Geopolymer is an inorganic gel material with a three-dimensional network structure, which has a wide source of raw materials, simple preparation process, low energy consumption, and low pollution. It has the characteristics of excellent adsorption, high acid, and alkali corrosion resistance, and strong mechanical properties. Molecular sieve is an environmentally friendly adsorption materials with the advantages of uniform internal pore, large specific surface area, and high reaction selectivity. Molecular sieves can be formed from geopolymer under certain conditions due to the relationship of material transfer and structure inheritance with geopolymer. Industrial waste residue rich in silicon and aluminum elements can be used to prepare geopolymers and molecular sieves. Due to its own characteristics, molecular sieves are often used as adsorbent to treat industrial waste water, so as to realize the purpose of resource utilization and "waste treatment with waste". This work summarizes the geological polymer-based research progress of molecular sieve synthesis and application of industrial waste water, the introduction of molecular sieve raw material sources and material performance characteristic. The utilization of fly ash, tailings, slag geological polymer based material such as the preparation of molecular sieve synthesis method is summarized. The present situation of the application of molecular sieve material handling industrial waste water is analyzed. To explore more economical and advanced synthesis technology of molecular sieve and promote industrial application are prospected.
