煤矸石除了大量用作燃料、建筑材料(如煤矸石多孔砖等)、生产工业原料(不同成分的煤矸石经处理后,可提取结晶铝、钛、硅等化工产品,有的还可生产电瓷元件、日用和工业陶瓷制品)之外,还可用以制取吸附剂。这是因为将煤矸石处理后能有效地吸附酚、氯酚、芳香烃等废水中的有机物,其吸附能力和吸附亲合力超过由高质量煤制备的传统的吸附剂——活性炭。
In addition to a large number of coal gangue used as fuel, building materials (such as coal gangue porous bricks, etc.), production of industrial raw materials (gangue with different components after treatment, can extract crystalline aluminum, titanium, silicon and other chemical products, and some can also produce electric porcelain In addition to components, household and industrial ceramic products, adsorbents can also be used. This is because the coal gangue can effectively adsorb organic substances in waste water such as phenol, chlorophenol, and aromatic hydrocarbons, and its adsorption capacity and affinity for adsorption exceed the conventional adsorbent made of high quality coal, activated carbon.
