Abstract: The invention provides an inorganic electrolyte setting agent capable of blocking hazardous heavy metals almost permanently and further usable as resources, based on the geological balance of elements, and a treating method for utilization as resources using the same. There is provided an inorganic electrolyte setting agent capable of rendering heavy metal ions nonhazardous, including an aqueous solution as a main agent mixed with A below and also at least one of B and C below: (A) sulfuric acid, (B) at least one of aluminum sulfate and polyaluminum sulfate, (C) at least one of polyferric sulfate and ferric chloride; and an aqueous solution as a concomitant agent mixed with D below: (D) at least one of potassium silicate and sodium silicate.

Abstract: A method of treating and activating sea water or polluted water into drinking water comprising the steps of separating and removing impurities from sea water or polluted water containing a great amount of deleterious materials such as chlorine, various kinds of heavy metals, environmental hormones, and miscellaneous bacteria by an electrode located in a primary treating tank, then introducing sea water or polluted water subjected to the primary treatment into a filtration tank for filtration and further introducing filtered water into a secondary treating tank, releasing useful minerals by magnetic ores and providing active power to various kinds of useful organic materials remained not filtered in the treated water.

Abstract: Contaminated sediments in such bodies of water as lakes and ponds, inner bays and rivers obtained by dredging are converted into favorable soils by adding to the contaminated sediments and aqueous solution formed by mixing an inorganic electrolytic coagulant obtained by mixing phosphonic acid and magnesium sulfate in a solvent not containing chlorine, stirring them for several minutes and then mixing aluminum sulfate and polyferric sulfate and stirring them for several minutes, together with a soil particle reinforcing agent and a pH controller.
