Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water ecological restoration and treatment, and particularly relates to a combined floating wetland. BACKGROUND

[0002] In the process of recovering the ecological environment of rivers and lakes, using reclaimed water as a water supplement is a common method in actual restoration and treatment, which helps to reduce the demand for fresh water, reduce the cost and environmental impact of sewage treatment. However, compared with fresh water, the water quality of the slow-moving water body after the use of reclaimed water may deteriorate, which is not conducive to achieving the goal of ecological environment restoration of rivers and lakes. Therefore, technical measures need to be taken in source control, process reduction and end treatment to ensure the achievement of the goal of ecological environment restoration of rivers and lakes.

[0003] In the related art, floating wetlands can directly act on the water body, remove pollutants from the water body, and achieve ecological restoration. Therefore, floating wetlands can be used to achieve end treatment in the above-mentioned problem of deterioration of the water quality of slow-moving water bodies. The working principle of the floating wetland is similar to that of the subsurface wetland, which integrates the decomposition of the filler (carrier) microorganism and the absorption of the plant to achieve long-term ecological effect.

[0004] In the actual implementation process of the treatment project, the inventor found that in the construction and implementation of the existing floating wetland product, the bulk carrier material is cut on site, and the cut material is directly spliced by using a rope to pass through the space. Based on this, the actual application floating wetland is obtained, such as the floating wetland involved in the prior art patent CN211394026U "Floating wetland with porous carrier structure". Although this method can flexibly meet the needs of various specific scenes, it has too many on-site operations, which affects the efficiency of project implementation. In addition, due to the different cutting methods, the overall stability of the floating wetland obtained after splicing the carrier cannot be guaranteed, and problems such as disintegration and overturning may occur during subsequent use in large-scale engineering applications.

[0030] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0031] As described in the background, in the recovery of river and lake ecological environment, using reclaimed water as a water supplement is a common method in actual restoration and management, which helps to reduce the demand for fresh water sources, reduce the cost and environmental impact of wastewater treatment. However, compared with fresh water, the water quality of the slow-moving water body after the use of reclaimed water may deteriorate, which is not conducive to achieving the goal of ecological environment restoration of rivers and lakes, and technical solutions need to be developed in terms of source control, process reduction and end-of-pipe treatment to ensure the achievement of the goal of ecological environment restoration of rivers and lakes.

[0032] In the related art, floating wetlands can directly act on the water body, remove pollutants from the water body, and achieve ecological restoration, so floating wetlands can be used to achieve end-of-pipe treatment in the above-mentioned slow-moving water body water quality deterioration problem. The working principle of floating wetlands is similar to that of subsurface wetlands, which integrates the combined action of filler (carrier) microbial decomposition and plant absorption to achieve long-term ecological effects.

[0033] In the actual implementation process of the treatment project, the inventors found that in the construction and implementation of existing floating wetland products, bulk carrier materials are cut on site, and the cut materials are directly spliced with ropes in a way of passing through the void. Based on this, the actual application floating wetland is obtained, such as the floating wetland involved in the prior art patent CN211394026U "Floating wetland with porous carrier structure". Although this method can flexibly meet the needs of various specific scenarios, it involves too much on-site work, affecting the efficiency of project implementation, and since the cutting methods are different, the overall stability of the floating wetland obtained after splicing the carrier cannot be guaranteed, and problems such as disintegration and overturning may occur during subsequent use in large-scale engineering applications.

[0034] In view of this, the application provides a combined floating wetland to help improve the construction efficiency in actual projects.

[0035] As Figures 1 to 3 shown, in an embodiment, the combined floating wetland provided by the application, similar to the prior art, also includes the planting soil layer 100 and the carrier layer 200 arranged oppositely, but the carrier layer 200 in the technical solution of the application is connected and combined by a plurality of carrier units 210, as Figure 2 shown, which is a connection and combination diagram of two carrier units 210.

[0036] As Figure 2 and Figure 3 shown, the carrier unit 210 includes a unit frame 211 in the shape of a regular hexagon, the carrier material 212 is arranged in the unit frame 211, and a special-shaped groove 211a matched with the connecting piece 300 is vertically arranged on the outer surface of each side of the unit frame, and each adjacent two carrier units 210 are connected and combined through the connecting piece 300 matched with the special-shaped groove 211a.

[0037] As Figure 1 shown, the carrier unit constituting the edge of the carrier layer is also connected with a fixing piece 400, and the carrier layer 200 is connected with the positioning body 500 in the water through the fixing piece 400. For example, similar to the prior art, the fixing piece here can be a stainless steel rope or a chain ring, and the positioning body can be a pile body on the water bottom, which is fixed on the water bottom in the form of piling, and it is easy to understand that the length of the fixing piece and the installation point and weight of the positioning body can be determined according to the actual terrain, water depth, water level change and other situation information.

[0038] It should be noted that Figure 1 the center line A represents the water surface, the line B represents the water bottom, and C represents the aquatic plants.

[0039] In the technical solution of the application, the carrier layer of the floating wetland is connected and composed of a plurality of standardized carrier units, compared with the on-site cutting and rope space assembly mode in the prior art, this form of floating wetland is beneficial to improve the implementation efficiency of the project; and each carrier unit has a unit frame structure in the shape of a regular hexagon, and the connection and composition of the carrier layer is realized through the special-shaped groove on the frame and the connecting piece matched with the special-shaped groove, so that the connected carrier layer as a whole is similar to a honeycomb structure, which is beneficial to improve the overall stability of the floating wetland.

[0040] The defects of the above scheme are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the application to solve the above problems in the following should be the contribution of the inventors to the application in the process of the application

[0041] For the convenience of understanding the technical solutions of the present application, the technical solutions of the present application are introduced and described below by means of some other embodiments.

[0042] In some embodiments, as shown in Figures 1 to 3 The combined floating wetland proposed by the present application comprises a planting soil layer 100 and a carrier layer 200 arranged oppositely, and the carrier layer 200 is connected and combined by a plurality of carrier units 210.

[0043] As shown in Figure 2 and Figure 3 The carrier unit 210 comprises a regular hexagonal unit frame 211, and a carrier material 212 is arranged in the unit frame 211. An irregular groove 211a matched with the connecting piece 300 is vertically arranged on the outer surface of each side of the unit frame. The adjacent two carrier units 210 are connected and combined by the connecting piece 300 matched with the irregular groove 211a.

[0044] Similarly, as shown in Figure 1 In this embodiment, the carrier unit forming the edge of the carrier layer is further connected with a fixing piece 400, and the carrier layer 200 is connected with the positioning body 500 in water through the fixing piece 400.

[0045] As for the irregular groove and the connecting piece, specifically, in these embodiments, as shown in Figures 2 to 4 The irregular groove 211a is a dovetail groove, and when the two carrier units are connected and combined, the corresponding two dovetail grooves on the two side edges form a double-dovetail hole (as shown in Figure 2 The connecting piece 300 is a double-dovetail plug matched with the hole. In this way, the connecting piece is connected with the irregular groove similar to the traditional mortise and tenon structure, which is conducive to the rapid implementation of the connection and combination.

[0046] In actual implementation, the size of the double-dovetail plug can be slightly larger than the hole based on the control of the specific size, so as to improve the fastening of the connection by means of interference fit.

[0047] Further, for the convenience of operation and construction in practice, as shown in Figure 4 One end of the double-dovetail plug (connecting piece 300) forms a column cap structure 310 for facilitating the connection operation. In this way, in the construction operation, the plug can be inserted by knocking the column cap end.

[0048] In addition, in some specific embodiments, in order to realize convenient disassembly, the interference fit mode can not be used, but as shown in Figure 4As shown, on the basis of the setting of the post cap structure 310, the length of the insertion part of the double dovetail insertion block is configured to be slightly greater than the depth of the hole, and a horizontal through hole 320 is formed on the other end of the double dovetail insertion block, which can be used for inserting a split pin, that is, in a combined application, the insertion block is inserted into the hole, and the horizontal through hole on the other end of the insertion block is exposed, at which time the split pin is inserted, so that under the combined limiting action of the split pin and the post cap structure, the insertion block will not fall out of the hole, thereby realizing the connection and combination of different carrier units; when disassembly is required, the split pin is removed or cut, and the insertion block can be conveniently removed, thereby realizing the separation of the combined carrier units.

[0049] In some embodiments, in order to ensure the stability of the connection of different carrier units and considering the flexibility of practical application, as shown in Figure 2 and Figure 3 As shown, the special-shaped grooves 211a on each side edge of the unit frame 211 are two, and the two special-shaped grooves on each side edge are respectively arranged at the three equal parts of the side edge;

[0050] Further, in some embodiments, in order to enhance the purification ability of the water body, as shown in Figure 5 The combined floating wetland also includes an ecological base floating belt 600 arranged in the water, one end of the ecological base floating belt 600 is tied in the horizontal through hole of the insertion block through a connecting rope (it is easy to understand that the split pin cannot occupy the through hole, and the connecting rope can be tied in the remaining gap), and the other end is sunk to the bottom of the water through a counterweight bag;

[0051] As a person skilled in the art would easily understand, the ecological base floating belt belongs to a bionic water plant, which has the characteristics of high specific surface area, so that the contact area of microorganisms is increased, and as a microbial carrier, it promotes the growth and proliferation of microorganisms, forms a biofilm, and promotes the absorption and decomposition of nutrient salts and organic matter in the water by microorganisms in the water in a contact oxidation manner, thereby degrading pollutants and strengthening the self-purification ability of the water body.

[0052] In these embodiments, the unit frame can be made of HDPE (high-density polyethylene), which is a high-molecular polymer with good rigidity and toughness, high mechanical strength, good resistance to environmental stress cracking and tearing strength, and small specific gravity, which can better meet the performance requirements of floating wetland applications.

[0053] Similar to the prior art, in the above embodiments, the carrier material of the carrier unit can also be a composite fiber material.

[0054] For example, the composite fiber material herein includes a first carrier layer and a second carrier layer arranged oppositely, and the two layers are fixedly connected, the first carrier layer is made of plant fiber material, for example, the first carrier layer is a palm mat or a coconut mat, which is made of long fibers of palm trees or coconut trees; the second carrier layer is made of polyester fiber or polyurethane fiber material, for example, the second carrier layer is a foamed sponge made of polyurethane, or the second carrier layer is made of PBT, and the advantages of polyester fiber are high hardness, wear resistance, high compression resistance and large bearing capacity; or, the second carrier layer is PTT, and PTT has hydrophilicity and strong water absorption performance, which can provide water for the growth of wetland plants; a glue layer is arranged between the second carrier layer and the first carrier layer, the glue layer is an environmentally friendly glue (AB glue), or the second carrier layer and the first carrier layer are fixedly connected through rivets, and the specific technical details of this part can be found in existing public technical materials, which will not be described here in detail.

[0055] Similar to the prior art, in some embodiments, as shown in Figure 1 and Figure 2 , a plurality of planting holes 212a for planting aquatic plants are vertically arranged on the carrier material 212 of each carrier unit 210, and it should be noted that Figure 2 the size, number and distribution of the planting holes 212a in are only a demonstration, and the size, number and distribution of the planting holes can be flexibly selected and set based on the scene requirements, and the present application does not limit this;

[0056] The planting soil layer 100 is nutrient soil, light-weight ceramic particles or glass lightweight stones, and the planting soil layer covers the carrier material and the planting holes, and in some specific implementation scenarios, the aquatic plants mentioned herein are one or more of yellow flag iris, canna, and Lythrum salicaria.

[0057] Based on the above embodiments, in some embodiments, the carrier layer 200 is in the shape of a ring with a hollow in the middle; as shown in Figure 5 , the combined floating wetland further includes an aeration device 700 arranged in the hollow, for example, the aeration device 700 herein is a fountain aerator, which is clamped on the unit frame of the carrier unit around the hollow through a mounting bracket, and the fountain aerator works to increase the dissolved oxygen content and speed up the water flow, which is beneficial to quickly decompose nitrogen and phosphorus organic pollutants, improve water quality, and improve the self-cleaning capacity of the water body.

[0058] In addition, it should be noted that, due to the application scenario of the present application, similar to the prior art, the power supply of the aeration device herein can also be achieved by arranging solar photovoltaic modules, and the arrangement of the solar photovoltaic modules can be selected and arranged based on the actual scene characteristics, which will not be described here in detail.

[0059] In the actual governance engineering implementation process, the inventors also found that the water quality of the reclaimed water may be different in different areas and time periods, and targeted water quality monitoring is needed to evaluate the purification effect of the floating wetland. Therefore, based on the above embodiments, similar to the setting of the aeration device, the connection and combination mode of the carrier units can be adjusted during the construction of the carrier layer to form corresponding gaps on the carrier layer. The water quality monitoring instruments and data transmitters can be installed and arranged through the corresponding mounting racks in the gaps to monitor the water quality of the water area where the wetland is located, obtain the corresponding monitoring data, and provide strong data support for the implementation and application of the governance project.

[0060] The above describes only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application.
