人工湿地技术以其独特的低能耗、低成本的优势，被广泛应用于城市二级污水的处理。在过去的几十年里，CW在处理农业径流和农业工业废水方面越来越受欢迎。本综述强调了湿地技术的实践、应用和研究，将其置于需要可靠和可持续的解决方案来管理农业径流和农工废水的总体背景下。湿地系统去除各种污染物的重要性，农业的性能和有效性的关键评估。同时，对影响污水处理系统去除污染物效果的设计参数和运行条件进行了讨论。适当的预处理，人工曝气，污水再循环，串联设计，和微生物动力学的作用，对增强处理。农业处理湿地的未来研究的挑战和前景也得到了解决。
With the unique advantages of cost-effectiveness and low energy consumption, constructed wetlands (CWs) are commonly used for treatment of secondary municipal wastewaters. Over the last decades, CWs have gained increased popularity for treating agricultural runoff and agro-industrial wastewater. This review highlights the practice, application, and research on wetland technology, placing them in the overall context of the need for reliable and sustainable solutions to managing agricultural runoff and agro-industrial wastewater. A critical assessment of the performance and effectiveness of wetland systems for removing various contaminants of importance to agriculture is presented. The design parameters and operational conditions affecting the efficiency of contaminant removal in CWs receiving agricultural runoff and agro-industrial wastewater are also discussed. The role of proper pretreatment, artificial aeration, effluent recirculation, in-series design, and microbial dynamics on the enhancement of treatment is provided. Challenges and perspectives for future research on agricultural treatment wetlands are also addressed.
