Adsorptive filler for river water purification and preparation method thereof

Abstract

The present disclosure discloses an adsorptive filler for river water purification and a preparation method thereof, comprising: S1, preparing a composite zeolite powder; S2, preparing a vinyl-functionalized composite zeolite powder; S3, preparing an organically modified composite zeolite powder; S4, preparing a modified composite zeolite powder; and S5, uniformly mixing the modified composite zeolite powder, fly ash, biochar and medical stone to obtain a dry powder, then adding a sodium alginate solution and stirring to obtain a pasty slurry, subsequently dropping the pasty slurry into a calcium chloride solution, soaking and aging, and then filtering, washing and drying to obtain the product. In the adsorptive filler, the modified zeolite powder is uniformly co-mixed with fly ash, biochar and medical stone, and all powder components are solidified and shaped by means of sodium alginate.
