This work aims to monitor inorganic nutrients (phosphorus and ammonium) behavior during the injection of Olive Mill Wastewater (OMWW) in an activated sludge process. The system was fed firstly with urban wastewater (UWW) and was alimented after its stabilization with OMWW (at 0.1% (v/v) and 1%) for 100 days. Total polyphenols, chemical oxygen demand (COD), nutrients, and biomass behavior against OMWW injection were investigated. The results showed a satisfactory biomass growth of 7.12 g.L and a high microbial activity of 21.88 mg O.g.h. An overall removal reached 90%, 92%, 59% and 93% respectively for, COD, total polyphenols, PO and NH. Adding OMWW at 1% seems to improve the nutrients elimination, especially phosphorus by the biological process probably though bringing more biodegradable organics. The chemical processes (precipitation/complexation) could also be involved in phosphorus removal, due to the OMWW wealth on salts elements such as calcium.
本工作旨在监测在活性污泥工艺中注入橄榄厂废水（OMWW）期间无机营养物（磷和氨）的行为。该系统最初以城市废水（UWW）为食，在其稳定后用 OMWW（0.1%（v/v）和 1%）进料 100 天。研究了总多酚、化学需氧量（COD）、营养物和生物量对 OMWW 注入的行为。结果表明，生物量的生长令人满意，达到 7.12 g.L，微生物活性高，达到 21.88 mg O.g.h。总体去除率分别达到 90%、92%、59%和 93%，分别为 COD、总多酚、PO 和 NH。以 1%的比例添加 OMWW 似乎可以通过引入更多可生物降解的有机物来改善营养物的去除，特别是磷。由于 OMWW 富含钙等盐类元素，化学过程（沉淀/络合）也可能参与磷的去除。
