Zusammenfassung: | To prevent external water such as rainwater and dew condensation water from entering the inside of a gas supply body from its upper side, in a wastewater treatment device for cleaning wastewater using the action of microbes.SOLUTION: A gas supply body (10) comprises a sheet laminate (21) that is used in a state of at least partially being immersed in a liquid, the sheet laminate surrounding an inner space into which gas is supplied, a plurality of gas delivery layers (12) dividing the inner space surrounded by the sheet laminate, and a gas delivery part (14) delivering gas to the inner space surrounded by the sheet laminate, with the outer edge of the sheet laminate (21) being sealed excluding the air delivery part, and a plurality of gas discharge ports (15) being provided in the sheet laminate (21).SELECTED DRAWING: Figure 4B
【課題】微生物の働きを利用して廃水を浄化する廃水処理装置において、気体供給体の上部から内部への雨水や結露水などの外部水の侵入を防止する。【解決手段】気体供給体(10)は、少なくとも一部が液体中に浸漬された状態で利用されるシート積層体であって、前記シート積層体が取り囲む内部の空間に気体が供給されるシート積層体(21)と、前記シート積層体の内部の空間を分割する気体送出層(12)と、前記シート積層体の内部の空間に気体を供給する送気部(14)と、を含み、前記シート積層体(21)の外縁は前記送気部を除いて密閉されており、前記シート積層体(21)に排気口(15)を有する。【選択図】図4B |
