Black and odorous river branch repairing system and application thereof

The invention provides a black and odorous river branch repairing system and application thereof, and relates to the technical field of black and odorous water body treatment. The black and odorous river restoration system comprises an ecological floating island and an electrode electrolysis device arranged in sludge at the bottom of the black and odorous river, wherein the ecological floating island treats pollutants in a water body of the black and odorous river through a floating island platform. The electrode electrolysis device is used for electrolyzing and removing bottom mud pollutants in the black and odorous river. Meanwhile, the ecological floating island further comprises an electric energy control system arranged on the water surface, and the electric energy control system can provide energy for the black and odorous river branch repairing system. According to the black and odorous river repairing system, through mutual cooperation of all the units, various pollutants in bottom mud can be degraded
