摘要:
传统生态浮床用于水体净化时，存在植物种类选择单一、填料效果不理想、去除污染物效率低以及系统稳定性差等局限。通过选择优势种浮床植物和Mg-Al改性玉米秸秆生物炭填料（新型填料MACSB）来改进传统生态浮床，以提升其对富营养化水体的修复效果。结果显示，MACSB填料提高了系统的磷利用率和抑藻能力，且对植物生长无显著影响。植物组合-MACSB填料复合强化型生态浮床表现最佳，对TN、TP、COD和NH4+-N的去除率分别达到78.41%、96.83%、72.16%和99.54%，NO3--N积累情况也最为理想。高通量测序结果表明，引入优势种浮床植物组和MACSB填料均显著影响了水体微生物群落结构，并反映出各系统微生物群落结构的差异性。可见，通过改进生态浮床系统的设计，能够显著提升其对富营养化水体的修复效果。
Abstract:
Traditional ecological floating bed（EFB) has certain limitations when used for water purification, such as single plant species selection, unsatisfactory filling effect, low pollutant removal efficiency, and poor system stability. An enhancement of EFB was achieved by integrating dominant species and a novel Mg-Al modified corn straw biochar filler (MACSB), which significantly improved its efficacy in treating eutrophic water bodies. The MACSB filler not only improved phosphorus utilization and algae inhibition，but also did not adversely affect plant growth. The composite of plant combination and MACSB filler reached peak performance, with removal rates for TN, TP, COD and NH4+-N at 78.41%, 96.83%, 72.16% and 99.54%, respectively, while also achieving optimal NO3--N accumulation. High-throughput sequencing demonstrated that introducing dominant species and MACSB fillers markedly influenced the microbial community structure, highlighting distinct microbial profiles across different systems. Enhancements to the EFB design have significantly boosted its restoration capabilities.
