超细骨碳除氟效果及影响因素的观察

目的:观察超细骨碳除氟效果及其影响因素。方法:比较三种吸附材料(竹碳、骨碳、活性碳)的超细颗粒对饮水中氟离子的吸附能力,pH值、聚合氯化铝对除氟效果的影响以及在自来水中的除氟效果。结果:骨碳与其他几种吸附材料相比具有较好的除氟效果,骨碳和混凝剂联合除氟效果比骨碳单独除氟效果要好,但达不到两者之和,在自来水中的除氟效果比在蒸馏水中要好且时间短。结论:骨碳超细粉有一定的除氟效果,但达到吸附饱和大约需9 0 min,与实际应用还有一定的距离。

A study on the effect of fluoride removal by the thin bone char and its influence factors

Objective: To observe the effect of the thin backbone grains to filter fluoride and the influence factors.Methods: Compare the different absorb abilities and filtration capabilities among the tiny grains of three adsorbing materials bamboocharcoal,backbone carbon,active carbon) for Fl ion in the drinking water as well as the influences of the effects to absorb and filter Fl ion by different factors such as pH value,coagulator and so on.Results: The filtration capability for F1 of bone coal is better than the others.It is more effective to filter fluoride by using combined coal bone and coagulator rather than solely using the coal bone,but not as good as using both methods.It is better and faster that the effect for filtering fluoride in the tap water rather than in the distilled water.Conclusion: The thin bone char grains have the effect of removing fluoride to some extent;however,it takes about 90 min to be adsorbent and saturated,which there still is a certain distance to the practical application.
