Biochemical oxygen demand 中文
生化需氧量（Biochemical oxygen demand，簡寫為BOD），是水體中的好氧微生物在一定溫度下將水中有機物分解成無機質，這一特定時間內的氧化過程中所需要的溶解氧量 。 WebBiochemical Oxygen Demand Background We perform the BOD analysis to determine the amount of oxygen required to biochemically break down the organic material in wastewater and the oxygen used to oxidize inorganic materials such as sulfides and ferrous iron. Unless an inhibitor is used, the BOD test may also measure the amount of oxygen
