description The invention discloses a method for preparing a zeolitic particulate material from washed coal gangue. The method comprises the following steps: crushing and sieving the ash residue obtained after the washed coal gangue is calcinated at a temperature of 650 to 900 DEG C, and adding the obtained particulate matter to a sodium hydroxide solution, so that an active silicon aluminum component in theparticulate matter is reacted with sodium hydroxide to crystallize and grow zeolite 4A on the surface of the particulate matter, namely, the zeolitic particulate material. The zeolitic granular material prepared from the washed coal gangue disclosed by the invention has the advantages of wide source of raw materials, comprehensive utilization of waste, and low preparation cost, the synthetic zeolite is mainly distributed on the surface of the particulate matter, the speed of adsorbing a pollutant is fast, and the zeolitic particulate material can be widely applied to a percolation material forpolluted rainwater treatm
