摘要
磷元素过量易导致水体富营养化及影响水生动植物生长,因此对污水中磷的关注和控制尤为重要.人工湿地已成为从污水中除磷的一种绿色且经济的方法.综述了近年来人工湿地系统除磷的研究现状,包括去除机制、影响因素及强化措施.结果表明,人工湿地可以有效地去除水体中的大部分磷元素,其中去除机制涉及到物理、化学和生物等多种过程,如填料和植物的吸附、吸收和沉淀.人工湿地除磷的效率取决于填料吸附能力、湿地内氧环境、植物生长情况、气温及其他条件的影响.与生物、电化学和高级氧化等技术的组合是近年来人工湿地强化除磷的热点方向,但如何优化复杂条件下人工湿地系统除磷的性能参数,仍是一个亟需攻克的难题.需要进一步地研究来优化组合系统的性能,以确保它们的有效性和长期可持续性.
Excessive phosphorus can easily lead to the eutrophication of water bodies and affect the growth of aquatic plants and animals;therefore,it is particularly important to pay attention to and control phosphorus in sewage.Constructed wetlands have become a green and economical way to remove phosphorus from sewage.The research status of phosphorus removal in constructed wetland systems in recent years was summarized here,including the removal mechanism,influencing factors,and strengthening measures.The results showed that constructed wetlands could effectively remove most of the phosphorus in the water,and the removal mechanism involved physical,chemical,and biological processes,such as adsorption,absorption,and precipitation of fillers and plants.The efficiency of phosphorus removal in constructed wetland depends on the adsorption capacity of fillers,the oxygen environment in the wetland,plant growth,temperature,and other conditions.In recent years,the combination of biological,electrochemical,advanced oxidation,and other technologies has been the popular direction of enhanced phosphorus removal in constructed wetlands.However,how to optimize the performance parameters of phosphorus removal in constructed wetlands under complex conditions is still a difficult problem to overcome.Further research is needed to optimize the performance of the combined systems to ensure their effectiveness and long-term sustainability.
