摘　　要：挥发性有机酸 (如乙酸 )是污水处理厂污泥消化工艺中的主要产物。传统的方法只能测定样品中脂肪酸的总含量 ,而不能测出单种酸的含量。本方法将离子色谱技术应用于污泥挥发性脂肪酸中甲酸和乙酸的分别单独测定。实际样品测定结果证明 ,离子色谱技术完全可以用于消化污泥中挥发性脂肪酸的检测 ,并具有快速。Volatile organic acids are the main products in sludge digestion process in sewage treatment plants. The traditional methods can only determine the total concentration of volatile fatty acids in sludge, but the individual components can not be analyzed. This paper presents a method of ion chromatography that can analyze the main components of volatile fatty acids (formic acid and acetic acid) in sludge. Experimental results demonstrate that the method is applicable for the detection of volatile fatty acids in digested sludge and has the advantages of rapidity and accuracy.
