摘　　要：通过静态模拟实验探讨了厌氧折流板反应器各级基质降解动力学。试验结果表明在25℃条件下,各级有机底物最大比降解速率Vmax和饱和常数Ks分别依次为3.06/d-1、1.52/d-1、0.97/d-1和20157.89mg/L、2947.38mg/L、7007.40mg/L。通过各级Vmax的比较可知,级中微生物活性最大,微生物处于对数增殖期,而、级中微生物处于减速增殖期或内源呼吸期。The substrate degradation kinetics of each cell of ABR was studied by static simulative experiment. The results showed that under 25℃ maximum specific degradation rate(V_ max ) and saturation constant K_s of organic substrate in three cells are 3.06 d -1 , 1.52 d -1 , 0.97 d -1 and 20157.89 mg/L,2947.38 mg/L, 7007.40 mg/L, respectively. By comparison ofV_ max , we knew that microbial activity is the most strong and microbes are in their logarithm growth period in first cell; but in the second and third cells, the microbes are in their declining growth or endogenous respiration period.
