The study explores a synergistic two-phase system to treat olive mill wastewater (OMW), comprising a multilayer adsorbent filter (pretreatment) and a vertical flow constructed wetland (VFCW). The pretreatment phase includes layers of commercial granular activated carbon (CGAC) and volcanic tuff (VT), while the VFCW phase consists of planted tank with Phragmites australis reeds and unplanted tanks. Initially, municipal wastewater is introduced into the VFCW to establish the required microbial community. Then, pre-treated OMW is passed through the VFCW. The removal rates of various pollutants were assessed. The planted VFCW showed superior removal efficiencies, averaging 97.82% for total chemical oxygen demand (COD), 92.78% for dissolved oxygen demand (COD), 99.61% for total phenolic compounds (TPC), 98.94% for total nitrogen (TN), 96.96% for ammonium, and 95.83% for nitrate. In contrast, the unplanted VFCW displayed lower removal efficiencies, averaging 91.47% for COD, 77.82% for COD, 98.53% for TPC, 97.51% for TN, 92.04% for ammonium, and 90.82% for nitrate. These findings highlight the significant potential of VFCWs, which offer an integrated approach to OMW treatment by incorporating physical, chemical, and biological mechanisms within a single treatment system.
该研究探索了一种协同两相系统来处理橄榄油厂废水（OMW），该系统包括一个多层吸附过滤器（预处理）和一个垂直流人工湿地（VFCW）。预处理阶段包括商业颗粒活性炭（CGAC）层和火山凝灰岩（VT）层，而VFCW阶段由种植有芦苇的种植池和未种植的池子组成。最初，将城市废水引入VFCW以建立所需的微生物群落。然后，将经过预处理的OMW通过VFCW。评估了各种污染物的去除率。种植的VFCW显示出更高的去除效率，总化学需氧量（COD）平均去除率为97.82%，溶解氧需求（COD）平均去除率为92.78%，总酚类化合物（TPC）平均去除率为99.61%，总氮（TN）平均去除率为98.94%，铵平均去除率为96.96%，硝酸盐平均去除率为95.83%。相比之下，未种植的VFCW去除效率较低，COD平均去除率为91.47%，COD平均去除率为77.82%，TPC平均去除率为98.53%，TN平均去除率为97.51%，铵平均去除率为92.04%，硝酸盐平均去除率为90.82%。这些发现突出了VFCW的巨大潜力，它通过在单一处理系统中整合物理、化学和生物机制，为OMW处理提供了一种综合方法。
