To explore the different effects of extracellular polymeric substance (EPS) on settleability of bulking sludge, the influent conditions changed with shortage of elements P and N for culture different bulking sludges, the EPS in different layers and their components in bulking sludges were analyzed. The results showed that no matter in the non-filamentous viscous bulking sludge or in the filamentous bulking sludge, the contents of Total-PS, of EPS in the outer layer(S-PS、S-PN), and of EPS in the middle layer(L-PS) were higher than those in the normal activated sludge. Polysaccharide content in EPS of all layers in non-filamentous viscous bulking sludge was more than that in filamentous bulking sludge, while the contents of PN of all layers in non-filamentous viscous bulking sludge were lower than those in filamentous bulking sludge. Total-EPS ((229±94) mg/g MLSS) in non-filamentous viscous bulking sludge was higher than that in normal activated sludge ((86±16) mg/g MLSS) and filamentous bulking sludge ((108±30) mg/g MLSS). The higher the contents of Total-P, Total-PN in non-filamentous viscous bulking sludge were, the bigger SVI value was and the worse sludge settleability was. Protein had more great effect on the sludge settleability than polysaccharide did. In the view of EPS in layers, the EPS in incompact outer layer(layer S) was the key to the formation of non-filamentous viscous bulking sludge(value of S-PN and SVI had the greatest correlation, r=0.881, P<0.05). Total contents of EPS components, the EPS contents in the different layers but tightly bond T-PN were all weak-negative correlated with SVI.
