摘　　要：文中通过理论推导说明了BOD5测定时应注意的问题,同时指出,为比较不同废水中可生化降解有机物的多少,测得的BOD5与UBOD(完全生化需氧量)的比值应为0.68左右,在此基础上才能可靠地计算BOD5/COD的值,进而判断废水的可生化性。最后,文中以某工业废水BOD5测定为例,对BOD5测定时需注意的问题进行了验证说明。Issues that arouse attention in the measurement of BOD5 were illustrated. To compare the amount of biochemical organic matter among various kinds of wastewater, the ratio of BOD5 to UBOD was about 0.68, based on which the value of BOD5/COD was reliable, and biochemical ability of wastewater can be concluded. BOD5 measurement was verified by taking BOD5 in industrial wastewater measurement as an example.
