摘要
针对辽河流域农田面源污染现状,提出几种农田面源污染控制技术,包括源头控制的科学施用化肥和合理使用农药、采取畜禽养殖粪污处理工程,过程削减的植被缓冲带技术、生态沟渠拦截技术和生态塘技术,末端治理的人工湿地技术和多水塘技术.上述研究为有效控制农田面源污染,保护辽河水体资源提供技术支撑.
According to current situation of Liaohe river basin irrigation and non-point source pollution, and puts forward several kinds of farmland non-point source pollution control technology, including source control of scientific application of fertilizer and the rational use of pesticides, livestock and poultry breeding waste treatment engineering, process to cut the vegetation buffer technology, ecological ditch intercept technology and ecological pond, governance at the end of the constructed wetland technology and multiple ponds. The above research provides technical support for effectively controlling farmland non-point source pollution and protecting water resources of Liaohe river.
