Integrated Constructed Wetlands (ICWs) are potentially effective tools in the effort to restore aquatic ecosystems, and also they incorporate multiple co-benefits. An ICW was constructed in Norfolk, UK, to address the degradation of a stream and lake receiving treated effluent from a small Sewage Treatment Works (STW). Results demonstrated that: (1) nutrient concentrations significantly reduced from the ICW influent to the effluent (percentage reductions: total phosphorus [TP]: 78%, orthophosphate: 80%, total oxidised nitrogen [TON]: 65%, nitrate: 65%, nitrite: 67%, ammoniacal nitrogen: 62%), and mean dissolved oxygen concentrations increased (influent mean: 6.4 ± 1.4 mg l⁻¹ effluent mean: 17.8 ± 3.3 mg l⁻¹), (2) there were non-significant reductions in nutrient concentrations in the receiving stream (percentage reductions: TP: 23%, orthophosphate: 23%, TON: 26%, nitrate: 26%), with the exception of ammoniacal nitrogen (127% increase) and nitrite (76%) after ICW commissioning, and (3) mean in situ avian species richness increased from 10 to 27 species. Thus, the ICW substantially reduced nutrient concentrations, and had in situ conservation benefits. It is recommended that appropriately designed ICWs should be implemented widely and statutory authorities should ensure: 1) best-practice maintenance and 2) final effluent monitoring at both the STW and at the ICW outflows.

综合人工湿地（ICW）是努力恢复水生生态系统的潜在有效工具，并且它们具有多种共同利益。在英国诺福克郡建造了ICW，以解决从小型污水处理厂（STW）接收处理后废水的溪流和湖泊的退化。结果表明：（1）从ICW进水到出水的养分浓度显着降低（百分比降低：总磷[TP]：78％，正磷酸盐：80％，总氧化氮[TON]：65％，硝酸盐：65％ ，亚硝酸盐：67％，氨氮：62％）和平均溶解氧浓度增加（进水平均值：6.4±1.4 mg l ^-1出水平均值：17.8±3.3 mg l ^-1），（2）接收流中营养物质的浓度没有显着降低（百分比降低：TP：23％，正磷酸盐：23％，TON：26％，硝酸盐：26％），氨氮除外（ ICW调试后增加了127％）和亚硝酸盐（增加了76％），（3）平均原位禽类的丰富度从10种增加到27种。因此，ICW大大降低了养分浓度，并具有就地保护的好处。建议适当设计的ICW应广泛实施，并且法定机构应确保：1）最佳实践维护和2）STW和ICW流出处的最终废水监测。
