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.
