生物滞留设施植物·填料·微生物研究进展

Research Progress of Plant,Filler,Microorganism in Bioretention

总结了生物滞留设施对污染物质的净化效果与机制;从生物滞留系统植物选择、填料优化、高效微生物筛选3个方面论述了国内外主要研究进展和成果。结合植物的选择原则和作用,对植物进行了归类对比和区域划分;讨论了现有填料的组成及不足,提出了填料的优化措施;归纳了重金属和有毒有机物高效降解菌的筛选情况,以推动应用微生物技术在生物滞留系统中的研究。

The purification effect and mechanism of bioretention facilities on pollutant were sum up. The main achievements at home and abroad of bioretention system were discussed from three aspects, including plant selection, packing optimization, and efficient microbial screening. The classification comparision and regional classification of plants were carried out according to the principles and functions of plant selection. Composition and shortcomings of the existing fillers were discussed, and the optimization measures of filler were proposed. The screening situation of efficient degrading bacteria of heavy metals and toxic organic compounds were summarized in order to promote the research of microbial technology in the bioretention system.
