Abstract

Olive oil production is a source of huge amount of residuals knowns as OMW (Olive Mill Waste). The sustainable management and treatment of this waste is challenging due to presence of high amount of specific pollutants. The OMW is characterized by very high COD to BOD ratio with considerable content of polyphenols reaching up to 15g/l. Due to this, the biological utilization of OMW could be hindered or very slow when the conventional aerobic and anaerobic methods are used. In this study, the Microbial Electrolysis Cell (MEC) technology was applied as an alternative treatment approach. The method offers COD reduction and energy recovering in the form of hydrogen. The results demonstrated up to 65% efficiency in terms of COD and polyphenols removal which suggest that MEC, could be considered as an initial treatment stage in OMW utilization.

橄榄磨废料在微生物电解槽中的利用
橄榄油生产过程中会产生大量被称为OMW(橄榄磨坊废弃物)的残留物。由于存在大量特定污染物,这种废物的可持续管理和处理具有挑战性。其特点是COD / BOD比值很高,多酚类化合物含量较高,可达15g/l。因此,当采用传统的好氧和厌氧方法时,有机物的生物利用可能会受到阻碍或非常缓慢。本研究采用微生物电解电池(MEC)技术作为一种替代处理方法。该方法以氢的形式提供COD降低和能量回收。结果表明,在COD和多酚的去除方面,MEC的效率高达65%,这表明MEC可以被认为是OMW利用的初始处理阶段。
