摘　　要：利用构建的优势降解菌群强化好氧颗粒污泥,提高制浆造纸废水的降解效果,在厌氧处理的基础上,原始好氧污泥处理后,废水COD由629 mg/L降至203mg/L,废水色度由118 C.U.降至91 C.U.;而强化好氧污泥处理后,废水COD由629mg/L降至146mg/L,废水色度由118 C.U降至72 C.U.。并研究了好氧处理阶段的微生物过程反应动力学以及制浆废水COD降解动力学,建立了该处理阶段废水COD降解的动力学模型。The aerobic granular sludge was intensified with the mixed-culture community constructed.The pulping effluent was treated firstly with anaerobic sludge,and followed by further treatment of aerobic granular sludge and intensified aerobic granular sludge,respectively.COD of pulping effluent was decreased from 629mg/L to 203mg/L and chroma declined to 91C.U.from 118C.U.after treatment by original aerobic granular sludge.By contrast,the efforts of intensified aerobic sludge was better,COD was dropped to 146mg/L from 629mg/L,and chroma declined to 72C.U.from 118C.U.For the original aerobic granular sludge and intensified aerobic granular sludge,the paper studied their microbial process reaction thermokinetics and degradation kinetics of pulping effluents in aerobic treatment phase,and two kinetic models for degradation of pulping effluents were established.
