摘要

本研究旨在确定人工湿地(CWs)对高浓度氨磷城市污水中介质污染物的去除效率。这项研究利用了以前发表在可靠来源的研究中的二手数据。比较了泥炭香蒲、香蒲、泥炭、Viteveria zizanioides和芦苇对人工湿地的去除率。结果表明,含紫花vitveria zizaniode的CWs处理效果最佳,平均除氮率为84%,除磷率为86%。泥炭还具有降低pH值的作用。泥炭苔藓中的腐植酸和黄腐酸在碱性条件下的水环境中可以快速释放,有效降低pH值。紫花vitveria zizaniode与泥炭的组合使用显著提高了高浓度氨磷城市污水的污染物去除效率。

Nitrogen and Phosphorus Removal of Wastewater via Constructed Wetlands Approach
This study aimed to determine the efficiency of media pollutant removal from municipal wastewater with high concentrations of ammonia and phosphorus in constructed wetlands  (CWs). The study utilized secondary data from previous studies that were published in credible sources. The removal efficiencies of the five media used in the constructed wetland, namely, peat-cattails, cattails, peat, Viteveria zizanioides, and Phragmite karka, were compared. The results showed that CWs with Viteveria zizaniode exhibited the best performance on average, removing 84% nitrogen and 86% phosphorus. Peat was also effective in attenuating pH. Humic and fulvic acids in peat moss can be released quickly in an aqueous environment under alkaline conditions, effectively lowering the pH value. The combination of Viteveria zizaniode and peat significantly improved pollutant removal efficiency in municipal wastewater with high concentrations of ammonia and phosphorus.
