Abstract:

Based on stationing monitoring and sampling analysis for a Xi’an sewage treatment works operating with A2/O process and medium loading process, the distribution and transformation regularity of pharmaceutical pollutants were studied.The results showed that there were six typical pharmaceuticals, Phenacetin, Gemfibrozil, Caffeine, Aminopyrine, Clofibrate acid and Diclofenac acids in flooding water at the concentrations of 14.98 μg·L^-1, 0.64 μg·L^-1, 19.36 μg·L^-1, 2.15 μg·L^-1, 0.95 μg对西安市某污水处理厂A2/O工艺和中负荷工艺布点监测，以分析医药类污染物的分布与迁移转化规律。检测分析表明，污水厂进水中含有非那西丁、吉非罗齐、咖啡因、氨基比林、降固醇酸和双氯芬酸等6种医药类污染物，其浓度分别为14.98 μg·L^-1、0.64 μg·L^-1、19.36 μg·L^-1
