The invention discloses an industrial preparation method of a zirconium loaded nanocomposite resin adsorbent, belongs to the fields of industrial production of nanocomposite resin adsorbents for wastewater treatment and particularly relates to the industrial preparation method of the zirconium loaded nanocomposite resin adsorbent recycled and reused with reaction mass. The industrial preparation method includes the steps: A), preparing a zirconium salt solution; B), adding strongly-basic anion resin to the zirconium salt solution in batches prior to stirring and soaking, wherein the zirconium salt solution is recycled and reused; C), performing drying; D), performing alkalization by adding a sodium hydroxide solution to obtain zirconium loaded nanocomposite resin, wherein alkaline liquor is recycled and reused; E), adding a hydrochloric acid solution for neutralization; F), performing washing. With the method, all the materials of cleaning fluid, the zirconium salt solution, the alkaline liquor, acid liquor, ethyl alcohol and the like can be recycled and reused, production cost and environment pollution are greatly reduced, energy conservation and emission reduction industrial policy of the current state is conformed, and the method is suitable for industrialized promotion.
