Effect of carbon substrates on the characteristics of activated sludge flocs
|
Abstract:
The floc characteristics of activated sludge flocs fed with glucose,starch,acetate and phenol substrates were investigated.The polysaccharide content in the sludge fed with glucose was lower than the others,while the protein content in the sludge fed with phenol was the highest of the group.The total amount of EPS in the sludge fed with phenol was higher than the others.The ratio of polysaccharide to protein was correlated with the surface charge of the sludge flocs.The functional groups of EPS in the sludg...
