两级过滤去除地下水中铁锰的试验研究

Removal of iron and manganese from groundwater by two-stage filtration

通过锰砂和硅碳素两级过滤的方式,研究了含锰、含铁及高铁低锰三种水质条件下铁锰的去除效果,进一步探讨了不同水质中铁锰的去除方法。结果表明,对于单独含锰的水质,可仅采用二级硅碳素滤柱去除;对于单独含铁的水质,可仅采用一级锰砂滤柱去除;对于高铁低锰的水质,可通过两级过滤同时去除铁锰。锰砂和硅碳素两级过滤处理含铁锰地下水是可行的,根据不同的水质,可以采用不同的处理方法。

The effects of iron and manganese removal through the two-stage filtration of manganese sand and ANJ. SIC were investigated under the condition of three kinds of water quality, which were manganese alone, iron alone and higher iron with lower manganese. The methods of iron-manganese removal from different water qualities were further discussed. The result showed that it could be removed directly by ANJ. SIC filtration column for water containing manganese alone. It could be removed directly by one-stage manganese sand filtration column for water containing iron alone. It could be removed by two-stage filtration for water containing higher iron with lower manganese. It was feasible using a two- stage filtration to remove iron and manganese from groundwater by manganese sand and ANJ. SIC, and different methods could be done for different water qualities.
