| 摘 要： | 人工湿地作为一种低耗高效的污水处理系统正在被广泛应用于各种类型的污水处理,不仅对有机污染物有较强的降解能力,而且对传统的二级处理难以去除的氮磷也有较好的去除效果。人工湿地污水处理系统是一个复合生态工程系统,其对污染的去除机理是一个错综复杂的过程,基质、水生植物和微生物共同发挥着重要作用。综述了人工湿地脱氮除磷的效果与机理,讨论了基质、水生植物、微生物及其他外界因素对系统处理效果的影响及氮磷去除的预测模型,提出了当前人工湿地研究中存在的问题和提高人工湿地脱氮除磷能力的对策。

| Abstract: | Constructed wetlands, as a kind of wastewater treatment technology with high efficiency and low costs, are widely used to treat different type wastewater, They can degrade organic pollutants effectively, and have the capability to remove nitrogen (N) and phosphorus (P) difficult to remove by secondary treatment. Constructed wetlands are integrated eco-engineering systems and their pollutant removal functioning are also complex processes, in which substrate, aquatic plants and microorganism play the important role together. This paper illustrated the efficiency and functioning of N and P removal in constructed wetlands, discussed about the effects on treatment efficiency from substrate, aquatic plants, microorganism and other external factors and about the kinetic models predicting N and P removal performances, brought forward the problems in current studies on N and P removal in constructed wetlands and proposed several solutions to improve N and P removal capability. |
