粉末炭-超滤工艺出水氯和氯胺消毒安全性评价
Safety evaluation of chlorine and chloramine disinfection with treated water of PAC-UF treatment process
摘要
Abstract
Pollutants removal effects of powdered activated carbon-ultrafiltration（PAC-UF） treatment process was examined.Disinfection effect of chlorine and chloramines were compared on control of microbe regrowth and disinfection by-products formation.The safety of treated water of the PAC-UF treatment process was comprehensively evaluated.The results show that colloids and pathogenic microbes can be removed efficiently by the PAC-UF treatment process.Average removal rates of ammonium,CODMn（chemical oxygen demand）,UV254（ultraviolet in 254 nm） and DOC（disolved organic carbon） are 36.04%,44.28%,44.94% and 30.65% respectively.The bacteria and coliform index of the water samples appears significantly regrowth after 24 h without disinfection.Chloramine has better continuous disinfection effects than chlorine′s effects on inactivation of microbe and maintenance of residual chlorine.The THMs（trihalomethanes） and HAAs（haloacetic acids） produced by chloramine disinfection are lowered 63.42% and 44.13% than by chlorine disinfection respectively,and formation of brominated disinfection by-products is decreased effectively too.Safeties of treated water by PAC-UF treatment process can be enhanced by chloramines.关键词
