  • 摘要: 采用固相萃取-气相色谱法研究了邯郸某污水处理系统污水和污泥中内分泌干扰物的存在水平,在污水和污泥中均检测出多氯联苯类、多环芳烃类、邻苯二甲酸酯类、酚类和有机氯农药五大类内分泌干扰物,除多氯联苯浓度在μg水平外,其他4种内分泌干扰物的浓度均在ng水平。污水处理系统进水以及污泥中它们的平均浓度分别在19.43 ng/L~60.82 μg/L和43.94 ng/g~167.45 μg/g之间,污水经过处理后,平均去除率在16.6%~77.9%之间。在污水处理过程中,多氯联苯、多环芳烃和有机氯农药主要通过污泥吸附去除,而邻苯二甲酸酯和酚类则主要通过生物降解作用去除。
    Abstract: Solid-phase extraction-gas chromatography was used to analyze the existence of endocrine disruptors in sewage and sludge of a sewage disposal system in Handan, China. The following five categories of endocrine disrupting chemicals (EDCs) were detected: polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), phthalates (PAEs), phenols, and organochlorine pesticides (OCPs). All concentrations of endocrine disruptors were present at levels expressed in ng except for PCBs, which were at the level of μg. Average concentrations of the five EDC categories in sewage and sludge were between 9.43 ng/L to 60.82 μg/L and 43.94 ng/g to 167.45 μg/g, respectively. Following treatment, the average removal rate of the five EDC categories was between 16.6% to 77.9%. In the process of sewage treatment, PCBs, PAHs, and OCPs were mainly removed by sludge adsorbing. However, PAEs and phenols were mainly removed by biodegradation.
