摘　　要：在高盐条件下,通过耐盐菌群对偶氮染料K-2BP废水厌氧降解动力学实验,模拟得出偶氮染料K-2BP和盐浓度对生物降解双重影响动力学模型。其抑制常数KIS和KT值分别为(329.5±175.8)mg/L和(39.7±27.1)g/L,并通过动力学模型预测的数据和实验数据对比,耐盐菌可用动力学模型描述其在高盐条件下对染料的降解。Decolorization dynamic model of reactive brilliant red Ko2BP by salt-tolerant bacteria were developed based on experimental results at different salt （NaC1） concentrations （5 -150 g/L） and different dye concentrations （100-600 mg/L）. The observed kinetic reaction coefficient was determined and correlated as a function of salt and dye concentrations. The values of KT and KIS are（39.7 ±27.1 ）g/L and （329.5 ± 175.8） mg/L, respectively. The dynamic model was testified by actual experimental data, the measured and theoretical values, which indicates that the model can be used to describe the decolorization process of reactive brilliant red K-2BP by salt-tolerant bacteria under high salt concentration conditions completely.
