摘　　要：基于COD_B与废水底物浓度成正比的假设,推导了COD_(Cr)在生化降解过程中的变化规律。研究了变化规律之特点,并以实验证实了规律的正确性。论证了以COD_B/COD_(Cr)为指标的废水可生化性评价方法的可行性。An equation of biodegradation of CODB is given, which is based on the hypothesis of CODcr and CA are in proportion. The character of the equation is studied. and the rightness is testified by experiment. Also, the possibility of using CODB/COD as the evaluating index of waste water biodegradation is expounded.
