Table olive processing wastewaters constitute a dangerous environmental problem in the Mediterranean countries because of their large volumes, high organic matter and salt concentration. The quantity and the characteristics of wastewaters produced, and thus, their environmental impact, varied depending on the season, varieties, soil and process employed. Several chemicals, biological and combined technologies have proven effective at bringing down organic pollution and toxicity of these effluents. Advanced oxidation processes have recognized as highly efficient treatments for the degradation of organic matter. Nonetheless, complete mineralization is generally expensive without salt removal. Biological processes are the most environmentally compatible and least-expensive treatment methods, but these operations do not always provide satisfactory results. This article surveys the current available technologies and suggests an effective, cheaper alternative for the recycling and the valorization of green table olives wastewaters.
由于其产量巨大、有机物和盐分浓度高，油橄榄加工废水在地中海国家构成了一个严重的环境问题。所产生废水的数量和特性，以及因此产生的环境影响，会因季节、品种、土壤和所采用的加工工艺而有所不同。几种化学、生物及联合技术已被证明在降低这些废水的有机污染和毒性方面是有效的。高级氧化工艺被认为是降解有机物的高效处理方法。然而，在没有脱盐的情况下，完全矿化通常成本高昂。生物工艺是最环保且成本最低的处理方法，但这些操作并不总是能产生令人满意的效果。本文综述了当前可用的技术，并提出了一种有效且更廉价的替代方案，用于绿橄榄废水的回收和增值利用。
