The following results were achieved:(1) The 2-CNB.4-CNB and 3,4-DCN-degrading anaerobic granular sludge was acclimated and enriched when a mixture of these three chloronitrobenzenes was employed as influent of anaerobic bioreactor.

• 2-CNB、4-CNB和3,4-DCN三种氯代硝基苯类同系物共存条件下，以易降解有机物作为共基质进行厌氧处理，在厌氧反应器中可培养获得转化降解2-CNB、4-CNB和3,4-DCN的厌氧颗粒污泥。
