とを特徴とする汚水浄化槽。(1) In a sewage septic tank, which consists of a sedimentation separation chamber into which sewage flows, a contact aeration chamber, a sedimentation chamber, and a disinfection chamber having an outlet for treated purified water, the sewage to be treated is advected to each of the above chambers in order. A transfer flow port is provided in the partition plate that partitions the contact aeration chamber from the sedimentation separation chamber to allow the wastewater to naturally flow into the contact aeration chamber, and in addition to the transfer port, the partition plate head is connected to the contact aeration chamber. A sludge return port for returning the sludge in the contact aeration chamber to the sedimentation separation chamber is provided at a position slightly above the reference water level of the contact aeration chamber and lower than the rising water level generated on the reference water surface by air bubbles diffused in the contact aeration chamber. A sewage septic tank characterized by:
流防止を行う整流部材が延出されている実用新案登録請
求の範囲第1項記載の汚水浄化槽。(2) The sewage septic tank according to claim 1, wherein a rectifying member for preventing backflow from the contact aeration chamber to the sedimentation separation chamber extends from the lower edge of the advection port.
下で流出させる開口を有するキャップを嵌め付けた実用
新案登録請求の範囲第1項記載の汚水浄化槽。(3) The sewage septic tank according to claim 1, which is a registered utility model, in which a cap having an opening through which the sewage to be treated flows out below the reference water level in the contact aeration chamber is fitted to the advection port.
