The invention belongs to the technical field of environmental protection and in particular relates to a method for utilizing the fermentation effect of microbe in remained sludge to increase the propionic acid content in organic acid which is produced under the normal temperature through replenishing carbohydrate and controlling the pH value when in reaction, the method takes the remained sludge of sewage treatment plants and mixture of urban putrescible organic waste which is produced in everyday life as raw materials.

本发明属于环境保护技术领域，具体涉及一种通过补充碳水化合物和控制反应时的pH值，以污水处理厂的剩余污泥和日常生活中产生的城市易腐有机废物的混合物为原料，在常温条件下利用剩余污泥中微生物的发酵作用提高所生产有机酸中丙酸含量的方法。

The method of the invention not only realizes the quantitative reduction, the stabilization and the resource utilization of the remained sludge and the urban putrescible organic waste, reduces the pollution of the remained sludge and the urban putrescible organic waste to environment, but also produces the organic acid which is beneficial for saprobe and the microbe which removes phosphor and nitrogen.

本发明不仅实现了剩余污泥和城市易腐有机废物的减量化、稳定化和资源化，减少了二者对环境的污染，同时产生了对污水生物除磷脱氮微生物有利的有机酸。

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。
