Description

Technical Field

[0001] The utility model relates to the field of water pollution treatment, in particular to a river pollution treatment device. Background Art

[0002] The existing river sewage treatment methods are mainly divided into three types, namely physical method, chemical method and biological method. Among them, the physical method includes sewage interception method, dredging method, aeration and reoxygenation method, and water replacement and dilution; the chemical method is mainly a method of adding certain chemical reagents for treatment; the biological method is mainly a method of planting aquatic organisms to purify polluted water. These methods all have certain limitations.

[0003] Sewage interception method: The sewage interception method of building a new sewage interception pipe to intercept sewage and then transporting it to a sewage treatment facility for treatment. The disadvantage of this method is that the river sewage interception project is huge, involving a wide range, including a large number of pipeline laying, sewage treatment plant construction, personnel relocation, ecological restoration around the river, and sewage control of factories and enterprises. The project investment is high, the construction period is long, and the project implementation is complex.

[0004] Dredging method: Using machinery to remove the bottom mud from the river body can reduce the nutrients accumulated in the surface bottom mud and reduce potential internal pollution sources, which is a direct and effective measure to reduce endogenous pollution. However, after dredging, the water quality can only be improved temporarily. With the input of pollution, the river will soon silt up again, and the project volume is large and the investment cost is high.

[0005] Aeration and reoxygenation method: Artificial oxygenation is carried out on a river in an anoxic (or anaerobic) state (this process is called river aeration and reoxygenation), which can enhance the self-purification ability of the river, improve water quality, and improve or restore the ecological environment of the river. However, the aeration and reoxygenation method has a high operation cost and a large operation difficulty.

[0006] Water replacement and dilution method: A method of diverting water through engineering means to dilute the polluted water body and reduce the pollution load of the water body in a short time. However, the total amount of pollution does not decrease after water replacement and dilution. In fact, it is the transfer of pollutants. If the external pollution persists, it will soon return to the original pollution level, and high-quality water resources are wasted.

[0007] The chemical method is to add corresponding chemical agents according to the pollution characteristics of the river to forcibly remove pollutants. This method is simple to operate, but the cost is high and it is easy to cause secondary pollution.

[0008] Aquatic plant treatment method: Using the aquatic biological method to plant aquatic plants, and transferring the pollution load in the water body system through the growth of plants. Its developed root system provides a place for the growth and reproduction of microorganisms to decompose pollutants in the water for plants to absorb, and has certain functions of absorption and purification, water clarification, and algae inhibition. The disadvantage of this method is that it requires a large amount of manpower, a long treatment period, and is difficult to maintain.

[0009] Bio-augmentation treatment method: Microorganisms are fixed and grown through certain technical means (such as using carrier materials, embedding substances, or reasonably controlling hydraulic conditions, etc.) to strengthen the microbial community to purify water bodies. The disadvantages of this method are complex process, difficult operation, large floor area, and long operation time.

[0010] Microbial preparation method: Select highly efficient strains to make microbial composite preparations to treat polluted water bodies. Its process is based on enzymatic reactions, using special proteins with catalytic functions produced in organisms as catalysts to purify sewage, decompose sludge, and eliminate odors. Its disadvantage is that to maintain good water body improvement effects, it needs to be continuously added according to the changes in the water body, and it can be used as an auxiliary measure in the process of water body ecological restoration.

[0011] Artificial floating island technology method: Through the absorption and utilization of essential elements such as nitrogen and phosphorus in water bodies by plants during growth, and the adsorption of suspended substances in water bodies by plant roots and floating bed substrates, etc., harmful substances in water bodies are enriched. At the same time, a large amount of secretions that can degrade organic matter are released from plant roots, thereby accelerating the decomposition of organic pollutants. The disadvantage of this method is that it takes a long time and cannot achieve immediate results.

[0012] A Chinese patent application with the publication number CN109264869A discloses a device system suitable for in-situ purification treatment of river channels. Its structure includes a metal support frame, a vegetation concrete block, a basalt fiber filler, and a plant floating bed. The metal support frame is fixed in the bottom mud of the river channel. A vegetation concrete block is laid at the bottom of the metal support frame. Aquatic plants are planted on the vegetation concrete block. The basalt fiber filler is suspended on the metal support frame. The metal support frame is connected to the floating bed through a connecting rope, so that the plant floating bed floats on the water surface, and aquatic plants are planted on the floating bed. The purification treatment effect of this technology needs to be improved. Utility Model Content

[0013] The technical problem to be solved by the present utility model is to provide a river pollution treatment device with high sewage treatment efficiency in view of the deficiencies of the prior art.

[0015] With the development of our country, due to the direct discharge problems of residents or factories on both sides of some urban rivers, the pollution is extremely serious. In order to control river pollution, it often requires a large amount of manpower and material resources, and the treatment process often brings adverse effects to the surrounding residents. For example, the river bottom dredging technology will emit stinky gas, and the sewage interception method will affect traffic when laying pipelines. Considering these problems, the present utility model provides a river pollution treatment device in view of the deficiencies of the prior art. When in use, the bottom of the plant planting bin is placed above the river water surface, and the membrane material placement frame is placed in the river water.

[0024] In a preferred embodiment of the present utility model, the plant planting bin includes a bottom of the plant planting bin and an outer wall of the plant planting bin, and the bottom of the plant planting bin is a hollow structure.

[0025] The bottom of the planting bin is composed of a hollow structure, preferably a hollow structure in a ring shape, which can enable the plant roots to fully contact the water body and absorb the pollution in the water body. The outer wall of the plant planting bin can prevent the plants from falling.

[0028] In a preferred embodiment of the present invention, the sliding frame is composed of a plurality of quadrilateral structures, and the quadrilateral structures can deform.

[0029] The sliding frame can change into different shapes according to the required water flow velocity.

[0030] In a preferred embodiment of the present invention, a first connecting rod and a second connecting rod are arranged on one side of the sliding frame. The first connecting rod is connected to the fixed frame, and the second connecting rod is slidably connected to the fixed frame.

[0031] In a preferred embodiment of the present invention, a sliding groove is arranged in the fixed frame, and a sliding roller is installed at the end of the second connecting rod. The sliding roller is clamped in the sliding groove.

[0032] The sliding roller can move in the sliding groove.

[0033] The sizes of the HDPE film and the polyurethane film are 15 - 25 mm.

[0034] The inner groove of the membrane material placement frame is a smooth surface, which is beneficial to the rotation of the membrane material placement frame along with the water flow.

Specific implementation mode

[0054] See Figures 1 to 10 , a river pollution treatment device, including a support base 1 and a film - carrying net bin 2.

[0055] As Figures 2 to 3 shown, the support base 1 includes a support frame 1.1, a sliding connector 1.2, sliding rollers 1.3, connecting round nails 1.4, vertical rods 1.5, sliding grooves 1.6, a fixed frame 1.7, and a sliding frame 1.8.

[0056] The support frame 1.1 is divided into two parts, namely the fixed frames 1.7 on both sides and the sliding frame 1.8 in the middle. The fixed frames are fixed on both sides of the riverbed and have sliding grooves 1.6 inside. The sliding frame 1.8 is connected to the fixed frame 1.7 under the action of the sliding connector 1.2.

[0057] As Figure 5 shown, the sliding frame 1.8 is connected by connecting round nails 1.4 and intersects to form a square - mesh structure, and as the sliding rollers 1.3 move in the sliding grooves 1.6, the sliding frame 1.8 can form different shapes, as Figure 6 shown. Vertical rods 1.5 are installed on the sliding frame 1.8.

[0058] As Figures 7 - 10 shown, the film - carrying net bin 2 includes a plant planting bin 2.1, a film material placement frame 2.2, and a connection buckle 2.3. Among them, the plant planting bin 2.1 includes the bottom 2.5 of the plant planting bin and the outer wall 2.4 of the plant planting bin, and the film material placement frame 2.2 includes the outer wall 2.6 of the film material placement frame, the inner groove 2.7 of the film material placement frame, and the inner cabin 2.8 of the film material placement frame.

[0059] The film - carrying net bin 2 can be removed from the support frame 1.1.

[0060] The film - carrying net bin 2 is generally cylindrical and is mainly divided into two functional areas. Among them, the plant planting bin 2.1 can be removed separately or connected to the film material placement frame 2.2 through the connection buckle 2.3 to form an integral structure.

[0061] The planting bin bottom 2.5 of the plant planting bin 2.1 is composed of a ring - shaped hollow structure, and the outer wall 2.4 of the plant planting bin is a sealed structure.

[0062] The membrane material placement frame 2.2 is cylindrical in shape, and its overall plane shape is an inverted concave. The outer wall 2.6 of the membrane material placement frame is a hard mesh structure, and sewage enters the inner chamber 2.8 of the membrane material placement frame through the mesh structure. The inner groove 2.7 of the membrane material placement frame is a smooth surface, and this part is connected to the vertical rod 1.5 when in use.

[0063] The outer wall of the membrane material placement frame is a hard mesh structure, which can support the entire membrane material placement frame.

[0064] Taking a certain test project as an example, the area is surrounded by residential areas. The main pollutants in the water body come from sewage discharged by residents. The organic matter and nitrogen and phosphorus content are high. However, the distance between the residents on both sides is close, and the use of other technologies will cause adverse effects. This time, the urban river pollution control equipment described in the utility model is considered to be used. The equipment is placed in the water body and the water body is purified by plant adsorption and membrane material treatment. This time, the aquatic plant calamus is planted in the plant planting warehouse, and two membrane materials are placed in the membrane material placement frame, namely, a membrane made of HDPE and a size of 20mm and a membrane made of polyurethane and a size of 20mm. Inorganic materials, such as ceramic membranes, are not recommended because ceramic membranes are relatively heavy, which will make the entire membrane-carrying net warehouse too heavy and not conducive to rotation. The membrane material will age after a period of use and needs to be replaced. Whether to replace it is determined based on the color change of the membrane material. If the white membrane material turns dark brown, it means that the membrane material needs to be replaced. As the river water flows downstream, it drives the entire membrane-carrying silo to rotate, so that the sewage is purified by the treatment of membrane materials and plant purification. Compared with the sewage interception method, there is sewage overflow this time, and the sewage interception method can only deal with areas where pipelines have been laid; compared with the dredging method, the dredging method is not suitable because it is too close to residents, and the odor emitted during the dredging process will affect normal life; compared with the aeration and reoxygenation method, it has lower energy consumption and is more economical; compared with the artificial floating island technology method, since the river channel is too narrow, it is not suitable to set up artificial floating islands, which will block the river channel.
