[0029] The device includes:

[0030] A platform body 11, wherein the platform body 11 is disposed on one side of the lake 10;

[0031] The ecological isolation zone 20 is arranged inside the lake 10, the bottom of the ecological isolation zone 20 is connected to the lake bottom, and the top of the ecological isolation zone 20 is higher than the water surface; the ecological isolation zone 20 is connected to the platform body 11 and together separates the lake 10 into two areas, and the ecological isolation zone 20 is also provided with a connecting port 23 connecting the two areas of the lake 10;

[0032] A filtering structure is provided at the bottom of the platform body 11, and the filtering structure includes a filtering chamber, a pump body 24 is provided in the filtering chamber, and a water inlet 21 and a water outlet 22 are provided on the filtering chamber, and the positions of the water inlet 21 and the water outlet 22 are respectively located in two different areas of the lake 10;

[0033] The water in the lake 10 circulates through the water inlet 21, the water outlet 22, and the connecting port 23 under the action of the pump body 24, and is filtered through the filter bin during the circulation process.

[0034] Specifically, the ecological isolation zone 20 is an ecological isolation floating island, one end of the ecological isolation zone 20 is connected to the platform body 11, the other end of the ecological isolation zone 20 is arranged on the side opposite to the platform body 11, and the connecting port 23 is arranged at a position opposite to the platform body 11.

[0035] like Figure 1 The arrows indicate the schematic diagram of the circulation flow of the water body. The water body in the lake 10 is separated into two areas by the ecological isolation zone 20 and the platform body 11, and the water flow is pumped with less force by the pump body 24, so that the water flow in one area flows into the filter bin from the water inlet 21 and is filtered inside the filter bin and then discharged from the water outlet 22 of another area. Combined with the connecting port 23, the filtration and circulation of the water body are achieved at the same time. The connecting port 23 arranged on the opposite side can increase the circulation path of the water body, avoid short-circuit, and make the water body fluid. However, the fluidity of the water is still relatively small compared to the entire water body, realizing micro-flow.

[0036] The filter chamber includes a filter chamber 1 31, a filter chamber 2 32, a filter chamber 33, a clean water chamber 34 and a sewage chamber 35 which are arranged in sequence and connected to each other; the water inlet 21 is arranged on the filter chamber 1 31, and the water outlet 22 is arranged on the clean water chamber 34; the pump body 24 is arranged in the clean water chamber 34; and the water outlet end of the pump body 24 is connected to the water outlet 22 through the water outlet pipe 25; the filter chamber 1 31, the filter chamber 2 32, the filter chamber 33 and the clean water chamber 34 are connected to each other through an internal connecting port.

The end of the sewage main pipe 36 extends to the interior of the sewage chamber 35 . A sewage outlet 37 is provided at the bottom of the sewage chamber 35 .

[0038] Filter chamber 1 31, filter chamber 2 32 and filter chamber 3 33 perform multi-stage filtration on the water flow entering the water inlet 21 in sequence, removing different types of pollutants in the water step by step through multiple steps. Each step of filtration targets a specific type of pollutant, gradually improves the water quality, and ultimately achieves a high standard of purification effect.

[0039] The sewage main pipe 36 transports the sewage, impurities, etc. in the filter chamber 1 31 , the filter chamber 2 32 and the filter chamber 3 33 to the sewage chamber 35 , and finally discharges them through the sewage outlet 37 .

[0040] like Figure 3 As shown, Figure 3 Shown is a schematic structural diagram of a filtering structure in an embodiment.

[0041] The filter chamber 31 includes a rotating drum 311 which is rotatably arranged inside. A filter screen is arranged outside the rotating drum 311. The water inlet 21 is connected to the rotating drum 311. Water flows into the rotating drum 311, and the rotating drum 311 rotates to filter the water.

[0042] A pump body 315 and a plurality of high-pressure nozzles 312 arranged at intervals are also provided inside the filter chamber 31. The high-pressure nozzle 312 is provided above the drum 311. The water spraying end of the high-pressure nozzle 312 faces the filter screen of the drum 311. The water delivery end of the pump body 315 is connected to the high-pressure nozzle 312 through a water delivery pipe. A sewage branch pipe 314 is also provided at the bottom of the drum 311. The other end of the sewage branch pipe 314 extends to the sewage main pipe 36 at the bottom of the filter chamber 31; the high-pressure nozzle 312 sprays water to flush the filter screen; and the sewage is discharged into the sewage main pipe 36.

[0043] An ultraviolet sterilization lamp 313 is also provided inside the filter chamber 1 31 and at a position corresponding to the lower upper part of the drum 311;

[0044] Filter chamber 1 31 is a rotary drum microfiltration chamber, which plays a role of physical filtration. After the water flows into the interior of the drum 311, impurities and algae will be intercepted in the drum 311 through the rotation of the drum 311; the filtered water continues to flow into filter chamber 2 32; the pore size of the filter and the filtration accuracy are generally 0.1-50 microns, which can effectively remove fine suspended matter, colloids and microorganisms in the water, improve the clarity of the water quality, and achieve microfiltration.

[0045] The pump body 315 is a high-pressure water pump. The pump body 315 transports the water inside the filter bin 31 to the high-pressure nozzle 312. The high-pressure nozzle 312 flushes the filter screen outside the drum 311. The impurities flushed down flow through the sewage branch pipe 314 to the sewage main pipe 36, and are finally discharged from the sewage outlet 37 of the sewage bin 35.

[0046] The ultraviolet sterilization lamp 313 is an ultraviolet lamp, and its function is to sterilize and prevent the formation of bacterial film on the filter screen of the drum 311 and block the filter screen.

[0047] The second filter chamber 32 includes multiple rows of closely arranged brushes 321 disposed inside, and the brushes 321 are provided with a medium for anaerobic bacteria to attach;

[0048] The filter chamber 33 includes a fluidized bed filler 331 disposed inside and an aeration plate 332 disposed at the bottom end of the fluidized bed filler 331 .

[0049] Filter chamber 2 32 and filter chamber 3 33 play a role in microbial degradation. Through the brush 321 in filter chamber 2 32 and the fluidized bed filler 331 in filter chamber 33, anaerobic bacteria and aerobic bacteria reduce the concentration of organic matter in the water through biological oxidation and adsorption, remove part of the ammonia nitrogen, and degrade organic pollutants. The old bacterial film will fall off and deposit at the bottom, enter the main sewage pipe 36, and finally be discharged from the sewage outlet 37 of the sewage chamber 35.

[0050] The aeration plate 332 can not only provide oxygen for aerobic bacteria, but also increase the dissolved oxygen content in the water body and improve the self-purification ability of the water body.

[0051] Guide plates 322 are provided inside the second filter chamber 32 and the third filter chamber 33 and at positions corresponding to the internal connecting openings on both sides. The guide plates 322 allow water to flow through the brushes 321 and the fluidized bed filler 331 after entering the second filter chamber 32 and the third filter chamber 33.

[0052] The guide plate 322 guides the water flow when it flows through the second filter chamber 32 and the third filter chamber 33 , so that the flow path of the water flow passes through the brush 321 and the fluidized bed filler 331 .

[0053] An operating pipe 361 is also vertically arranged inside the sewage bin 35, one end of the operating pipe 361 extends upward from the platform body 11, and the other end of the operating pipe 361 is movably inserted into the terminal end of the sewage main pipe 36. When the operating pipe 361 is in the inserted state, the sewage main pipe 36 is closed, and when the operating pipe 361 is pulled out, the sewage main pipe 36 is opened to discharge sewage and the sewage is discharged to the outside from the sewage outlet 37.

[0054] The operating pipe 361 plays the role of opening and closing the sewage main pipe 36. The sewage flows from the end of the sewage main pipe 36 to the sewage outlet 37. The path is short and the sewage is discharged quickly.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
