摘要

在本研究中，采用多种预处理方法来提高三相系统运行的橄榄油厂卧螺器出口收集的橄榄油厂废水（OMW）的沼气生产效率。考察了超声波（US）、化学（HNO₃）、微波（MW）及其组合对OMW厌氧消化的影响。虽然单独的HNO₃预处理和与其他方法相结合提高了沼气生产效率，但单独的MW预处理显着降低了沼气产量。在混合HN20 + US10预处理样品中，最大体积累积沼气产量为231.5 mL (1.78 mL沼气/gVSd)，其中HNO₃在原料OMW中占总固体量的20%，然后进行US预处理10分钟。HN20 + US10预处理样品的总酚和化学需氧量（COD）去除率分别为25.9%和77.2%。

Enhancing biogas production efficiency through physical, chemical, thermal, and hybrid pre-treatment of olive mill wastewater

In this study, various pre-treatment methods were applied to enhance the biogas production efficiency of olive mill wastewater (OMW) collected from the decanter outlet of an olive oil mill operating with a three-phase system. The effects of ultrasonic (US), chemical (HNO₃), microwave (MW), and their combinations on the anaerobic digestion of OMW were evaluated. While HNO₃ pre-treatment alone and in combination with other methods improved biogas production efficiency, MW pre-treatment alone significantly reduced biogas yield. The highest volumetric cumulative biogas production of 231.5 mL (1.78 mL Biogas/gVSd) was achieved in the hybrid HN20 + US10 pre-treated sample, where HNO₃ was applied at 20 % of the total solids in raw OMW, followed by US pre-treatment for 10 min. The total phenol and chemical oxygen demand (COD) removal percentages for the HN20 + US10 pre-treated sample were determined as 25.9 % and 77.2 %, respectively.
