Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of water purification ships, and particularly relates to an integrated water purification ship of photosynthetic plants and functional microorganisms. Background Art
[0002] In some regions, the water ecosystem will experience eutrophication due to the intake of excessive inorganic nutrients. Microorganisms can effectively degrade nitrogen and phosphorus elements in water through ammonification and denitrification of nitrogen and decomposition of phosphorus. By carrying immobilized carrier microorganisms on a ship, nitrogen, phosphorus and other pollutants in water can be quickly removed, meeting the surface water class III standard or above, and avoiding the occurrence of eutrophication.

And the two ends of the support shaft 16 are respectively fixedly connected to one end of the two coil springs 22. Among them, a blower 23 is installed on the purification hull 1. The output end of the blower 23 is communicated with the glass cover 2. And a blast filter plate 24 is detachably installed inside the output end of the blower 23.
[0064] Correspondingly, a purification mechanism is further included. The purification mechanism includes: a microorganism fixed emitter 25, a purification pipe 26, an oxygen supply pipe 27, a conveyor 28, and a feeding pipe 29. The microorganism fixed emitter 25 is installed in one of the openings 1. A plurality of purification pipes 26 are fixedly installed in the microorganism fixed emitter 25. And both ends of the plurality of purification pipes 26 are sealed by wire meshes. The glass cover 2 is communicated with the plurality of purification pipes 26 through the oxygen supply pipe 27.

The output end of the conveyor 28 is communicated with the plurality of purification pipes 26 through the feeding pipe 29.
[0065] It should be noted that by installing a water inlet pipe and a water outlet pipe, the water in the glass cover 2 can be circulated. And one-way valves are installed on the water inlet pipe, the water outlet pipe, the feeding pipe 29, and the oxygen supply pipe 27. And a propeller and a controller are installed on the purification hull 1.
[0066] It should also be noted that the conveyor 28 mentioned above can select a corresponding water pump or other equipment that can perform transportation according to the viscosity of the microbial gel.
[0067] In summary, the working principle of the integrated water purification ship of photosynthetic plants and functional microorganisms is as follows: insert the photosynthetic plants into the grid plate 4 and the sponge 5, then place the purification hull 1 into the water so that the microbial fixed emitter 25 is immersed in the water. At this time, water will enter the glass cover 2 through the water inlet pipe, immersing the root systems of the photosynthetic plants in the water. And the water in the glass cover 2 can be discharged through the water outlet pipe, enabling the water in the glass cover 2 to flow. Then, control the driving direction of the purification hull 1 through the propeller. Then, the photosynthetic plants in the glass cover 2 perform photosynthesis to produce oxygen, and the produced oxygen enters the purification pipeline 26 through the oxygen delivery pipe 27. Then, start the conveyor 28, and through the conveyor 28, the microbial gel in the storage box body is conveyed into the multiple purification pipelines 26 through the material delivery pipe 29, and the metabolic rate and degradation efficiency of the microorganisms are increased by the oxygen produced by the photosynthetic plants. Then, the water in the microbial fixed emitter 25 is purified by the microbial gel, and the microbial fixed emitter 25 controls the flow and circulation of the water inside it. While the photosynthetic plants are breathing on their own, the blower 23 will blow the outside air into the glass cover 2 and filter the air through the air blowing filter plate 24 to make the air in the glass cover 2 more sufficient. During the day, the sealing cover plate 7 and the support cover plate 6 are in a closed state. When it is night, detect the wind force at night through the detection device and judge through the controller. When the wind force is large, start the multiple second motors 14, and the multiple second motors 14 drive the multiple rotating shafts 13 to rotate respectively. As the multiple rotating shafts 13 rotate, the corresponding sealing cover plates 7 rotate and tilt, and the air passes through the multiple air filter plates 15 and enters the glass cover 2 to prevent the wind from blowing the dust or other sundries on the land into the glass cover 2. When the wind force is small, start the first motor 12, and the first motor 12 drives the threaded rod 10 to rotate. As the threaded rod 10 rotates, the two sliders 11 will slide in the two slide rails 9 respectively, and the support cover plate 6 will drive the multiple sealing cover plates 7 to slide, making the opening of the glass cover 2 completely exposed. And while the support cover plate 6 slides, the traction shaft 20 will drive the starting end of the filter mesh cloth to move away from the sealing plate 8, and while stretching the filter mesh cloth, the support shaft 16 and the filter mesh cloth sleeve 17 will rotate. While the support shaft 16 and the filter mesh cloth sleeve 17 are rotating, the two coil springs 22 will be subjected to torsion, and the two elastic rods 18 will push against the pressing shaft 19, making the pressing shaft 19 press the filter mesh cloth, so that the filter mesh cloth fits more closely to the top of the glass cover 2. Subsequently, when the support cover plate 6 is reset, the two coil springs 22 will drive the support shaft 16 to rotate and wind up the filter mesh cloth.
[0068] In the above, an anemometer (such as a thermal anemometer, a vane anemometer, and an ultrasonic anemometer, which is selected according to the usage scenario) is used as the detection device. After the anemometer detects the wind speed, the anemometer transmits the signal of the detected wind force to the controller, and the controller controls the corresponding switch, thereby opening the sealing cover plate 7 and the support cover plate 6 in the corresponding environment.
