废水中双酚类似物（BPs）的存在会对环境中的生物产生不利影响。然而，对医院和垃圾填埋场等废水来源以及BPs的去除的了解仍然有限。在中国南方的医院，垃圾填埋场，城市污水处理厂（WWTPs）的15个BP进行了调查。在不同来源的废水中检测到11种双酚A，双酚A（BPA）通常是主要污染物。在4家医院中，医院废水和处理后废水中的BPs（Sigma BPs）总浓度范围为122 - 1040 ng/L。在垃圾填埋场中，渗滤液和经处理的渗滤液中的Sigma BPs分别为32、130和145 ng/L。在5个城市污水处理厂中，Sigma BPs在进水中高达17，200 ng/L，在出水中为502 ng/L，在污泥中为291 ng/g。改良A（2）/O工艺对BPs的去除效果最好，而UNITANK工艺则没有优势。在中国南方广东省，医院处理的废水，垃圾填埋场处理的渗滤液和污水处理厂的污水，每年的质量负荷估计分别为630，9.46和4697公斤/年。在源流出物的风险商数值显示低至中等的雌激素风险接收河流。应采取控制措施，不仅从污水处理厂流出物中，而且从其他来源中进一步去除BPs。(C)2021爱思唯尔有限公司版权所有。
The presence of bisphenol analogues (BPs) in wastewater can have adverse effects to organisms in the environment. However, knowledge of the wastewater sources, such as hospitals and landfills, as well as the removal of BPs are still limited. Fifteen BPs were investigated in hospital, landfills, and municipal wastewater treatment plants (WWTPs) in South China. Eleven BPs were detected in various source wastewaters, and bisphenol A (BPA) is generally the dominant pollutant. In 4 hospitals, the total concentrations of BPs (Sigma BPs) in hospital wastewater and treated wastewater ranged from 122 to 1040 ng/L. In the landfill, Sigma BPs in leachate and treated leachates were 32,130 and 145 ng/L, respectively. In 5 municipal WWTPs, Sigma BPs was up to 17,200 ng/L in influents, 502 ng/L in effluents, and 291 ng/g in sludges. The modified A(2)/O process exhibited best removal profile for BPs, while the UNITANK process had no advantages. The annual mass load estimates of hospital treated wastewater, landfill treated leachate, and WWTP effluents in Guangdong Province, South China, were 630, 9.46, and 4697 kg/y, respectively. The risk quotient values in source effluents revealed lowto medium estrogenic risks to receiving rivers. Control measures should be applied to further remove BPs not only from WWTP effluents but also from other sources. (C) 2021 Elsevier B.V. All rights reserved.
