The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.

2分批试验结果证明，颗粒污泥降解2-CNB和4-CNB遵循一级动力学，在厌氧条件下，CNB发生序列的硝基还原与脱氯作用，苯环上的硝基比氯原子更容易受到亲电子攻击，发生还原反应生成氨基；所获得的颗粒污泥具有对位脱氯活性，可使4-CA进一步脱氯形成苯胺。2-CNB和4-CNB厌氧降解的建议性途径为： ZVI(Zero-valentiron)对2-CNB和4-CNB的作用主要是将苯环上的硝基还原为氨基；在ZVI与污泥共还原转化体系中，ZVI对氯代硝基苯的硝基转化具有一定的促进作用，但因ZVI对中间产物的吸附特性，终产物形成速率趋慢。
