The Research on the Fuxin Zeolite Used in Eliminate the Fluorine Waste Water and It's Mechanism

摘要

Fu Xin City is located in Liaoning province western part, belongs to arid area, is lack of water resources, is the productive base of synthesizing fluorine medicine and the fluorine pesticide in china. Hydrogen fluoride is used in those production, thus large amount of hydrogen fluoride and floration are contained in waste liquid after compsing. The fluorine ion is 80.S4mg/L in the water by processing, but the country stipulates that fluorine ion is less than 10 mg/L, so the XiHe water of FuXin is polluted and harmful to resident. The key point of this article is to explore reasonable method and the craft of eliminating the fluorine. The zeolite is chosen as fluorine medicinal preparation and its mechanism is researched after comparison of carrying on three kinds of fluorine medicinal preparation: the zeolite, the animal charcoal, the activated alumina. Carrying on the analysis after the Fuxin natural zeolite physical property, many kinds of activation plan have been chosen, and the zeolite particle has been determined through data analysis which obtains after the experiment The dynamic experiment and the static experiment are combined in the research of eliminating fluorine performance of zeolite and the zeolite activation and the regeneration condition have been explored, the influence factors and extent of zeolite eliminating the fluorine have been define, the adsorption isothermal and the adsorption speed of the zeolite eliminating the fluorine have been studied.
