Abstract Constructed wetland (CW) works mostly depending on biological and biochemical processes. No doubt, these processes are affected by climate conditions. This is a challenge and that is why this review was made. By inspecting most of the published full-scale investigations of the CWs worldwide, it seems that the nitrogen is the most sensitive parameter to be affected in the cold climate, while organic matter and phosphorus remain relatively less affected. The low-temperature and oxygen shortcoming are together inhibited the biota activities. To face such situation, a wide range of possible intensification strategies from CW structure and operation related intensification (controlled tidal flow, batch operation, effluent recirculation, etc.) are discussed. Indeed, the effects of cold climate on CWs are an integrated issue without single solution. Future studies on the combination of multiple approaches and optimizing suitable microcosms as well as reasonable design and intensification considerations in cold climate CWs are necessary.

地下流人工湿地能否应用于寒冷气候地区？现有知识的回顾

摘要 人工湿地（CW）的工作主要依赖于生物和生化过程。毫无疑问，这些过程会受到气候条件的影响。这是一个挑战，这就是进行本次审查的原因。通过查看全球大部分已发表的 CW 全面调查，似乎在寒冷气候下，氮是受影响最敏感的参数，而有机物和磷的影响相对较小。低温和氧气的缺点共同抑制了生物群的活动。面对这种情况，从 CW 结构和与操作相关的强化（控制潮汐流、分批操作、污水再循环等）的各种可能的强化策略进行了讨论。确实，寒冷气候对 CW 的影响是一个综合问题，没有单一的解决方案。未来需要对寒冷气候 CW 中多种方法的组合和优化合适的微观世界以及合理的设计和强化考虑进行研究。
