Abstract |
Since significant amounts of pharmaceuticals are discharged into sewer systems daily, their impacts on the biological process of a wastewater treatment system are becoming a cause of increasing public concern. In this study, therefore, two lab-scale activated sludge systems were constructed, and the impacts of influent pharmaceuticals on their performances were investigated. More specifically, one system was step-fed with 1 mg/ L acetaminophen and the other with 1 mg/L sulfamethoxazole. In the former case, the activated sludge system was slightly affected by the chemical in the initial phase. In the latter case, the system was severely affected, with effluent DOC and sulfamethoxazole concentrations exceeding over 40 and 800 mg/L, respectively. Nonetheless, both systems could degrade the pharmaceutical compounds when they were exposed for longer than 100 h. |
