Description

Technical Field

[0001] The utility model relates to the technical field of river water purification equipment, in particular to a biological purifier used for river water. Background Art

[0002] Water is the basic condition for human survival and an indispensable condition for maintaining the stability of the ecological environment system. In recent years, with the rapid development of society, urban residents have paid more and more attention to the quality of their living environment. Many urban parks, artificial lakes, etc. have appeared one after another. At the same time, many urban landscape water pollution problems have emerged. The eutrophication and odor of landscape water bodies have become increasingly serious. The destruction of the water environment ecosystem has brought varying degrees of impact on the lives of urban residents. In order to improve water quality, the existing technology will place biological purifiers in rivers and creeks and other locations.

[0003] In order to improve the water quality of rivers and streams, the prior art has made many improvements to the biological purifiers of river and stream water bodies. For example, the patent with the patent publication number of CN218755256U discloses a biological purifier for river and stream water bodies, including: a biological floating island; an anaerobic biological reaction chamber arranged below the biological floating island, the bottom of the anaerobic biological reaction chamber is provided with a water inlet connected to the outside world; an aerobic biological reaction chamber arranged below the biological floating island and located outside the anaerobic biological reaction chamber, the aerobic biological reaction chamber is connected to the biological floating island and its outside is provided with a water outlet connected to the outside world; a denitrifying bacteria filler arranged in the anaerobic biological reaction chamber; a suspended biological filler arranged in the aerobic biological reaction chamber; and a lifting pump arranged on the biological floating island, the input end of the lifting pump penetrates into the anaerobic biological reaction chamber. The biological purifier of the utility model has a simple appearance. When floating in the river and working, the biological floating island can effectively shield the anaerobic biological reaction chamber and the aerobic biological reaction chamber at the bottom, so that the biological purifier can be reasonably and naturally integrated into the surrounding landscape, which is conducive to environmental coordination.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative documents, by placing biological floating islands on the surface of rivers and creeks, planting emergent plants on the biological floating islands, and cooperating with aerobic biological reaction chambers and anaerobic biological generation chambers in the biological floating islands, the overall device purifies the water quality in the rivers and creeks. However, in reality, the large-scale reproduction of emergent plants will cause the water quality to deteriorate, because a large number of emergent plants cover the water, resulting in a reduction in the contact area between the water surface and the air, which is not conducive to the exchange of gas and air in the water, resulting in hypoxia in the water, the death of aquatic animals, and water pollution. In addition, because a large number of emergent plants cover the water, insufficient sunlight exposure affects the light absorption of underwater submerged plants, resulting in the death of submerged plants and water pollution. Therefore, it is necessary to regularly maintain the emergent plants on the biological floating islands, such as ensuring the coverage area of ​​the emergent plants, or it is necessary to maintain the devices in the biological floating islands. In the prior art, when maintaining the emergent devices or internal devices on the biological floating islands, maintenance personnel need to row a boat to reach the biological floating islands placed on the surface of the river, resulting in a more cumbersome maintenance process. Therefore, there is an urgent need in the art to improve the biological purifiers used for river water bodies to solve the defects of the prior art. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-Figure 5 A biological purifier for river water bodies comprises a plurality of biological purification device bodies floating on a riverbed 2, each biological purification device body being composed of two biological floating islands 1, the two biological floating islands 1 being symmetrical and arranged in a V shape, the two biological floating islands 1 forming a V-shaped opening facing the downstream direction of the riverbed 2, the two biological floating islands 1 being able to be separated from the middle part, the opposite ends of each biological floating island 1 being connected to the sides of a river bank 3 on both sides of the riverbed 2, a fixing device 4 being provided on the upper surface of the river bank 3, a fixing rod 5 having one end inserted into the bottom of the riverbed 2 being provided on the fixing device 4, the fixing rod 5 passing through one end of the biological floating island 1, and the biological floating island 1 being able to rotate along the fixing rod 5 as the axis, a fixing column 6 being provided at one end of the biological floating island 1 away from the fixing rod 5, a traction rope 7 being wound around the side of the fixing column 6, an end of the traction rope 7 away from the fixing column 6 extending to the river bank 3, and aquatic plants being provided on the biological floating island 1.

[0027] The biological purification device body has the same function as the biological purifier in the prior art. For example, the patent publication number CN218755256U discloses a biological purifier for river water bodies, in which the biological floating island 1 is provided with an aerobic biological reaction chamber and an anaerobic biological generation chamber, etc. The main principles are the same as those of the prior art. The main problem solved by this embodiment is to facilitate the maintenance personnel to maintain the biological floating island 1 and the aquatic plants cultivated on the biological floating island 1 in the later stage. During installation, the position where the biological floating island 1 is to be placed is first measured. The fixing rod 5 is inserted into the bottom of the riverbed 2 by a machine, one end of the biological floating island 1 is passed through the side of the fixing rod 5 and placed on the water surface of the riverbed 2, and the upper end of the fixing rod 5 is fixed by the fixing device 4, or two biological floating islands 1 are first spliced ​​into a V shape and placed on the water surface of the riverbed 2, and the position is determined for temporary fixation, and the fixing rod 5 is passed through the through hole opened on the biological floating island 1 by a machine and inserted into the bottom of the riverbed 2, and the upper end of the fixing rod 5 is fixed by the fixing device 4. The above two installation methods are used to install each group of biological floating islands 1. During installation, one end of the traction rope 7 is tied to the fixed column 6, and the other end of the traction rope 7 is left on the river bank 3. After the biological floating island 1 is installed, the end of the traction rope 7 left on the river bank 3 is pulled to pull one end of the biological floating island 1, and the biological floating island 1 is rotated along the fixed rod 5 as the axis, and then the biological floating island 1 is rotated to be attached to the side of the river bank 3, which is convenient for the installers to cultivate aquatic plants. After the cultivation of aquatic plants is completed, the two biological floating islands 1 are pushed to the middle of the river bed 2 by the long rod until the ends of the two biological floating islands 1 are The two biological floating islands 1 are attached to each other, and are V-shaped on the riverbed 2, with the V-shaped opening facing the downstream direction. Due to the impact of the water flow, the middle parts of the two biological floating islands 1 do not need to be connected, and can cover the entire water surface on the riverbed 2, thereby improving the effect of purifying the water quality in the riverbed 2. During later maintenance, it is only necessary to pull the traction rope 7 to pull the biological floating island 1 and move it close to the riverbank 3, which is convenient for later maintenance of the biological floating island 1 or aquatic plants. The fixing rod 5 is circular, and the biological floating island 1 can move with the change of the water level in the riverbed 2.

[0028] It is worth noting that the above-mentioned aquatic plants include but are not limited to calamus, calamus and cattail. The test results show that calamus has the best purification effect on TP, with a removal rate of 91.3%, calamus has the best purification effect on ammonia nitrogen, with a removal rate of 94.8%, and cattail has the best purification effect on COD, with a removal rate of 40.2%. Through the release of the above-mentioned aquatic plants, it is concluded through test data that after HRT reaches 120h, the removal rates of TP, ammonia nitrogen, TN, and COD reach 68.7%, 92.9%, 90.9% and 74.7%, respectively, and the comprehensive water quality pollution index drops from 36.0 to 6.2. Aquatic plants such as calamus and calamus have the best purification effect. At the same time, the biological floating island 1 cultivated with the above-mentioned aquatic plants can effectively reduce the main pollutant indicators in the river water during dynamic continuous operation, and can maintain a good purification effect under different seasonal conditions.
