| 摘 要： | 氟元素与人体健康关系比较密切，其含量过高和过低对人体健康都有危害，因而对地下水中氟污染物的研究，意义重大。为此人工配制了含F-为1．00～3．00mg／L、不同Mn2＋、Fe2＋浓度的原水，并通过已经培养成熟的生物除锰除铁滤池进行过滤。结果表明，进水pH（5．5～7．5）为中性条件下，滤池对氟具有长期稳定的微弱去除效果。在低pH（2．5—3．5）条件下，出水F-浓度在短时间内达到生活饮用水标准。

| Abstract: | The fluorine element and human health have quite close relations. Too high or low content of fluorine are harmful to human health, thus the research on fluorine pollution in groundwater is of great significance. Water samples with fluorine con- centration of 1.00 ~ 3.00 mg/L were prepared with different Mn2＋ and Fe2 ＋concentrations, and then filtrated by the fostered bio - filter. Results show that at the filter has weak and long - term removing effects under neutral pH（5.5 - 7.5 ） conditions. At low pH （2. 5 - 3.5 ） conditions, the fluorine concentration in the filtrated water reach the drinking water standard within short period.
