The invention relates to ceramic filtration materials, in particular to a purifying and extruding attapulgite ceramisite filter material. A method for preparing the extruding ceramisite filter material by performing wet purification on attapulgite clay lies in that after purification, attapulgite clay is stirred, uniformly blended, kneaded, extruded for shaping, and is further dried and roasted to obtain the finished product. The purifying and extruding attapulgite ceramisite filter material provided by the invention can efficiently adsorb and purify pollutants in the water, and can also be used for efficiently removing harmful gases such as NOx, VOCs, NH3, H2S and SO2, and the advantages of high mechanical strength, small air resistance, high air porosity, large specific surface area, high adsorption capacity, good stability, low cost, reusability and reproducibility can be achieved.
