摘要： 地质聚合物是三维立体网状结构的无机凝胶材料，其具有原料来源广泛、制备工艺简单、耗能小、污染低，其具有优良的吸附性、较高耐酸碱腐蚀性和较强机械性能等特点。分子筛具有内部孔道均匀、比表面积大、反应选择性高等优点，是一种新型环保的吸附材料。由于其与地质聚合物存在物质传递和结构遗传的关系，分子筛可在一定条件下由地质聚合物转化而成。富含硅铝元素的工业废渣均可制备地质聚合物和分子筛，由于其自身特点，常被用作吸附剂处理工业废水，从而实现资源化利用和“以废治废”的目的。本工作综述了地质聚合物基分子筛合成和工业废水应用方面的研究进展，介绍分子筛原料来源和材料性能特点，总结利用粉煤灰、尾矿、矿渣等材料制备地质聚合物基分子筛的合成方法，分析分子筛材料处理工业废水的应用现状，对寻找到更加经济先进的分子筛合成工艺和推广工业化应用进行展望。

Abstract: 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.
