摘要

液体橄榄废料是橄榄油生产国环境面临的主要问题之一。我们的目标是找出能减少对环境影响的压榨方法，特别是在有机负荷和微生物污染方面，以指导未来的处理和回收战略。化学需氧量（COD）结果显示，连续三相系统的 COD 值最高，达到 31 × 104 毫克 O2/升，多酚浓度为 13 × 103 毫克/升，羟基酪醇浓度为 2137.4 毫克/升。微生物研究显示，三种方法中都存在酵母、真菌和细菌。两相法的微生物量最高，含氮化合物的浓度也很高。从保护环境的角度来看，两相法与其他方法相比污染最小。

Assessment of the impact of the three different methods of crushing olives on the microbiological and physicochemical properties of wastewater in olive mills

Liquid olive waste presents one of the major problems for the environment in olive oil-producing countries. The goal is to identify the crushing method that decreases the environmental impact, particularly in terms of the organic loading and microbial contamination to guide the future treatment and recovery strategies. The results obtained from the chemical oxygen demand (COD) have shown that the continuous three-phase system exhibited the highest COD value, reaching 31 × 10⁴ mg O₂/l, and a concentration of 13 × 10³ mg/l for polyphenols and 2137.4 mg/l for hydroxytyrosol. The microbiological study is yeasts, fungi, and bacteria in the three methods. The two-phase method had the highest microbial load with great concentrations of nitrogenous compounds. As a result of the preservation of our environment, we see that the two-phase method represents the least polluting method, compared to the other methods.

期刊介绍： Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
