摘　　要：橡胶促进剂CBS废水盐分高、COD浓度高,废水中含多种杂环有机物,难降解、难生化,属于高浓度难降解有机废水.废水经蒸馏预处理后采用生物接触氧化法处理,试验考查了生物降解效果,并对橡胶促进剂CBS废水生物接触氧化处理过程进行了动力学分析,以Monod关系式为基础,建立了生物接触氧化法的动力学方程.依据实验结果归纳出生物接触氧化法处理CBS废水动力学方程:(t)/(S0-Se)=2.629(1)/(Se)+2.158,同时求得橡胶促进剂CBS废水20～25℃时的动力学参数Umax=0.463 g/L·h,KS=1.218 g/L,为废水生物处理系统的设计和运行提供了依据.Accelerator CBS wastewater contains heterocyclic organics and high concentrations of salinity and COD, and is difficult to be degraded and bio-treated. The experiment on wastewater treatment by bio-contact oxidation process is conducted after pretreatment by distillation. The kinetic process of bio-contact oxidation treatment on accel erator CBS wastewater is discussed. Based on Monod equation, a kinetic equation t/S0-Se=2.629 1/Se＋2.158 is proposed aiming at bio-contact oxidation process. According to the experimental data on CBS wastewater treatment by bio-contact oxidation process, the kinetic parametersUmax=0.463g/L·h,Ks=1.218g/L within 20-25℃ are determined , which might provide a reliable basis for engineering design and operation parameters.
