摘　　要：人工湿地污水深度净化是污水再生的重要途径,对于缓解我国水资源短缺问题具有重要意义,符合减污降碳的双重需求。但人工湿地在实际工程运行中存在碳氧调控失衡导致的污染物去除和资源化水平低等瓶颈问题。微藻具有光合释氧、碳固定、污染物高效资源转化等优势,其与人工湿地具有高度互补性。详细分析了微藻与人工湿地不同耦合模式在碳氧调控机制、污染物去除与资源转化等方面的性能,解析了耦合系统的碳、氮、磷物质流,明确了人工湿地缺氧区适量补充微藻生物质的优化路径,从系统运行机制与效能等方面对该领域未来研究提出了展望。Reclaimed water could be achieved through advanced wastewater purification technology using constructed wetlands.Water reclamation by constructed wetlands can effectively alleviate the shortage of water resources and address both pollution reduction and carbon reduction needs.However,insufficient carbon/oxygen supplement leads to a low pollutant removal rate and low resource transformation rate,limits the scale-up application of constructed wetlands.Microalgae-based wastewater treatment offers several advantages,including photosynthetic oxygen release,carbon fixation,and efficient resource recovery of pollutants,which has high complementarity with constructed wetlands.This paper thoroughly compared the performance of two coupling modes of microalgae and constructed wetlands in the aspects of carbon/oxygen regulation of water purification mechanism,pollutant removal and resource transformation.The water purification process of the coupled system was analyzed from the perspective of carbon,nitrogen and phosphorus transformation,and the optimal path of adding moderate microalgae biomass in the anoxic area of constructed wetland was proposed.Finally,the paper outlined the future research in this field,focusing on system purification mechanisms and operation efficiency.
