人工湿地(CW),一个有希望的,对环境负责,和有效的绿色生态治理技术,积极参与各种形式的废水处理。低温会,然而,导致包括植物休眠在内的问题,微生物活性降低,和CW中的冰形成,这将影响CWs处理废水的效果。在寒冷地区成功连续应用CW是极其困难的。因此,这是至关重要的找到解决方案,以提高CWs的能力,处理废水在低温下的紧迫问题。这篇综述的重点是寒冷气候对CW(植物,基材,微生物,污染物的去除效果)。它精心概述了当前在低温条件下提高CW性能的策略,包括内部组件的改进和优化的修改(即,植物和基质选择,生物增强)和增强CW的外部操作条件(如工艺组合,废水再循环,曝气,保温,和运行参数优化)。最后,展望了未来可能加强CW在寒冷气候下表现的潜在研究方向和技术创新的前景。这篇综述旨在为运营战略提供有价值的见解,广泛实施,以及随后在较冷气候地区的CW研究。
Constructed wetland (CW), a promising, environmentally responsible, and effective green ecological treatment technology, is actively involved in the treatment of various forms of wastewater. Low temperatures will, however, lead to issues including plant dormancy, decreased microbial activity, and ice formation in CWs, which will influence how well CWs process wastewater. Applying CWs successfully and continuously in cold areas is extremely difficult. Therefore, it is crucial to find solutions for the pressing issue of increasing the CWs\' ability to process wastewater at low temperatures. This review focuses on the effect of cold climate on CWs (plants, substrates, microorganisms, removal effect of pollutants). It meticulously outlines current strategies to enhance CWs\' performance under low-temperature conditions, including modifications for the improvement and optimization of the internal components (i.e., plant and substrate selection, bio-augmentation) and enhancement of the external operation conditions of CWs (such as process combination, effluent recirculation, aeration, heat preservation, and operation parameter optimization). Finally, future perspectives on potential research directions and technological innovations that could strengthen CWs\' performance in cold climates are prospected. This review aims to contribute valuable insights into the operation strategies, widespread implementation, and subsequent study of CWs in colder climate regions.
