Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a chemical sedimentation method for sedimenting negative ions in polluted water, and a continuous negative ion removing apparatus using the same. SOLUTION: In the method for removing negative ions from ground water, surface water, sewage or wastewater containing negative ions, a mixture of alumina cement and a calcium compound is added to water containing negative ions in a reaction tank equipped with a pair of electrodes and an electric field is applied to the interior of the reaction tank through the electrodes to form an insoluble complex salt. This insoluble complex salt is separated and removed from water containing negative ions.
