Oxidation Behavior of Stable-Oxidative-Poly-Si-Fe (SOPSF) Coagulant
The oxidation behavior of a stable-oxidative-poly-Si-Fe (SOPSF) coagulant prepared by water glass and H2SO4 solution in treating a synthetic humic acid (HA) water was probed,in compraison with that of poly-Si-Fe (PSF) and Polyferric aluminum (PFA).The results revealed that the oxidization of SOPSF and PSF was very stable during the whole coagulation process,and played a role during the whole process including quiescent settling stage.While PFA almost gave no oxidization even at higher dose of 0.322 mrno1.L-1.The oxidization rate of SOPSF was slower than that of SOPSF hydrolysis and destabilization process.Coagulation mechanism of SOPSF in removing dissolved organic matters (DOMs) may be a comprehensive results between the alternating interaction of oxidization/adsorption-destabilization/oxidization,bridging and sweeping.
