The honeycomb type nano zinc oxide purifying activated carbon is prepared from raw materials of, by weight, 17-28 parts of chemical activated carbon, 15-25 parts of coaly granular activated carbon, 50-60 parts of coconut shell activated carbon, 4-6 parts of nano zinc oxide 99% in purity, 1-2 parts of methylcellulose and 1-2 parts of talc powder. The method includes the steps of performing ball milling, raw material mixing and uniform stirring to prepare product materials, and then preparing the honeycomb type nano zinc oxide purifying activated carbon via vacuum pugging, extrusion forming, airing and sintering. By the method, the activated carbon can have an excellent contaminant absorption function, can decompose poisonous gases such as formaldehyde, ammonia and benzene absorbed therein under the action of ordinary light, in other words, has a self-purifying function, and further has the advantages of being formable, firm, durable in use, simple and feasible in method, low in pollution treatment cost, low-carbon, energy saving and good in treatment effect.
