| 摘 要： | 研究采用不另外占用土地的、以盘培多花黑麦草为主要内容的生态沟渠湿地来降解农村生活污水,并分析各项污染物指标在沟渠中的迁移变化。结果表明,设置盘培多花黑麦草的生态沟渠与自然沟渠相比,对生活污水中污染物中的氨态氮、总氮、总磷都有着较强的降解能力。靠近生活污水排水口处的300m生态沟渠内,各种污染物指标的降解幅度都较大,而远离排水口处的300m生态沟渠内,各种污染物指标的降解幅度都较小。

| Abstract: | This paper analyzed the changes of the contents of ammonic nitrogen,total nitrogen and total phosphorus in the water body along natural ditch and ecological ditch which was mainly composed of Lolium multiflorum stripes,also studied the retention and removal effects of ecological ditch on nitrogen and phosphorus.The results showed that the ecological ditch had stronger ability to degrade ammonic nitrogen,total nitrogen and total phosphorus in pollutants of rural domestic sewage than the natural ditch.In the ecological ditch with the length of 600m,the velocity of degrading pollutants near the entrance of rural domestic sewage was greater than that far away from the entrance. |
