结合供水工程实例,研究和探讨了含铁含锰均较高的地下水的处理工艺。结果表明,采用一级接触过滤除铁、二级生物过滤除锰的两级过滤系统,不仅可避免铁对锰的去除的严重干扰,确保供水水质,而且还可能比采用一级接触过滤系统更节省投资。
Combined with water supply engineering examples, research and discussion on the treatment process of groundwater with high iron and manganese content are all included. The results showed that the two-stage filtration system using first-stage contact removal of iron and second-stage biological filtration of manganese not only avoided the serious interference of iron with manganese removal and ensured the quality of water supply, but also might be more than the first-stage contact filtration system Save investment.
