辽河流域农田面源污染控制技术模式

针对辽河流域面源污染情况,结合国内外研究现状,提出几种农田面源污染治理技术模式,包括源头控制的科学施肥用药技术和畜禽养殖污染源治理;过程削减的生态拦截缓冲带、生态田埂、生态沟渠、稳定塘和氧化沟技术;末端治理的人工生态塘和人工湿地技术以及综合治理技术。研究结果为有效控制农田面源污染,保护辽河流域水资源提供技术支撑。

According to the situation of non-point source pollution in Liaohe river basin and combined with the current research situation at home and abroad,several technical models of non -point source pollution control in farmland were put forward,including scientific fertilization and drug control technology in source control and pollution source control in livestock and poultry breeding;process reduction of ecological interception buffer zone,ecological ridge,ecological ditch,stabilization pond and oxidation ditch technology;end treatment of artificial ecological pond and constructed wetland technology,as well as comprehensive treatment technology. The results provide technical support for effectively controlling farmland non-point source pollution and protecting water resources in Liaohe river basin.
