The invention provides a high-activity biological super strong water absorbing resin, the process for preparation comprises adding acrylic acid in a catalyst case according to quality portion, adjusting the pH value to 5-7, and adding a certain amount of maize starch, inorganic mineral substance, cross linker solution and initiating agent in turn, evenly stirring, warming up to 35 to 45 DEG C, polymerizing for 1.5-2 hours, stopping stirring when the system takes semitransparent gel shape, continuously warming up to 55-70 DEG C to polymerize 1-2 hours again till the system is turned to be gelatin, taking granulations out, drying, grinding to be half-finished product, and adding cross linker solution whose half-finished product quality is 0.01-1% and 0.01-1% high-activity biological agent, evenly stirring, placing in a drier, warming up to 60-100 DEG C to have a secondary treatment of surface cross bonding, and getting high-activity biological super strong water absorbing resin. The strong water absorbing resin product has the advantages of fast water absorbing speed, strong water absorbing capability, excellent anti adhesive properties after absorbing water, and which has the functions of resisting bacterium, absorbing osmyl, health care and the like, and can be applied in the production of women sanitary napkins, paper diaper, the aged health shorts and the like.
