| 摘 要： | 通过静态和动态(柱)吸附实验,探讨了活性Ti O2去除地下水中氟离子(F-)时活性Ti O2的投加量、处理时间、酸度等影响因素。实验结果表明:在静态实验中,在50mL,F-浓度为10mg/L的地下水样中,加入0.3g活性Ti O2,处理15min,F-的去除率可达90%以上,且处理前后水样的pH值不变。在动态实验中,0.3g的活性Ti O2和120g砾石可使150mL水样的除氟率达到90%以上。处理后均可达到饮用水的标准。

| Abstract: | Influences on removal of F~- contaminated groundwater by active TiO_2 were discussed depending on stationary and dynamic adsorption experiments. Parameters which are the amount of active TiO_2, resident time, and acidity etc. were considered. The experimental results indicated that in stationary experiments, 0.3 g active TiO_2 added to 50 mL 10 mg/L F~- contained groundwater, and with 15 min resident time, removal efficiency of F~- is more than 90%. Moreover, pH of the sample has not changed. In the dynamic experiments, 0.3 g active TiO_2 and 120 g gravel can treat 150 mL groundwater, and the removal efficiency of F~- is also more than 90%. Both of them are satisfied the drinking water standard. Therefore,the active TiO_2 can remove F~- in groundwater efficiently. |
