摘要
未经处理的污水可通过直接排放或渗漏进入地表水,严重威胁到生态安全和人类健康。探寻污水特征指标,检测污水来源,具有重要意义。医药品与个人护理用品(PPCPs)是一类环境新兴污染物,与人类活动联系密切,具有良好的污水源特性。本研究采集了3个不同处理工艺的污水厂的进水和出水,分析50余种PPCPs的浓度,研究污水处理工艺对其的去除效果,筛选特征污水指标,并采集河口样品,研究河口区水体受污水污染的情况。结果表明,对乙酰氨基酚、咖啡因、对羟基苯甲酸甲酯、对羟基苯甲酸丙酯、布洛芬、双酚A等在污水厂具有较高的去除率,将其作为易去除的示踪剂,而双氯芬酸、美多洛尔、三氯卡班等难以去除,作为难去除的示踪剂,通过计算以上2组浓度的比值(R),反应自然水体受污染情况。如图1a可见,河口区的R值高于污水厂出水的R值,表明广泛存在未经处理而直接排入的污水。NMDS(图1b)分析表明,进水和出水具有明显差异性,而河口水体分布于其中间,表明河口水受到未经处理而直接排放的污水影响。
The occurrence and fate of 50 pharmaceuticals and personal care products(PPCPs) were investigated in the influent,effluent of 3 wastewater treatment plants.Acetaminophen,caffeine,bisphenol A,ibuprofen,methyl paraben,and propyl paraben were labile during the wastewater treatment processes,while metoprolol,triclocarban,and diclofenac were conservative.These PPCPs were selected as sewage markers.The occurrence of PPCPs in Jiulong River estuary was investigated.The ratio between labile to conservative PPCPs and non-metric multidimensional scaling(NMDS) indicated the ubiquitous discharge of untreated wastewater in the Jiulong River estuary.
