摘要： A high percentage of fluorine in fluorine-containing water is removed and high purity calcium fluoride is recovered when treating the fluorine-containing water by passing the same through calcium carbonate packed towers provided in series in a plurality of stages, preferably two stages. In a method including passing fluorine-containing water through calcium carbonate packed towers provided in series in a plurality of stages to remove the fluorine in the fluorine-containing water and recover calcium fluoride, the calcium carbonate towers are packed with calcium carbonate with a volume mean diameter of 30 to 150 μm. By the use of calcium carbonate granules with a volume mean diameter of 30 to 150 μm, an increase in the purity of the recovered calcium fluoride and an increase in the fluorine removal ratio can be realized with a relatively small device.

摘要： The present invention provides a novel adsorbent carbon supported activated alumina (CSAA) which posses both the advantageous characteristics of carbon and alumina viz., the high specific surface area associated with activated carbon and high sorption capacity of alumina towards F− Carbon supported activated alumina has an added advantage of its usage in the neutral pH unlike alumina and alumina impregnated carbon which are found to be efficient only in acidic pH. It is more efficient compared to carbon in terms of its sorption capacity towards F− and is therefore useful for the efficient removal of fluoride ions from water.

摘要： Drainage water containing an organofluorine compound is introduced into a raw tank (1) and then filtered through a filtration device (4). Next, a microorganism, a micro-nanobubbling auxiliary agent and a nutrient are added thereto in a first transit tank (5) while micro-nanobubbles are generated thereinto by a micro-nanobubbling machine (7), thereby giving treated water. This treated water is then fed into an active carbon column (14) and then the above-described organofluorine compound contained in the treated water is decomposed by the microorganism as described above.

摘要： The invention provides a method for recovery of a fluorinated anionic surfactant from a basic anion exchange resin having quaternary ammonium groups, the method comprising eluting the anion exchange resin with a composition comprising an ammonium salt and a water miscible organic solvent. The method according to the invention may provide one or more of the following advantages. For example, the method can be designed to allow for recovery of substantially all of the fluorinated surfactant from a basic anion exchange resin having quaternary ammonium groups. Also, the liquid used for recovering the surfactant from the anion exchange resin is a simple liquid that can be readily and cost effectively manufactured. Further the process may be carried out in a convenient and easy manner. Furthermore, the method generally does not require large amounts of the eluting composition.

摘要： An adsorption process in which high adsorption of C2-C6 fluorine-containing compound can be attained without any morphological change thereof by the use of active carbon; and a desorption process in which active carbon and adsorbed substances can be recycled by desorption from active carbon. A liquid containing the C2-C6 fluorine-containing compound is brought into contact with active carbon to thereby cause the active carbon to adsorb the fluorine-containing compound and thus obtain a liquid of low fluorine-containing compound content. The active carbon having the adsorbed fluorine-containing compound is heated so as to desorb the fluorine-containing compound from the active carbon.
