摘要
通过对蔷薇湖净水型人工湿地运行监测,分析了湿地在2017年3月—2018年10月的运行情况。结果表明:蔷薇湖净水型人工湿地运行总体情况良好,COD_(Mn)、NH_(3)-N、TN、TP出水稳定达标,出水达到GB 3838—2002《地表水环境质量标准》中的Ⅲ类水标准,实现了对饮用水水源的有效净化。四季运行中,TN平均去除率均在60%以上,温度变化尚未影响去除效果。蔷薇湖净水型人工湿地中动/植物和微生物的协同作用,使得TN去除率稳定达标。
The water-purifying constructed wetland for the Qiangwei Lake protection was monitored, and the water quality data from March 2017 to October 2018 was analyzed and discussed. The results showed that the overall performance of the wetland was in good condition, and the effluent of COD_(Mn), NH_(3)-N, TN, and TP was stable and met the class Ⅲ in Environment Quality Standard for Surface Water(GB 3838—2002), which realized the effective protection of drinking water sources. The average total nitrogen removal efficiency was more than 60% during the operation period, from spring to winter. Even the change of temperature did not influence the nitrogen removal. The synergistic effect of plant/animal and microorganism in the Qiangwei Lake constructed wetland made the TN removal rate reach the standard stably.
