Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of lake water treatment, and particularly relates to a high-efficiency phosphorus removal device for lake water. BACKGROUND

[0002] In the field of sewage treatment, phosphorus removal is crucial. Phosphorus in sewage is cyclically transformed between solid and dissolved forms, and sewage phosphorus removal technologies mainly include chemical phosphorus removal and biological phosphorus removal. Chemical phosphorus removal is to make phosphorus form insoluble solid precipitates and separate from sewage, and biological phosphorus removal is to make phosphorus be taken up by microorganisms in a dissolved state and separate from sewage with microorganisms.

[0003] At present, phosphorus removal is also urgent for river water. If phosphorus is not removed in time, the water body is prone to eutrophication, which in turn triggers an outbreak of blue-green algae, severely reducing the living space of fish and shrimp and other aquatic organisms. At present, most of the phosphorus removal methods for river water on the market directly add phosphorus removal agents to the river water. However, this method has many drawbacks. In fast-flowing rivers, it is difficult to ensure that the phosphorus removal agent is fully distributed throughout the river water; in the face of large-flow river water, 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 authorization patent number CN207811316U, which discloses a lake phosphorus removal device, including a plate-shaped floating platform with an internal hollow core, a breeding tank is arranged at the center of the floating platform, and there are suspension holes around the floating platform, a water-permeable mesh bag filled with phosphorus removal material is suspended in the suspension holes through a lifting rope, although this device has many advantages such as not damaging the lake ecosystem, its phosphorus removal efficiency is still not ideal when facing high-concentration phosphorus pollution or large-area lake water, and it is difficult to efficiently reduce the phosphorus content in the water.

[0035] The high-efficiency phosphorus removal device for lake water bodies provided by the present application can effectively solve the problem of low phosphorus removal efficiency of the current lake water body phosphorus removal method when facing high-concentration phosphorus pollution or large-area lakes. By combining multiple phosphorus removal methods, i.e., chemical phosphorus removal of phosphorus removal liquid, physical filtration of filter material, and biological phosphorus removal of green plants, the phosphorus removal effect in lake water bodies is improved, and the phosphorus content in water bodies can be more efficiently reduced. The design of the assembly box 1 and the suspension box 18 enables the device to stably float on the surface of the lake, facilitating phosphorus removal operations at different positions in the lake without damaging the original ecological system of the lake. The net basket 3 plants green plants for phosphorus removal, which utilizes the absorption of plants to reduce the phosphorus content in water bodies, and is a green and environmentally friendly phosphorus removal method. The filter tank 4 and the filter box 5 are arranged to further purify the lake water through different levels of filtration, improving the precision and effect of phosphorus removal. The mixing cylinder 7 and the matching mixing mechanism and the medicine supply pipe 9 can realize sufficient mixing of lake water and phosphorus removal liquid, ensuring the effect of chemical phosphorus removal. The booster mechanism in the filter tank 4 can ensure that the water flows smoothly into the filter box 5, improving the operation efficiency of the device.

[0036] In a further preferred embodiment of the present application, the mixing mechanism comprises: a water suction pipe 8 fixedly connected to the bottom of the mixing cylinder 7, the water outlet end of the water suction pipe 8 extending outside the assembly box 1 for extracting water from the lake; a rotating shaft 10 rotatably installed in the mixing cylinder 7 through a sealing bearing, the rotating shaft 10 being fixedly installed with an impeller 11; a flow divider 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 the present embodiment, the water suction pipe 8 fixedly connected to the bottom of the mixing cylinder 7 has its water outlet end extending outside the assembly box 1 to extract lake water from the lake and introduce the lake water into the mixing cylinder 7. The rotating shaft 10 installed in the mixing cylinder 7 rotates through a sealing bearing, and the fixed impeller 11 on the rotating shaft 10 rotates with the rotating shaft 10 to stir and mix the lake water entering the mixing cylinder 7 and the phosphorus removal liquid injected from the medicine supply pipe 9, so that the two are fully mixed. The flow divider in the mixing cylinder 7 serves to separate channels, optimizing the water flow path in the mixing cylinder 7 to enable the lake water and the liquid to flow and mix more orderly in the mixing cylinder 7. After sufficient mixing, the mixed liquid is delivered to the filter tank 4 for subsequent treatment through the water outlet pipe 12 fixedly connected to the top of the mixing cylinder 7, with the water outlet end of the water outlet pipe 12 extending into the filter tank 4.

[0038] The design of the mixing mechanism in the application further improves the phosphorus removal effect of the high-efficiency phosphorus removal device for lake water. Through a series of operations such as lake water extraction by the water suction pipe 8, impeller 11 stirring and mixing, flow distribution plate optimizing path, mixed liquid conveying by the water outlet pipe 12, etc., the lake water and the phosphorus removal liquid can be fully mixed in the mixing cylinder 7, the effect of chemical phosphorus removal is better, the phosphorus elements in the lake water are more effectively removed, and the phosphorus removal efficiency of the whole device is improved; the setting of the water suction pipe 8 can stably extract lake water from the lake, provide sufficient lake water to be treated for the mixing cylinder 7, and ensure the continuous operation 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 liquid, accelerate the mixing process of the two, and make the liquid more uniformly dispersed in the lake water, fully play the phosphorus removal role; the flow distribution plate can reasonably guide the water flow in the mixing cylinder 7, avoid the water flow from appearing turbulence or short circuit, etc., improve the uniformity and effect of mixing; the water outlet pipe 12 can successfully convey the uniformly mixed lake water to the filter tank 4, provide stable water flow supply for the subsequent filtration and purification step, and ensure the smooth operation of the whole phosphorus removal device.

[0039] In the further preferred embodiment of the application, the booster mechanism comprises: 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, the water outlet end of the connecting pipe 15 extending 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 pipe.

[0040] In this embodiment, when the lake water mixed in the mixing cylinder 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 conveyed through the connecting pipe 15 fixedly connected to the water outlet end of the water pump 14, the water outlet end of the connecting pipe 15 extending into the filter box 5, so as to send the water into the filter box 5; the first one-way valve 16 arranged on the connecting pipe 15 can control the opening and closing of the pipe. When the water pump 14 works to pump water, the first one-way valve 16 is opened to allow the 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 is closed to prevent the water in the filter box 5 from flowing back to the filter tank 4, and ensure the unidirectionality of the water flow direction;

[0041] The booster mechanism in the application further perfects the operation process of the high-efficiency phosphorus removal device for lake water bodies. Through water pumping by the water pump 14, water conveying by the connecting pipe 15, and control of the water flow direction by the first one-way valve 16, it can ensure that the water in the filter tank 4 smoothly and stably enters the filter box 5 for further purification treatment, improve the treatment efficiency of the device on lake water, and enhance the operation stability of the entire phosphorus removal device, so that the phosphorus elements in the lake water body can be more effectively removed, and the phosphorus removal effect is improved. The water pump 14, as the core component of the booster mechanism, can provide power for the water flow from the filter tank 4 to the filter box 5, ensure the flow speed and pressure of the water in the device, and enable the subsequent filtration and purification steps to be carried out smoothly. The connecting pipe 15 plays a role in stabilizing water conveying, accurately conveying the water pumped by the water pump 14 to the filter box 5, avoiding leakage and loss of water flow during conveying, and ensuring the continuity of the entire phosphorus removal 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 failure that may be caused by water backflow, improves the reliability and safety of the device, and also ensures that the water flows in the device according to the predetermined direction, improving the efficiency of the phosphorus removal operation.

When installing the phosphorus removal device, the assembly box 1 is first placed at a suitable position in the lake, then the steel wire rope 24 fixedly provided on the rope ring 23 is unfolded, and the sharp conical rod 25 connected with one end of the steel wire rope 24 is inserted into the soil of the lake shore, so that the assembly box 1 is stably fixed in the lake to prevent the device from moving randomly due to water flow and other factors. The provision of the connecting seat 22, the rope ring 23, the steel wire rope 24, and the sharp conical rod 25 on the assembly box 1 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, improving the flexibility and expandability of the device, and the number of devices can be adjusted according to the phosphorus removal needs of different lakes.

The filter material and the green plants are held in the planting basket 17, which can facilitate the management and replacement of the green plants and the filter material; when it is necessary to operate the planting basket 17, such as adding filter material, replacing green plants or checking the internal condition, the planting basket 17 can be taken out of the net basket 3 by gripping the symmetrically fixed handles on the planting basket 17, and after the operation is completed, the planting basket 17 is put back into the net basket 3;

[0047] In the present application, the detachable planting basket 17 and the matching handle are provided in the net basket 3, which further optimizes the phosphorus removal mode and operation convenience of the high-efficiency phosphorus removal device for lake water.
