Abstract
The invention discloses a preparation method and an application method of a silicon dioxide cluster-based novel settling agent. Silicon dioxide clusters serve as settling agent main bodies, and metalions and the silicon dioxide clusters are combined by utilizing the strong interaction between the silicon dioxide clusters and the metal ions, so that a metal ion modified settling agent is obtained,and the content of metal ion residues such as aluminum ions in the treated water body can be reduced; the settling agent provided by the invention can be selectively combined with blue-green algae, so the influence on other aquatic organisms is greatly reduced; the density of the final settling material can be adjusted by adjusting the polymerization degree or grain size of the silicon dioxide clusters in the settling agent and the metal content, the prepared settling material can float on the water surface and also can sink into the water bottom, and different salvage treatment requirementscan be met; and the settling agent provided by the invention is faintly acidic, so the living environment of the blue-green algae can be broken by a mode of reducing the pH value of the water body while the blue-green algae are settled, and the growth of the blue-green algae can be inhibited.
