生物滤池地下水除铁除锰研究进展

摘要

In many processing technologies,biological aerated filter,due to its low operation cost,simple operation,simultaneous removal of iron and manganese and other substances’ is widely used in removal of iron and manganese from groundwater.This paper briefly introduces advantages and effects of biological aerated fil⁃ter,analyzes in detail the community of microorganisms in biological aerated filter ( BAF) ,the site of inocula⁃tion and treatment of iron manganese, explores the influencing factors in the treating process ( effect of dis⁃solved oxygen,pH,Fe2+ to Mn2+,nutrients and coexisting ions),describes the optimum operating parameters and patterns of the filter,and points out the research direction and improvement of the biological filter in future.%在众多处理技术中，生物滤池由于具有运行成本低、操作简单、可以同步去除铁锰等物质的优势，被广泛运用于地下水除铁除锰工程中。介绍了生物滤池的优势与效果，详细分析了生物滤池中微生物的种类、接种和处理铁锰的部位，探寻了生物滤池处理过程中的影响因素：溶解氧、pH、Fe2＋对Mn2＋的影响、营养物质及共存离子，简述了生物滤池最适运行参数与方式。并在结论中指出了今后生物滤池需要改进的地方和研究方向。
