodiment provided by the present utility model is an ecological wetland purification tank, a discharge cylinder 3, and purification bins 1 are connected and installed in an annular array on the outer side of the discharge cylinder 3;

[0024] A sealing cover 31 is fixedly installed at the top of the discharge cylinder 3. A water suction pipe 32 is connected and installed inside the sealing cover 31. A water pumping mechanism 4 is connected and installed at the top of the sealing cover 31. The bottom of the discharge cylinder 3 is flush with the top of the purification bin 1;

[0025] The water pumping mechanism 4 includes a vacuum water pump 41. One side of the front of the vacuum water pump 41 is connected and installed with a water inlet pipe 42. The end of the water inlet pipe 42 away from the vacuum water pump 41 is connected and installed with the top of the sealing cover 31. The other side of the front of the vacuum water pump 41 is connected and installed with a drain pipe 43.

[0026] Specifically, a water suction pipe 32 is installed inside the sealing cover 31 at the top of the discharge cylinder 3. This design enables the water pumping mechanism 4 to directly act on the water body in the discharge cylinder 3. Through the suction effect of the water suction pipe 32, the fluidity of the water body is enhanced. The vacuum water pump 41 in the water pumping mechanism 4 can effectively generate negative pressure, thereby forming a suction force in the discharge cylinder 3. This suction force helps to accelerate the flow rate of the water body and improve the transfer efficiency of the water body from the purification bin 1 to the discharge cylinder 3. The vacuum water pump 41 sucks in the water body through the water inlet pipe 42 and discharges the treated water through the drain pipe 43. At the same time, the setting of the drain pipe 43 helps to maintain the water level in the discharge cylinder 3 and avoid affecting the water flow due to too high a water level. The design that the bottom of the discharge cylinder 3 is flush with the top of the purification bin 1 helps to maintain the water pressure balance between the two parts, thereby reducing the resistance of the water flow and improving the fluidity of the water body. The water pumping mechanism 4 is fixedly installed on one side of the purification bin 1. This layout makes the operation of the water pumping mechanism 4 more stable, and at the same time is convenient for maintenance and monitoring, ensuring the efficient operation of the water pumping mechanism 4, achieving the effect of improving the sewage treatment speed and efficiency.

[0027] Embodiment Two

[0028] In order to achieve multi-stage filtration of the water body, as Figure 2 and Figure 3 shown, in this embodiment, a five-stage filter 34 and a six-stage filter 35 are filled in the discharge cylinder 3 from bottom to top. Connecting pipes 36 are connected and installed in an annular array at the bottom of the outer side of the discharge cylinder 3. In the design, a five-stage filter 34 and a six-stage filter 35 are filled in the discharge cylinder 3 from bottom to top, realizing a multi-level filtration system. This design not only improves the filtration efficiency but also extends the maintenance cycle. Pollutants are gradually removed when passing through different levels of filter materials.

[0029] Furthermore, the fifth-stage filter 34 and the sixth-stage filter 35 are a coarse sand layer and a fine sand layer respectively. The bottom end of the water extraction pipe 32 extends into the sixth-stage filter 35 and is connected with a filter component 33 installed. In the design, the fifth-stage filter 34 and the sixth-stage filter 35 adopt a coarse sand layer and a fine sand layer respectively. This layering strategy optimizes the filtering effect, enabling larger particles to be intercepted by the coarse sand layer first, while the fine sand layer captures finer particles. The filter component 33 at the bottom end of the water extraction pipe 32 further ensures the purity of the water quality. Through this fine filtration, the quality of the discharged water is significantly improved.

[0030] Furthermore, the purification chamber 1 is filled with a first-stage filter 11, a second-stage filter 12, a third-stage filter 13, and a fourth-stage filter 14 from top to bottom. An opening is made at the bottom of one side of the purification chamber 1 and is connected with a drainage trough 15 installed. In the design, the first-stage filter 11 to the fourth-stage filter 14 in the purification chamber 1 constitute a vertical filtering sequence, and each stage is designed for specific pollutants, thus achieving efficient pollutant removal. Moreover, it not only enhances the physical filtering ability but also improves the purification efficiency through the biological action of plants and the chemical adsorption of the soil.

[0031] Furthermore, the first-stage filter 11, the second-stage filter 12, the third-stage filter 13, and the fourth-stage filter 14 are a submerged plant layer, a soil matrix layer, a stainless steel metal filter mesh layer, and a stone slag layer respectively. Green plants 2 are planted in the first-stage filter 11. The green plants 2 planted in the first-stage filter 11 in the design not only add a touch of green to the purification pond, but more importantly, these plants absorb nutrients through their roots, promoting the biological purification of the water quality. This ecological engineering method combines natural purification with artificial filtration, improving the sustainability and aesthetics of the system.

[0032] Furthermore, the drainage trough 15 is connected and installed with a connecting pipe 36, and the length of the drainage trough 15 matches the size of one side of the purification chamber 1. In the design, the connected installation of the drainage trough 15 and the connecting pipe 36 ensures that the purified water can smoothly drain from the purification chamber 1. This design simplifies the water discharge process, reduces the hydraulic resistance, and improves the efficiency of water body flow. The length of the drainage trough 15 matches the size of one side of the purification chamber 1. This precise size matching ensures the uniformity and continuity of the water body during the discharge process.

[0033] Furthermore, the water pumping mechanism 4 is fixedly installed on one side of the purification chamber 1, and the water inlet pipe 42 on the water pumping mechanism 4 passes through above the purification chamber 1. In the design, the fixed installation of the water pumping mechanism 4 and the design of the water inlet pipe 42 enable the water pumping mechanism 4 to efficiently extract the treated water from the purification chamber 1. This layout not only improves the water pumping efficiency but also facilitates operation and maintenance because the position of the water pumping mechanism 4 is convenient for access, and the path design of the water inlet pipe 42 reduces the head loss, ensuring the smooth flow of the water body.

[0034] When the utility model is in use, check all components, including the vacuum water pump 41, the water inlet pipe 42, the drain pipe 43, and the connected sealing cover 31 and discharge cylinder 3, to ensure no leakage or blockage. Then start the water pumping mechanism 4 to make the vacuum water pump 41 start working. Through the operation of the water pumping mechanism 4, the water level in the discharge cylinder 3 can be adjusted, which can ensure the rapid discharge of water. Along with the flow of water, the sewage will pass through the first-stage filtration 11 to the fourth-stage filtration 14 in the purification tank 1, as well as the fifth-stage filtration 34 and the sixth-stage filtration 35 in the discharge cylinder 3, to achieve multiple filtrations and purifications. For the green plants 2 in the first-stage filtration 11 in the purification tank 1, conduct regular maintenance management, including pruning, fertilizing, and pest control, to maintain the healthy growth of the plants and improve their water purification ability. Through the connection of the drain trough 15 and the connecting pipe 36, manage the discharge of the purified water, ensure that the purified water can be discharged smoothly, and at the same time prevent the discharge of untreated or incompletely treated water. Record the operation data of the water pumping mechanism 4 and the water quality monitoring results, analyze the water fluidity and purification effect, and adjust the operation steps and maintenance plan as needed.
