Constructed wetlands (CWs) have been used as a green technology to treat various wastewaters for several decades. CWs offer a land-intensive, low-energy, and less-operational-requirements alternative to conventional treatment systems, especially for small communities and remote locations. However, the sustainable operation and successful application of these systems remains a challenge. Hence, this paper aims to provide and inspire sustainable solutions for the performance and application of CWs by giving a comprehensive review of CWs' application and the recent development on their sustainable design and operation for wastewater treatment. Firstly, a brief summary on the definition, classification and application of current CWs was presented. The design parameters and operational conditions of CWs including plant species, substrate types, water depth, hydraulic load, hydraulic retention time and feeding mode related to the sustainable operation for wastewater treatments were then discussed. Lastly, future research on improving the stability and sustainability of CWs were highlighted.
人工湿地（CWs）作为一种绿色技术，已经被用于处理各种废水几十年了。CWs 提供了一种土地密集型、低能源和低操作要求的替代传统处理系统的方法，特别是对于小型社区和偏远地区。然而，这些系统的可持续运行和成功应用仍然是一个挑战。因此，本文旨在通过全面回顾 CWs 在废水处理中的应用以及可持续设计和运行的最新进展，为 CWs 的性能和应用提供并激发可持续的解决方案。首先，简要总结了当前 CWs 的定义、分类和应用。然后讨论了 CWs 的设计参数和操作条件，包括与废水可持续处理相关的植物物种、基质类型、水深、水力负荷、水力停留时间和给料方式。最后，强调了未来提高 CWs 稳定性和可持续性的研究方向。
