摘要
汉石桥湿地是北京市仅有的几个自然湿地之一,其核心区域承载了贾家河及蔡家河流域的污水净化及雨洪调蓄等功能。本文通过长期对汉石桥湿地净化效果的监测,发现湿地对于氨氮、总磷、总氮的去除较高。冬季寒冷水生植物代谢降低使各项污染物的净化能力明显下降,导致湿地的净化稳定性不足。研究显示湿地核心区水体未对相邻地表水造成污染。
Hanshiqiao Wetland is one of the few natural wetlands in Beijing,with its core area carrying out functions such as sewage purification and rainwater storage in the Jiajia River and Caijia River basins.Through long-term monitoring of the purification effect of Hanshiqiao Wetland,it was found that the wetland has a high removal rate for ammonia nitrogen,total phosphorus,and total nitrogen.The purification capacity of various pollutants is significantly reduced in winter due to the decrease in metabolism of aquatic plants in cold weather,resulting in insufficient purification stability of the wetland.The research shows that the water in the core area of the wetland does not cause pollution to adjacent surface water.
