title: Pilot regulation of MnP-SA for treating PTA wastewater.
abstract: In the pilot study of treating the purified terephthalic acid (PTA) wastewater with the functional Strain Fhhh in the carrier activated sludge process (CASP), the ratio of COD: TN: TP and the concentrations of Cu, Mn, Se and Zn were controlled to improve the manganese peroxidase (MnP) levels for increasing the treatment efficiency. When the ratio of COD: TN: TP was 100: 0.36: 0.15 and the concentrations of Cu, Mn, Se and Zn were 0.54, 5.07, 0.00 and 0.08 mg/L, the MnP specific activity (MnP-SA) reached 689 U/L, and the sludge loading rate to COD(SLRC) was 1.09 d(-l), which was 4--7 fold of that in other processes reported. The data indicated that improving MnP level could enhance the degradability of Fhhh. And the potentials of Fhhh and CASP will be also discussed in this paper.
