【摘要】 对BOD5的测压法测定做了较全面的探讨。指出该法经不同倍数稀释的测定值之间的差异,验证了该测定法可以表征毒性物质对微生物活性的抑制程度。通过模拟含毒性染料的印染废水活性污泥的处理,指出其不同稀释比的BOD5值可作为该处理法的设计和运行管理的重要参数。更多还原

【Abstract】 The BOD₅’S pressure determination is evaluated in our study.Comparing the differences of BOD₅ determined values by diluting the sample water which contains the poison in different proportion ,we verify that the determination principle can be used to manifest the influential degree of microbial activity affected by poisionous materials.And according to simulating the way that the active mud deals with the poisonous waste water drained away by printings and dyes industries ,the paper points out that by the different proportion of dilution ,the values of BOD₅ can be used as an important parameter of both the design of the dealing and the operation and management.更多还原
