  • 摘要: 采用一种新开发的多孔流动态悬浮填料结合自主设计的高效移动床生物膜反应器（moving bed biofilm reactor）处理城市生活废水并利用Lawrence-McCarty模型建立该系统的污染物降解动力学方程组，考察系统对有机物、氨氮、总氮的降解速率及去除效果与微生物量之间的关系。结果表明，有机物、氨氮、总氮降解动力学方程的出水浓度模拟值与实际废水处理后的出水浓度测量值拟合度良好，绝对误差分别为0.03~0.13、0.05~0.68、0.06~0.56。其中，有机物降解动力学方程的动力学常数为vmax=7.18 d-1，KS=84.67 mg·L-1（以COD计），明显高于普通活性污泥法动力学常数的一般参考值，说明MBBR系统处理生活污水中有机污染物的降解速率和去除效果优于活性污泥法。
    Abstract: A novel suspended carrier,developed by Dalian Artronics Corporation Ltd.,was employed in a high efficiency pilot moving bed biofilm reactor (MBBR) to treat municipal wastewater.Subsequently,the kinetics equations for pollutant degradation in this system were established according to the Lawrence-McCarty model,which reflects the relationship between the pollutant degradation rate or removal efficiency and the microbial biomass in the reactor.The simulated effluent values of organic matter,ammonia nitrogen,and total nitrogen were in good agreement with the measured values,with absolute errors of 0.03 to 0.13,0.05 to 0.68,and 0.06 to 0.56 being calculated,respectively.In addition,the kinetic constants calculated using the organic matter degradation equation were vmax =7.18 d-1 and KS=84.67 mg·L-1(caculated by COD),which are significantly higher than the reference values for conventional active sludge (CAS) process kinetic constants.This confirms that the pollutant degradation rate and removal efficiency of this MBBR system are superior to those of the activated sludge process.
