PURPOSE: An aerator is provided to externally drain water body and condensed water back-flowing into an air feeding pipe and an air diffusing pipe, and prevent the narrowness of the air feeding pipe and the blockage of the air diffusing pipe by washing solid matters, thereby omitting an inconvenient work for disassembling the air diffusing pipe in order to artificially ventilate an air outlet, and maintaining the high oxygen transfer rate of the air diffusing pipe. CONSTITUTION: An aerator includes a blower(10), an air diffusing pipe(30), an air feeding pipe(20), a water storage part(70), a discharging pipe(40), and a pump. The blower generates compressed air. The air diffusing pipe diffuses micro-bubbles into water through an air outlet. The air feeding pipe feeds the compressed air to the air diffusing pipe. The water storage part stores water bodies such as reaction liquid and condensed water back-flowing into the air feeding pipe. The top of the discharging pipe communicates outside, and the bottom of the discharging pipe communicates with the water storing part. The pump pumps the water bodies. The inlet of the pump communicates with the water storing part through the discharging pipe. The pump drains the water bodies which back-flow and are collected in the water storage part in case of non-aeration. [Reference numerals] (AA) Air; (BB) Washing water; |
