摘　　要：针对农田氮磷元素径流损失造成的农业面源污染,以浙江省某地块为例,采用生态沟渠+植草沟+生态浸没岛+雨水花园等组合式氮磷拦截技术对农业面源污染进行综合治理。项目运行结果表明:水质由《地表水环境质量标准》(GB 3838—2002)中劣Ⅴ类稳定提升为Ⅲ类标准,且具有无能耗、低投资、高效率等优点,项目的成功实施为类似农业面源污染治理提供了参考。In view of the non-point source pollution caused by the loss of nitrogen and phosphorus in farmland runoff, this study taken a plot of land in Zhejiang Province as an example, and adopts the combined nitrogen and phosphorus interception technology of ecological ditch + grass planting ditch +ecological immersion island + rain garden to comprehensively treat agricultural non-point source pollution. The operation results of the project show that the water quality had been steadily improved from Grade V to Grade IV in the Environmental Quality Standard for Surface Water(GB 3838—2002), and had the advantages of no energy consumption,low investment and high efficiency.The successful implementation of the project provides a reference for similar agricultural non-point source pollution control.
