Description

Technical Field

[0001] The present invention relates to the technical field of environmental water pollution control, and in particular to a multifunctional ecological floating island device and a purification method for lake water purification. Background Art

[0002] In recent years, my country's water pollution has become serious, and the problem of eutrophication has become increasingly prominent, especially in urban lakes. Water pollution not only seriously affects the living environment of surrounding residents, but also poses a major threat to the ecological security of the water environment. The key to solving the problem of eutrophication of lake water is to remove algae while reducing the content of nitrogen and phosphorus in the water.

[0003] At present, one of the main treatment methods for lake water management is water aeration technology. Its main principle is to increase the oxygen content of water and increase the fluidity of water flow through artificial aeration. This technology has low cost, wide application range, simple structure, and is not easy to cause secondary pollution. However, water aeration technology cannot directly remove algae in polluted water, and is mostly used for point source pollution control, with an extremely limited treatment range. Ultrasonic technology can effectively remove algae. It mainly uses shock waves, high temperature and high pressure, jets, etc. generated by mechanical force and cavitation effect to destroy the structural function and biological activity of algae cells. However, the diffusion effect of ultrasound will greatly weaken its treatment effect. Therefore, it is currently difficult to actually apply it to algae control in lake water. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional ecological floating island device and purification method for lake water purification. The device uses a water pump to provide power to form a large-scale water circulation, so that the water and air are fully mixed to oxygenate the water; at the same time, an ultrasonic generator placed near the water pipe generates ultrasonic waves to accurately remove algae.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is specifically as follows: a multifunctional ecological floating island device for lake water purification, including a base, a propeller, a solar power supply module, a water pumping aeration module and an ultrasonic purification module;

[0006] The base includes a floating plate and a plurality of frames, wherein the plurality of frames are evenly arranged on the upper side of the floating plate, and installation gaps are left between adjacent frames. Landscape plants can be planted on the floating plate, and the plant roots can also play a certain role in fixing phosphorus and nitrogen;

[0007] The solar power supply module includes a solar photovoltaic panel arranged on the upper surface of the frame and a battery pack arranged in the installation gap;

[0008] The propeller is arranged in the installation gap, and its lower end passes through the floating plate. The propeller can push the device to sail freely on the water surface and purify the water in the water area that needs to be purified;

[0009] The water-lifting aeration module is arranged in the base, and is used to circulate the water body, and fully mix the water body with air during the circulation process to increase oxygen for the water body;

[0010] The ultrasonic purification module is arranged in the installation gap, and its input end is connected to the output end of the water pumping aeration module, so as to remove algae in the circulating water body.

[0011] Furthermore, the battery packs are arranged in multiple groups and are evenly distributed in the installation gap.

[0012] Furthermore, the propeller is located below the battery pack.

[0013] Furthermore, the water-lifting aeration module includes a water pump and an air chamber, the input end of the water pump is connected to one end of a main water inlet pipe, the other end of the main water inlet pipe is connected to a bottom water inlet pipe and a side water inlet pipe, the output end of the water pump is connected to one end of a main water outlet pipe, the other end of the main water outlet pipe extends from the bottom of the air chamber into the air chamber, the water inlet of the bottom water inlet pipe is located below the water inlet of the side water inlet pipe, the water inlet of the bottom water inlet pipe mainly flows into the oxygen-deficient lake water in the lower layer, and the side water inlet mainly flows into the surface water containing floating algae, the water flows enter the main water inlet pipe from each water inlet and mix, flow to the upper air chamber and fully mix with the gas in the air chamber, a blower is also provided in the air chamber, the blower makes the water and air fully contact, and increases the dissolved oxygen content in the water, the air chamber is also connected to one end of a water pipe, the other end of the water pipe is connected to the input end of the ultrasonic purification module, the water body lifted to the upper air chamber by the water pump is water-lifting and aerated, and flows out from the water pipe after aeration

[0014] Furthermore, the end of the main water outlet pipe located inside the air chamber is a shower head structure, and its upper end is densely covered with water outlet holes. The water pump disperses the water pumped up through the main water outlet pipe into water droplets, thereby increasing the contact area between water and air.

[0015] Furthermore, the bottom water inlet pipe passes through the center of the floating plate away from one end of the main water inlet pipe and extends below it. Multiple side water inlet pipes are arranged, and the multiple side water inlet pipes are evenly arranged in the base. The side water inlet pipe passes through the side wall of the base away from one end of the main water inlet pipe, and the side water inlet pipes are distributed around the base.

[0016] Furthermore, the water inlets of the bottom water inlet pipe and the side water inlet pipe are both conical structures to avoid blockage.

[0017] Furthermore, the horizontal height of the ultrasonic purification module is lower than the horizontal height of the air chamber, so that the water in the air chamber will flow to the ultrasonic purification module due to gravity. The ultrasonic purification module includes a special box body arranged in the installation gap, and an ultrasonic generator is installed in the special box body. A spiral tube is wrapped around the outer surface of the ultrasonic generator. One end of the spiral tube is connected to the water pipe, and the other end extends out of the special box body.

[0026] 1. Based on the traditional water aeration technology, the present invention introduces an ultrasonic purification device to make up for the shortcoming that water aeration cannot directly destroy algae. By coupling the above technologies, a multifunctional ecological floating island device suitable for lake water purification is designed. The device uses a water pump to provide power to form a large-scale water circulation, so that the water and air are fully mixed to oxygenate the water; at the same time, an ultrasonic generator placed near the water pipe generates ultrasonic waves to accurately remove algae; the artificial floating island floats on the water surface, and landscape plants can be planted, and the plant roots can also play a certain role in fixing phosphorus and nitrogen.

[0027] 2. This device places the ultrasonic generator in the surrounding of the pipe. On the one hand, it can increase the contact area between the ultrasonic wave and the water in the pipe to achieve the purpose of fully removing algae. On the other hand, it can realize targeted algae removal in the water, solving the problem of poor algae removal effect caused by diffusion in traditional ultrasonic algae removal technology.

[0028] 3. The energy source of this device is solar energy, which solves the problems of poor mobility and limited functions of traditional artificial cable power supply. Compared with traditional water purification devices that require external power supply, consume more energy and are difficult to achieve automatic and continuous operation, this device uses solar energy to achieve energy self-sufficiency and realize automatic operation of the device.
