| 摘 要： | 研究了膜生物反应器(MBR)中间歇排泥以及连续排泥条件下污泥停留时间(SRT)与污泥胞外聚合物(EPS)变化的关系。试验结果表明:在间歇排泥方式下的污泥EPS都明显高于连续排泥方式下的。随着SRT的增加,附着型EPS浓度先是稍有减少,之后快速增加,溶解性EPS则增加。

| Abstract: | The relationships of the diversification of extracellular polymeric substances(EPS) with sludge retention time(SRT) under continuous sludge discharge pattern and incontinuous sludge discharge pattern in membrane bioreactor(MBR) were studied.Experimental results showed that compared to continuous sludge discharge pattern,concentrations of EPS were higher under incontinuous sludge discharge pattern.As sludge retention time increased,the concentration of bound EPS decreased slightly and then increased rapidly,... |
