摘要
To predict the performance of UV systems for disinfecting wastewater a full scale UV system was subjected to changes in wastewater quality. The effect of changes in the UV transmission and suspended solids on fecal coliforms was measured. The level of UV transmission and suspended solids which can be treated is dependent upon the disinfection limit. There was no relationship between the UV transmission and the suspended solids and the degree of photoreactivation. An antibiotic labeled Escherichia coli was irradiated with the UV system and then observed in glass bottles and in the receiving stream for photoreactivation. Photoreactivation was observed in the glass bottles but not in the receiving stream. In the natural environment photoreactivation may not be important.
