The invention discloses a process for preparing a sodium-containing bentonite additive. After mixing the photocatalyst and the high-temperature anti-explosion agent, add it to the slurry obtained in step (1), at room temperature, and stir for 5-8 hours; (3) add 30% acrylamide aqueous solution to the product obtained in step (2), and continue to stir and mix Then, add 3% NN-methylbisacrylamide, ion exchange resin, oxidizing agent and reducing agent. After fully stirring and mixing, carry out the polymerization reaction at room temperature. A gelatinous polymer is obtained, which is dried and pulverized to prepare a sodium-containing bentonite additive. The invention improves the adsorption capacity of the sodium bentonite, thereby increasing the antifouling and wastewater treatment effects. |
