| 摘 要： | 农田排水导致的面源污染是灌区水环境恶化的重要原因之一。为寻找适合南方地区的治理办法,提出了运用排水沟与塘堰湿地结合的系统净化农田排水水质,并在江西省灌溉试验中心站开展了系统的试验研究。结果表明,该系统具有良好的净污效果,对TN、NH4+-N、NO3--N和TP的综合去除率分别为69.8%、88.1%、69.6%、81.2%,一定程度上实现了减少农田面源污染和修复农田水环境的目的。

| Abstract: | Non point source pollution caused by drainage water of farmland is one of the main reasons for deterioration of water environment in irrigation district. In order to find out harnessing measurements fitting for agricultural farmlands of South China, the joint system of drainage ditches and pond wetlands is proposed to purify farmland drainage water quality. And then the systemic experiments are conducted in Jiangxi Central Irrigation Experiment Station. Experiment results show that the drainage ditches and natural wetlands has satisfactory effects in pollution control; the reduction rate of TN, NH4+ N, NO 3 N and TP are reduced 69.8%, 88.1%, 69.6% and 81.2%, respectively. According to the experimental result, it reduces non point source pollution of farmlands and repairs water environment of farmlands in some degree. |
