减少农业面源污染物对水体的污染,对保障人民生命、生产活动具有重要意义.以余干县门前湖水体治理工程为例,采用面源污染生态拦截、尾水提升、湖区水质提升与水生态修复这种组合式的水生态修复技术进行水体模拟治理.计算结果表明,门前湖的面源污染大幅下降,各项污染物的年削减量分别为:化学需氧量503.23 t、氨氮27.09 t、总氮49.84t、总磷4.34t,水质得到明显提升,构建水生态系统,水体能够实现自净.所提组合式水生态修复技术对农业面源污染的治理具有明显的效用.
Reducing the pollution of agricultural non-point source pollutants on water bodies is of great significance for safeguarding people's lives and production activities.Taking the Menqian Lake water body treatment project in Yugan county as an example,a combination of water ecological restoration technologies,including non-point source pollution ecological interception,tail water improvement,lake area water quality improvement,and water ecological restoration,is adopted for water body treatment.The calculate results show that,the non-point source pollution of Menqian Lake has significantly decreased,and the annual reduction amounts of various pollutants are:chemical oxygen demand 503.23 t,ammonia nitrogen 27.09 t,total nitrogen 49.84 t,and total phosphorus 4.34 t.The water quality has been significantly improved,and the water body can achieve self-purification.The combined water ecological restoration technology proposed on the surface has a significant effect on the treatment of agricultural non-point source pollution.
