聚合氯化铝投加时间对好氧颗粒污泥的形成和胞外聚合物的影响
Influence of poly aluminium chloride dosing time on formation and EPS of aerobic granular sludge
摘要
Abstract
This paper analyzed the formation process of granules,and researched the content changes and the spatial distribution of extracellular polymeric substances by adding poly aluminium chloride in 1—7 days and 8—14 days respectively during the process of cultivating aerobic granular sludge. The granules formation time of the reactor adding PAC in 8—14 days was 6 days ahead of time,and the sludge granules had regular shape,uniform size,and good contaminants removal performance. Moreover,the reactor extracellular polymeric substances and proteins content was higher,and increased with the formation of granules and then decreased slightly,and stayed stable after the granules matured. The value of proteins/polysaccharides during the process of granules formation increased by more than 2.5 times,which was conducive to the formation of granular sludge. Multiple fluorescent staining showed that different PAC dosing times between the reactors led to different distributions ofβ-polysaccharides and lipids and live cells,but had smaller effect on the distribution of proteins andα-polysaccharides .关键词
