ABSTRACT In this work, we explore the use of biochar as a remediation agent, and the sensitivity of the spectral‐induced polarization method as a remediation monitoring aid. Biochar amended columns were fully saturated with industrial wastewater (olive oil mill waste) with very high concentration of phenols (∼2485 mg/L) and other substances. The biochar‐amended columns achieved very high removal rates of phenols compared to the control (sand only). Geophysical monitoring over the duration of the experiment (10 days) showed changes in the spectral‐induced polarization signal (imaginary conductivity) consistent with phenol removal as confirmed by geochemical monitoring. This experiment confirmed the utility of biochar as a remediation agent. Furthermore, spectral‐induced polarization can serve as long‐term, high resolution, monitoring aid in organic contaminant degradation processes.

生物炭与光谱激发极化在污水处理中的应用初步评价

摘要在这项工作中，我们探索了使用 biochar 作为修复剂，以及光谱诱导极化方法作为修复监测辅助工具的灵敏度。Biochar 修正柱被工业废水（橄榄油厂废料）完全饱和，其中含有非常高浓度的苯酚（~2485 mg/L）和其他物质。与对照（仅砂）相比，生物炭改性柱实现了非常高的酚类去除率。实验期间（10 天）的地球物理监测显示光谱诱导极化信号（假想电导率）的变化与地球化学监测证实的苯酚去除一致。该实验证实了生物炭作为修复剂的实用性。此外，光谱诱导极化可以作为长期、高分辨率、
