The invention provides a burn-free 
coal-ash-based geological 
polymer high performance adsorbing material preparation method which comprises the following steps: a, preprocessing a 
solid raw material; b, preparing a base material, wherein 
solid waste 
coal ash containing rich 
aluminosilicate is utilized as the 
solid raw material, an alkali activator is utilized as a liquid 
raw material, and the solid raw material and the liquid raw material are evenly mixed to react at a temperature of 20 to 100 DEG C to form a base; c, forming a base material, i.e., forming the evenly-mixed solid and liquid raw materials into a base sample through 
granulation molding or 
casting molding or 
extrusion molding; d, maintaining the base sample; e, washing and 
drying. The method can save energy, is simple in preparation technology, can reduce production cost, can be used to produce a high performance geological 
polymer adsorbing material in a large scale, and the waste 
coal ash of coal-fired power plants is utilized as a raw material to prepare the adsorbing material at a 
room temperature; thus, the problem of coal ash stack and waste and the environmental problems caused by the coal ash stack and waste are solved, and industrial organic 
waste gas and waste water containing 
phenol can be treated in a mode of using waste to treat waste.
