| 摘 要： | 为研究人工湿地对稻田氮磷污染的去除效应和规律,在广西青狮潭灌区选取农田洼地、废弃耕地改造为人工湿地,分别于2008、2009年水稻生育期在人工湿地进出水口采集水样进行氮磷浓度化验并分析.结果表明:2008年人工湿地对早稻和晚稻排水中TN、TP的去除率分别达到约26.5%、8.1%和53.0%、58.2%;2009年人工湿地对早稻和晚稻排水中TN、TP的去除率分别达到约56.0%、17.2%和64.1%、76.7%,能明显地改善农田排水水质.由此可见,选用人工湿地处理农田排水是合理可行的.

| Abstract: | In order to study removal effect and laws of constructed wetland to nitrogen and phosphorus pollutant of paddy drainage water,farmland depression and abandoned plowland were converted into constructed wetland in Qingshitan Irrigation Area,Guangxi Autonomous Region.Water samples of inlet and outlet of the constructed wetland were collected for nitrogen and phosphorus analysis during the whole rice growth period in 2008 and 2009.The results show that the removal rate of constructed wetland to early rice and l... |
