Phosphorus Removal Mechanism of Granular Sludge with Yellow Water as Carbon Source Study |
| |
| Abstract: | Granular sludge ,as a biological treatment technology concerned in recent years ,has compact structure ,good settling ability and perfect biological activity .In order to understand the mechanism of phosphorus removal of aerobic granu-lar sludge which is fed by the yellow water ,the physical characteristics and the phosphorus removal characteristic of granular sludge are seriously studied ,especially the shape and content of phosphorus in granular sludge .Meanwhile the different ex-traction methods and the effects on the phosphorus removal of extracellular polymeric substances (EPS ) are also studied .The phosphorus removal mechanisms of granular sludge are described ,which provides theoretical and technical support for the realization of high efficiency and low consumption phosphorus removal in urban sewage using granular sludge for simultaneous removal of nitrogen and phosphorus . |
