中文摘要 |
根据微生物反应动力学模型,推导了分离式膜生物反应器水力停留时间公式,并以此公式为基础,分析与探讨了膜生物反应器的影响因素。分析结果表明,对膜生物反应器影响程度由大到小的因素为底物最大比降解速度常数K,饱和常数KS,维持常数m,真产率系数YG,最大比增殖速率μm.最后简化了水力停留时间公式,其简化形式为:T=1.1×(1/β-1)(KS+L)/KS0. |
英文摘要 |
Based on the microorganism kinetic model the formula for computing the hydraulic retention time in the membrane bioreactor system(MBR)is derived,and then influencing factors of MBR are discussed.The results showed that the influencing factors are listed in order from strength to weakness as maximum specific removal rate K,saturation constant KS,maintenance coefficient m,net bacteria yield coefficient YG and maximum specific growth rate μ m.Finally,the formula is simplified and its simple form is as follows: T =1.1×(1/β -1)(KS+L)/KS0. |
