摘要

An aeration device which is immersed in diluted/used seawater, said diluted/used seawater being the water to be treated, and generates microbubbles in the diluted/used seawater, comprising: an air feeding line (L5) for feeding air (122) from blowers (121A) to (121D), said blowers being discharge means; a fresh water tank (140) and a feed pump (P1) which are water-feeding means for feeding fresh water (141), i.e. water, to the air feeding line (L5); and an aeration nozzle (123) provided with an air diffusion membrane (11) having a slit through which the water-containing air is fed.
