| 摘要 |
The present invention relates to an aeration apparatus comprising: a water tank with a water storage space; a rotary shaft having a first flow path and a second flow path allowing a liquid fertilizer and an air to pass through and rotatably arranged within the water tank; a driving unit rotating the rotary shaft; a supply unit supplying the liquid fertilizer and air through the first flow path and the second flow path; and a stirring unit arranged on the rotary shaft and stirring the liquid fertilizer stored in the water tank. The aeration apparatus, according to the present invention, can increase the amount of dissolved oxygen in wastewater by uniformly distributing air to the inside of the water tank storing the wastewater and excrements, reduce the fermentation time, and enhance efficiency by consistently stirring the liquid fertilizer located in the water tank, sediment precipitated on the bottom of the water tank, with air. |
