網頁2014年3月21日 · from our in class work 網頁fEffect of Organic Wastes on. Stream Ecosystems. Streeter-Phelps Model DO sag curve. Many equations and computer programs are available. today to describe the quality of … 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. J., 1960, Oxygen Balance of an Estuary, Journal of the Sanitary Engineering Division, ASCE, Vol. 86, No. SA3, Proc. Paper 2472, May, 1960 • Schnoor J. … 查看更多內容 The Streeter–Phelps equation determines the relation between the dissolved oxygen concentration and the biological oxygen demand over time and is a solution to the linear first order … 查看更多內容 The simple Streeter–Phelps model is based on the assumptions that a single BOD input is distributed evenly at the cross section of a stream or river and that it moves as plug flow with no mixing in the river. Furthermore, only one DO sink (carbonaceous … 查看更多內容 • Water pollution • Water quality modelling • Biochemical oxygen demand • Oxygenation (environmental) • Oxygen saturation 查看更多內容 initial project plan template
