Description

Technical Field

[0001] The invention belongs to the field of lake water treatment technology, and in particular relates to a high-efficiency phosphorus removal device for lake water bodies. Background Art

[0002] In the field of sewage treatment, phosphorus removal is of vital importance. Phosphorus in sewage is circulated and transformed in solid and dissolved forms. Sewage phosphorus removal technologies mainly include chemical phosphorus removal and biological phosphorus removal. Chemical phosphorus removal allows phosphorus to form insoluble solid precipitates and separate from sewage; biological phosphorus removal allows phosphorus to be absorbed by microorganisms in a dissolved state and separated from sewage along with microorganisms.

[0003] At present, for river water bodies, phosphorus removal is also urgent. If phosphorus is not removed in time, the water body is prone to eutrophication, which will cause blue algae outbreaks and severely compress the living space of aquatic organisms such as fish and shrimp. At present, most of the phosphorus removal methods on the market for river water bodies are directly placed in the river water body. However, this method has many disadvantages. In rivers with fast water flow, it is difficult to ensure that the phosphorus removal agent is fully distributed in the river water body; when facing large-flow river water bodies, the phosphorus removal agent is diluted too quickly, resulting in low phosphorus removal efficiency; there are also some physical phosphorus removal methods, such as the Chinese patent with the authorized patent number CN207811316U, which discloses a lake phosphorus removal device, including a hollow plate-shaped floating platform, a breeding tank is set in the center of the floating platform, and there are hanging holes around it.

At the same time, the green plants planted in the net basket 3 can play a role in dephosphorization;

[0035] The high-efficiency phosphorus removal device for lake water provided by the present invention can effectively solve the problem of low phosphorus removal efficiency of current lake water phosphorus removal methods when facing high-concentration phosphorus pollution or large-area lakes.

[0036] In a further preferred embodiment of the present invention, the mixing mechanism includes: a water pumping pipe 8 fixedly connected to the bottom of the mixing cylinder 7, the water outlet end of the water pumping pipe 8 extending out of the assembly box 1 for pumping water from the lake; a rotating rod 10 rotatably installed in the mixing cylinder 7 through a sealed bearing, an impeller 11 fixedly installed on the rotating rod 10; a diverter plate fixedly installed in the mixing cylinder 7 for separating channels; and a water outlet pipe 12 fixedly connected to the top of the mixing cylinder 7, the water outlet end of the water outlet pipe 12 extending into the filter tank 4.

[0037] In this embodiment, a water pumping pipe 8 is fixedly connected to the bottom of the mixing barrel 7, and its outlet end extends outside the assembly box 1, so as to draw lake water from the lake and introduce the lake water into the mixing barrel 7; the rotating rod 10 installed in the mixing barrel 7 rotates through a sealed bearing, and the impeller 11 fixed on the rotating rod 10 rotates with the rotation of the rotating rod 10, so as to stir and mix the lake water entering the mixing barrel 7 and the dephosphorization liquid injected from the drug supply pipe 9, so that the two are fully blended; the diverter plate in the mixing barrel 7 plays the role of separating the channels, optimizing the water flow path in the mixing barrel 7, so that the lake water and the liquid can flow and mix more orderly in the mixing barrel 7; the lake water after being fully mixed passes through the water outlet pipe 12 fixedly connected to the top of the mixing barrel 7, and its outlet end extends into the filter tank 4, and the mixed liquid is transported to the filter tank 4 for subsequent treatment;

[0038] The design of the mixing mechanism in the present invention further improves the phosphorus removal effect of the high-efficiency phosphorus removal device for lake water bodies. A series of operations such as extracting lake water through the pumping pipe 8, stirring and mixing with the impeller 11, optimizing the path of the diverter plate, and conveying the mixed solution through the outlet pipe 12 can ensure that the lake water and the phosphorus removal solution are fully mixed in the mixing barrel 7, so that the effect of chemical phosphorus removal can be better exerted, thereby more effectively removing the phosphorus element in the lake water body and improving the phosphorus removal efficiency of the entire device; the setting of the pumping pipe 8 can stably extract lake water from the lake, provide sufficient lake water to be treated for the mixing barrel 7, and ensure the continuous progress of the phosphorus removal operation; the combination of the rotating rod 10 and the impeller 11 can strongly stir the lake water and the phosphorus removal solution, accelerate the mixing process of the two, so that the solution can be more evenly dispersed in the lake water, and give full play to the phosphorus removal effect; the diverter plate can reasonably guide the water flow in the mixing barrel 7 to avoid turbulence or short circuit of the water flow, thereby improving the uniformity and effect of mixing; the outlet pipe 12 can smoothly convey the evenly mixed lake water to the filter tank 4, provide a stable water supply for the subsequent filtering and purification steps, and ensure the smooth operation of the entire phosphorus removal device.

[0039] In a further preferred embodiment of the present invention, the boosting mechanism includes: a water pump 14 arranged in the filter tank 4 for pumping water; a connecting pipe 15 fixedly connected to the water outlet end of the water pump 14, and the water outlet end of the connecting pipe 15 extends into the filter box 5; and a first one-way valve 16 arranged on the connecting pipe 15 for controlling the opening and closing of the pipeline.

[0040] In this embodiment, after the lake water mixed by the mixing barrel 7 flows into the filter tank 4, the water pump 14 arranged in the filter tank 4 starts to work, and uses its water pumping function to extract the water in the filter tank 4; the water extracted by the water pump 14 is transported through the connecting pipe 15 fixedly connected to its water outlet end, and the water outlet end of the connecting pipe 15 extends into the filter box 5, thereby sending the water into the filter box 5; the first one-way valve 16 arranged on the connecting pipe 15 can control the on-off of the pipeline. When the water pump 14 is working to pump water, the first one-way valve 16 opens to allow water to flow from the filter tank 4 to the filter box 5; when the water pump 14 stops working, the first one-way valve 16 closes to prevent the water in the filter box 5 from flowing back into the filter tank 4, thereby ensuring the unidirectional direction of the water flow;

[0041] The boosting mechanism in the present invention further improves the operation process of the high-efficiency phosphorus removal device for lake water bodies. By pumping water through the water pump 14, delivering water through the connecting pipe 15, and controlling the direction of water flow through the first one-way valve 16, it is possible to ensure that the water in the filter tank 4 smoothly and stably enters the filter box 5 for further purification treatment, thereby improving the treatment efficiency of the device for lake water and enhancing the operating stability of the entire dephosphorization device, thereby more effectively removing the phosphorus element in the lake water body and improving the dephosphorization effect; the water pump 14, as the core component of the booster mechanism, can provide power for water to flow from the filter tank 4 to the filter box 5, ensuring the flow speed and pressure of water in the device, so that the subsequent filtering and purification steps can proceed smoothly; the connecting pipe 15 plays a role in stabilizing water delivery, accurately delivering the water pumped by the water pump 14 to the filter box 5, avoiding leakage and loss of water flow during the delivery process, and ensuring the continuity of the entire dephosphorization process; the setting of the first one-way valve 16 effectively prevents the backflow of water in the filter box 5, avoids pollution and device operation failures that may be caused by the backflow of water, improves the reliability and safety of the device, and also ensures that the water flows in the device in a predetermined direction, thereby improving the efficiency of the dephosphorization operation.

In this way, the assembly box 1 is firmly fixed in the lake to prevent the device from moving arbitrarily due to factors such as water flow; the arrangement of the connection base 22, the rope ring 23, the steel wire rope 24 and the pointed cone rod 25 on the assembly box 1 in the present invention further enhances the practicality and stability of the high-efficiency phosphorus removal device for lake water bodies. The connecting seat 22 can realize the series connection of the device, improve the flexibility and scalability of the device, and can adjust the number of devices according to the phosphorus removal requirements of different lakes; and the combination of the rope ring 23, the wire rope 24 and the pointed cone rod 25 ensures the fixation of the device in the lake, so that the device remains stable during operation, ensuring the continuous and effective phosphorus removal operation, thereby improving the phosphorus removal effect of the entire phosphorus removal device on the lake water body;

[0044] The presence of the connecting seat 22 enables multiple phosphorus removal devices to be conveniently connected in series. When facing phosphorus removal work in a large area of ​​lakes, the number of devices can be flexibly increased, the phosphorus removal efficiency can be improved, the phosphorus removal range can be expanded, and the actual phosphorus removal needs can be better met; the rope ring 23 serves as a connecting component between the wire rope 24 and the assembly box 1, providing a reliable connection point to ensure the stability of the connection between the wire rope 24 and the assembly box 1; the wire rope 24 has high strength and toughness and can withstand a certain amount of tension, firmly connecting the assembly box 1 with the pointed cone rod 25, and playing a stable traction role in the process of fixing the device; the pointed cone rod 25 can be easily inserted into the lakeshore soil, providing a stable fixing point for the entire device, so that the assembly box 1 can maintain a relatively fixed position in the lake, avoiding the impact of water flow and other factors that cause the position of the device to change and affect the phosphorus removal effect.

The planting basket 17 is used to hold the filter material and plant the green plants, so that the green plants and the filter material can be easily managed and replaced; when the planting basket 17 needs to be operated, such as adding filter material, replacing green plants, or checking the internal conditions, the planting basket 17 can be taken out of the net basket 3 by grasping the handles symmetrically fixed on the planting basket 17, and then put back into the net basket 3 after the operation is completed;

[0047] In the present invention, a detachable planting basket 17 and a matching handle are provided in the net basket 3, which further optimizes the phosphorus removal method and the convenience of operation of the efficient phosphorus removal device for lake water. The planting basket 17 can hold filter materials and plant phosphorus removal plants, and combines the physical filtration of the filter materials with the biological phosphorus removal of the plants to improve the phosphorus removal effect; the detachable design and the setting of the gripping handle facilitate the maintenance and replacement of the filter materials and plants in the planting basket 17, ensuring that the device can continuously and effectively remove phosphorus from the lake water, and enhancing the practicality and operability of the entire phosphorus removal device;

[0048] The net basket 3 provides an installation carrier for the planting basket 17, so that the planting basket 17 can be stably set on the phosphorus removal device. At the same time, the structure of the net basket 3 helps the lake water to fully contact the filter material and green plants in the planting basket 17, thereby improving the phosphorus removal efficiency. The detachable planting basket 17 design makes the replacement of filter materials and green plants more flexible. When the filter material loses its filtering effect or the green plants grow poorly, the planting basket 17 can be easily taken out and replaced to ensure that the phosphorus removal device is always in good working condition.
