查询词典 bod

The oxygen consumed,or biochemical oxygen demand,is proportional to the organic matter converted ,and therefore BOD is a relative measure of the biologically degradable organic matter present in the system .

氧消耗量，或生化需氧量，是成正比的有机质转换，因此，生化需氧量是一个相对的措施，生物可降解的有机物，目前在该系统。

Biochemical oxygen demand is one of the most important parameters characterizing the organic pollution of wastewater and widely used in the fields of water quality monitoring and the evaluation of the wastewater treatment efficiency.

生化需氧量（biochemical oxygen demand，BOD）作为表征水体中种类繁多的有机污染物的集合参数，在水质评价、污染监测以及废水处理厂的运行分析等方面发挥着重要作用。

Biochemical oxygen demand, BOD is necessary for water quality evaluation.

根据生化需氧量公式y=L1=La(1-e-k12y)，且1/3-y是线性关系，由直线的斜率和截距便可以求出耗氧系数k1和水中总的生化需氧量 La。
