| 摘 要： | 以北京城区4座不同处理工艺的再生水厂进出水为研究对象,采用固相萃取(SPE)预处理和气相色谱-质谱法(GC-MS)方法对再生水标准中涉及到的邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二(2-乙基己基)酯(DEHP)两类污染物进行了检测,对比分析不同再生水处理工艺的去除效果。结果表明,各水厂进水中DBP和DEHP的浓度范围分别为1.99～5.36μg/L和0.97～6.44μg/L,与上游污水处理厂所采用的处理工艺无明显关联性;出水中DBP浓度为1.74～5.59μg/L,DEHP浓度范围0.42～4.93μg/L,均低于景观环境用水的国家标准限值;常规混凝-过滤-消毒处理工艺的去除效果并不明显,而膜工艺由于膜污染等实际运行问题也没有达到理想去除效果,去除率不足60%。

| Abstract: | Influents and effluents of four reclaimed water plants with different treatment processes in Beijing were studied.Both dibutyl phthalate(DBP)and Di(2-ethylhexyl)phthalate(DEHP)involved in reclaimed water standards were detected by solid phase extraction(SPE) for pretreatment and gas chromatography-mass spectrometry(GC-MS).And removal effects of different treatment processes for reclaimed water were analyzed contrastively.The results showed that the water plant influent concentrations of DBP and DEHP were in... |
