摘要：

The aim of the current study is to evaluate the effectiveness of combined persulphate with hydrogen peroxide(S2O82/H2O2) oxidation as a post treatment of biologically treated POME (BIOTPOME) for the first time in literature. The removal efficiencies of COD, ammoniacal nitrogen (NH3N), and suspended solids (SS) were 36.8%, 47.6%, and 90.6%, respectively, by (SO82-)-O-2 oxidation alone under certain operation conditions (i.e., S2O82- = 0.82 g, pH 11, and contact time 20 min). Nevertheless, the combined process (S2O82-/H2O2) achieved 75.8% and 87.1% of NH3N, and SS removals, respectively, under 2.45/1.63 g/g H2O2/S2O82-, pH 11, and 20 min oxidation. Moreover, 56.9 of COD was removed at 56.9% at pH 8.4.
