The removal of 12 pharmaceuticals and personal care products (PPCPs) in two full-scale wastewater treatment plants (WWTPs) and a tertiary treatment system was studied. The ecological risks of effluents from both secondary and tertiary treatment systems as well as excess sludge were evaluated. Primary treatment and ultraviolet light disinfection showed limited ability to remove most selected PPCPs. The combination of an anaerobic process and triple-oxidation ditches can eliminate DEET better than the anaerobic/anoxic/oxic process. Adsorption to sludge played a key role in the removal of triclocarban. Multistage constructed wetlands as a tertiary treatment efficiently removed caffeine and ibuprofen from wastewater and could decrease the risk of partial selected PPCPs. Selected PPCPs residues in excess sludge generally produced higher risks to the ecological environment than effluents from WWTPs.
研究了两种全规模污水处理厂（WWTP）和三级处理系统中 12 种药物和个人护理产品（PPCPs）的去除情况。评估了二级和三级处理系统以及剩余污泥的废水的生态风险。初级处理和紫外线消毒对大多数选定的 PPCPs 的去除能力有限。厌氧工艺和三氧化沟的组合可以比厌氧/缺氧/好氧工艺更好地去除 DEET。污泥吸附对三氯生的去除起着关键作用。多级人工湿地作为三级处理可以有效地从废水中去除咖啡因和布洛芬，并降低部分选定 PPCPs 的风险。剩余污泥中选定的 PPCPs 残留通常比 WWTP 废水对生态环境产生更高的风险。
