| 摘 要： | 采用加热法、NaOH法、硫酸法、阳离子交换树脂（CER）法、甲醛-NaOH法对3个污水厂的5种生物膜和活性污泥的胞外聚合物（EPS）进行提取实验研究,并以常规高速离心作为对照组.结果表明,不同的提取方法对同一种污泥的EPS各组分构成影响较大.一般情况下,提取总量按从多到少排列如下：NaOH法〉加热法〉甲醛-NaOH法〉...

| Abstract: | Five commonly used extraction,including heating,NaOH,H2SO4,cation exchange resin(CER),formaldehyde plus NaOH were selected to study their effectiveness in extracting extracellular polymeric substances(EPS) from five biofilm and activated sludge samples,using regular centrifugation as a control method.The results showed that the EPS content and the proportion of the components were strongly dependent on the extraction methods.The efficiency of the extraction methods,in decreasing order,for all sludge samples... |
