網頁12.4 Mathematical analysis of Oxygen Sag Curve: Streeter – Phelps equation The analysis of oxygen sag curve can be easily done by superimposing the rates of deoxygenation and reoxygenation as ... Streeter–Phelps DO sag curve and BOD development. where D {\displaystyle D} is the saturation deficit, which can be derived from the dissolved oxygen concentration at saturation minus the actual dissolved oxygen concentration ( D = D O s a t − D O {\displaystyle D=DO_{sat}-DO} ). 查看更多內容 The Streeter–Phelps equation is used in the study of water pollution as a water quality modelling tool. The model describes how dissolved oxygen (DO) decreases in a river or stream along a certain distance by degradation of 查看更多內容 In 1925, a study on the phenomena of oxidation and reaeration in the Ohio River in the US was published by the sanitary engineer, … 查看更多內容 In addition to the oxidation of organic matter and the reaeration process, there are many other processes in a stream which affect the DO. In order to make a more accurate model it is possible to include these factors using an expanded model. 查看更多內容 • O'Connor D.
