摘要
根据铁细菌的生物除锰作用 ,提出了“简单曝气 +一级生物过滤”的地下水生物处理工艺 ,实现了高含量铁锰同时去除的效果 ,促进了滤层稳固除锰能力的形成 ;同时 ,对提出的生物工艺的运行影响因素进行了分析。试验结果表明 ,地下水除铁除锰生物工艺具有经济、高效的曝气、过滤单元。
A process of simple aeration + primary biological treatment based on the Mn removal capacity of ferro bacteria has been proposed. It can remove both Fe and Mn simultaneously from underground water with high Mn and Fe content and can enhance the formation of the stable Mn removal ability of the filtration layer. The influence factors to the concerned process are discussed. The experiment results has shown that this is an economical filtrating unit operation with high aeration efficiency to remove Fe and Mn.
