摘要

本研究评估了一个试验性厌氧-好氧生物反应器（IAAB），用于处理有机负荷率（OLR）高达 30.0 gCOD/L.day的棕榈油厂废水（POME）。这项研究历时 118 天，旨在优化运行参数，以达到排放标准。该系统的有效性通过其降低生化需氧量 (BOD)、化学需氧量 (COD) 和总悬浮固体 (TSS) 的能力以及甲烷产量和工艺稳定性来衡量。结果显示去除率很高：BOD (99.95 %)、COD (99.58 %)和 TSS (99.24 %)，甲烷产量始终为 0.218 ± 0.032 LCH4/gCODremoved。这些结果证实，IAAB 有能力将出水水质保持在 BOD 低于 20 mg/L 的水平，符合马来西亚环境部 (DOE) 的标准，而无需调节 pH 值。这项研究证明，IAAB 能以稳定的性能和可观的沼气产量高效处理大量污染物负荷，是棕榈油行业可持续能源管理的可行解决方案。未来的研究将对联合消化工艺进行调查，以提高甲烷产量和经济可行性。

High organic loading rate treatment of palm oil mill effluent using a pilot-scale integrated anaerobic-aerobic bioreactor: A comprehensive performance study

This study evaluates a pilot-plant Integrated Anaerobic-Aerobic Bioreactor (IAAB) for treating Palm Oil Mill Effluent (POME) at a high Organic Loading Rate (OLR) of 30.0 gCOD/L.day. Conducted over 118 days, the research aimed to optimise operational parameters to meet discharge standards. The system’s effectiveness was measured by its ability to reduce Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS) alongside methane production and process stability. Results showed high removal efficiencies: BOD (99.95 %), COD (99.58 %), and TSS (99.24 %), with a consistent methane yield of 0.218 ± 0.032 LCH₄/gCOD_removed. These outcomes confirm the IAAB’s capability to maintain effluent quality with BOD under 20 mg/L, complying with the Department of Environment (DOE) Malaysia standards without pH adjustment. The study supports the IAAB’s efficiency in handling significant pollutant loads with stable performance and substantial biogas production, presenting it as a viable solution for sustainable energy management in the palm oil industry. Future research will investigate co-digestion processes to enhance methane yield and economic viability.
