Meso-scale constructed wetlands have not been commonly used for the examination of interactions and operations within differently designed wetland systems. Sixteen meso-scale constructed wetland systems (4 operations with 4 replicates each) were therefore evaluated between November 2008 and June 2010. These systems were used to examine key operations identified in the literature including hydraulic loading rates, nutrient loading rates and nutrient recycling modes. The wetlands were managed in the following modes: normal, recycling, high nutrient loading and high flow rate. The designs were such that the influents could be varied at set loading rates and concentrations. The ammonia removal rates for the meso-scale integrated constructed wetland (ICW) systems were similar to other full-scale ICW systems that have been in operation in the south-east of Ireland for the past decade. These comparable results highlight the potential cost-effectiveness of these meso-scale experimental designs for the examination of novel operations for future ICW developments.
中观尺度人工湿地在考察不同设计的湿地系统内部相互作用和运行情况方面尚未得到广泛应用。因此，2008 年 11 月至 2010 年 6 月间对 16 个中观尺度人工湿地系统（4 种运行模式，每种各有 4 个重复）进行了评估。这些系统用于考察文献中确定的关键运行模式，包括水力负荷率、养分负荷率和养分再循环模式。湿地的管理模式包括正常、再循环、高养分负荷和高流速。设计时可以在设定的负荷率和浓度下改变进水。中观尺度综合人工湿地（ICW）系统的氨去除率与过去十年在爱尔兰东南部运行的其他全尺度 ICW 系统相似。这些可比结果突出了这些中观实验设计在考察未来 ICW 发展新运行模式方面的潜在成本效益。
