The invention discloses spherical light kaolin ceramsite with an air purification function and through holes. The technical scheme mainly includes that ingredients for the spherical light kaolin ceramsite include attapulgite pottery clay powder with an air purification function, kaolin, activated argil waste residues, white carbon black, activated aluminum oxide, sodium aluminate, sodium dodecyl sulfate, kaolin photocatalyst spray liquid capable of being scrubbed and the like; the ingredients are subjected to stirring, extrusion granulation, drying, calcination, heat-insulation treatment, sieving, soaking, drying, sieving and hermetic packaging to obtain the spherical light kaolin ceramsite with the air purification function and the through holes. The spherical light kaolin ceramsite with the air purification function and the through holes has the advantages of large specific surface area, low stacking density, high moisture absorption, excellent adsorption performance, good lightweight strength and micropore and macropore integration. Besides, the spherical light kaolin ceramsite is suitable to be arranged in indoor environments, furniture and cupboards, vehicles, aircrafts, ships or other buildings, pollutants such as formaldehyde, ammonia, benzene and TVOC (total volatile organic compounds) can be adsorbed and degraded by the spherical light kaolin ceramsite, and accordingly the purpose of purifying air can be achieved.
