  • Patent number: 11753793
    Abstract: A treatment method for a river system in a reservoir area, comprising: S1. determining whether a time from a current date to the rainy season is less than a preset duration; S2. moving a pressure sensor upward; S3. determining whether the pressure data meets corresponding conditions; S4. determining whether a duration of the pressure data is less than the preset duration; S5. determining whether an interval between the current time and the time for collecting pressure/nitrogen and phosphorus is greater than a preset number of days; S6. acquiring an image information of a river bottom, and sending it to neural network model for identification to obtain a depth of a sludge; S7. determining whether the depth of a sludge has reached a dredging depth, if so, starting a sludge pump to clean up; S8. collecting nitrogen and phosphorus concentration, and removing nitrogen and phosphorus when the concentration exceeds a standard.
