Zusammenfassung:	The invention discloses a metal modified SAPO-34 molecular sieve, and a preparation method and application thereof. The preparation method comprises adding a tungsten source and an SAPO-34 molecular sieve into a solvent, performing ultrasonic and microwave treatment, drying and roasting to obtain the tungsten modified SAPO-34 molecular sieve, wherein the tungsten source is a soluble tungsten source or an insoluble tungsten source; or mixing an aluminum source, a phosphorus source and deionized water into liquid A, mixing a main template agent and a silicon source into liquid B, mixing the liquid A and the liquid B, adding a tungsten source template agent, performing dynamic crystallization, drying and roasting to obtain the tungsten modified SAPO-34 molecular sieve; or mixing an aluminum source, a phosphorus source and deionized water into liquid A, mixing a main template agent and a silicon source into liquid B, adding the liquid B into the liquid A, performing dynamic crystallization, adding a tungsten sour
