<p>PURPOSE:To obtain a titled drug which can quickly clean up sewage without requiring sewage treatment facilities by kneading calcined plaster and granular magnetic material with hydrogen peroxide water, then solidifying and molding the mixture. CONSTITUTION:The calcined plaster and granular magnetic material (e.g., magnetic iron ore particles) is kneaded with the hydrogen peroxide water and the mixture is solidified and molded. The resulted drug is sprayed onto a water surface, by which the increase of dissolved oxygen, the acceleration of a biochemical reaction, the acceleration of a settling effect and the synergistic effect thereof are induced. The quick cleaning up of the sewage is thus made possible without requiring the sewage treatment facilities. This drug is particularly effective for cleaning up the sewage of a vast water surface in lakes, swamps, etc.</p> |
