A water body surface garbage treatment system, in which the drive shaft in the inner mixing channel drives the outer frame, inner bracket, standpipe, and stirring outer hook to rotate, so as to crush and disperse the water body and various garbage contained in the water body, and the inside of the outer frame The auxiliary heating device provided can provide an additional heat source, the pipe drug outlet hole and the hook drug outlet hole can replenish pollution control drugs online, the high-temperature gas delivery pipe can provide heat energy to the mixing channel, and the upper and lower filter screens and extraction net trays can improve the filtration efficiency. With the screening efficiency, the temperature measuring sensor arranged in the mixing channel can monitor the temperature in the mixing channel. This design not only has the function of timely treatment, will not cause repeated pollution, can carry out hydropower generation and waste utilization, but also has a strong stirring function, good crushing and dispersing effects, and can supplement pollution control drugs online, and the pollution control effect is good.
