| titleOfInvention | A kind of nitrogen-removing water purifying agent and preparation method thereof |
| abstract | The invention discloses a preparation method of a nitrogen-removing water purifying agent, comprising the following steps: preparing a titanium-containing wet gel; mixing the prepared titanium-containing wet gel, plant straw powder, fly ash, clay, zeolite powder, Deionized water is mixed and granulated, and sintered to obtain mesoporous composite ceramsite; 3-aminopropyltriethoxysilane is grafted on the surface of the above-mentioned mesoporous composite ceramsite to obtain modified mesoporous composite ceramsite; graphite oxide is prepared Graphene dispersion liquid and mesoporous composite ceramsite dispersion liquid, drop the mesoporous composite ceramsite dispersion into the graphene oxide dispersion liquid, stir after the dropping, add aqueous ammonia solution and hydrazine hydrate dropwise, stir and process, and then transfer to The reaction is carried out in the autoclave, and after the reaction is completed, it is cooled to room temperature for aging treatment to obtain a nitrogen-removing water purifying agent. The nitrogen-removing water-purifying agent prepared by the invention has large specific surface area, strong adsorption force, certain photocatalytic activity and certain ion exchange capacity, can effectively remove ammonia nitrogen and nitrate nitrogen in wastewater, and has no effect on water body. Secondary pollution. |
