摘要
A waste water treatment equipment treats a fluorine waste water containing organic matter, nitrogen, phosphor and hydrogen peroxide by an anaerobic tank 3 in which a calcium carbonate mineral 9 is placed and an aerobic tank 15 in which the calcium carbonate mineral 9 is placed and into which a biologically treated water is introduced from a treatment equipment 444 of another system. Therefore, the fluorine in the waste water can be treated by the calcium carbonate mineral 9 placed in the anaerobic tank 3 and the aerobic tank 15 with the formation of calcium fluoride 11. The organic matter of the surface active agent and so on in the waste water can be treated by the microorganism included in the biologically treated water. Furthermore, nitrate nitrogen can be treated so as to be reduced to a nitrogen gas in the anaerobic tank 3, while ammoniacal nitrogen and nitrite nitrogen can be treated so as to be oxidized in the aerobic tank 15. That is, the waste water treatment equipment can highly efficiently treat the surface active agent, nitrogen, polychlorinated aluminum, macromolecular coagulant, hydrogen peroxide and phosphor in the waste water, by which the waste can be reduced.
