This study investigated the effects of organic fraction of municipal solid waste (OFMSW) addition on the anaerobic treatment of the olive-mill pomace. Biodegradability of olive-mill pomace mixed with OFMSW was examined in anaerobic bioreactors. Only OFMSW was loaded in the first (control) bioreactor, while run 1 and run 2 bioreactors included different ratio of OFMSW and olive-mill pomace. COD, BOD(5), NH(4)-N, pH, VFA, CH(4) quantity and percentage in anaerobic bioreactors were regularly monitored. In addition, inert COD and anaerobic toxicity assay (ATA) were measured in leachate samples. The results of the study showed that 70% of OFMSW addition to olive-mill pomace has an advantage in terms of pollution parameters and methane generation. Since olive-mill pomace is not easy biodegradable, addition of high proportion of OFMSW promotes biodegradability of olive-mill pomace. Decreasing in BOD(5)/COD ratios in the run 1 and run 2 reactors carried out as 62 and 52%, respectively.
本研究考察了添加城市固体废物有机部分（OFMSW）对橄榄渣厌氧处理的影响。在厌氧生物反应器中研究了橄榄渣与 OFMSW 混合的可生物降解性。第一（对照）个生物反应器中仅加载 OFMSW，而运行 1 和运行 2 个生物反应器则包括不同比例的 OFMSW 和橄榄渣。定期监测厌氧生物反应器中的 COD、BOD(5)、NH(4)-N、pH、VFA、CH(4)量和百分比。此外，还测量了浸出液中的惰性 COD 和厌氧毒性测定（ATA）。研究结果表明，向橄榄渣中添加 70%的 OFMSW 在污染参数和甲烷生成方面具有优势。由于橄榄渣不易生物降解，因此添加高比例的 OFMSW 可促进橄榄渣的生物降解性。运行 1 和运行 2 反应器中的 BOD(5)/COD 比值分别下降到 62%和 52%。
