The aim of the current study is to evaluate the effectiveness of combined persulphate with hydrogen peroxide (SO/HO) 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 (NH-N), and suspended solids (SS) were 36.8%, 47.6%, and 90.6%, respectively, by SO oxidation alone under certain operation conditions (i.e., SO = 0.82 g, pH 11, and contact time 20 min). Nevertheless, the combined process (SO/HO) achieved 75.8% and 87.1% removals of NH-N and SS, respectively, under 2.45/1.63 g/g HO/SO, pH 11, and 20 min oxidation. Moreover, 56.9% of COD was removed at pH 8.4.
本研究的目的是首次在文献中评估过硫酸盐与过氧化氢（SO/HO）联合氧化作为生物处理后的棕榈油厂废水（POME）后处理方法的有效性。在特定操作条件下（即SO = 0.82 g、pH值为11且接触时间为20分钟），单独的SO氧化对化学需氧量（COD）、氨氮（NH-N）和悬浮固体（SS）的去除效率分别为36.8%、47.6%和90.6%。然而，在2.45/1.63 g/g HO/SO、pH值为11且氧化时间为20分钟的条件下，联合工艺（SO/HO）对NH-N和SS的去除率分别达到了75.8%和87.1%。此外，在pH值为8.4时，COD的去除率为56.9%。
