摘　　要：研究了工程菌株Fhhh降解精对苯二甲酸 (PTA)石化废水的动力学 .将测得的Fhhh降解废水的 6项动力学参数值、废水自然参数值、废水排放标准控制值 ,输入环境生物技术信息学软件 (Ebis)进行计算 .结果表明 ,来源于 3种保存方法的Fhhh菌株中 ,所需反应器的最小体积 (Vmin)为 1 30 9m3 ,比降解率 (qA)的最高数值为0 0 1 36h- 1,是土著菌YZ1的 4倍 ,高于国内外同类研究的 4项数值 ,低于同类研究的 2项数值 .结果表明 ,Fhhh工程菌株具有降解PTA废水的显著优势 .Degradation kinetics of the purified terephthalic acid (PTA) petrochemical wastewater with the functional strain Fhhh was conducted in this research. Inputting the values of the 6 kinetics parameters obtained from the test, the values of the natural parameter and the values of the standard parameters for discharging wastewater into the environmental biotechnological informatics software (Ebis),the minimum reactor volume (V min) required and the specific degradation rate (q A) were calculated based on the activated sludge process. The minimum value of V min was 1309m 3 as well as the highest value of q A was 0.0136h -1 among the Fhhh preparations kept in three different methods. The highest value of Fhhh q A was 4 fold of that of the native bacterium YZ1,and higher than that of the data published by 4 researchers and lower than that of by 2 researchers. The results show that Fhhh has the obvious potential for the degradation of PTA wastewater.
