The tested facility was a wastewater treatment plant (WWTP) in Swarzewo, where the wastewater treatment takes place in aeration chambers with activated sludge using sequential batch reactors (SBRs). The concentration of the following pharmaceuticals: ibuprofen, paracetamol, flurbiprofen, naproxen, diclofenac, and its metabolites 5OH-diclofenac and 4OH-diclofenac was tested in influents and effluents. Simultaneously, the conventional parameters were characterised. The removal of conventional pollutants was high (94.4-99.5%). At the same time, the removal of pharmaceuticals was variable. In the case of diclofenac and its metabolites, the concentration in the effluent was higher than in the influents. The risk quotients (RQs) calculated for analyzed pharmaceuticals suggest low environmental risk for selected species. However, negative impact for the biota due to the chronic presence of diclofenac cannot be excluded. It can be concluded that the SBRs, similarly to traditional flow activated sludge technology, are not efficient in the removal of target pharmaceuticals.
该试验设施是斯瓦泽沃的一家废水处理厂（WWTP），废水处理在曝气池和使用序批式反应器（SBR）的活性污泥中进行。对以下药物的浓度进行了测试：布洛芬、对乙酰氨基酚、氟比洛芬、萘普生、双氯芬酸及其代谢物 5OH-双氯芬酸和 4OH-双氯芬酸，在进水和出水。同时，对常规参数进行了特征描述。常规污染物的去除率很高（94.4-99.5%）。同时，药物的去除率是可变的。在双氯芬酸及其代谢物的情况下，出水中的浓度高于进水。对分析药物计算的风险商数（RQ）表明，所选物种的环境风险较低。然而，由于双氯芬酸的慢性存在，对生物群可能产生负面影响。可以得出结论，SBR 与传统的流动活性污泥技术一样，对目标药物的去除效率不高。
