【Abstract】 This thesis introduces the method to look for new water source in terms of hydrological geology and natural conditions. By comparing various defluorine methods both at home and abroad, three kinds are summarized: coagulation precipitation, the filter bed adsorption, and the electrification defluorine, altogether some 20 methods. Analysis and comparison are done in defluorine methods, the principles, change of disposed water quality, consequence of water treatment and its cost, the advantages and disadvantages, adaptability and so on, and several applicable methods are introduced.更多还原
