The automatic opening 3 is provided with a cutting knife 4 to prevent the opening from being blocked due to the overlarge volume of the suspended matters 22. Fig. 2 is a schematic view of a cutting knife, which mainly comprises a fixing rod 24, a transmission rod 25, a tabletting device 26, a gasket 27, a blade protector 28, a movable blade 29 and a knife bar 30. The sheeting 26 and the gasket 27 fix a cutter bar 30 and a blade protector 28 on the fixed rod 24, the cutter bar 30 is provided with a movable blade, and the cutting knife 4 works under the action of the transmission rod 25. The cutting knife 4 of the invention adopts a reciprocating cutting knife, and the principle is that the space motion of a transmission rod 25 is changed into the rotation of a fixed rod 24 of a shifting fork, thereby achieving the reciprocating motion. The blade guard 28 of the reciprocating cutter divides the target floating objects 22 into a plurality of parts and delivers the parts to the movable blade 29, and the movable blade 29 pushes the target to the fixed part of the blade guard 28 for cutting in the reciprocating motion.
The eutrophic water body and the suspended matters reach the separation system of the invention after the primary treatment of the collection system. The separation system comprises a solid-liquid filter screen 15, a DATA-52 series diffused silicon pressure transmitter 23, a nitrogen-phosphorus synchronous adsorbent steel filter screen 14, a rotating disk 18 and a centrifugal barrel 20, wherein a diffused silicon pressure sensor 23 is arranged below the first layer of the solid-liquid filter screen 15, a water body is filtered by the solid-liquid filter screen 15, suspended matters 22 in the water body are left in the centrifugal barrel 20, when the gravity reaches the standard, the diffused silicon pressure sensor 23 transmits signals to an automatic opening 3, and an opening door 6 is closed by electric signals transmitted by the opening.
The DATA-52 series diffused silicon pressure transmitter 23 is fabricated by packaging a silicon piezoresistive pressure sensitive element with isolation in a stainless steel housing. By means of the piezoresistive effect principle, the pressure of the measured medium acts directly on the stainless steel or ceramic diaphragm of the sensor to produce small displacement in direct proportion to the medium pressure, so that the resistance of the sensor changes, and the electronic circuit detects the change and converts to output one standard measuring signal corresponding to the pressure. The sensed liquid or gas pressure is converted into a standard electric signal to be output outwards, the opening and closing of the opening and closing door 6 are controlled by collecting the electric signal, the condition is collected by the monitoring device, and the collected floating objects 22 are processed in time.
After the water body is filtered by the solid-liquid filter screen 15, the larger suspended matters 22 in the water are effectively treated. And then, the rotating disc 18 rotates at a high speed to generate centrifugal force, water and the barrel wall of the centrifugal barrel 20, the suspended matters 22 and the barrel wall of the water, the suspended matters 22 and the barrel wall of the centrifugal barrel 20 rub against each other, and the water in the water body flows downwards through the nitrogen-phosphorus synchronous adsorbent steel filter screen 14 of the second layer of filter screen under the action of the centrifugal force to carry out secondary filtration, so that the water and the suspended matters 22 in the water body are further separated. The nitrogen and phosphorus synchronous adsorbent steel filter screen 14 adsorbs N, P element once and controls the release of nitrogen and phosphorus while filtering out the suspended matters 22, and can also effectively prevent the system from being blocked.
The suspended matters 22 in the water body are filtered by the solid-liquid filter screen 15 and the nitrogen-phosphorus synchronous absorbent steel filter screen 14 for the second time, and the water body reaches the standard of being discharged into the composite filling layer 8 for the next treatment.
The water body from the centrifuge bucket 20 to the purification system needs to be driven by the submersible pump 17. The water body enters intensively through a water inlet 13 of a submersible pump 17 in the middle of a rotating disc 18, is conveyed to a water pump outlet 10 through a water conveying pipe 11 under the conveying action of the submersible pump 17 and then flows into the composite filling layer 8.

The water body reaches the backflow prevention device 31 in the composite filling layer 8 device through the submersible pump 17 and is conveyed to the lower hole plate 32 through the water conveying pipe 11. After the power provided by the submersible pump 17, the water body passes through the lower fiber medium 33 and then is purified through the ceramsite 34, the diatomite-zeolite composite agent 35 and the bamboo filament filler 36.

The bamboo filament filler 36 can form some scattered bamboo filament fibers and a biological membrane structure, and the net catching effect on macromolecular organic particles and inorganic particles is enhanced. The water body purified by the ceramsite 34, the diatomite-zeolite complexing agent 35 and the bamboo filament filler 36 passes through the upper fiber medium 37 and the upper pore plate 38, and the nitrogen and phosphorus pollutants in the water are finally purified by the combined plant roots 39 of various plants on the upper pore plate. The water finally exits the invention through outlet 40. The effect of the combination of various plants on removing nitrogen and phosphorus pollutants in water is better than that of planting a single plant. By applying the technical principle of the biological floating island, on one hand, the device is shown in the way that a root system net with dense plants and large surface area is utilized to adsorb a large amount of N, P elements in a water body, and on the other hand, the device inhibits the photosynthesis of algae by shading sunlight to prevent the overgrowth of phytoplankton. Meanwhile, dense aquatic plants are planted above the device and can be selected according to the local natural environment. Generally, the plants include emergent aquatic plants such as cress, water hyacinth, iris, thalictrum and yellow flag, and submerged plants such as watermifoil, waterweed and goldfish.
