浮水植物型人工湿地对水稻田排水中氮磷污染的控制效果
Control Effect of Floating Plants Constructed Wetland to Nitrogen and Phosphorus Pollution from Rice Field Drainage
摘要
Abstract
[ Objective ] The control effect of floating plants constructed wetland to nitrogen and phosphorus pollution from rice field drainage was studied. [Method]Firstly,the characteristic of floating plants and the purification principle of pollutants were introduced,and then purification effect was analyzed through controlling nitrogen and phosphorus pollution from rice field drainage by floating plants constructed wetland. [ Result] By means of floating plants constructed wetland, the average removal rate of total nitrogen (TN) from double - season early and late rice field drainage reached 52.17％ and 62.23％, while that of total phosphorus was 45.69％ and 74.37％ ,respectively,with better removal effect. Meanwhile, floating plants have ecological and ornamental value to some extent. [ Conclusion ] Floating plants constructed wetland could not only control nitrogen and phosphorus pollution from field drainage effectively but also keep farmland ecosystem in healthy state.关键词
