1. A 500-meter-long aquatic plant floating bed is set at the periphery of the water area to be treated, and a plurality of floating aquatic fences are set, each fence is 500 meters long.
2. Surfactant is added to the enclosure, and the blue-green algae particles are aggregated into clusters through the function of diffusion electric double layer (one of the core technologies).
Third, the multifunctional water purification boat starts the powerful ultra-micro bubble generator to work on the water surface or make a 360-degree rotation motion in situ, and inflates up and down to make cyanobacteria and algae mud masses deposited at the bottom of the lake float on the water surface, which is convenient for collection (the second core technology).
Fourthly, motorboats use the fence rope on the water surface to drive the gathered cyanobacteria to the downwind direction and concentrate them.
5. The multifunctional water purification boat opens the bow door, puts down the dumping grid and centrifugal suction system, and collects and salvages cyanobacteria at a working speed of 5 km/h..
6. The tipping grate filled with cyanobacteria automatically leads the cyanobacteria water into the mechanical dehydrator through the hydraulic device. Efficient mechanical dewatering system, which can quickly separate algae mud and water (the third core technology)
7. Unload the dehydrated cyanobacteria with an automatic scraper and bag them with a conveying pipe.
Eight, the transport ship will continuously put the bagged dehydrated cyanobacteria ashore for disposal.
Features and innovations of this scheme:
1. The multifunctional environmental protection work boat integrates oxygen aeration and emergency power supply.
2. Efficient double-layer electrical symbols make cyanobacteria suspended in water quickly gather into a group.
3. The ultra-micro bubble generator on the ship produces ultra-micro bubbles, which make the cyanobacteria surface to form centralized collection.
4. In the whole process of collecting, salvaging and dehydrating cyanobacteria, the multifunctional environmental protection work boat needs to run for three times, the first time to generate negative ions in the water body, the second time to generate positive ions in the water body, and the third time to aggregate cyanobacteria. Every operation has a certain time interval, and the multi-functional environmental protection work boat can cross-operate in several paddocks, which greatly improves the work efficiency.
5. By using the above method, that is, the double-layer electric symbol and the action of ultra-micro bubbles, the dead cyanobacteria mud deposited at the bottom of the lake surfaced and was removed from the aquatic ecosystem through collection, which completely solved the serious problem that the fishy smell in the water body of the waterworks could not be removed, greatly reduced the water production cost of the waterworks in summer and greatly improved the inherent quality of tap water.
6. Solid-liquid separation technology and equipment enable algae water entering the device to be quickly separated and dehydrated to form algae slurry and bagged, which is combined with the pipeline for continuous operation, greatly improving the efficiency.
