一家臭氧和紫外线消毒中试工厂接收了德国城市污水处理厂(STP)的出水，以测试从城市污水中去除药物、碘化X射线造影剂(ICM)和麝香香料的情况。在原污水处理厂出水中，5种抗生素(0.344.63杯L(-1))、5种抗炎药物(0.18-1.7杯L(-1))、4种抗炎药物(0.1-1.3杯L(-1))、2种调脂代谢产物(0.12-0.13杯L(-1))、抗癫痫药物卡马西平(2.1杯L(-1))、4种ICM(1.1-5.2杯L(-1))，用LC-电喷雾串联质谱仪和/或GC/MS/MS联用技术检测到天然雌激素雌酮(L 0.015-1)和麝香香料2种(L 0.14.73-1)，经放射学检查，ICM的浓度最高(泛影葡胺5.7 g L(-1)，碘普罗胺5.2 g L(-1))。用10-15 mg L(-1)臭氧作用18min，所有受试药品及麝香香料(六六六、六六六、三羟甲苯)和雌酮均检不出。然而，ICM(泛影葡胺、碘帕咪醇、碘普罗胺和碘丙醇)仍在相当大的浓度下被检测到。即使在臭氧投加量为15 mg L(-1)的情况下，离子型泛影葡胺的去除效率也不超过14%，而非离子型离子交换膜的去除效率可达80%以上。高级氧化工艺(O-3/UV-低压汞弧，O-3/H_2O_2)没有优化用于废水处理，与单独使用臭氧相比，ICM的去除效率并没有显著提高。(C)2002爱思唯尔科学有限公司。保留所有权利。
A pilot plant for ozonation and UV-disinfection received effluent from a German municipal sewage treatment plant (STP) to test the removal of pharmaceuticals, iodinated X-ray contrast media (ICM) and musk fragrances from municipal wastewater. In the original STP effluent, 5 antibiotics (0.344.63 mug l(-1)), 5 betablockers (0.18-1.7 mug l(-1)), 4 antiphlogistics (0.10-1.3 mug l(-1)), 2 lipid regulator metabolites (0.12-0.13 mug l(-1)), the antiepileptic drug carbamazepine (2.1 mug l(-1)), 4 ICM (1.1-5.2 mug l(-1)), the natural estrogen estrone (0.015 mug l(-1)) and 2 musk fragrances (0.14.73 mug l(-1)) were detected by LC-electrospray tandem MS and/or GC/MS/MS. ICM, derived from radiological examinations, were present with the highest concentrations (diatrizoate: 5.7 mug l(-1), iopromide: 5.2 mug l(-1)). By applying 10-15 mg l(-1) ozone (contact time: 18 min), all the pharmaceuticals investigated as well as musk fragrances (HHCB, AHTN) and estrone were no longer detected. However, ICM (diatrizoate, iopamidol, iopromide and iomeprol) were still detected in appreciable concentrations. Even with a 15 mg l(-1) ozone dose, the ionic diatrizoate only exhibited removal efficiencies of not higher than 14%, while the non-ionic ICM were removed to a degree of higher than 80%. Advanced oxidation processes (O-3/UV-low pressure mercury arc, O-3/H2O2), which were non-optimized for wastewater treatment, did not lead significantly to a higher removal efficiency for the ICM than ozone alone.
