Description

Technical field

[0001] The present invention relates to the technical field of aquatic ecological remediation, in particular a modular ecological floating island with a plant-microbe combination. State of the art

[0002] The ecological floating island is based on aquatic plants, utilizes the principle of soilless cultivation, employs polymeric materials as carriers and substrates, and fully exploits the space and ecological nutrient niche of the water body through the symbiotic relationship between different species to create an efficient artificial ecosystem and thus effectively reduce the water's pollution load. The system is capable of breaking down pollutants such as chemical oxygen demand (COD), nitrogen, and phosphorus in the water by employing the principles of ecological engineering for eutrophic water quality. This not only significantly improves the water's clarity but also effectively enhances water quality indicators, particularly by significantly inhibiting algae growth.The main role of ecological floating islands in water purification is to utilize the plant root system to absorb eutrophying substances in the water, such as total phosphorus, ammonium nitrogen and organic matter, to transfer nutrients in the water body and to alleviate the fishy odor and eutrophication caused by the closure or insufficient self-circulation of the water body.

[0003] However, existing traditional floating ecological islands mostly have a fixed structure, which presents the following main problems: they are cumbersome to transport and install, have a large overall volume, and are difficult to adapt to the shape of complex bodies of water; they rely solely on plants to absorb pollutants and have a limited purification effect; they incur high maintenance costs and must be completely replaced after damage, resulting in a lack of flexibility; and they are not stable enough, so fluctuations in the water level can easily cause the floating island to capsize or sink. Therefore, the question of how to develop a floating ecological island capable of overcoming the above problems has become a key challenge to be addressed.

[0004] It goes without saying that the foregoing explanations only represent the technical background for the present invention and do not necessarily belong to the prior art. Content of the invention

[0005] Based on the above technical problems, one purpose of the present invention is to provide a modular ecological floating island with a plant-microbe combination that significantly improves the purification capacity of a body of water while simultaneously simplifying installation and maintenance.

[0006] To achieve the above purpose, the present invention provides a modular ecological floating island with a plant-microbe combination, comprising: a floating shell body provided with a cavity extending through a thickness direction of the floating shell body; a planting trough having a tubular structure with an open top and a closed bottom, and detachably arranged within the cavity, the bottom of the planting trough being lower than the lower surface of the floating shell body; a filter screen mounted horizontally within the planting trough, dividing the planting trough into an upper planting area and a lower bioreaction area.

[0007] Aquatic plants are planted in the planting area. The floating bowl body is equipped with a tenon connection structure on one side, whereby the adjacent floating bowl bodies are joined horizontally and vertically by the tenon connection structure.

[0008] Preferably, a planting substrate is arranged within the planting area, while a biological filling material is arranged within the bioreaction area.

[0009] Preferably, the hole diameter of the filter sieve is smaller than the outer diameter of the planting substrate.

[0010] Preferably, the biological filling material is arranged in a mesh bag, wherein the hole diameter of the mesh bag is smaller than the particle size of the biological filling material.

[0011] Preferably, the floating shell body has a hollow structure and is filled inside with a filler material whose density is less than that of the floating shell body.

[0012] Preferably, the floating shell body has a polygonal structure and is provided on each side alternately with a protruding pin and a recessed mortises, wherein the adjacent floating shell bodies are connected to each other by the protruding pin and the recessed mortises to form an interference fit.

[0013] Preferably, the floating shell body is provided on an upper surface with an anchor chain connecting ring to connect a ship's anchor or an underwater counterweight block in order to adaptively raise and lower the ecological floating island.

[0014] Preferably, a plurality of axially extending water-permeable channel seams are arranged spaced apart from one another on a side wall of the planting channel.

[0015] Preferably, the water-permeable gutter seams are spiral-shaped.

[0016] Preferably, the root system of the aquatic plant passes through the filter screen and extends into the bioreaction area to come into contact with the biological filling material, and the root system is free to grow to an outside of the water-permeable channel seams to come into contact with the water outside the water-permeable channel seams.

[0022] Unless otherwise defined, all technical and scientific terms used in the description of this application have the same meaning as they are generally understood by those skilled in the art in the field of the present application. Terms used in the description of this application serve only to describe certain embodiments and are not intended to limit the present application. The term "and / or," as used in the description of this application, includes all combinations of one or more of the relevant points listed.

[0023] As in the Fig. As shown in Figure 1, the present invention provides a modular ecological floating island with a plant-microbe combination, comprising: a floating shell body 1, which is provided with a cavity extending through a thickness direction of the floating shell body; a planting trough 2, which has a tubular structure with an open top and a closed bottom and is detachably arranged within the cavity of the floating shell body 1, wherein the bottom of the planting trough 2 is lower than the lower surface of the floating shell body 1; a filter screen 3, which is attached horizontally within the planting trough 2 and divides the planting trough 2 into an upper planting area and a lower bioreaction area.

[0024] Furthermore, a planting substrate is arranged within the planting area, i.e., the planting substrate is located above the filter screen 3 for planting the aquatic plants; within the bioreaction area, a biological filling material 4 is arranged for the degradation of organic substances in the water.

[0025] Furthermore, in the preferred embodiment of the present invention, the planting substrate is a ceramic planting substrate, and the hole diameter of the filter sieve 3 is smaller than the outer diameter of the planting substrate, thereby preventing a loss of the planting substrate.

[0026] Furthermore, the filter screen 3 in the present invention is made of stainless steel.

[0027] Furthermore, the filter screen 3 in the present invention also traps suspended solids in the water and prevents impurities from the planting area from entering the bioreaction area and causing a blockage of the biological filling material 4.

[0028] Furthermore, the root system of the aquatic plant can pass through the filter screen 3 and extend into the bioreaction area to come into contact with the biological filling material 4, creating a synergistic effect for nitrogen and phosphorus removal with microorganisms.

[0029] Furthermore, the biological filling material 4 is arranged in a net bag, and the hole diameter of the net bag is smaller than the particle size of the biological filling material, so that no leakage of the biological filling material 4 can occur and at the same time the organic substances in the water can penetrate through the hole of the net bag to the surface of the biological filling material 4 in order to be broken down by the adhering microorganisms.

[0030] Furthermore, in the present invention, the biological filling material 4 consists of porous ceramic grains or polyurethane fibers.

[0031] Furthermore, the floating shell body 1 has a hollow structure and is filled inside with a light filler whose density is less than that of the floating shell body 1, which effectively improves the compressive strength and stability of the floating shell body 1.

[0032] Furthermore, in the present invention, the floating shell body 1 is made of high-density polyethylene, and the material of the lightweight filler is polystyrene foam.

[0033] Furthermore, a large number of axially extending water-permeable channel seams are arranged spaced apart from one another on a side wall of the planting channel 2.

[0034] Furthermore, the water-permeable channel seams are spiral-shaped, which can effectively improve the exchange of substances between a body of water, the biological fill material 4 and the plant roots; and the water-permeable channel seams allow the root system of the aquatic plants to grow freely to the outside of the water-permeable channel seams in order to come into contact with the water outside the water-permeable channel seams and to enhance the absorption capacity of the nitrogen and phosphorus elements in the water.

[0035] Furthermore, in the present invention, the aquatic plant is an iris or a reed.

[0036] As in the Fig. As shown in Figure 2, the floating shell body 1 has a polygonal structure (the number of sides is 2n, where n is a natural number greater than or equal to 2). The floating shell body 1 is further provided on its side with a standardized tenon connection structure, and the floating shell body 1 is provided on each side alternately with a projecting tenon 11 and a recessed mortise 12, which enables a multidirectional connection in a horizontal and a vertical direction. In a preferred embodiment of the present invention, the floating shell body 1 has a hexagonal structure, and the tenons 11 and mortise 12 are arranged alternately on six side edges of the hexagon, with three tenons and three mortise 12 being provided.

[0037] The pin 11 has a trapezoidal, projecting cut, and the mortises 12 are provided with a corresponding trapezoidal mortises, and the two form an interference fit so that two adjacent floating shell bodies 1 can be connected to each other (as in the Fig. 1 shown).

[0038] Furthermore, the floating shell body 1 is provided at a point on the upper surface of the two adjacent sides with an anchor chain connecting ring 13, which, depending on the application scenario, can be connected via an elastic rope to a ship's anchor 14 or an underwater counterweight block 15, enabling the adaptive raising and lowering of the ecological floating island in case of fluctuating water levels.

[0039] As an example, consider an application in a wetland:

[0040] The assembly of the present invention proceeds in particular as follows: First, a plurality of floating shell bodies 1 are brought into the desired shape by means of a standardized pin connection structure to form an ecological floating island; Second, a planting trough 2 is inserted into the cavity of each floating shell body 1, and the planting substrate is filled into the upper planting area of ​​the planting trough 2 and aquatic organisms are planted, and a biological filling material 4 is introduced into the lower bioreaction area of ​​the planting trough 2; Finally, the installation is completed by securing the ecological floating island in the water body with the aid of the anchor chain connecting ring 13.

[0041] It should be noted that the cleaning efficiency of the ecological floating island for the water body can be improved by regularly removing the filter screen 3 or regularly replacing the aged biological filling material 4 or by supplementing the aquatic plant stock.

[0042] In summary, the present invention provides a modular ecological floating island with a plant-microbe combination that, through its modular composition, is able to adapt to the shape of various bodies of water, thus facilitating transport, local replacement, and expansion. Simultaneously, the ecological floating island provided by the present invention combines a multi-stage synergistic purification technology, physically trapping suspended solids in the water through a filter screen and utilizing the synergistic action of plants and microorganisms to effectively absorb nutrient-rich elements in the water and degrade organic matter, thereby significantly improving the purification efficiency for the water body. Furthermore, the ecological floating island also employs an anchoring structure to prevent it from shifting in the water, effectively extending its lifespan.

[0043] Although the present invention has been described in detail with reference to the preferred embodiments above, the foregoing description is not to be understood as limiting the present invention. Various modifications and alternatives to the present invention will be obvious to the person skilled in the art after reading the foregoing. Therefore, the scope of protection of the present invention should be limited by the accompanying claims.
