Problems solved by technology

Utilizing the characteristics of large pore size, high porosity and stable structure of zeolite, using zeolite as the carrier, combined with the advantages of large adsorption capacity and high adsorption efficiency of the three-dimensional network structure of airgel, it overcomes the easy collapse of the airgel structure and small pore size. Disadvantages: The preparation of sewage treatment materials with large adsorption capacity, good adsorption efficiency, and stable structure is suitable for sewage treatment technology, but its adsorption performance for pollution factors and heavy metal elements in water bodies is weak, which cannot meet the needs of actual use.
