Abstract: The present disclosure discloses a method for water purification through fresh generation of a flocculant, including the following steps: (1) mixing a water-purifying agent precursor with a liquid, exciting a resulting mixture, and adding an excited mixture to water to be purified; and/or mixing the water-purifying agent precursor directly with the water to be purified, and exciting a resulting mixture, so that the water-purifying agent precursor undergoes a reaction to produce ferric hydroxide and the ferric hydroxide co-settles with suspended matters and/or impurities in the water to be purified, where the exciting includes addition of an oxidizing substance; and (2) subjecting a mixture obtained in step (1) to SLS to obtain purified water. This method can effectively settle suspended matters in water and adsorb some organic impurities without producing acids and salts during fresh generation of hydroxides, ensuring water-drinking health and reducing the adverse effects of recycling of industrial water.
