Abstract—The modification methods on artificial existed in some degrees, such as high cost of
zeolite by NH4Cl-FeCl3 and NH4Cl-KAl(SO4)2 treatment, poor adaptability and applicability,
were studied by the experiment. The mechanism unstable efficiency of removing fluoride. To
on modifying adsorbent was preliminarily supply the safety drinking water to rural
discussed. The main technical parameters were residents, economical and applied treatment
determined on adsorption treatment of high technology of high-fluoride drinking water
fluoride drinking water using modified artificial should be urgently researched and developed
zeolite. The key factors of affecting the F- to meet the decentralized water supply in rural
removal efficiency were revealed. The study areas and small towns according to the
provided scientific basis for the development of characteristics of high-fluoride water.
efficient and practical small set for treating There are many advantages in adsorption
high-fluoride drinking water. Results show that treatment of high fluoride drinking water [6].
