description The utility model relates to an unpowered nitrification liquid oxygen escape device which adopts a baffling water inlet structure, dissolved oxygen is fully released in the process that nitrification liquid slowly rises in a first-stage oxygen escape area, and dissolved oxygen in anoxic gas is further reduced; the arrangement of the middle pipe ensures that a water flow gradient is not formed in the process that nitrification liquid flows from the first-stage oxygen escape area to the second-stage oxygen escape area, and air is prevented from entering nitrification reflux liquid; nitrification liquid enters the third-stage oxygen escape area through a flow guide opening in the bottom of the second-stage oxygen escape area, the contact area between the nitrification liquid and inlet water is large, in the section, denitrifying bacteria form dominant bacteria, and organic carbon in the inlet water is fully utilized for denitrification. The device is high in oxygen escape speed, simple in structure, convenient t
