Extracellular Polymeric Substances Disintegration by Fenton Oxidation of Excess Sludge
|
Abstract:
Fenton oxidation was used to disintegrate extracellular polymeric substances(EPS)of excess sludge with its strong oxidation ability.The concentration of polysaccharide,protein and the change of soluble chemical oxygen demand(SCOD)disintegrated from EPS represent the EPS disintegration degree.The objective of this study is to optimize the operational conditions for EPS disintegration with Fenton oxidation.It is shown that the optimal operational condition is as following:pH=2.5,reaction time = 90min,H_2O_2/F...
