| 摘 要： | 采用磁力搅拌-阳离子交换树脂法提取了活性污泥中的胞外聚合物（EPS）。以糖类、蛋白质、核酸含量为EPS提取效果的评价指标，确定了最佳提取条件：搅拌时间为4h，搅拌转速为1000r／min，在污泥浓度MISS为12．6g／L时树脂用量为15g。与传统高速离心法的对比研究表明，该方法具有较高的EPS提取效率，测定结果的相对标准偏差〈3％。

| Abstract: | Extracellular polymeric substances (EPS) in activated sludge were extracted by magnetic stir and H-type cation resin exchange, and the content of protein, polyose and nucleic acid were the evaluating indexes. The optimized conditions for extracting were mixing time of 4 h, mixing speed 1 000 r/min, the cation resin dosage of 15 g when MLSS is 12.6 g/L. It has better extracting efficiency when comparing with traditional high-speed centrifugal method, the relative standard deviation (RSD) is less than 3%. |
