中文摘要:
      为提升生态浮床对水体的净化效果,以无碳填料为对照,选用生物质碳源(玉米芯)与沸石制备碳源复合填料,分别添加到菖蒲+旱伞草、美人蕉+旱伞草、美人蕉+菖蒲3种植物组合构建的组合生态浮床中,以研究生物质碳源复合填料生态浮床对氮、磷和有机物的去除效果及浮床植物的生长特性。结果表明:复合碳源填料对促进植物生长和提升生态浮床的净化效果有重要作用。加碳源组合中植物的平均生长速度和生长量整体优于无碳组合。加碳源组合浮床对NH4+—N、NO3-—N、TP、COD的平均去除率分别为73.0%、88.7%、54.4%、58.7%,较相应的无碳组合去除率提高了6.9%,5.0%,18.4%,-22.3%。加碳源组合中的“菖蒲+旱伞草”组合对NH4+—N、NO3-—N、TP的去除率分别达到76.6%、92.6%、60.7%,均高于“美人蕉+菖蒲”、“美人蕉+旱伞草”组合生态浮床的去除率。推荐生物质碳源与“菖蒲+旱伞草”组合生态浮床用于水体原位修复。
英文摘要:
      In order to improve the purification effect of ecological floating beds, the carbon source composite fillers with corncob and zeolite were applied to three plant assemblages, i.e. Acorus calamus L. + Cyperus altenifolius, Canna indica L. + Cyperus altenifolius, and Canna indica L. + Acorus calamus L.. With the non-carbon fillers as the control, we investigated the removal effect of nitrogen, phosphorus and organic matter by the biomass carbon source composite fillers, as well as the growth characteristics of the plants. The results showed that the composite carbon source filler played an important role in the purification process of the floating beds and enhanced the plant growth. The average growth rate and quantity of all three plant assemblages with carbon source composite fillers were better than those with non-carbon fillers in general. The average removal rate of ammonia nitrogen (NH4+—N), nitrate nitrogen (NO3-—N), total phosphorous (TP) and chemical oxygen demand (COD) by these three plant assemblages were 73.0%, 88.7%, 54.4% and 58.7%, respectively, which were improved by 6.9%, 5.0%, 18.4% and -22.3% respectively, compared to those of the non-carbon fillers. The assemblage of Acorus calamus L. + Cyperus altenifolius with a biomass carbon source filler could remove NH4+—N、NO3-—N、TP by the average rate of 76.6%, 92.6%, and 60.7% respectively, which was evidently better than the removal result of Canna indica L. + Acorus calamus L., and Canna indica L. + Cyperus altenifolius. Therefore, the assemblage of Acorus calamus L. + Cyperus altenifolius with a biomass carbon source filler is recommended for the in-situ water restoration.
