摘要

Although ultraviolet (UA) irradiation and disinfection have been available since the early 1900s, engineers and others in the wastewater treatment industry did not embrace the idea until the mid-1980s. Today, uv installations are increasing dramatically. There are several reasons for this: (1) uv has proven its ability to disinfect pathogenic bacteria and viruses; (2) it is safer than hantoxic by-products formed during disinfection; and (4) the increasing cost of chlorination owing to regulations curbing discharge limits has encouraged uv use, as have stringent and costly regulations for storage and transport of chlorine gas, as part of the Uniform Fire Protection Code. Over the years, uv technology has become more reliable and predictable. Improvements in uv lamp technology have led to the introduction of medium-pressure uv sources for disinfection applications, expanding the range of water qualities that can be treated with uv radiation.
