  • 摘要: 构建美人蕉(Canna indicate L.)潜流人工湿地系统，对比研究基于模块化填料的人工湿地系统(MS-C-S)和基于普通碎石填料的人工湿地系统(GS-C-S)对农村生活污水的处理效果。结果表明，模块化填料对氨氮和总磷的去除率明显高于碎石填料。在MS-C-S和GS-C-S系统运行5 d后，MS-C-S系统对氨氮的去除率高达54.2%~69.4%，而GS-C-S系统仅为13%~28%；MS-C-S系统对总磷去除率77.7%~83.5%，而GS-C-S仅为54.5%。MS-C-S系统对氨氮和COD的去除率比 MS-U-S分别高出约23%和11%；而MS-C-S和MS-C-L系统对氨氮、总磷和COD的去除趋势和去除效果都几乎相近。模块化填料及以其为基质的人工湿地系统可以很好地去除氨氮、总磷和COD，有一定的应用前景。
    Abstract: In this study, a subsurface flow constructed wetland (SFCW) with Canna indicate L. plant was constructed to treat rural domestic sewage. In the SFCW, modular substrate (MS) was used to compare the treating effect with gravel substrate (GS). The results showed that the removal rates of NH4+-N and TP by canna constructed wetland system (MS-C-S) with modular substrate were significantly higher than those by common gravel substrate canna system (GS-C-S). After 5 day-operation, the removal rates of NH4+-N and TP by MS-C-S was 54.2%~69.4% and 77.7%~83.5%, respectively, while those by GS-C-S was only 13%~28% and 54.5%, respectively. The removal rates of NH4+-N and COD by the MS-C-S were about 23% and 11% higher than those by MS-U-S, respectively. MS-C-S and MS-C-L had similar removal trend and removal effect for NH4+-H, TP and COD. MS and MS-C-S had good performances on NH4+-H, TP and COD removal, and had a certain application prospect.
