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。A method of semicontinuous acclimatization was used to study the influence of a supplemental carbon source on anaerobic biological treatment of 2,4,6trichlorophenol in three kinds of sludge. The results showed that after 5060 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 06mg/(gd) and 0.2mg/(gd), respectively. The sludge coming from the UASB reactor in Beijing Brewery Corporation (BBC) has a low specific degradation rate of 0.030.05mg/(gd). 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 2,4,6TCP tallies with the pattern of first order reaction.
