本研究的目的是评估过硫酸盐与过氧化氢（S2 O 82-/H2 O2）氧化作为生物处理的棕榈油厂废水（POME）的后处理的有效性，首次在文献中。在一定的运行条件下（即，S2 O 82- = 0.82 g，pH 11，接触时间20 min）。在2.45/1.63 g/g H_2O_2/S_2O_8 ~（2-）、pH 11、氧化20 min条件下，S_2O_8 ~（2-）/H_2O_2组合工艺对NH_3-N和SS的去除率分别为75.8%和87.1%。pH值为8.4时COD去除率为56.9%。
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 palm oil mill effluent (POME) for the first time in the literature. The removal efficiencies of chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), and suspended solids (SS) were 36.8%, 47.6%, and 90.6%, respectively, by S2O82- 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% removals of NH3-N and SS, respectively, under 2.45/1.63 g/g H2O2/S2O82-, pH 11, and 20 min oxidation. Moreover, 56.9% of COD was removed at pH 8.4.
