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.

Abstract:
Abstract: In order to research the removal efficiency of triclosan (TCS) in the large-scale constructed wetlands (CWs) in winter, the occurrence of TCS in the influent and effluent water from four CWs (Wu River CW, Dasha River CW, Xinxue River CW and Guangfu River CW) were investigated from December 2013 to January 2014 in Shandong Province, China, by using the UPLC-MS/MS. All the CWs were detected with TCS in both influent and effluent waters. As the influent water of CWs was from the local wastewater treatment plants, the concentration of TCS was (800.81±83.37)-(1151.00±47.13)ng/L, and the highest value occurred in Wu River CW. Due to the high concentration of TCS in the influent water, high TCS residue was detected in the effluent water although the removal efficiency of TCS was 22.44%-78.82%. According to further calculation, the daily input from those CWs to downstream water resources was considerably high in winter. And it was estimated to be 92.60 g in Guangfu River CW. In conclusion, TCS removal efficiency was affected by the cold weather in winter, and the threat to downstream water as well as human health must be paid attention to.
