In some embodiments, the rubber rings are fixedly provided on an upper portion of the floating island box to improve the stability of the floating island box. In some embodiments, an even number of windows are arranged spaced apart around the floating island box, and are all communicated with an inside of the floating island box, the windows are all arranged at a same height on the floating island box, which facilitates the water intake and drainage; the tower cylinder is hollow and is fixedly arranged on a middle of a top end of the floating island box; a side of a bottom of the tower cylinder is fixedly provided with the compressed air storage tank, and a top of the tower cylinder is provided with the wind-driven air compressor; a side of the wind-driven air compressor is connected to the wind-driven blade via a transmission mechanism; a first connecting pipe and a second connecting pipe are provided in the tower cylinder; one end of the first connecting pipe is communicated with the wind-driven air compressor, and the other end of the first connecting pipe is communicated with the compressed air storage tank; one end of the second connecting pipe is communicated with the compressed air storage tank, and the other end of the second connecting pipe is extended into the floating island box for aeration.

The vertical shaft drives the connecting rod to generate relative motion between the first piston and the first cylinder of the wind-driven air compressor, thereby generating compressed air. The generation of compressed air does not require external electricity and fuel, which is energy-saving and environmentally friendly. The compressed air in the compressed air storage tank is used to support the rotation, movement and biochemical aeration of the bio-ecological micro-power floating island device.

In an embodiment, an aeration pipe, a plurality of biological carrier modules, a plurality of plant modules and a fixed frame are provided in the floating island box; the plurality of plant modules and the plurality of biological carrier modules are arranged on the fixed frame; the aeration pipe is provided horizontally at a bottom of the floating island box, and the aeration pipe is communicated with an end of the second connecting pipe away from the compressed air storage tank. The floating island box and the biological carrier modules and plant modules arranged therein together constitute a biochemical reaction tank for bio-ecological processing of sewage. In some embodiments, microorganisms, such as bacteria and fungi, and microscopic animals, such as protozoa and metazoans, are attached to the biological carrier modules and plant modules for growing and proliferation, thereby forming an activated sludge-biofilm. When exposed to the bio-film, the organic pollutants in the black and odorous water body are consumed by the microorganisms on the bio-film as nutrients, facilitating the purification of the black and odorous water body and the growth of the microorganisms. The biological carrier modules and plant modules are used as carriers for the microorganisms, and a highly diversified ecosystem can be constructed in the floating island box, which facilitates enhancing the removal effect of pollutants in the black and odorous water body based on the metabolism of microorganisms, aquatic plants and aquatic animals in each sub-ecosystem.

Microorganisms mainly experience an attached growth on the carrier, which can reduce the concentration of suspended sludge, lower the production of sludge, and increase the oxygen transfer efficiency At the same time, it can significantly raise the equivalent sludge concentration of the biochemical reaction tank, thereby improving the efficiency of sewage treatment. In the case of meeting the same effluent water quality standard, the device provided herein significantly reduces the hydraulic residence time in the biochemical reaction tank and diminishes the size of the floating island box, and has smaller floor space. In short, the microorganisms attached to biological carrier modules and the roots of the plants in the plant modules together form a bio-film, which allows for a higher density of sludge, facilitating strengthening the adaptability to the impact load of water to form a stable and efficient sewage treatment system. The roots of the plant modules can also take in nitrogen and phosphorus from the black and odorous water body to promote the removal of nitrogen and phosphorus. The aeration in the floating island box is performed using compressed air generated by the wind-driven air compressor without additional electricity and fuel, allowing for less energy consumption.

In an embodiment, the bio-ecological micro-power floating island device further comprises a plurality of third connecting pipes and a plurality of air propellers; wherein the plurality of air propellers are provided spaced apart around the floating island box; each of the plurality of air propellers is connected to one of the plurality of third connecting pipes; an end of each of the plurality of third connecting pipes away from the air propeller is communicated with the compressed air storage tank; each of the plurality of third connecting pipes is provided with a valve; each of the plurality of air propellers comprises a second cylinder, a second piston, a crankshaft and a propeller blade; the second piston is slidably provided in the second cylinder; an end of the second cylinder is communicated with the third connecting pipes, a side of the second piston away from the third connecting pipes is connected to the crankshaft; the propeller blade is arranged spaced apart on an end of the crankshaft away from the second piston; and the compressed air in the compressed air storage tank is transported to the air propellers through the third connecting pipes. The working principle of the air propeller is that compressed air pushes the piston to run in the cylinder to drive the crankshaft to rotate, and the rotation of the crankshaft further drives the propeller blades to rotate, thereby driving the bio-ecological micro-power floating island device to rotate or move. In some embodiments, the propeller blade of each of the air propellers rotates together with the crankshaft to suck water from the suction surface of the propeller blade and discharge water from the discharge surface, which enables that the floating island box is pushed by the reaction force of water to rotate or move. Whether the air propeller is under operation or out of operation is determined by the valve on individual third connecting pipes.

In an embodiment, the floating island box is cylindrical, which facilitates improving the resistance to external impact and structural stability. Each of the windows has a tubular structure with two ends opened which is formed by a guide plate; an even number of windows are arranged spaced apart on a circumference of the floating island box; guide plates of the windows at one side of the circumference of the floating island box are arranged obliquely and clockwise with respect to the circumference of the floating island box; and guide plates of the windows at the other side of the circumference of the floating island box are arranged obliquely and counterclockwise with respect to the circumference of the floating island box. Based on the above arrangement, a direction of the guide plates of the windows at one side of the circumference of the floating island box is opposite to that of the guide plates of the windows at the other side of the circumference of the floating island box, always ensuring that the windows at one side are used for water intake and the windows at the other side are used for water drainage.

In an embodiment, a cross section inside each of the windows is further provided with an insert plate which is movable vertically. The insert plate fits the cross section of the windows in shape, so that the cross section of the windows can be blocked when the insert plate is completely lowered; the windows are unblocked when the insert plate is placed above the windows; the cross section of the windows is partially blocked when the insert plate is partly lowered. As a consequence, the water intake and drainage can be adjusted, thereby controlling the residence time of the black and odorous water in the floating island box. For a black and odorous water body with extremely poor water quality, an unblocked area of the window is adjusted to be smaller to extend the residence time of the black and odorous water in the floating island box, thus enhancing the purification effect. On the contrary, for a black and odorous water body with relatively good water quality, the unblocked area of the window is adjusted to be larger to shorten the residence time of the black and odorous water in the floating island box, allowing for improved purification efficiency.

In an embodiment, the air propellers are rotatably connected to an outside of the floating island box to adjust the arrangement angle of the air propellers. In some embodiments, the air propellers are connected to the outside of the floating island box through a pin. The angle between individual air propellers and the tangent of the outer circumference of the floating island box can be manually adjusted according to the rotation or movement of the floating island box, and then fixed by a pin after adjustment. When it is required to rotate the bio-ecological micro-power floating island device, each of the air propellers is arranged at an angle of 300-450 with a tangent of the outer circumference of the floating island box to drive the floating island box to rotate. During the rotation of the floating island box, the arrangement angles of the guide plates of the windows on the two semicircumferences of the floating island box are opposite, so that the following effect can be obtained without any external force according to the principle of fluidics: the windows at one side of the circumference are used for water intake and the windows at the other side of the circumference are used for water drainage. When it is required to move the bio-ecological micro-power floating island device horizontally, each of the air propellers is arranged at an angle of 900 with a tangent of the outer circumference of the floating island box, and at the same time, one of the air propellers is turned on according to the moving direction, and other air propellers are all shut off by closing the valves on the corresponding third connecting pipes, achieving the horizontal motion of the floating island box. In addition, the compressed air released by the air propellers can be also used for the biochemical aeration of the black and odorous water body.

In an embodiment, a plant in each of the plant modules is an emerged plant. The biological carrier modules and the plant modules are arranged in the floating island box, thereby optimizing the performance of the biological module. Each of the biological carrier modules comprises a carrier frame, a filler layer and a fastener, where the filler layer is fixedly provided in the carrier frame by the fastener, and the filler layer is a curtain-type fiber filler layer. In some embodiments, the curtain-type fiber filler layer is a curtain-type ecological fiber layer. After hydrophilic treatment, a large number of micro pores are formed on the fiber surface, which leads to a larger specific surface area, facilitating the adhesion of microorganisms to the film. The curtain-type ecological fiber layer is woven tightly to loosely from the inside to the outside, and based on this weaving manner, an anaerobic, facultative and aerobic micro-environment is created in the curtain-type fiber filler layer, so that it is suitable for the simultaneous nitrification and denitrification (SND), facilitating improving the nitrogen-and phosphorus-removing performance of the system. Each of the plant modules sequentially comprises a planting basket, a sieve, a substrate and the plant from the outside to the inside. In some embodiments, the planting basket is an external frame, in which the substrate is provided, and the plant is cultivated in the substrate. The sieve is provided above the substrate to fix the substrate to avoid the loss of the substrate. The substrate is ceramsite or the like. In this application, the emerged plant is embedded in the plant modules to construct an ecological system suitable for the growth and reproduction of microorganisms, which can not only partially remove the organics in the black and odorous water body through plant growth, but also construct auxiliary biological carriers through plant roots, thereby reducing the residual sludge and the odor generated in the treatment of the black and odorous water body and improving the landscape environment. In some embodiments, the emerged plant is reed, Noha angustifolia, cress, Zizcznia latifolia, lotus, cattail, arrowhead, etc. The root system of the plant modules can take in the nitrogen and phosphorus from the black and odorous water body to promote the removal of nitrogen and phosphorus.

Compared with the prior art, this application has the following advantages.

1. The device provided herein has advantages of desirable stability, high efficiency, small space occupation, low energy consumption and beautiful landscape when applied to the treatment of urban black and odorous water bodies, which conforms to the national development concept of green treatment.

In this application, the air compressor is driven by natural wind energy, so there is no generation of waste gas and no need of additional electricity and fuel, rendering the device energy-saving, environmentally friendly and safe. In addition, the compressed air released by the air propeller can be also applied to the biochemical aeration of the black and odorous water.

3. The device provided herein achieves the bio-ecological processing of waste water through the provision of biological carrier modules and plant modules.

The bio-film adheres to the artificial filler and a dissolved oxygen gradient is generated in the bio-film, which facilitates the synchronous nitrification and denitrification. This application has an ammonia nitrogen removal rate of 95% or more, and a total nitrogen removal rate of 85% or more.

In some embodiments, the emerged plant is reed, lipha angttstifolia, cress, Zizcmia lotus, cattail, arrowhead, etc. The root system of the plant modules 10 can take in nitrogen and phosphorus from the black and odorous water to promote the removal of nitrogen and phosphorus.

Embodiment 3 As shown in Figs. 1-3, a bio-ecological micro-power floating island device used in the method for treating black and odorous water bodies is provided, which includes a floating island box 1, a plurality of rubber rings 2, a plurality of windows 3 for water intake and drainage; a wind-driven blade 5, a wind-driven air compressor 6, a compressed air storage tank 7 and a tower cylinder 11. The plurality of rubber rings 2 are arranged around the floating island box 1 to provide buoyancy to enable the floating island box 1 to float stably on the black and odorous water, thereby playing a role as a sewage processing facility on the black and odorous water body. In some embodiments, the rubber rings 2 are fixedly provided on an upper portion of the floating island box 1 to improve the stability of the floating island box 1. In some embodiments, an even number of the windows 3 are arranged spaced apart around the floating island box 1, and are all communicated with an inside of the floating island box 1. The windows 3 are all arranged at a same height on the floating island box 1, which facilitates the water intake and drainage. The tower cylinder 11 is hollow and is fixedly arranged on a middle of a top end of the floating island box I. A side of a bottom of the tower cylinder 11 is fixedly provided with the compressed air storage tank 7, and a top of the tower cylinder 11 is provided with a wind-driven air compressor 6. A side of the wind-driven air compressor 6 is connected to the wind-driven blade 5 via a transmission mechanism. A first connecting pipe 12 and a second connecting pipe 13 are provided in the tower cylinder 11. One end of the first connecting pipe 12 is communicated with the wind-driven air compressor 6, and the other end of the first connecting pipe 12 is communicated with the compressed air storage tank 7. One end of the second connecting pipe 13 is communicated to the compressed air storage tank 7, and the other end of the second connecting pipe 13 is extended into the floating island box 1 for aeration. The wind-driven blade 5 arranged on a top of the tower cylinder 11 drives the wind-driven air compressor 6 through the transmission mechanism to generate compressed air, and the compressed air is stored in the compressed air storage tank 7. The wind-driven air compressor 6 is driven by natural wind energy to work. In some embodiments, the transmission mechanism includes a horizontal shaft, a first bevel gear, a second bevel gear and a vertical shaft. One end of the horizontal shaft is provided with the wind-driven blade 5, and the other end of the horizontal shaft is horizontally connected to the first bevel gear. The first bevel gear is engaged with the second bevel gear. The second bevel gear is vertically connected to the vertical shaft, and an end of the vertical shaft away from the second bevel gear is connected to the wind-driven air compressor 6. The wind-driven air compressor 6 includes a connecting rod, a first piston, and a first cylinder. The one end of the connecting rod is connected to the vertical shaft, and the other end of the connecting rod is connected to the first piston. The first piston is slidably arranged in the first cylinder, and an end of the first cylinder away from the vertical shaft is connected to an end of the first connecting pipe 12. The wind-driven blade 5 is driven by the wind to perform circular motion around the horizontal shaft and drive the first bevel gear, the second bevel gear and the vertical shaft to rotate. The vertical shaft drives the connecting rod to generate relative motion between the first piston and the first cylinder of the wind-driven air compressor, thereby generating compressed air. The generation of compressed air does not require external electricity and fuel, which is considered energy-saving and environmentally friendly. The compressed air in the compressed air storage tank 7 is used to support the rotation, movement and biochemical aeration of the bio-ecological micro-power floating island device.

In some embodiments, the bio-ecological micro-power floating island device further includes a plurality of third connecting pipes 15 and a plurality of air propellers 4. The plurality of the air propellers 4 are provided spaced apart around the floating island box 1. Each of the air propellers 4 is connected to one of the plurality of third connecting pipes 15, and an end of each of the plurality of third connecting pipes 15 away from the air propeller is communicated with the compressed air storage tank 7. Each of the plurality of third connecting pipe 15 is provided with a valve. Each of the plurality of air propellers 4 includes a second cylinder, a second piston, a crankshaft and a plurality of propeller blades, and the second piston is slidably provided in the cylinder. An end of the second cylinder is communicated with the third connecting pipes 15. A side of the second piston away from the third connecting pipes 15 is connected to the crankshaft, and the propeller blades are arranged spaced apart on an end of the crankshaft away from the second piston. The compressed air in the compressed air storage tank 7 is transported to the air propellers 4 through the third connecting pipes 15. The working principle of the air propeller 4 is that compressed air pushes the second piston to run in the cylinder to drive the crankshaft to rotate, and the rotation of the crankshaft further drives the propeller blades to rotate, thereby driving the bio-ecological micro-power floating island device to rotate or move. In some embodiments, the propeller blades of each of the air propellers 4 rotate together with the crankshaft to suck water from the suction surface of the propeller blade and discharge water from the discharge surface, which enables that the floating island box 1 is pushed by the reaction force of water to rotate or move. Whether the air propeller is under operation or out of operation is determined by the valve on individual third connecting pipes. The principle based on which the transmission mechanism drives the wind-driven air compressor 6 to produce compressed air is just opposite to the working principle of the air propeller 4. Specifically in the former case, the wind is used to produce compressed air; while in the latter case, the compressed air is used to produce power. These devices can be selected from the prior art.

In an embodiment, the floating island box 1 is cylindrical, which facilitates improving the resistance to external impact and structural stability The floating island box 1 can also adopt a cuboid structure. Each of the windows 3 has a tubular structure with two ends opened which is formed by a guide plate 16. An even number of windows 3 are arranged spaced apart on a circumference of the floating island box I. Guide plates 16 of the windows 3 at one side of the circumference of the floating island box 1 are arranged obliquely and clockwise with respect to the circumference of the floating island box I; and guide plates 16 of the windows 3 at the other side of the circumference of the floating island box 1 are arranged obliquely and counterclockwise with respect to the circumference of the floating island box 1. Based on the above arrangement, a direction of the guide plates 16 of the windows 3 at one side of the circumference of the floating island box 1 is opposite to that of the guide plates 16 of the windows 3 at the other side of the circumference of the floating island box 1, always ensuring that the windows 3 at one side are used for water intake and the windows 3 at the other side are used for water drainage. As shown in Figs. 8-10, the single window 3 can be a cuboid formed by four guide plates 16, or a cylinder formed through the surrounding of one guide plate 16, or a polyhedron formed by five guide plates 16 A cross section inside each of the windows 3 is further provided with an insert plate 17 which is movable vertically The insert plate 17 fits the cross section of the windows 3 in shape. As shown in Fig. 8, the window 3 is blocked when the insert plate 17 is completely lowered. As shown in Fig. 10, the window 3 is unblocked when the insert plate 17 is placed above the windows 3. As shown in Fig. 9, the cross section of the window 3 is partially blocked when the insert plate 17 is partly lowered. As a consequence, the water intake and drainage can be adjusted, thereby controlling the residence time of the black and odorous water body in the floating island box I. For a black and odorous water body with extremely poor water quality, an unblocked area of the window 3 is adjusted to be smaller to extend the residence time of the black and odorous water in the floating island box 1, thus enhancing the purification effect. On the contrary, for a black and odorous water body with relatively good water quality, the unblocked area of the window 3 is adjusted to be larger to shorten the residence time of the black and odorous water in the floating island box 1, allowing for improved purification efficiency.

In some embodiments, four windows 3 are arranged spaced apart around the floating island box 1, and are communicated with the floating island box 1. Four air propellers 4 are arranged spaced apart around the floating island box 1, each of which is connected to a third connecting pipe 15. An end of the third connecting pipe 15 away from the air propellers 4 is communicated with the compressed air storage tank 7.

The wind-driven air compressor 6 includes a connecting rod, a first piston, and a first cylinder.

The first piston is slidably arranged in the first cylinder, and an end of the first cylinder away from the vertical shaft is connected to an end of the first connecting pipe 12. The wind-driven blade 5 is driven by the wind to perform circular motion around the horizontal shaft and drive the first bevel gear, the second bevel gear and the vertical shaft to rotate. The vertical shaft drives the connecting rod to generate relative motion between the piston and the cylinder of the wind-driven air compressor, thereby generating compressed air. The generation of compressed air does not require external electricity and fuel, which is considered energy-saving and environmentally friendly. The compressed air in the compressed air storage tank 7 is used to support the rotation, movement and biochemical aeration of the bio-ecological micro-power floating island device.

In some embodiments, the bio-ecological micro-power floating island device further includes a plurality of third connecting pipes 15 and a plurality of air propellers 4. The plurality of the air propellers 4 are provided spaced apart around the floating island box 1. Each of the air propellers 4 is connected to one of the plurality of third connecting pipes 15, and an end of each of the plurality of third connecting pipes 15 away from the air propeller is communicated with the compressed air storage tank 7.

A side of the second piston away from the third connecting pipes 15 is connected to the crankshaft, and propeller blades are arranged spaced apart on an end of the crankshaft away from the second piston. The compressed air in the compressed air storage tank 7 is transported to the air propellers 4 through the third connecting pipes 15. The working principle of the air propeller 4 is that compressed air pushes the second piston to run in the cylinder to drive the crankshaft to rotate, and rotation of the crankshaft further drives the propeller blades to rotate, thereby driving the bio-ecological micro-power floating island device to rotate or move. The propeller blades of each of the air propellers 4 rotate together with the crankshaft to suck water from the suction surface of the propeller blade and discharge water from the discharge surface, which enables that the floating island box 1 is pushed by the reaction force of water to rotate or move. Whether the air propeller is under operation or out of operation is determined by the valve on individual third connecting pipes.

In an embodiment, the floating island box 1 is cylindrical, which facilitates improving the resistance to external impact and structural stability The floating island box 1 can also adopt a cuboid structure. Each of the windows 3 has a tubular structure with two ends opened which is formed by a guide plate 16. An even number of windows 3 are arranged spaced apart on a circumference of the floating island box 1. Guide plates 16 of the windows 3 at one side of the circumference of the floating island box 1 are arranged obliquely and clockwise with respect to the circumference of the floating island box 1; and guide plates 16 of the windows 3 at the other side of the circumference of the floating island box 1 are arranged obliquely and counterclockwise with respect to the circumference of the floating island box 1. Based on the above arrangement, a direction of the guide plates 16 of the windows 3 at one side of the circumference of the floating island box 1 is opposite to that of the guide plates 16 of the windows 3 at the other side of the circumference of the floating island box 1, always ensuring that the windows 3 at one side are used for water intake and the windows 3 at the other side are used for water drainage. As shown in Figs. 8-10, the single window 3 can be a cuboid formed by four guide plates 16, a cylinder formed by the surrounding of one guide plate 16, or a polyhedron formed by five guide plates 16.

The air propellers 4 are rotatably connected to an outside of the floating island box 1 to adjust the arrangement angle of the air propeller 4. The air propellers 4 are connected to the outside of the floating island box through a pin. The angle between individual air propellers 4 and the tangent of the outer circumference of the floating island box 1 can be manually adjusted according to the rotation or movement of the floating island box 1, and then fixed by a pin after adjustment. As shown in Figs. 4-5, when it is required to rotate the bioecological micro-power floating island device, each of the air propellers 4 is arranged at an angle of 30°-45°, such as 45°, with a tangent of the outer circumference of the floating island box 1 to drive the floating island box 1 to rotate. During the rotation of the floating island box 1, the arrangement angles of the guide plates of the windows 3 on the two semicircumferences of the cylindrical floating island box 1 are opposite, so that the following effect can be obtained without any external force: the windows 3 at one side of the circumference are used for water intake and the windows 3 at the other side of the circumference are used for water drainage. As shown in Figs. 6-7, when it is required to move the bio-ecological micro-power floating island device horizontally, each of the air propellers is arranged at an angle of 900 with a tangent of the outer circumference of the circular floating island box I. At the same time, one of the air propellers 4 is turned on according to the moving direction, and the other air propellers 4 are all shut off by closing the valves on the corresponding third connecting pipe 15, achieving the horizontal motion of the floating island box 1.
