The invention belongs to the technical field of water treatment, and discloses a scum purging system for an air floatation tank and a manufacturing method, the scum purging system comprises a flushing water pump, a purging main pipe, a purging branch pipe, a nozzle pipe, a nozzle and a flushing water pump switch controller; a flushing water pump, a purging main pipe, a purging branch pipe, a nozzle pipe and a nozzle are sequentially arranged from the water inlet end to the water outlet end; backwash water is distributed to a plurality of purging branch pipes and nozzle pipes which are mounted on a main pipe, and is sprayed into the bottom of a scum tank at a certain angle through nozzles, so as to purge scum entering the scum tank. The surface of the system adopts corrosion-resistant ceramic tiles, so that the friction force is small, and the scum self-flowing property is A backwashing water source is effluent of the air floatation tank, so that backwashing holes are prevented from being blocked; and back-flu
