The utility model provides a kind of vegetables and fruits sterilizing decontaminating apparatus, and it includes set water container, water level sensing mould group, ozone mould group, ultraviolet light mould group and control mould group. Set the retaining wall that water container includes bottom wall and upwardly extended by bottom wall. Water level sensing mould group includes the first sensor and what retaining wall is arranged in the second sensor, and provides the first water level signal and the second water level signal, the vertical range of the vertical range of the first sensor and bottom wall high what the second sensor and bottom wall. Ozone mould group provides ozone to setting in water container, and ultraviolet light mould group offer ultraviolet lighting, which is mapped to, sets water container. It controls mould group and receives the first water level signal and the second water level signal, ozone mould group and ultraviolet light mould group is respectively started according to the first water level signal and the second water level signal. Thereby, it can control ozone amount and promote sterilizing and clean ability.本新型提供一種蔬果滅菌洗淨裝置，其包含置水容器，水位感測模組，臭氧模組，紫外線模組及控制模組。置水容器包含底壁及由底壁向上延伸之擋壁。水位感測模組包含第一感測器及第二感測器設置於擋壁，且提供第一水位訊號及第二水位訊號，第一感測器與底壁的垂直距離高於第二感測器與底壁的垂直距離。臭氧模組提供臭氧到置水容器內，紫外線模組提供紫外光照射到置水容器。控制模組接收第一水位訊號與第二水位訊號，依第一水位訊號與第二水位訊號分別啟動臭氧模組與紫外線模組。藉此，可以控制臭氧量並提升滅菌洗淨能力。
