Description

Technical Field

[0001] The present invention relates to the technical field of constructed wetlands, and particularly to a wetland circulation system for garden landscapes. Background Art

[0002] Garden landscape wetlands are complexes composed of artificial substrates, aquatic plants, microorganisms, etc., which are designed and constructed artificially to simulate the structure and function of natural wetlands. They are mainly used for sewage treatment, ecological restoration, etc., and can also be used as part of garden landscapes. Garden landscape wetlands usually include constructed wetlands. Currently, constructed wetland systems are generally divided into horizontal flow, subsurface flow, and vertical flow. Among them, vertical flow constructed wetlands are widely used because they have the advantages of smaller floor area than other forms of wetlands, high treatment efficiency, and the entire system can be completely built underground.

[0003] In the artificial vertical flow wetland of garden landscapes, sewage percolates vertically downward from the surface layer and passes through different filler layers in turn during the downward flow process to achieve the purpose of purification. It has a strong treatment ability for aerobic organic matter in wastewater. However, after the filler layer of the existing vertical flow constructed wetland is used for a period of time, it needs to be replaced. Replacing the filler layer of the existing vertical constructed wetland requires digging up the entire wetland, which is very inconvenient.

[0004] After retrieval, a multi-layer circulating vertical constructed wetland system is disclosed in the publication number: CN106745764B, which includes a wetland base unit, a multi-layer circulating unit, an aquatic plant unit, and an inlet and outlet unit. The wetland base unit includes a reaction tank and an anti-seepage wall laid closely on the inner wall of the reaction tank. In the present invention, the filler layers are vertically connected up and down through three pipes and are connected by second flanges, which can achieve a good mutual sealing effect. Only the corresponding pipes need to be directly taken out for replacing the internal fillers, without the need to dig out the entire wetland system. Comparatively speaking, the effect is better and the replacement is convenient. In the present invention, every three pipes form a circulating pipe after connection, and there are three groups of circulating pipes in each wetland system. Sewage flows in from above any one of the circulating pipes and flows out from above the other two groups of circulating pipes. Under the same floor area, it can achieve a circulating filtration effect, with higher filtration efficiency and effective replacement.

[0005] When replacing the filler layer material in the above application, the pipes need to be taken out. However, since the pipes are buried inside the soil layer, affected by the collapse of the soil when the pipes are taken out, the pipes cannot be inserted back into their original positions during subsequent replacement, making the replacement relatively inconvenient. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a wetland circulation system for garden landscapes to solve the problem of inconvenient replacement of the filler layer.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: A garden landscape wetland circulation system includes a first pool body and a second pool body. The first pool body and the second pool body are cross - distributed. The top of the first pool body is sealed. An installation layer is formed by the downward convexity of the inner top wall of the first pool body. An installation cavity and a liquid inlet cavity are opened on the upper surface of the installation layer. A filtering component is installed inside the installation cavity. The filtering component includes a number of inverted convex - shaped installation channels and a number of circulation ports. The installation channels are opened on the lower surface of the installation cavity. A filter tube is inserted inside the installation channel. A ring - shaped distribution of circulation holes is fixedly arranged on the lower surface of the filter tube. A filler layer is filled inside the filter tube. The circulation ports are opened on the surface of the installation layer for connecting the installation cavity and the liquid inlet cavity. A number of drain pipes are respectively fixedly arranged on the upper side wall of the first pool body. A number of threaded openings corresponding to the filter tubes are opened on the upper surface of the first pool body. A sealing head is threadedly connected inside the threaded opening. A liquid inlet interface is fixedly arranged on the upper surface of the liquid inlet cavity.

[0008] Preferably, a number of first partition layers are fixedly connected to the inner wall of the installation cavity. The top ends of the first partition layers are cross - distributed with the installation channels. The first partition layers divide the inside of the installation cavity into multiple first circulation chambers.

[0009] Preferably, a number of second partition layers are fixedly connected to the inner wall of the first pool body. The inner side walls of the second partition layers are fixedly connected to the outer side wall of the installation layer. The second partition layers are cross - distributed with the installation channels. The second partition layers divide the inside of the first pool body into multiple second circulation chambers. A water quality detector is fixedly arranged at the top end of each second circulation chamber.

[0010] Preferably, a closing component is installed at the circulation port. The closing component includes a receiving groove and a slot. The receiving groove is opened on the lower surface of the circulation port. A sluice gate is slidably connected inside the receiving groove. The slot is opened on the upper surface of the circulation port.

[0011] Preferably, a number of spring telescopic rods are fixedly connected to the bottom end of the sluice gate. The bottom ends of the spring telescopic rods are fixedly installed on the inner bottom wall of the receiving groove. An extrusion plate is fixedly connected to the upper side wall of the sluice gate.

[0012] Preferably, a purification component is installed inside the second pool body. The purification component includes a number of planting boxes. The two ends of the planting boxes are slidably connected to the inner wall of the second pool body. A soil layer is filled inside the inner wall of the planting boxes. A matrix - distributed water - permeable hole is opened on the lower surface of the planting boxes. The soil layer is used for planting water plants.

[0013] Preferably, the purification component further includes a number of support layers. The outer walls of the support layers are fixedly connected to the inner wall of the second pool body. A number of support columns are fixedly arranged on the inner wall of the second pool body. The support columns are vertically distributed with the support layers. The support columns penetrate through the planting boxes.

[0014] Preferably, the support layer is used to divide several purification chambers under the second pool body. An activated carbon filter layer is filled inside the purification chambers, and several drain ports are respectively arranged on the lower sides of the second pool body and the support layer.

[0015] Preferably, an inclined block one is fixedly arranged above the planting box, and the inclined block one is fixedly arranged on the upper surface of the outermost planting box.

[0016] Preferably, the upper surfaces of both sides of the second pool body are respectively rotationally connected with cover plates through shafts, and several inclined blocks two are fixedly connected to one end of each cover plate.

[0017] Working principle: Connect the liquid inlet interface to the high-pressure pump through a pipeline. Input the sewage in the garden into the interior of the liquid inlet chamber through the high-pressure pump. The sewage enters the installation chamber through the flow port, is filtered through the filler layer in the filter pipe, then flows out through the installation channel, and is then introduced into the second pool body through the drain pipe. The filler layer plays a role in circulating filtration. Since a filler layer is separately arranged in each filter pipe, when replacing the filler layer, the sealing head can be unscrewed to open the threaded opening, and then the filter pipe can be quickly taken out to replace the filler layer inside it, without having to dig out the entire wetland system. By separating the filter pipe from the soil layer, the replacement of the filler layer is not affected by the soil layer, and the replacement is simpler and more convenient.

[0018] After the sealing head is screwed and installed, it will press down the pressing plate, pushing the gate plate to slide down into the storage groove to automatically open the flow port for the sewage to flow. When opening the sealing head to replace the filler layer, the pressure on the pressing plate disappears, and the gate plate gradually slides upward through the elastic force of the spring telescopic rod until it inserts into the interior of the slot, thus automatically blocking the flow port. Furthermore, when replacing the filter pipe, the flow port can be blocked, preventing the sewage from flowing through the flow chamber one where the filter pipe is located, thus avoiding the problem of unfiltered sewage flowing out and realizing replacement without stopping the machine.

[0019] Each filter pipe is separated by the first partition layer and the second partition layer, enabling multiple nitrogen and phosphorus sensors to respectively classify and monitor the sewage filtered by multiple groups of filler layers. Thus, when the phosphorus value of the sewage filtered by the nitrogen and phosphorus sensor corresponding to a single filter pipe exceeds the threshold, the staff can separately replace the filter pipe according to the prompt of the warning device, so as to enable the staff to replace the filler layer in a timely manner.

[0020] The drainage pipe discharges the filtered sewage into the interior of the planting box. Aquatic plants are planted in the soil layer, which has the effect of further improving the water quality. At the same time, aquatic plants can enrich the garden landscape. The water inside the planting box flows underwater into the purification chamber and is further filtered and purified through the activated carbon filter layer to achieve multiple purification effects, which can further digest the nitrogen and phosphorus content. The water filtered by the activated carbon filter layer is collected at the bottom of the pool body 2 and flows out of the pool body from the drainage port to realize water circulation. When the activated carbon filter layer in a purification chamber needs to be replaced, the cover is rotated to open, and then the planting box is pushed to be staggered with the purification chamber, so as to open the purification chamber for convenient replacement of the activated carbon filter layer in the purification chamber without turning over the soil layer, which is convenient for the maintenance and replacement of the activated carbon filter layer.

[0021] The present invention provides a garden landscape wetland circulation system, which has the following beneficial effects:

[0022] 1. The present invention sets a packing layer separately in the filter tube. When replacing the packing layer, the filter tube is taken out to replace the packing layer inside it without digging out the entire wetland system. The filter tube is separated from the soil layer, so that the replacement of the packing layer is not affected by the soil layer, and the replacement is simpler and more convenient.

[0023] 2. During filtration, the sealing head of the present invention presses down the gate plate to realize automatic opening of the flow port to allow sewage to flow. When the sealing head is opened to replace the packing layer, the gate plate automatically blocks the flow port to prevent unfiltered sewage from flowing out, thereby realizing replacement without stopping the machine.

[0024] 3. The present invention supports the planting box in the air by cooperating between the supporting layer and the supporting column, so that the gravity of the planting box does not act on the activated carbon filter layer, thereby preventing the pores of the activated carbon filter layer from being excessively squeezed and affecting the flow of water.

[0025] 4. When replacing the activated carbon filter layer of the present invention, the planting box is pushed to be offset from the purification chamber that needs to be replaced, thereby opening the purification chamber without turning over the soil layer, thereby facilitating the maintenance and replacement of the activated carbon filter layer.

Detailed implementation manners

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a garden landscape wetland circulation system, which includes a first pond 1 and a second pond 2. The first pond 1 and the second pond 2 are cross-distributed, the top of the first pond 1 is sealed, and a mounting layer 3 is formed by the downward convexity of the inner top wall of the first pond 1. An installation cavity 4 and a liquid inlet cavity 5 are provided on the upper surface of the mounting layer 3. A filtering component 6 is installed inside the installation cavity 4. The filtering component 6 includes a number of inverted convex installation channels 61 and a number of circulation ports 64. The installation channels 61 are opened on the lower surface of the installation cavity 4. A filter tube 62 is inserted into the interior of the installation channel 61. A ring-shaped distribution of circulation holes is fixedly arranged on the lower surface of the filter tube 62. A filler layer 63 is filled inside the filter tube 62. The circulation ports 64 are opened on the surface of the mounting layer 3 for connecting the installation cavity 4 and the liquid inlet cavity 5. A number of drain pipes 7 are respectively fixedly arranged on the upper side wall of the first pond 1. A number of threaded openings 8 corresponding to the filter tubes 62 are opened on the upper surface of the first pond 1. A sealing head 10 is threadedly connected inside the threaded opening 8. A liquid inlet interface 11 is fixedly arranged on the upper surface of the liquid inlet cavity 5. The filler layer 63 includes four layers from top to bottom, namely a 50mm cobblestone layer, a 20mm gravel layer, a 5mm gravel layer, and a 1mm fine sand layer. The diameter of the circulation holes is less than 1mm to prevent the fine sand layer from falling. An accommodation groove 651 is formed by the upward convexity of the lower surface of the sealing joint. The top end of the filter tube 62 is inserted into the interior of the accommodation groove 651. Openings are respectively provided on both sides of the filter tube 62 for allowing sewage to enter the filter tube 62 and facilitating personnel to hook the openings with tools to take out the filter tube 62.

[0037] Specifically, the mounting layer 3 is used to support the filter tube 62, and the liquid inlet interface 11 is used to input sewage. The sewage first enters the liquid inlet cavity 5 through the liquid inlet interface 11, then enters the installation cavity 4 through the circulation port 64, and flows out of the mounting layer 3 through the installation channel 61. The filter tube 62 is used to accommodate the filler layer 63, and the filler layer 63 is used to filter the sewage. The filtered sewage flows out of the filter tube 62 through the circulation holes. The sealing head 10 is used to block the threaded opening 8 to prevent the sewage from flowing out. The sewage enters the installation cavity 4 through the circulation port 64, is filtered by the filler layer 63 in the filter tube 62, then flows out through the circulation holes, and is then introduced into the second pond 2 through the drain pipe 7, achieving the effect of circulating filtration through the filler layer 63. Since a separate filler layer 63 is provided inside each filter tube 62, when replacing the filler layer 63, the sealing head 10 can be unscrewed to open the threaded opening 8, and the filter tube 62 can be quickly taken out to replace the filler layer 63 inside it, without having to dig out the entire wetland system. Moreover, compared with the prior art, the filter tube 62 is separated from the soil layer 92, and the replacement is not affected by the soil layer 92, making the replacement of the filler layer 63 simpler and more convenient.

[0038] Please refer to the attached Figure 3 - attached Figure 4, a plurality of first partition layers 12 are fixedly connected to the inner wall of the installation cavity 4. The top ends of the first partition layers 12 are cross-distributed with the installation channels 61. The first partition layers 12 divide the interior of the installation cavity 4 into multiple first flow chambers. A plurality of second partition layers 13 are fixedly connected to the inner wall of the first pool body 1. The inner side walls of the second partition layers 13 are fixedly connected to the outer side walls of the installation layer 3. The second partition layers 13 are cross-distributed with the installation channels 61. The second partition layers 13 divide the interior of the first pool body 1 into multiple second flow chambers. A water quality detector 14 is fixedly arranged at the top end of each second flow chamber. The water quality detector 14 uses a nitrogen-phosphorus sensor. The water quality detector 14 is electrically connected to a controller, and the controller is electrically connected to a plurality of warning devices. Each warning device is respectively connected to a nitrogen-phosphorus sensor, and the warning device gives a warning according to the detection data of the corresponding nitrogen-phosphorus sensor.

[0039] Specifically, the drain pipe 7 is cross-distributed with the second partition layer 13. The water discharged from the drain pipe 7 is monitored by the water quality detector 14. When the nitrogen-phosphorus sensor detects that the nitrogen-phosphorus value exceeds the threshold, a warning is given through the warning device to remind the staff to replace the packing layer 63 in time. Through the cooperation of the first partition layer 12 and the second partition layer 13, each filter pipe 62 can be separated, so that the sewage filtered by a single filter pipe 62 does not contact the sewage filtered by the adjacent filter pipe 62. Therefore, when the phosphorus value of the filtered sewage detected by the nitrogen-phosphorus sensor corresponding to a single filter pipe 62 exceeds the threshold, the staff can replace the filter pipe 62 alone according to the prompt of the warning device, which is convenient for precise operation.

[0040] Please refer to the appendix Figure 5 , a closing assembly 65 is installed at the through port 64. The closing assembly 65 includes a receiving groove 651 and a slot 655. The receiving groove 651 is opened on the lower surface of the through port 64. A sluice gate 652 is slidably connected inside the receiving groove 651. The slot 655 is opened on the upper surface of the through port 64. The slot 655 is opened on one side of the installation cavity 4. A plurality of spring telescopic rods 653 are fixedly connected to the bottom end of the sluice gate 652. The bottom ends of the spring telescopic rods 653 are fixedly installed on the inner bottom wall of the receiving groove 651. An extrusion plate 654 is fixedly connected to the upper side wall of the sluice gate 652. Sealing layers made of sealing materials are fixedly arranged on the inner walls of the through port 64, the slot 655 and the receiving groove 651. The sealing materials can be selected such as rubber, polytetrafluoroethylene, etc. The designed shape of the sluice gate 652 is precisely matched with the receiving groove 651, the slot 655 and the through port 64 to ensure the fitting degree between the two, reduce the gap, and thus improve the closing effect of the sluice gate 652 and the through port 64.

[0041] Specifically, the slot 655 is L-shaped for insertion when the gate plate 652 and the extrusion plate 654 move upward. The first separation layer 12 divides the interior of the installation cavity 4 into multiple first flow chambers. The liquid inlet cavity 5 is connected to multiple first flow chambers through multiple flow ports 64. When the sealing head 10 is screwed down, it abuts against the extrusion plate 654, thereby pushing the gate plate 652 to slide down into the storage groove 651, realizing the automatic opening of the flow port 64 for sewage to flow. When the sealing head 10 is rotated upward, the gate plate 652 gradually slides upward through the elastic force of the spring telescopic rod 653 until it is inserted into the interior of the slot 655, thereby automatically blocking the flow port 64. Furthermore, when replacing the filter tube 62, the flow port 64 can be blocked, so that sewage does not flow through the first flow chamber where the filter tube 62 is located, thus avoiding the problem of unfiltered sewage flowing out and realizing replacement without stopping the machine.

[0042] Please refer to the attached Figure 6 - attached Figure 8 , a purification component 9 is installed inside the second pool body 2. The purification component 9 includes several planting boxes 91. Both ends of the planting box 91 are slidably connected to the inner wall of the second pool body 2. The inner wall of the planting box 91 is filled with a soil layer 92. The lower surface of the planting box 91 is provided with water permeable holes 93 distributed in a matrix. The soil layer 92 is used for planting aquatic plants. The number of drain pipes 7 on one side of the first pool body 1 is the same as the number of planting boxes 91. The aquatic plants are emergent plants, and the emergent plants are a combination of lotus, dwarf lotus, reed, cattail, wild rice stem and tabernaemontanus bulrush. Comprehensive planting can play a better role in treating nitrogen and phosphorus.

[0043] Specifically, the water permeable holes 93 are used for the water at the bottom of the planting box 91 to flow out. The drain pipe 7 extends above the planting box 91 to discharge the filtered sewage into the interior of the planting box 91. Planting aquatic plants in the soil layer 92 has the effect of further improving the water quality, and at the same time, the aquatic plants can enrich the garden landscape.

[0044] Please refer to the attached Figure 7 - attached Figure 8 , the purification component 9 further includes several support layers 94. The outer wall of the support layer 94 is fixedly connected to the inner wall of the second pool body 2. Several support columns 16 are fixedly arranged on the inner wall of the second pool body 2. The support columns 16 are vertically distributed with the support layer 94, and the support columns 16 penetrate through the planting box 91.

[0045] Specifically, the support layer 94 is used for horizontally supporting the planting box 91, and the support column 16 is used for vertically supporting the planting box 91, thereby dispersing and bearing the gravity of the planting box 91, so that the gravity of the planting box 91 does not act on the activated carbon filter layer 95, avoiding excessive extrusion of the pores of the activated carbon filter layer 95 and affecting the flow of water.

[0046] Please refer to the attached Figure 7The support layer 94 is used to divide the bottom of the pool body 2 into a plurality of purification chambers. The interior of the purification chamber is filled with an activated carbon filter layer 95. A plurality of drainage ports 17 are respectively provided on the lower sides of the pool body 2 and the support layer 94. The activated carbon structure is stable and hard, and it is not easy to produce debris to block the drainage port 17.

[0047] Specifically, the water inside the planting box 91 flows down to the purification chamber and is further filtered and purified by the activated carbon filter layer 95 to achieve multiple purification effects, which can further digest the nitrogen and phosphorus content. The water filtered by the activated carbon filter layer 95 is collected at the bottom of the pool body 2 and flows out of the pool body through the drain port 17 to realize water circulation. When it is necessary to replace the activated carbon filter layer 95 in a purification chamber, the planting box 91 is pushed to be offset from the purification chamber, thereby opening the purification chamber to facilitate the replacement of the activated carbon filter layer 95 in the purification chamber without turning over the soil layer 92, thereby facilitating the maintenance and replacement of the activated carbon filter layer 95.

[0048] Please see attached Figure 6 A slanted block 19 is fixedly arranged above the planting box 91, and the slanted block 19 is fixedly arranged on the upper surface of the outermost planting box 91. The upper surfaces of both sides of the pool body 2 are respectively connected with cover plates 20 through shaft rotation. One end of the cover plate 20 is fixedly connected with a plurality of slanted blocks 21. The cover plate 20 is fastened to the upper surface of the pool body 2 2 in a threaded connection manner through bolts.

[0049] Specifically, by covering the cover 20 on the pool body and fixing it with bolts, the inclined block 21 is rotated to press against the inclined block 19, thereby fixing the planting box 91 to prevent the planting box 91 from sliding during use and preventing external garbage from falling into the interior of the pool body 2. After the cover 20 is rotated open, the planting box 91 can be slid and the activated carbon filter layer 95 can be replaced.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
