摘　　要：在高盐条件下,通过耐盐菌对硝基苯废水降解动力学实验,模拟得出在盐度分别为1%和3%时硝基苯浓度对生物降解影响的动力学模型。在1%和3%盐度条件下,菌株N18对硝基苯的降解动力学符合典型的底物抑制模型。1%盐度时,菌株N18的模型参数为:μmax=1.61132,Ks=48.5376,Ki=93.39571,R2=0.98138;3%盐度时,菌株N18的动力学参数为:μmax=1.47182,Ks=42.67817,Ki=101.28224,R2=0.9814。Under the high-salt conditions, degradation kinetics experiments was made on nitrobenzene wastewater through the salt-tolerant bacteria, simulation derived the kinetic model of nitrobenzene concentration to biodegradable influence, in the salinity of 1% and 3% respectively. Under the 1% and 3% salinity conditions ,the degradation kinetics of stain N18 to nitrobenzene can be expressed by Andrew equation （typical substrate inhibition model）. Under the 1% salinity, the kinetic parameters of strain N18 are μmax=1.611 32, Ks=48.537 6, Ki=93.395 71, R^2=0.981 38. Under the 3% salinity, the kinetic parameters of strain N18 are μmax= 1.471 82, Ks= 42.678 17, Ki 101.282 24, R^2= 0.981 4.
