Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of submerged plant planting, and in particular to a water-purifying submerged plant degradable planting carrier and a planting method. Background Art
[0002] The current mainstream water purification technologies are mainly divided into physical methods (such as filtration, sedimentation, aeration), chemical methods (such as flocculation, oxidation) and biological methods (such as microbial treatment, plant purification), but most existing technologies are implemented using a single technical path.
[0003] Physical adsorption method: Physical adsorption method represented by activated carbon plays an important role in the field of water purification. This technology is relatively simple to operate, has good effects on low-concentration pollutants, and the adsorbent is regenerable. However, its inherent adsorption selectivity is low and the adsorption capacity is limited. The economic efficiency of treating high-concentration wastewater is poor. The regeneration cost and adsorbent loss are high, as well as the disposal of waste adsorbents have restricted the wider application and efficiency improvement of this technology.
[0004] Plant purification method: For biological methods, it is usually carried out by planting submerged plants that can purify water bodies on the bottom of the water. Submerged plants refer to large aquatic plants whose entire plant body is located below the water layer and survives. Their roots are sometimes underdeveloped or degenerate, and each part of the plant body can absorb water and nutrients. The aeration tissue is particularly developed, which is conducive to gas exchange in the absence of air in the water. There are two ways to artificially plant submerged plants on the bottom of the water: sowing and transplanting. Sowing has requirements for the flow rate and depth of the water body. If the water flow is too fast, it may cause the seeds to flow to other places with the water flow, resulting in no submerged plants growing in the area to be planted. Therefore, most of the existing technologies use the transplanting method.
[0005] Traditional submerged plants are generally planted by artificial cuttings, which is inefficient and costly. In the prior art, there are also methods of planting submerged plants using planting carriers, such as using soil to wrap the roots of submerged plants, and wrapping an isolation layer outside the soil. After the carrier is placed on the bottom of the water, the isolation layer will slowly decompose or break, at which time the roots of the submerged plants will be exposed and take root on the bottom of the water for subsequent growth. However, after the isolation layer is damaged, the soil inside may be quickly dispersed by the flushing of the water flow. If the roots of the plant have not taken root at this time, they may be washed away by the water flow. In other words, the above method leaves a short time for the plant roots to take root, and it is not easy for the plants to take root.
[0006] In addition, since current water purification mostly adopts a single purification mode of physical, chemical, and biological methods, functional coupling is not achieved, it is difficult to achieve the purification effect of water bodies. Summary of the Invention
[0007] In view of this, the present invention provides a water-purifying submerged plant degradable planting carrier to solve the problem in the prior art that submerged plants are difficult to take root during the planting process and the purification effect on the water body is poor due to the use of a single purification method; the present invention also provides a submerged plant planting method to solve the above technical problems.
[0008] A water purification type submerged plant degradable planting carrier includes a degradable material and bottom mud so that the carrier can slowly degrade in water. The carrier also includes a pollutant adsorption material for adsorbing pollutants in the water. The carrier is provided with a penetration hole for the stem diameter of the submerged plant to pass through and be fixed relative to the carrier. The penetration hole is also provided with a tying rope for tying the submerged plant to the carrier.
[0009] Furthermore, the binding rope is used to be wound around the stem diameter of the submerged plant and then tied to the hole wall of the installation hole.
[0010] Furthermore, the carrier components include 15%-30% of bottom mud, 35%-48% of degradable gel material, 1%-2% of foaming agent and 15%-18% of adsorbent.
[0011] Furthermore, the bottom mud is disinfected lake mud, the degradable gel material includes diatomaceous earth and zeolite, the pollutant adsorption material includes activated carbon, and the foaming material includes a degradable polyurethane foaming agent.
[0012] The beneficial effects of the water-purifying submerged plant degradable planting carrier of the present invention are as follows: the present invention uses degradable materials and bottom mud to make the planting carrier, and the bottom mud is used to increase the weight of the carrier, so that the carrier can sink to the bottom of the water when in use. By setting the through-holes and allowing the stem diameter of the submerged plants to pass through, on the one hand, it is convenient to limit the submerged plants, to connect the submerged plants and the carrier together, and to use the weight of the carrier to bring the plants to the bottom of the water, so that the submerged plants can take root at the bottom of the water, and provide a fixed attachment point for the initial growth of the plants; on the other hand, it is convenient for the roots of the submerged plants to be exposed to the outside, so that the plants can take root; the degradable materials facilitate the decomposition of the carrier at the bottom of the water, so that the submerged plants can take root. In the subsequent growth process of the submerged plants, the influence of the carrier on the growth of the submerged plants themselves is reduced; by setting the binding rope, the submerged plants can be more firmly connected to the carrier, avoiding the influence of water flow and aquatic organisms, ensuring that the submerged plants can contact the bottom mud in the early stage, which is convenient for growth; in addition, since the carrier is also provided with pollutant adsorption material, the pollutants in the water body can also be adsorbed through the carrier. When used, the plant purification and physical adsorption can be functionally coupled to improve the water purification capacity, thereby solving the problem in the existing technology that submerged plants are not easy to take root during the planting process and the purification effect on the water body is poor due to the use of a single purification method.
[0013] A method for planting submerged plants comprises the following steps: firstly, making a carrier comprising a degradable material, a pollutant adsorption material for adsorbing pollutants in water, and bottom mud; then, threading the stems of the submerged plants onto the carrier, keeping the roots of the submerged plants exposed; and using binding ropes to maintain the relative position of the submerged plants and the carrier. Then, the carrier together with the submerged plants is placed on the bottom of the water.
[0014] Furthermore, after the stems of the submerged plants are connected to the carrier, the carrier together with the submerged plants is thrown into the area to be planted.
[0015] Furthermore, the water depth is judged before throwing. If the water depth is less than 50CM, it is thrown directly to the area to be planted; if the water depth is greater than 50CM, the carrier and the submerged plants are sent to the top of the area to be planted, and then the carrier and the submerged plants are pressed below the water surface and allowed to settle naturally.
[0016] Furthermore, the bottom mud is disinfected before use.
[0017] The beneficial effects of the submerged plant planting method of the present invention are as follows: the present invention uses degradable materials and bottom mud to make planting carriers, and the bottom mud is used to increase the weight of the carrier, so that the carrier sinks to the bottom of the water when in use, and the degradable material is used to decompose the carrier at the bottom of the water, which is convenient for the submerged plants to grow in the subsequent process, thereby reducing the impact of the carrier on the growth of the submerged plants themselves; by using pollutant adsorption materials, pollutants in the water are conveniently adsorbed, and the pollutant treatment capacity is improved. Moreover, since the pollutant adsorption capacity of plants is relatively weak in the early stage of growth, adding pollutant adsorption materials to the planting carrier can make up for the lack of adsorption capacity in the early stage of plant growth; by using binding ropes to maintain the relative position of the submerged plants and the carrier, on the one hand, it is convenient to limit the submerged plants and connect the submerged plants and the carrier together, and on the other hand, it is convenient for the roots of the submerged plants to be exposed to the outside, so that the submerged plants can take root at the bottom of the water; thereby solving the problem in the prior art that submerged plants are not easy to take root during the planting process.

[0028] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.
[0029] In Example 1 of the water-purifying submerged plant degradable planting carrier (hereinafter referred to as carrier) of the present invention:
[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the carrier 1 is constructed of degradable materials and bottom mud. Specifically, the components of the carrier 1 include 15%-30% bottom mud, 35%-48% degradable gel material, 1%-2% foaming agent and 15%-18% adsorbent. The carrier 1 is annular as a whole, and a penetration hole 11 for the stem diameter of the submerged plant 3 to pass through is provided at its center. The diameter of the penetration hole 11 is determined according to the stem diameter of the submerged plant 3. The specific aperture of the penetration hole 11 should be larger than the aperture of the stem diameter and slightly smaller than the size of the root system. Since the plant root system can be squeezed, it can pass through the penetration hole 11 and remain exposed, thereby preventing the submerged plant 3 from falling out of the penetration hole 11 to a certain extent. At the bottom of the water, there will naturally be the influence of water flow and aquatic animals. In the early stage of planting, the roots of the submerged plants 3 are not well anchored to the bottom of the water. Therefore, it is necessary to maintain a stable connection between the submerged plants 3 and the carrier 1. Specifically, a binding rope 2 is also provided on the carrier 1. In this embodiment, the binding rope 2 is a cotton rope. After the cotton rope is wrapped around the rod diameter of the submerged plant 3 several times, it is tied to the wall of the hole 11, so that it can be temporarily fixed before the roots of the submerged plants grow on the bottom of the water.
[0031] In this embodiment, the bottom mud is disinfected lake mud, the degradable gel material includes diatomaceous earth and zeolite, the pollutant adsorbent material includes activated carbon, and the foaming material includes a degradable polyurethane foaming agent. The arrangement of the bottom mud facilitates the weight and average density of the carrier 1, making it convenient for the carrier 1 to sink to the bottom of the water with the submerged plants 3 during use, facilitating the rooting of the submerged plants 3; disinfecting the lake mud prevents bacteria and microorganisms carried by the lake mud from affecting the growth of the submerged plants 3 during the growth process. By providing diatomaceous earth and zeolite, on the one hand, the porous material properties are utilized to facilitate the exchange of roots with the surrounding water, and at the same time, a certain amount of pollutants in the water area can be adsorbed. By adding the degradable gel material, the degradation of the carrier 1 is facilitated. During the growth of the submerged plants 3, their roots and stem diameter will gradually increase. If the carrier 1 is always present, it will affect the growth of the submerged plants 3. Therefore, by controlling the addition of the degradable gel material, the degradation rate is controlled. In this embodiment, the degradation time of the carrier 1 is maintained at 30-90 days, without affecting the normal growth of the submerged plants 3. The addition of the foaming material maintains the interstices of the carrier 1, and the foaming material can be pre-soaked in nutrient solution to facilitate initial plant growth. The addition of the pollutant adsorbent material also enables the carrier 1 to have a physical adsorption function, which can simultaneously remove inorganic nitrogen and phosphorus, difficult-to-degrade organic matter, and heavy metals from the water, further enhancing the water purification capacity.
[0032] The carrier 1 has good sedimentation properties and can sink to the bottom of the riverbed. It is not easily affected by the speed of the water flow and is not easily displaced. A single planting carrier 1 is more suitable for planting areas with winding rivers and different water depths and elevations. The entire planting process does not require drainage and precipitation operations, which simplifies the planting process and reduces labor costs. There will be no floating grass in deep water areas, and the roots are not easily broken, which improves the planting survival rate. The carrier 1 can quickly absorb a large amount of suspended matter in the water body, while inhibiting the resuspension of the bottom mud, significantly improving the transparency of the water body in a short period of time, facilitating plant photosynthesis, and increasing the oxygen content in the water body. In addition, it can also absorb and remove nitrogen and phosphorus, difficult-to-degrade organic matter and heavy metals in the water body, ultimately achieving the purpose of removing pollutants and purifying water quality.
[0033] That is, in this embodiment, by providing a carrier composed of a specific formula and structure, it is convenient for the carrier to drive the submerged plants to overcome the buoyancy of the water and reach the bottom of the water by its own weight, assist the submerged plants to sink to the bottom, provide a fixed attachment point for the initial growth of the plants, and promote the plants to take root in the bottom of the water as soon as possible. Since the carrier contains degradable materials, by controlling the proportion thereof, the carrier is gradually disintegrated within 30-90 days, avoiding the submerged plants being set in the penetration holes and affecting the later growth and development of the plants. In addition, the inclusion of adsorbents in the carrier can simultaneously remove nitrogen and phosphorus, difficult-to-degrade organic matter and heavy metals in the water, functionally couple plant purification (biological method) with physical adsorption (physical method), and form a "bio-physical" synergistic purification system. Especially in the early stages of plant growth, when the purification capacity of the plant itself is insufficient, the addition of pollutant adsorption materials can be coordinated with the adsorption effect of the plant, so that a good pollutant treatment capacity is always maintained.
[0034] In the embodiment of the submerged plant planting method (hereinafter referred to as planting method) of the present invention:
[0035] The planting method in this embodiment is explained based on the above-mentioned water-purifying submerged plant degradable planting carrier. First, a carrier 1 composed of degradable materials and bottom mud is produced. The materials and production methods can refer to the materials and production methods in the embodiment of the water-purifying submerged plant degradable planting carrier. The stem of the submerged plant 3 is installed on the installation hole 11 of the carrier 1, and its root system is kept exposed. Then, a binding rope 2 is used to wrap around the stem of the submerged plant 3, and the binding rope 2 is tied to the hole wall of the installation hole 11 of the carrier 1. At this time, the submerged plant 3 and the stem have maintained a tightly connected state with the carrier 1. At this time, the carrier 1 needs to be sunk to the bottom of the water together with the submerged plant 3 to facilitate the growth and development of the submerged plant 3. In this embodiment, the throwing method is used for planting. Before throwing, it is necessary to judge the water depth. If the water depth is less than 50CM, the carrier and the connected submerged plants are directly thrown to the area to be planted; if the water depth is greater than 50CM, a ship can be used to carry the carrier 1 and the connected submerged plants to the top of the area to be planted, and the carrier and the submerged plants are pressed below the water surface and then released to allow them to sink naturally. Since the carrier itself is heavier than the submerged plants, the heavier end of the carrier will be located at the bottom during the process of sinking from the water surface, thereby causing the roots of the plants to be located at the bottom. Of course, in other embodiments, if the water depth is shallow, the carrier and the submerged plants can also be placed directly on the bottom of the water manually.
[0036] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
