| 摘 要： | 对生物转盘处理油田污水技术进行了数学模拟,并建立了动力学方程式。结果表明,反应速率常数受温度(Q)、水力停留时间(M)、pH值(N)等因素的影响。在N为7,Q为20℃,M为7 h,转速为4 r/min,盘片浸没面积为45%,进水化学需氧量(COD)为600 mg/L的条件下,生物转盘降解有机物的动力学方程为Cl=C0/exp(0.95×102Q-6.93M-0.70N-1.30t),式中:C0,Ct分别为进水和t时刻出水COD。

| Abstract: | The process of treating oilfield sewage by biological rotating contactor was simulated,and its kinetic equation was established.The results showed that the reaction rate constant was affected by temperature（Q）,hydraulic retention time（M） and pH value（N）.Under the conditions of N 7,Q 20℃,M 7h,the area of submerged disc 45%,the chemical oxygen demand（COD） of influent 600mg/L,the overall reaction equation of degradation of COD was Ct=C0/exp（0.95×10^2Q^-6.93M^-0.70N^-1.30t）, where C0 and Ct were influent COD and effluent COD at time t,respectively. |
