主 题:Progesterones Hospital wastewater Primary filtration treatment effluent Secondary biological treatment effluent Disinfection process
摘 要:Progesterones are ubiquitous in hospital wastewater(HWW)with concentrations much higher than those of estrogens and *** ensure that these water systems are safe to use,disinfection is crucial during HWW treatment by providingfront linedefense against biological ***,five disinfection processes,namely,chlorine(Cl_(2)),chlorine dioxide(ClO_(2)),ozone(O_(3)),ultraviolet(UV)),and UV/chlorine(UV/Cl_(2)),were selected to investigate their removal efficiencies for progesterones in primary filtration and secondary biological treatment *** were 61 natural and synthetic progesterones detected in HWW,with the natural progesterones being the main components with a concentration of 845.51 ng/L and contributing to 75.08%of the total *** primary filtration treatment presented insignificant removal effects on the progesterones,while the secondary biological treatment significantly reduced the progesterone content by *** order of removal efficiencies of total progesterones by different disinfection processes was UV/Cl_(2)Cl_(2)O_(3)ClO_(2)***/Cl_(2)showed the highest removal efficiency against progesterones mainly due to the activation of Cl_(2)by ultraviolet(UV)photolysis,which helps open the heterocyclic,aromatic,and phenolic rings,thus accelerating progesterone *** addition,the removal efficiencies of natural progesterones in the five disinfection processes were higher than those of synthetic progesterones(progesterone derivatives,19-nortestosterone derivatives,and 17α-hydroxyprogesterone derivatives).
