The present invention discloses a toilet sterilization system comprising a toilet body, a driving module, at least one trigger module and a processing module. The toilet body includes a toilet cover, and a plurality of ultraviolet light-emitting units are disposed on one side of the toilet cover, and the plurality of ultraviolet light-emitting units are turned on according to a first control signal or closed according to the second control signal. The driving module is disposed on the toilet body and connected to the toilet cover, and covers the toilet lid according to the first control signal or opens the toilet lid according to the second control signal. The at least one trigger module senses the inactive state to generate the first trigger signal and the inductive use state to generate the second trigger signal. The processing module is disposed on the toilet body and is connected to the plurality of ultraviolet light emitting units, the driving module and the at least one triggering module. The processing module receives the first trigger signal and transmits the first control signal to the plurality of ultraviolet light emitting units and the driving module. Or receiving the second trigger signal and transmitting the second control signal to the plurality of ultraviolet light emitting units and the driving module.本創作係揭露一種馬桶殺菌系統，係包含馬桶本體、驅動模組、至少一觸發模組及處理模組。馬桶本體包含馬桶蓋，馬桶蓋之一面設有複數個紫外線發光單元，複數個紫外線發光單元依據一第一控制訊號開啟或依據第二控制訊號關閉。驅動模組設於馬桶本體上且連結馬桶蓋，並依據第一控制訊號蓋上馬桶蓋或依據第二控制訊號開啟馬桶蓋。至少一觸發模組感應停用狀態產生第一觸發訊號及感應使用狀態產生第二觸發訊號。處理模組設於馬桶本體上且連結複數個紫外線發光單元、驅動模組及至少一觸發模組，處理模組接收第一觸發訊號並傳送第一控制訊號至複數個紫外線發光單元及驅動模組，或接收第二觸發訊號並傳送第二控制訊號至複數個紫外線發光單元及驅動模組。
