摘要： 采用特异性移动床生物膜反应器（SMBBR）处理模拟城市生活污水，并根据实验结果建立该工艺的污染物降解动力学方程，验证得出系统中有机污染物、总氮和总磷的最大比降解速度与饱和常数。结果表明：系统中有机污染物、总氮、总磷的最大比降解速度分别为9.79、0.513、0.226 d-1，三者的饱和常数分别为62.41、11.998、7.087 mg/L。通过降解动力学方程得到的有机污染物、总氮、总磷出水浓度模拟值和其实际出水浓度值拟合良好，误差分别为0.18~0.27、0.06~0.26和0.09~0.43。

Abstract: The specific mobile bed biofilm reactor(SMBBR) has been used for treating simulated urban domestic se-wage,the degradation kinetics equation of the pollutants of the process established,based on experimental results, and the maximum specific degradation rate and saturation constants of organic pollutants,total nitrogen and total pho-sphorus in the system have been obtained and verified. The results show that the maximum specific degradation rates of organic pollutants,total nitrogen and total phosphorus in the system are 9.79,0.513,and 0.226 d-1,respectively. The saturation constants of the three are 62.41,11.998,and 7.087 mg/L respectively. The simulated values of the eff-luent concentrations of organic pollutants,total nitrogen,and total phosphorus obtained from the degradation kinetics equation fit well with the actual effluent concentrations. The errors are 0.18-0.27,0.06-0.26,and 0.09-0.43,res-pectively.
