The air diffuser comprises a diffuser(40), a supernatant outflow means(50), and an air supply means(60). The air diffuser supplies air to the inside of an aeration tank(20) and outflows a supernatant. The diffuser comprises a lower diffuser(4), a central connecting pipe(45), and a supernatant outlet(46). The lower diffuser is fixed on the bottom of the aeration tank and supplies the air to the inside thereof. The central connecting pipe is separately connected on the upper part of the lower diffuser. The supernatant outlet is connected with the central connecting pipe and outflows supernatant from the upper aeration tank. The supernatant outlet is connected to the supernatant outlet of the air diffuser and outflows supernatant to a settling tank(70). An air provider is connected to the supernatant outlet to aerate wastewater by supplying air to the inside of the aeration tank through the air diffuser. |
