Biochemical Oxygen Demand is an important control index in wastewater effluent ,but it takes longer time(5 days)for its determination,while the time for measuring the Chemical Oxygen Demand is shorter(10 hours).

生化耗氧量是废水排放的重要控制指标，但它的测定需要时间较长，而化学耗氧量的测定时间较短，这两者是否存在稳定的关系？

Generally aerobic and anaerobic wastewater treatment plants require substantial areas of land for the effective treatment of liquid waste streams to achieve very low levels of Biochemical Oxygen Demand and Chemical Oxygen Demand reduction.

通常，好氧和厌氧的废水处理设备需要大量土地以进行有效的废液处理，把生化需氧量和化学需氧量减少到非常低的程度。

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。
