The invention relates to a preparation method of a 3D printing geopolymer adsorbent. The problems that an existing powder geopolymer is prone to agglomeration and difficult to recycle, and a block geopolymer is poor in adsorption efficiency are solved. The preparation method of the 3D printing geopolymer adsorbent comprises the following steps: (1) preparing ink; (2) performing 3D printing forming; and (3) drying and curing a green body. The geopolymer adsorbents with different 3D configurations are formed by adopting a direct writing type 3D printing technology, and direct interface contact between the adsorbents and sewage can be effectively increased, so that the mass transfer path of pollutants is shortened, and the adsorption efficiency is improved.
本发明涉及一种3D打印地质聚合物吸附剂的制备方法，消除了现有粉体地质聚合物易团聚、难回收及块体地质聚合物吸附效率不佳的难题。本发明的3D打印地质聚合物吸附剂的制备步骤有：（1）墨水配制；（2）3D打印成型；（3）坯体干燥和养护。本发明采用直写式3D打印技术成型不同3D构型的地质聚合物吸附剂，可有效增加吸附剂与污水直接的界面接触，从而缩短污染物的传质路径，提高吸附效率。
