摘要
人工湿地工艺作为一种优选技术应用于流域规模的污染水处理。在此,根据人工湿地中常用填料和植物的物理、化学属性,分析其优缺点及适用性,总结出对氮、磷和COD处理效果较好的填料和植物,并提出了一系列综合优化的措施和建议。
As a optimize technic, the constructed wetland is applied on wastewate treatment in drainage ares. According to the physical and chemical attributes of the padding and plant which are usually used in the constructed wetland, this article analyzed their advantages, disadvantages and applicability, summarize the better processing effect of the nitrogen, the phosphorus and the COD in the constructed wetland and gave a series of syntheses optimize measure and suggestion.
