1. An ultraviolet disinfection apparatus comprising:
a hollow body comprising a cross-section and at least two open ends, each of the at least two open ends communicating with one end of a pipe structure, and further comprising an inner surface and an outer surface, the inner surface including one or more interior structures which is flat or curved, the one or more interior structures being defined by one or more partitions situated in part or in full length along the inner surface of the hollow space;
an ultraviolet (UV) module comprising one or more UV LED arrays independently or severally arranged with each other, the one or more UV LED arrays being mounted on the flat or curved surface of the interior structures; and
a control module being connected to the UV module and located remotely from the hollow body of the apparatus;
wherein the one or more interior structures is a partitioning element defined in a hollow space of the hollow body and extended from one end to another end of the inner surface of the hollow body to form at least one vertical or horizontal partition wall sub-dividing the hollow space of the hollow body into at least two relatively smaller hollow space, and wherein one or more surfaces of the partitioning element is mounted with one or more UV LED arrays.
