摘要
本文通过平行的生化培养试验证实,在“参与耗氧的含碳有机物”这一意义下,TOC和BOD是等价的,两者均服从一阶动力学过程并具有相同的降解速率常数,两者之间通过TOC的耗氧系数α和不可生化量b而存在线性的一般关系:BOD_5=α·(TOC—b)·exp(-5k_1).以在研究中关于BOD_5,与TOC的比值关系只是这一线性关系的特例.
TOC and BOD are the water-quality parameters for determining organism mass in water. There exists a certain relation between them. Reported in this paper is that by the parallel experiments of biochemical culture, TOC and BOD are equal valence under the meaning of 'carbon-containing organisms taking part in oxygen con-sumption', and both obey one valence kinetic reaction andhave the same constant of degradation rate. There is a general linear relation between TOC and BOD by the coefficient a of oxygen consumption for TOC and inde-gradable mass b for BOD: BOD = a(TOC-b)-exp(-5k1)
