Triclosan Removal in Large-Scale Constructed Wetlands (CWs) in Winter

  • 摘要: 为了明确北方大规模人工湿地在冬季对TCS(三氯生)的去除效果,在山东省境内4个典型的大规模人工湿地(即武河人工湿地、大沙河人工湿地、新薛河人工湿地和洸府河人工湿地)内于冬季(2013年12月—2014年1月)进行取样,以超高效液相色谱串联质谱法测定人工湿地进出水中ρ(TCS),并分析不同湿地对TCS的去除效果. 结果表明:TCS在4个人工湿地系统进出水中均有检出,由于各人工湿地系统均承接当地污水处理厂尾水,冬季进水中ρ(TCS)偏高,为(800.81±83.37)~(1 151.00±47.13) ng/L,并以武河人工湿地为最高. 虽然人工湿地对TCS的去除率达22.44%~78.82%,但经由人工湿地处理后出水中仍含有较高浓度的TCS残留,经由人工湿地出水进入下游水体的TCS日释放量仍较高,其中洸府河人工湿地出水中高达92.60 g. 因此,冬季各人工湿地对TCS的去除效果在低温影响下有所降低,并且对下游水体和人类健康的威胁不容忽视.
