摘要

The performance of aerobic- and anaerobic-SBR in treating Orange Ⅱ-containing wastewater was investigated. The result from a specific oxygen uptake rate (SOUR) study showed that the Orange Ⅱ compound did not exert significant inhibitory effects on the activity of activated sludge microorganisms. It was found that Orange Ⅱ and organic loading rates affected the treatment performance in terms of COD and Orange Ⅱ removal efficiencies in the SBR systems. The increase of organic loading rate from 2.66 to 5.32 g COD/l day had slightly improved the COD removal efficiency in aerobic-SBR but deteriorated the COD removal efficiency in anaerobic-SBR. On the other hand, the increase of organic loading rate improved the Orange Ⅱ removal efficiency in both SBR systems. In the case of 100 mg/l Orange Ⅱ addition, the average fraction of Orange Ⅱ removed was 15 and 80% in aerobic- and anaerobic-SBR, respectively. The anaerobic microbes exhibited five times higher Orange Ⅱ removal rate compared to aerobic microbes.
