| 中文摘要: |
| 生态浮床作为一种环境友好型的水污染治理方法，相对物理化学方法具有较大的优势，自提出以来越来越被广泛关注。目前，生态浮床技术在理论和应用方面都有较深入的研究，但主要集中在植物选择、污染物的去除效果和机理，以及各种创新型浮床，并未将生态浮床作为一个完整的微生态系统进行研究。本文根据植物和微生物的空间分布，模拟设置植物—微生物复合生态浮床系统，研究植物-微生物复合生态浮床、植物浮床和微生物对水质的净化效果，复合生态浮床内部植物和微生物间的相互作用、相互影响。结果表明，不同类型浮床对TP具有较好的去除效果。植物浮床和复合浮床对TP的去除效果均高达90%。复合浮床、植物浮床、微生物处理对水体TN的去除率分别为55.3%、31.2%、31.1%。植物、“植物+微生物”、“植物+空白载体”处理组对植物株高和地径的影响依次变大，主要原因是微生物在富集和形成初期，与植物之间存在养分竞争，影响植物的生长。 |

| Ecological floating beds are used as a water pollution controlling as well was an environment eco-friendly water treatment method. This technology is more advantageous compared to physical and chemical method. At present, there are a number of studies focusing on theoretical aspects as well as the applicability of ecological floating bed, but these studies mainly focused on plant selection, pollutants removal efficiency and mechanism of removal, however, it has never been studied as a whole microbial system.. Based on the spatial distribution of plants and microbes, the plant-microbial compound ecological floating bed system was set up to study the effect of plant-microbial interaction as a whole as well as individually; the interaction between plant and microbes in compound ecological floating bed, and how they affect each other. The results showed that the compound ecological floating bed was more effective towards the removal of TP (≤90%) whereas the removal rates of TN were 60.3%, 31.2% and 31.1%, in the floating bed, plant floating bed and microbial treatment, respectively. The main reason of effectual pollutant removal was the micro ecosystem formed by plants and microbes in a floating bed reactor. |
