    摘要: The present disclosure relates to a method for removing anions such as nitrate ion, sulfate ion, chloride ion, and phosphate ion existing in underground water, surface water or waste water. The method involves adding alumina cement and a calcium compound to the water containing the anion followed by applying an electric field thereto, thereby forming a chemical precipitate which is an insoluble complex salt. The disclosure also relates to a continuous process for removing the anion by continuously performing the above method for removing anions.
