Description

Technical Field

[0001] The invention relates to the technical field of water body treatment devices, and in particular to a lake and reservoir water eutrophication treatment device. Background Art

[0002] The lake and reservoir water eutrophication control device is a high-tech equipment designed to solve the problem of water eutrophication. Eutrophication refers to the excessive amount of nutrients such as nitrogen and phosphorus in the water, which leads to the massive reproduction of algae, thereby reducing the oxygen in the water and affecting the ecological balance. The control device usually adopts a variety of technical means, including a combination of physical, chemical and biological methods, to achieve the purpose of reducing the nutrient concentration of the water body. The equipment removes excess nitrogen and phosphorus elements in the water through pretreatment, aeration, sedimentation and other links. This control device not only improves the water quality, but also restores the ecological function of the lake and reservoir, and provides a good living environment for aquatic organisms. At the same time, the whole system is simple to operate and easy to maintain. It is an effective means to control water eutrophication and is widely used in various lakes, reservoirs and wetland protection projects.

[0003] After searching, the Chinese patent number CN221440379U discloses a lake and reservoir eutrophication control device. The impeller cylinder is provided with impeller blades on its surface, which will rotate under the drive of water flow and drive the pressure rod and spring rod to rotate. A spring is fixed on the surface of the spring rod, and one end of the spring is fixed to the surface of the pressure rod. Under normal conditions, the spring will push the pressure rod to move forward and keep it upright. A spring is installed at the bottom of the elastic plate, and the bottom of the spring is fixed to the top of the opening and closing plate. The opening and closing plate is limited by the frame, and a long rod is fixed on the side of the opening and closing plate. The pressure rod will move the long rod and then bend and rebound, and then continue to circulate, so that the opening and closing plate opens and closes to inhale water flow to mix the materials and finally spray them to realize the spraying operation. This process does not require electric power drive, saves energy and spreads materials in multiple areas. The materials are driven by the movement of the lower water flow to the upper water flow, which is relatively uniform. Compared with the prior art, the Chinese patent number CN221440379U solves the problem that the diverging device of the prior art is arranged in the upper area of ​​the water flow for stability, which will result in the treatment material being unable to effectively purify the water body of the lower water flow, and the equipment of the prior art needs to use a driving source to release the material, which consumes a lot of energy.

[0004] However, in actual use of the above device, the device treats water bodies by adding passivating agents to promote the precipitation of phosphates in the water body. However, the treatment method is relatively simple, and the pollution sources are complex, resulting in poor treatment effects. In addition, the dissolved oxygen content in the water body is difficult to increase during the treatment process, which is not convenient for ecological restoration in the water body. Therefore, a lake and reservoir water eutrophication treatment device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] A feeding mechanism is provided at the upper end of the stepped base 1, and a passivating agent can be fed into the water body. Ecological flow mechanisms are provided on both sides of the stepped base 1, and the ecological flow mechanisms can degrade organic pollutants and other substances in the water body flowing into the mechanism from both sides of the stepped base 1;

[0036] Two adjustment mechanisms are arranged inside the drain port 4, and the adjustment mechanisms can drive the movable baffle 16 arranged at the upper end of the drain port 4 to move, so as to adjust the flow area of ​​the drain port 4. The adjustment mechanism includes a control housing 15 fixedly connected to the inside of the drain port 4, and a first motor 17 is arranged at the bottom of the control housing 15. An adjustment component is arranged at the output end of the first motor 17, and the adjustment component includes a first screw rod 18 arranged at the output end of the first motor 17, and the first screw rod 18 is rotatably connected to the control housing 15, and the first screw rod 18 is threadedly connected with the movable baffle 16, and the movable baffle 16 is slidably connected to the drain port 4. The movable baffle 16 is rotatably connected to one side of the control housing 15 with two rotating wheels 19, and a limit rod 20 is arranged at the middle position of the two rotating wheels 19, and the limit rod 20 is fixedly connected to the control housing 15;

[0037] The ecological flow mechanism includes a flow shell 2 fixedly connected to the stepped base 1, a sedimentation layer 5 is arranged on the upper part of the flow shell 2, a filter layer 6 is arranged at the lower end of the sedimentation layer 5, a purification layer 7 is arranged at the lower part of the filter layer 6, and a submerged flow exchange layer 9 is arranged at the lower part of the purification layer 7. The filter layer 6 and the purification layer 7 are connected through a flow hole 8, and the purification layer 7 and the submerged flow exchange layer 9 are also connected through the flow hole 8. A filter tank 10 is arranged inside the flow hole 8.

[0038] In this embodiment, the stepped base 1 can be set at the junction of the upstream and downstream of the waterway when in use, and the water flow from the upstream falls into the downstream step by step through the upper end of the stepped base 1. During the falling process, the water flow will fall into the energy dissipation pool 12 through the drop wall 11 for many times.
