Description

Technical Field

[0001] The present application relates to the field of river management and maintenance technology, and specifically to a river purification module. Background Art

[0002] At present, due to the rapid development of urbanization, more and more rivers in cities are being transformed to provide venues for leisure and entertainment for urban residents.

[0003] In the natural environment, floating aquatic plants such as water hyacinth can absorb a large amount of nitrogen, phosphorus, and heavy metal elements such as cadmium, chromium, cobalt, nickel, lead and mercury in the water during their growth, and can even remove cyanide, which is more effective in purifying industrial wastewater or domestic sewage containing more organic matter. At the same time, water hyacinth grows quickly, is easy to plant, and can be used as organic fertilizer or feed, with high economic value.

[0004] However, since water hyacinth is an invasive alien plant, it is easy to cause flooding and even block rivers and lakes, affecting water transportation. At the same time, floating aquatic plants themselves are difficult to resist wind, rain and rapid currents, and the effect of their use is not satisfactory. Utility Model Content

[0005] The main purpose of the present application is to provide a river purification module, which aims to solve the problem that floating aquatic plants used to purify water bodies are difficult to resist wind, rain and rapid currents and float around, and it is difficult to constrain and control the plant growth space, resulting in plant flooding.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] First: A river purification module proposed in this application uses multiple modules to form a whole, and uses a fence frame to restrain floating aquatic plants. It can have a certain resistance to wind, rain and rapid water flow, and prevent floating aquatic plants from floating around. It can restrain and control the growth and space of plants to avoid plant proliferation. At the same time, the floating aquatic plants in the fence frame can not only purify the water body, but also beautify the urban environment, enhance the image and quality of the city, and also have certain economic value.

[0025] See attached Figure 1 to Figure 2 The embodiment of the present application provides a river purification module, including a buoyancy frame 1, a fence frame 2 and a purification block 3. The fence frame 2 is arranged on the top of the buoyancy frame 1. The buoyancy frame 1 is a grid-like frame structure composed of hollow tubes. Floating aquatic plants (such as water hyacinth) are placed into the fence frame 2 from the frame. The fence frame 2 is used to constrain the floating aquatic plants in the frame. The buoyancy frame 1 is used to make the fence frame 2 float on the water surface. The purification block 3 is arranged at the bottom of the buoyancy frame 1, and the purification block 3 is provided with a filter material for purifying water.

[0026] When used, several purification modules are connected into a whole by structural adhesive (such as Figure 4As shown), and fixed around the bridge pier or the river bank, water plants such as water hyacinth that purify the water body are placed from the buoyancy frame 1, and the fence frame 2 is used to constrain the aquatic plants to float around. The hollow buoyancy frame 1 provides a growth space for the root system of the water hyacinth, and the buoyancy frame 1 is a hollow structure that can provide enough buoyancy to make the purification module float on the surface of the river. In the later stage, if there are too many water hyacinths on it, floating blocks can be filled inside the buoyancy frame 1 to improve the buoyancy of the purification module. At the same time, there is a lot of space inside the buoyancy frame 1, which can accommodate fish in the water and provide nutrients for aquatic species. In this embodiment, the fence frame 2 is made of wire mesh to constrain the water hyacinth and prevent the water hyacinth from leaking out of the purification module to pollute the river. The wire mesh and the buoyancy frame 1 can be fixed by a rolling belt. In the later stage, if there are too many water hyacinths, the wire mesh can be opened to remove some of the water hyacinths, so that the planting density of the purification module is maintained within a reasonable range. At the same time, the removed water hyacinths can also create economic value.

[0027] Furthermore, a purification block 3 is arranged at the bottom of the buoyancy frame 1. The purification block 3 is made of polymerized volcanic rock and medical stone into a disc-shaped porous structure. The purification block 3 has the characteristics of high porosity and high surface area. Its pore structure provides a large amount of growth space for nitrifying bacteria and other microorganisms, thereby enhancing the effect of biological filtration. In this embodiment, the porous structure of the purification block 3 can intercept suspended particles in the water, such as fish excrement, food residues, etc. These particles are trapped on the surface and pores of the purification block 3 to prevent the particles from continuing to pollute the water body. And because the surface area of ​​the purification block 3 is large, nitrifying bacteria can multiply in large quantities on its surface and pores. These bacteria can convert ammonia (NH3) into nitrite (NO2-), and further convert it into nitrate (NO3-), thereby reducing the content of toxic substances in the water. In addition, the purification block 3 is rich in various minerals, such as iron, magnesium, calcium, etc., which not only have the ability to adsorb harmful chemicals, but also dissolve in water, which can provide necessary nutrition for aquatic plants and fish.

[0028] More specifically, among the above, Figure 1 to Figure 2 As shown, the bottom of the buoyancy frame 1 is integrally designed with a plurality of vertical support rods, and a plurality of purification blocks 3 are arranged at equal intervals on each support rod to expand the surface area in contact with the water body, so that the water flows through the gaps between the purification blocks 3 and the nitrifying bacteria in the purification blocks 3 are used to purify the water body.

[0029] To install the purification block 3 on the support rod, as shown in FIG. Figure 3As shown, a plurality of spring round pins 5 are arranged on the outer wall of the support rod, and the purification block 3 is disc-shaped, with a through hole running through the middle thereof, and the purification block 3 is sleeved on the support rod through the through hole, and a positioning pin hole is arranged on the side wall of the through hole of the purification block 3. When the purification block 3 is sleeved on the support rod, the spring round pin 5 is correspondingly inserted into the positioning pin hole to complete the installation of the purification block 3. In addition, in this embodiment, a certain gap is maintained between adjacent support rods, and the purification block 3 is circular, so that the roots of the water hyacinth can grow freely at the bottom in the later stage, and more roots can absorb more heavy metal ions in the water, such as cadmium, lead, mercury, thallium, silver, cobalt, strontium, etc. At the same time, the strong root system can provide a good growth environment for microorganisms, promote the biodegradation of pollutants, and can also be used as bait for fish and provide certain shelter for fish seedlings. The purification block 3 and the support rod are designed as a detachable structure to facilitate the replacement of the purification block 3. As a filter material, the purification block 3 in the later stage is easy to adhere to dirt and other harmful substances, and can be cleaned regularly once every six months or a year. When the purification block 3 is soaked for a long time or the iron, calcium and other elements in the purification block 3 are oxidized, the strength of the purification block 3 decreases, and powdering and damage occur, which need to be replaced in time. At the same time, the existence of the purification block 3 can increase the overall weight of the purification module, making the purification module float more stably in the water.
