摘要
完成了若干废水的好氧和厌氧生化培养实验,结果证实了以下假定和推论:在好氧条件下,TOC和BOD均近似服从一阶动力学原理,并以遵守K_(TOC)=K_(BOD)的等效降解特征而相互等价。由等效耗氧原理推论了TOC与BOD的下述互换关系:BOD_5=α′·(TOC_0—TOC_5),实验测得不同废水的表现耗氧系数α′,值为1.45±0.15。在厌氧条件下,上述等价性和互换性均不成立。
A kinetic study of biochemical behaviour of BOD and TOC was performed with various wastewater and the characteristics of equivalence (KTOC =XBOD ) of them under the aerobic conditions were authenticated. It was explicated that the equivalence about degradation and oxygen consumption is related by Biodegrading Organic Carbon, and therefore the BOD can be exchanged from TOC as follws: BOD5= a×(TOC0-TOC5), Where a is the factor measured to be 1.45±0. 15.
