摘要

The biodegradation and toxicity of the purified terephthalic acid (PTA) processing wastewater researched was at NJYZ pilot with the fusant strain Fhhh in the carrier activated sludge process (CASP). Sludge loading rate (SLR) for Fhhh to COD of the wastewater was 1.09d-1 and to PTA in the wastewater was 0.29d-1. The results of bioassay at the pilot and calculation with software Ebis3 showed that the 48h-LC50 to Daphnia magna for the PTA concentration in the wastewater was only 1/10 of that for the pure chemical PTA. There were 5 kinds of benzoate Pollutants and their toxicities existing in the wastewater at least. The toxicity parameter value of the pure chemical PTA cannot be used to predicate the PTA wastewater toxicity. The toxicity of the NJYZ PTA wastewater will be discussed in detail in this paper.

摘要

Ebis is the intelligent environmental biotechnological informatics software developed for judging the effectiveness of the microorganism strain in the industrial wastewater treatment system (IWTS) at the optimal status. The parameter, as the objective function for the judgment, is the minimum reactor volume (Vmin) calculated by Ebis. The rationality and the universality of Ebis were demonstrated in the domestic sewage treatment system (DSTS) with the data published in USA and China. Fhhh strain's potential for treating the purified terephthalic acid (PTA) has been proved in this research. It suggests that Ebis would be useful and universal for predicating the technique effectiveness in both DSTS and IWTS.

摘要

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 0.08mg/L, the MnP specific activity (MnP-SA) reached 689 U/L, and the sludge loading rate to COD (SLRC) was 1.09 d-1, which was 4-7fold of that in other processes reported. The data indicates that improving MnP level could enhance the degradability of Fhhh. And the potentials of Fhhh and CASP will be also discussed in this paper.
