| 中文摘要 |
| 利用半连续投料的驯化方法对3种不同来源的生物污泥厌氧降解2,4,6-三氯酚(2,4,6-TCP)过程中补充碳源的影响进行了研究。结果表明,经过50～60d的驯化,取自有机化工厂和造纸七厂的2种污泥的比降解速率(氯酚/SS)分别达到了0.6mg/(g·d)和0.2mg/(g·d),而取自北京啤酒厂UASB反应器的污泥的比降解速率只有0.03mg/(g·d)～0.05mg/(g·d).补充碳源对北京啤酒厂UASB污泥有明显的促进作用,而对于取自有机化工厂和造纸七厂的污泥则有抑制作用;研究表明2,4,6-TCP的厌氧生物降解过程符合一级反应模型。 |
| 英文摘要 |
| A method of semicontinuous acclimatization was used to study the influence of a supplemental carbon source on anaerobic biological treatment of 2,4,6-trichlorophenol in three kinds of sludge. The results showed that after 50～60 days acclimatization, the sludge coming from Beijing Organic Chemical Industry Plant (BOCIP) and Beijing Seventh Paper Mill (BPM) have a high specific degradation rate of 0.6mg/(g·d) and 0.2mg/(g·d), respectively. The sludge coming from the UASB reactor in Beijing Brewery Corporation (BBC) has a low specific degradation rate of 0.03～0.05mg/(g·d). For sludge coming from BBC, the supplemental carbon source has a stimulatory effect compared with chlorophenol as a unique carbon source. But in culture vessels filled with sludge coming from BOCIP and BPM, very little inhibit effect can be observed. After acclimatization, the biodegradation process of 2,4,6-TCP tallies with the pattern of first order reaction. |
