| 摘 要： | 采用SBR反应器,研究分别以葡萄糖和乙酸钠为共基质时3-硝基酚的好氧降解.试验结果表明:在SBR反应器中,以葡萄糖为共基质的3-硝基酚好氧降解效果比以乙酸钠为共基质的要好;保持反应器内初始COD浓度1 000 mg/L左右,在葡萄糖共基质条件下,初始浓度120 mg/L以内的3-硝基酚可完全降解;在乙酸钠共基质条件下,初始浓度40 mg/L 以内的3-硝基酚可完全降解;相同的初始3-硝基酚浓度、相同的硝基酚去除率下,葡萄糖共基质条件下3-硝基酚的平均降解速率大于乙酸钠共基质条件下的平均降解速率.

| Abstract: | Oxygen degradation of 3-nitrophenol(3-NP) was investigated in sequencing batch reactors(SBR) using two different co-substrates,glucose and sodium acetate.The results showed that glucose was found to be a better co-substrate for 3-NP oxygen degradation when compared with sodium acetate.The COD initial concentration of the reactors was kept as 1 000 mg/L.Maximum 3-NP initial concentration was 120 mg/L with glucose as co-substrate,while maximum 3-NP initial concentration was 40mg/L with sodium acetate as co-substrate.With the same 3-NP initial concentration and 3NP removal efficiencies,the average 3-NP degradation rate with glucose as co-substrate was greater than that with sodium acetate as co-substrate. |
