NOVELTY - Producing activated phosphate fertilizer using microbial inoculum and molasses ethanol waste liquid comprises filtering sugar factory molasses ethanol waste liquid, vacuum concentrating the liquid phase by a concentration device at a low temperature, spray drying the concentrate into dry powder, adding phosphate solubilizing bacteria, mixing and uniformly stirring to obtain mixture, adding the mixture into a normal phosphate fertilizer, mixing uniformly, drying, granulating in a granulator and drying to obtain granular activated phosphate fertilizer.    USE - The method is useful for producing activated phosphate fertilizer using microbial inoculum and molasses ethanol waste liquid (claimed).    ADVANTAGE - The method: prevents the investment problem in molasses ethanol production waste liquid processing cost; and reduces environmental pollution.    DETAILED DESCRIPTION - Producing activated phosphate fertilizer using microbial inoculum and molasses ethanol waste liquid comprises (a) filtering sugar factory molasses ethanol waste liquid via 5-15 meshes filter, where the waste liquid is carbonation or sulfitation process sugar molasses manufactured ethanol production waste mash, (b) vacuum concentrating the liquid phase by a concentration device at a low temperature, concentrating until the solid content is 30-50%, (c) spray drying the concentrate into dry powder, (d) adding 15-30% phosphate solubilizing bacteria (with active viable count of 200000000 cfu/g), mixing and uniformly stirring to obtain mixture of dry powder and phosphate solubilizing bacteria, (e) adding mixture of 10-20% dry powder and 80-90% phosphate solubilizing bacteria into a normal phosphate fertilizer and mixing uniformly, (f) drying the mixture at not greater than 60 degrees C until the water content is 12 plus minus 2% to obtain activated phosphate fertilizer powder and granulating in a granulator, and (g) granulating until the particle diameter is 1-4 mm, drying at not greater than 60 degrees C until the water content is less than 10% to obtain granular activated phosphate fertilizer.
