1. A method for synthesizing a supported type-A molecular sieve membrane by microwaves, comprising the steps of aging, heating and synthesizing, wherein:
the step of aging comprises contacting a support with a synthetic liquid at an aging temperature 25° C. to 50° C. for 16 hours to 20 hours to obtain an aged system;
the step of heating comprises raising a temperature of the aged system from the aging temperature to a synthesis temperature within 3 minutes to 6 minutes under microwave heating;
the step of synthesizing comprising synthesizing the aged system at the synthesis temperature of 80° C. to 120° C. for 6 minutes to 10 minutes under microwave heating, and
the synthetic liquid contains 2.64 mol/L of Na2O, 0.053 mol/L of Al2O3, and 0.263 mol/L of SiO2.
