| 摘 要： | 活性污泥的絮凝性能直接影响出水SS浓度,而胞外多聚物(EPS)是影响活性污泥絮凝性能的重要因素。从EPS的组分及其化学性质入手,结合现有的活性污泥絮凝机制评价了EPS在活性污泥絮凝性能中的重要作用,系统分析了EPS组分对污泥絮凝性能的影响,以及EPS产量和组分的影响因素,并就近年来的研究热点———松散层EPS、致密层EPS与活性污泥絮凝性能的关系进行了归纳,还对利用EPS提高活性污泥絮凝性能的技术应用进行了总结。最后,对该领域的研究方向进行了展望。

| Abstract: | The effluent SS is greatly affected by the flocculation properties of activated sludge,while the extracellular polymeric substances(EPS) are the key element determining the activated sludge flocculation properties.The importance of EPS to the activated sludge flocculation properties is discussed based on the composition,chemical characteristics of EPS and the current flocculation theories.The influence of EPS composition to the activated sludge properties and the elements affecting the output and composition of EPS are systematically analyzed.Furthermore,the present research focus such as the relationship of loose bed EPS(LB-EPS) and tight bed EPS(TB-EPS) to the activated sludge flocculation properties are summarized,the application of EPS on the activated sludge flocculation is also presented.At last the prospect in this topic is proposed. |
