The invention relates to collecting and processing equipment, in particular to water surface waste collecting and processing equipment suitable for water conservancy projects. The equipment comprisesa whole machine support, a collecting support, a dewatering outer support, a dewatering inner support, a power mechanism, a pushing mechanism, a planetary gear mechanism and a dehydrating mechanism; the collecting support is fixedly connected to the right end of the whole machine support, the dewatering outer support is fixed and in communication with the right end of the whole machine support, and the upper end of the collecting support is fixedly connected to the dewatering outer support; and the dewatering inner support is fixedly connected to the interior of the dewatering outer support, and the power mechanism is rotationally connected to the whole machine support. The water surface waste collecting and processing equipment can be applied to water surface waste collection of the waterconservancy project, the power mechanism is driven to move by utilizing the kinetic energy of the water flow, and the power mechanism provides power for the equipment; and the collecting support cancollect the waste on the water surface, the collected waste is pushed into the dewatering inner support through the pushing mechanism to be subjected to dehydration treatment, and the dehydrating mechanism is used for dehydrating the waste and separating the water from the waste.
