Method and system for controlling and treating black and odorous river water pollution

The invention relates to the technical field of river treatment, in particular to a black and odorous river water pollution control and treatment method and system.During work, a sewage monitoring module is taken down and installed at a concave river convergence port to collect pollution information; then a pollution flow calculation module of the evaluation module calculates the pollution amount of the current confluence section based on the pollution information, then the ship body is started to the position with the large pollution amount, the water body is purified through a purifier and a garbage collector, and garbage in the water body is cleared away through the garbage collector; the treatment cost calculation unit calculates the pollution treatment cost in combination with the working time of the ship body and the consumed water purification material, and then an alarm unit gives an alarm after the treatment cost exceeds a preset value so as to supervise and urge a user of the corresponding confluenc
