| 摘 要： | 本文研究了厌氧、缺氧实验夺件下难降解苯、甲苯、乙苯、二甲苯的同分异构体（BTEX）的生物降解性能。得出了不同底物的厌氧降解变化情况和缺氧降解条件下不同底物适宜的C／N比。通过对实验结果的分析，初步确定了不同底物具有各不相同的C／N比的原因，同时得出了缺氧反硝化与厌氧生物降解过程有可能同时发生的结论。

| Abstract: | Biodegradation of benzene, toluene, ethylbenzene, and xylenes which are resistant to biodegradation in wastewater by anaerobic and anoxic batch reactors were studied. Moreover, the characteristic of anaerobic biodegradation and fitting C/N ratios for different substrates in the process of anoxic biodegradation were observed. By analyzing experimental results, reasons for different C/N ratios to different sttbstrates were found. We also concluded that anaerobic biodegradation and anoxic biodegradation may take place simultaneously. |
