The enteroviruses such as , , Hepatitis A virus, , and are mostly transmitted via water and are commonly seen in Turkey. Due to lack of regulations for monitoring these viruses at the discharge points of wastewater treatment plants (WWTPs), the discharges reach to surface waters causing water-borne diseases. This emphasizes the importance of WWTPs' removal capacities to minimize the spread of enteroviruses. To evaluate the removal capacities of enteroviruses, five different types of WWTPs from Ankara-Turkey were investigated over a year. Seasonal abundances of enterovirus-specific genes in both influents and effluents from each WWTP were determined by quantitative polymerase chain reaction (qPCR). The reduction of enteroviral nucleic acids in the effluent wastewater samples compared to the influent wastewater samples was assessed as the removal capacity in log reduction values (LRVs). The qPCR results revealed that among five different types of WWTPs tested, membrane bioreactors effectively removed alone with LRVs more than 3. The removal of , Hepatitis A virus, , and in WWTPs with varying processes was below LRV 3.
诸如 、 、甲型肝炎病毒、 以及 等肠道病毒大多通过水传播，在土耳其较为常见。由于缺乏在污水处理厂（WWTPs）排放点监测这些病毒的规定，排放物进入地表水，导致水传播疾病。这凸显了污水处理厂的去除能力对于最大限度减少肠道病毒传播的重要性。为了评估肠道病毒的去除能力，对土耳其安卡拉的五种不同类型的污水处理厂进行了为期一年的调查。通过定量聚合酶链反应（qPCR）测定每个污水处理厂进水和出水中肠道病毒特异性基因的季节性丰度。将出水废水样本中肠道病毒核酸相对于进水废水样本的减少量评估为以对数减少值（LRVs）表示的去除能力。qPCR结果显示，在所测试的五种不同类型的污水处理厂中，膜生物反应器单独对 的去除效果显著，LRVs超过3。不同工艺的污水处理厂对 、甲型肝炎病毒、 以及 的去除率低于LRV 3。
