Biochemical oxygen demand 中文
WebBiochemical Oxygen Demand (BOD), representing the biodegradable organic load in water, is a prime parameter to assess water quality. Estimation of biochemical oxygen demand requires prolonged incubation of water samples. Thus, it is a time-consuming as well as energy-consuming process. Therefore, it is not possible to respond rapidly for ... Web成功经验 1 一个DEMO讲一个故事 对《生化奇兵》来说，Cemo的完成是非常激动人心的时刻。它使团队在观点、问题、解决方法，外界的鼓励以及内部的支持等方面得到了统一。举例来说，自从在GameSpot上展示了一个单独房间的图形Demo之后，

WebDissolved oxygen (DO) is measured at the beginning of the analysis and after a 5 day, in-the-dark, 20 'C incubation period. The difference of the DO between the beginning and end of analysis is used to calculate the BOD. The BOD test is a bioassay.

WebSep 15, 2014 · Conducting the Test. BOD is determined by analyzing the difference in dissolved oxygen from a sample for five days. Because of this standardized time, BOD is often referred to as BOD-5. The dissolved oxygen readings are usually in parts per million (ppm). Higher BOD indicates more oxygen is required, which is less for oxygen …
