Olive mill wastewater (OMW) is the by-product of olive oil industrial production. It is characterized by a dark brownish color and a strong odor and is considered one of the most polluted agricultural wastes. In this paper we briefly describe an innovative procedure for the depuration of olive mill wastewater. With this procedure it is also possible to recover valuable substances such as phenolic compounds which have important commercial applications: they can be used in the prevention of cardiovascular disease and as antiviral, antioxidant and antitumor agents. The proposed OMW treatment uses two different packed vegetable matrices which remove most of the pollutant substances by absorption. After filtration of OMW on the matrices the pollutant load of the waste is greatly reduced: the organic content (COD) is reduced more than 80% and the phenol compounds are completely removed.
橄榄油厂废水（OMW）是橄榄油工业生产的副产品。它的特点是呈深褐色且气味浓烈，被认为是污染最严重的农业废弃物之一。在本文中，我们简要描述了一种用于净化橄榄油厂废水的创新方法。通过这种方法，还能够回收具有重要商业应用价值的物质，如酚类化合物：它们可用于预防心血管疾病，还可作为抗病毒、抗氧化和抗肿瘤剂。所提出的橄榄油厂废水处理方法使用了两种不同的填充植物基质，通过吸附去除大部分污染物质。在基质上对橄榄油厂废水进行过滤后，废弃物的污染物负荷大幅降低：有机物含量（化学需氧量）降低超过80%，酚类化合物被完全去除。
