复合型人工湿地对抚仙湖入湖河道污水中氮的去除

Nitrogen Removal by Integrated Constructed Wetland in the Rivers Following to Fuxian Lake

在抚仙湖北岸构建复合型人工湿地污水处理系统,对窑泥沟入湖河道污水中氮的去除效果进行了试验研究,结果表明,系统水力负荷年平均为37mm/d,氮负荷年平均为3．315g/m^2·d,对污水中NOx、NH_4^+、TON和TN去除率年平均分别为62．7%、53．8%、62．4%和57．5%。

Research on nitrogen removal in Yaonigou river by integrated constructed wetland wastewater treatment system is experimented. The results show that the average hydrologic budget is 37 mm per day and the average nitrogen loading is 3. 315g/m^2. d. The average removal of nitrogen oxides, ammonia nitrogen, organic nitrogen and total nitrogen are 62.7 %, 53.8%, 62.4% and 57.5% respectively.
