| titleOfInvention | Preparation method of desulfurization and denitrification wastewater adsorbent |
| abstract | The invention belongs to the field of sewage treatment, and in particular relates to a preparation method of an adsorbent for desulfurization and denitrification wastewater. The preparation method of the desulfurization and denitrification wastewater adsorbent is to prepare hydrotalcite and polypyrrole-modified montmorillonite with adjustable interlayer structure respectively, and use the adjustable characteristics of the type and quantity of cations of the hydrotalcite plate to change the surface of the material. Electricity; by intercalating montmorillonite, the modification effect of montmorillonite polypyrrole is increased, and the adsorption properties of nitrate are improved at the same time as steric hindrance is formed; finally, the composite bond between hydrotalcite and montmorillonite is carried out. It can be intercalated to form a layered structure composite material with a certain steric hindrance. This material is used to adsorb nitrate in high-salt wastewater (especially high-salt wastewater with high sulfate content), and the adsorption selectivity and adsorption capacity are both It has good effect, and the removal rate of nitrate in wastewater is ≥60%. |
