To provide a siphon drainage system capable of suppressing generation of abnormal noise inside a storage tank, while maintaining the drainage capacity brought about by siphon force.SOLUTION: A siphon drainage system includes: a storage tank 20 for storing drainage flowing in from an inflow port 18A; a horizontal pipe 26A connected to the storage tank 20 for discharging the drainage from the storage tank 20 horizontally; a vertical pipe disposed on a downstream side of the horizontal pipe 26A for generating siphon force by letting the drainage from the horizontal pipe 26A flow down; and an air-supply pipe 30 having an air-supply upstream portion 32 disposed inside the storage tank 20, extending therein such that an opening 36A on an end side is connected to the horizontal pipe 26A and an opening 32A on the other end side is at the lowest portion in a vertical direction, with an intake hole 32B formed on a pipe side surface on a lower side in the vertical direction than a top end E1 of the inflow port 18A, the air-supply pipe letting the air inside the storage tank 20 flow into the horizontal pipe 26A.SELECTED DRAWING: Figure 2
【課題】サイホン力による排水能力を維持しつつ、貯留槽内での異音の発生を抑制する、サイホン排水システムを提供する。【解決手段】サイホン排水システムは、流入口１８Ａから流入した排水を貯留する貯留槽２０と、貯留槽２０に接続され、貯留槽２０からの排水を横方向に排出する横引き管２６Ａと、横引き管２６Ａよりも下流側に配置され、横引き管２６Ａからの排水を流下させることによりサイホン力を発生させる竪管と、一端側の開口３６Ａが横引き管２６Ａに連結され、他端側の開口３２Ａが鉛直方向の最下部となるように延在する給気上流部３２が貯留槽２０内に配置され、流入口１８Ａの上端Ｅ１よりも鉛直方向下側の管側面に吸気孔３２Ｂが形成され、貯留槽２０内の空気を横引き管２６Ａの内部へ流入可能な給気管３０と、を備えている。【選択図】図２
