摘要
采用便携式气相色谱-质谱联用仪对石化污水处理场排放的挥发性有机物的排放状况进行了测定。检测出的挥发性有机物中以烷烃和芳香烃为主,总浓度随污水处理工艺流程逐级降低。芳香烃的质量分数为33.23%～84.73%。
A portable gas chromatography and mass spectrometry（GC-MS） was carried out to study the volatile organic compounds（VOCs） exhausted from wastewater treatment system of petrochemical refinery.The result shows that alkanes and aromatics account for large percentage.The percentage of the aromatics is 33.23% ～ 84.73%.The concentration of the VOCs decreases as the wastewater is treated.
