Floating treatment wetlands are small constructed rafts of wetland vegetation that are typically situated in small**bodies of water with poor water quality. The primary objective of floating treatment wetlands is to improve**water quality through natural mechanisms by introducing beneficial plants and microbes to surface water.**Ammonia is widely considered a key pollutant of concern in landfill leachate. Treatment wetlands may assist**in the removal of ammonia from water bodies through both physical and biological factors, including increased**oxygenation of water through downward root transport to facilitate the nitrification of ammonia to nitrate, by**forming a substrate for ammonia oxidizing microbial communities to colonize, and the direct uptake of**ammonia. While the the effectiveness of treatment wetlands in the reduction of ammonia in wastewater is**known, the specific application of floating treatment wetlands to reduce ammonia levels in landfill leachate**ponds has not yet been demonstrated. This project explores the role that floating treatment wetlands play in the**reduction of ammonia concentrations in a leachate pond

漂浮式处理湿地是由湿地植被组成的小型人工筏，通常位于水质较差的小型水体中。漂浮处理湿地的主要目的是通过自然机制，通过将有益的植物和微生物引入地表水来改善水质。氨被广泛认为是垃圾渗滤液中的主要污染物。处理湿地可通过物理和生物因素帮助 ** 去除水体中的氨，包括通过向下的根系运输增加 ** 水的氧化作用，促进氨硝化成硝酸盐，** 形成氨氧化微生物群落的基质，并直接吸收 ** 氨。虽然处理湿地在减少废水中氨含量方面的有效性是众所周知的，但漂浮处理湿地在减少垃圾渗滤液池塘中氨含量方面的具体应用尚未得到证实。本项目探讨了漂浮处理湿地在降低渗滤液池中氨浓度方面的作用
