Beschreibung
Zusammenfassung:	The invention discloses a blue-green algae scavenger and a preparation method thereof, and relates to the field of water pollution control. According to the preparation method, polyacrylonitrile is taken as a core layer, tetrabutyl titanate and polyvinylpyrrolidone are taken as a shell layer, coaxial electrostatic spinning is performed to prepare a fiber membrane, and then first high-temperature treatment and second high-temperature treatment are performed to prepare the modified silicon dioxide fiber membrane. The quantity of blue-green algae is reduced by utilizing the photooxidation effect of titanium dioxide and the adsorption effect of a fiber net structure, so that the blue-green algae scavenger has a blue-green algae removal effect; then, the modified titanium dioxide fiber membrane sequentially reacts with N, N-diethyl-3-(trimethoxysilyl) propylamine and 1, 4-butane sultone to form a mesoporous silica coating layer with a quaternary amine structure and a sulfonic acid group, so that the adsorption and
