活性污泥胞外聚合物提取条件的优化
Optimization of Extraction Condition of Extracellular Polymeric Substances from Activated Sludge
摘要
Abstract
[Objective] To explore the optimal extraction conditions of extracellular polymeric substances ( EPS) from activated sludge. [ Method] The efficiency of five methods ( H2SO4, formaldehyde - NaOH, mixing, heating and NaOH) on the extraction of EPS was investigated comparatively. The optimal extraction conditions of the most suitable method were determined. [ Result ] NaOH method is the most effective in extracting EPS as DNA was less and the extraction time was shorter. The optimal extraction condition was pH of 11, extraction time of 10 minutes and agitation speed of 80 - 120 r/min. [ Conclusion] The determined optimal extraction condition provided theoretical basis for EPS study.关键词
