| 摘 要： | 分别用UASB与完全混合反应器对2-氯苯甲酸(2-CBA)在厌氧、好氧条件下的降解进行了小试研究.结果表明,在好氧条件下,经过驯化的污泥对2-氯苯甲酸去除率达80％以上,在与葡萄糖共基质的条件下2-氯苯甲酸的降解受到抑制;而在厌氧条件下,2-氯苯甲酸很难降解,且投加不同浓度的葡萄糖对2-氯苯甲酸的生物可降解性没有明显改善,其去除率均在20％以下.

| Abstract: | The biodegradability of 2-chlorobenzoic acid under aerobic and anaerobic conditions was studied respectively using UASB reactor and completely mixed reactor. The results showed that under aerobic condition 2-chlorobenzoic acid could be removed over 80% by the acclimated sludge, and its degradation was inhibited by the presence of glucose, While under anaerobic condition 2-chlorobenzoic acid was very difficult to degrade, and its biodegradability was not markedly improved by the presence of glucose. |
