Effects of organic loading rate and salinity on characteristics ofextracellular polymeric substances (EPS) of aerobic granules
负荷及盐度对好氧颗粒污泥EPS的影响

Effects of organic loading rate (OLR) and salinity on the properties of extracellular polymeric substances (EPS) in aerobic granules, and the relationship between EPS and specific oxygen uptake rate (SOUR) and porosity were investigated in this work. It was found that OLR affected characteristics of EPS more significantly than the salinity did. The carbohydrate EPS negatively correlated with SOUR, and the protein EPS also negatively correlated with porosity. Additionally, with respect to the saline shock, granules under a high OLR were more stable than those under a low OLR.
