Sewage treatment plant (STP) effluents are significant sources of pharmaceutical residues in surface waters, where high concentrations of the antiepileptic drug Carbamazepine have been detected. The solids retention time (SRT) is the most important parameter for the design of STPs. It relates to the growth rate of microorganisms and to effluent concentrations. The influence of SRT on the removal of Carbamazepine was studied on lab-scale plants. The results from these tests were then validated on several full-scale plants. Due to the lack of suitable receiving waters and groundwater resources, one of these STPs has to infiltrate the treated wastewater into unsaturated soil. Here, groundwater samples at equal distances from the infiltration point were taken to estimate the behaviour of Carbamazepine during soil passage and within the groundwater. This antiepileptic drug seems to be very persistent in the environment, therefore qualifying as a suitable marker for anthropogenic influences in the aquatic environment.
污水处理厂（STP）的废水是地表水中药物残留的重要来源，在这些地表水中已检测到高浓度的抗癫痫药物卡马西平。固体停留时间（SRT）是污水处理厂设计中最重要的参数。它与微生物的生长速率和出水浓度有关。在实验室规模的装置上研究了SRT对卡马西平去除的影响。然后在几个全尺寸装置上对这些测试结果进行了验证。由于缺乏合适的受纳水体和地下水资源，其中一个污水处理厂不得不将处理后的废水渗入非饱和土壤中。在此，在距渗透点等距离处采集地下水样本，以评估卡马西平在土壤渗透过程中和地下水中的行为。这种抗癫痫药物在环境中似乎非常持久，因此可作为水生环境中人为影响的合适标志物。
