Abstract

Due to the high organic load content, palm oil mill effluent (POME) has undergone various treatment systems. Most palm oil millers prefer to add a new approach to improve the existing treatment system but the investment and operation costs are too high to be incurred. Therefore, this study emphasizes the AB-101 microbial consortium performance in treating POME under the original operating parameters (0.2% AB-101 volume percentage, 7.5% molasses volume percentage and 100 ppm bio-activator dosage). The percentage reductions of POME characteristics under the original operating factor were 67.6% biochemical oxygen demand (BOD), 59.2% chemical oxygen demand (COD), 82.8% total suspended solids (TSS) and 66.7% oil and degrease (O&G). Meanwhile, POME treated with AB-101 under the optimal operating parameters (0.01% AB-101 volume percentage, 9.85% molasses volume percentage and 43.8 ppm bio-activator dosage) showed better characteristics of 92.9% BOD, 65.3% COD, 93.4% TSS and 95.5% O&G. Based on the proposed mechanism, lignocellulose degradation was greater when AB-101 was added into POME which improved the primary treatment of POME through enhanced anaerobic digestion.

用ab-101菌群处理果仁:性能和可能的机制

由于有机负荷含量高，棕榈油厂废水（POME）经过了各种处理系统。大多数棕榈油加工厂倾向于增加一种新的方法来改善现有的处理系统，但投资和运营成本太高，无法产生。因此，本研究强调了AB-101微生物群落在原始操作参数（0.2%AB-101体积百分比、7.5%糖蜜体积百分比和100ppm生物活化剂剂量）下处理聚甲醛的性能。在原始操作因子下，POME特性的降低百分比为67.6%的生化需氧量（BOD）、59.2%的化学需氧量（COD）、82.8%的总悬浮固体（TSS）和66.7%的油和脱脂（O＆G）。同时，在最佳操作参数（0.01%AB-101体积百分比、9.85%糖蜜体积百分比和43.8ppm生物活化剂剂量）下，AB-101处理POME的BOD、COD、TSS和O&G分别达到92.9%、65.3%、93.4%和95.5%。基于所提出的机理，当AB-101加入到聚甲醛中时，木质纤维素降解更大，这通过增强厌氧消化改善了聚甲醛的初级处理。
