The prospective of table olive debittering & washing Effluent (DWE) as feed stock wastewater for anaerobic digestion (AD) systems was investigated in batch and continuous systems together with cattle and pig manures. While DWE considered unsuitable for biological treatment methods due to its unbalanced nature, the co-digestion of the wastewaters resulted in a 50% increase in the methane production/gram volatile solids(added) (CH(4)/gVS(added)), accompanied by 30% phenol reduction and 80% total organic carbon removal (TOC). pH increase during the co-digestion period was not identified as an inhibitory factor and all reactors were able to withstand this operational condition change. Moreover, no volatile fatty acid (VFA) accumulation was observed, indicating that the reactors were not operating under stress-overloading state. Under thermophilic conditions a 7% increase on the TOC removal efficiency was achieved when compared to the mesophilic systems while, under mesophilic conditions phenolic compounds reduction was 10% higher compared to the thermophilic systems.
研究了橄榄苦苷脱苦及清洗废水(DWE)作为饲料废水用于厌氧消化(AD)系统的前景,研究中使用了牛和猪粪进行批式和连续系统实验。由于 DWE 的不平衡性质,其不适合生物处理方法,但废水的共消化导致甲烷产量/克挥发性固体(添加)(CH(4)/gVS(added))增加了 50%,同时苯酚减少了 30%,总有机碳去除率(TOC)提高了 80%。共消化期间 pH 值的增加并未被确定为抑制因素,所有反应器都能够承受这种操作条件的变化。此外,没有观察到挥发性脂肪酸(VFA)的积累,表明反应器没有在压力过载状态下运行。与中温系统相比,在高温条件下,TOC 去除效率提高了 7%,而在中温条件下,与高温系统相比,酚类化合物的去除率提高了 10%。
