摘要

本研究旨在评估在地中海半干旱气候条件下，使用了 10 年的混合处理湿地 (TW) 系统对卡塔尼亚（意大利西西里岛东部）宜家®商场污水的去除效率和水力特性。该系统位于商店传统废水（WW）处理的下游，包括一个序批式反应器（SBR），然后是一个水平地下处理湿地（HF）单元和两个垂直地下流动处理湿地（VF1 和 VF2）单元。在 2016 年至 2023 年的 8 年期间，通过定期监测活动（大约每月一次）对经处理的污水中的化学、物理和微生物参数进行了评估。为测量以下参数收集了多达 72 个样本：总悬浮固体 (TSS)、生化需氧量 (BOD5)、化学需氧量 (COD)、总磷 (TP)、氨氮 (以 NH4 计)、硝酸盐 (以 NO3-N 计)、亚硝酸盐 (以 NO2-N 计)、总氮 (TN) 和大肠杆菌。对饱和时的水力传导性 (Ks) 进行了测量，并进行了示踪试验，以评估堵塞程度和高频装置内的水力行为特征。整个监测期间获得的结果显示了以下平均值和标准误差 (±) 去除效率范围（%）：TN21（±11）-80（±9）；TSS18（±42）-95（±3）；COD28（±23）-93（±2）；BOD5 31（±10）-85（±44）；TP14（±6）-49（±19）；NH4 50（±50）-95（±3）；E.大肠杆菌的平均减少量为 3.3（±0.2）-4.8（±0.4）乌洛格，在 2018 年以来分析的大多数样本中达到了不可检测值。该处理系统的功效是在国家和欧洲污水排放和中水回用标准监管框架的背景下进行评估的。Ks 值和示踪测试结果一致表明，高频装置的逐渐堵塞影响了该装置的水力行为，这对地中海地区 TW 的管理很有帮助。最后，性能结果还表明，整个处理过程不受高频装置堵塞的影响。

Long term performance of Nature-Based Solutions as decentralized wastewater treatment: a case study of a retail store in southern Italy

The aim of this study is to evaluate the removal efficiency and the hydraulic behavior of the 10-year-old hybrid treatment wetland (TW) system treating effluents of the IKEA® store of Catania (Eastern Sicily, Italy), under Mediterranean semi-arid climate conditions. The system is placed downstream to the conventional wastewater (WW) treatment of the store, that includes a sequential batch reactor (SBR) followed by a horizontal subsurface treatment wetland (HF) unit and two vertical subsurface flow treatment wetlands (VF1 and VF2) units. The assessment of chemical, physical, and microbiological parameters in treated WW was carried out through regular monitoring activities, occurring approximately on a monthly basis, over a 8-year period spanning from 2016 to 2023. Up to 72 samples were collected for the following parameters measurements: total suspended solids (TSS), BOD₅, COD, total phosphorus (TP), ammonia (as NH₄), nitrate (as NO₃-N), nitrite (as NO₂-N), total nitrogen (TN) and E. coli. Hydraulic conductivity at saturation (K_s) measurements and tracer tests were conducted to evaluate the extent of clogging and to characterize the hydraulic behavior within the HF unit. Results obtained during the entire monitoring period show the following mean and standard errors (±) removal efficiency ranges (%): TN 21(±11)-80(±9); TSS 18(±42)-95(±3); COD 28(±23)-93(±2); BOD₅ 31(±10)-85(±44); TP 14(±6)-49(±19); NH₄ 50(±50)-95(±3); E. coli was abated with a mean range of 3.3(±0.2)-4.8(±0.4) Ulog reduction, reaching not detectable values in most samples analyzed since 2018. The efficacy of the treatment system is assessed in the context of both national and European regulatory frameworks governing effluent discharge and water reuse standards. K_s values and tracer test results agree in showing the progressive clogging of the HF unit influencing the hydraulic behavior of the unit giving useful on the management of TWs in Mediterranean area. Finally, the performance results also indicate that the overall treatment is not affected by the HF unit clogging.

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
