| 中文摘要 |
| 为分析和比较印染废水处理中“物化+生化”和“生化+物化”2种耦合工艺的优缺点，应用气相色谱-有机质谱联用仪（GC-MS）分析了2种耦合工艺在印染废水处理中有机物的降解过程，并对物化污泥和排放水体中的有机污染物进行了检测.结果表明，“物化+生化”工艺对有机物的降解效果不如“生化+物化”，后者对各类污染物的平均去除率比前者高6.2%，主要差别体现在厌氧水解工艺的作用效率上.此外，“物化+生化”工艺导致印染废水中典型有机污染物向物化污泥以及排放水体中迁移，容易引起二次污染. |
| 英文摘要 |
| In order to analyze the advantages/disadvantages of the combined treatment process between “physicochemical+biochemical” and “biochemical+physicochemical” in treatment of textile wastewater, gas chromatography-mass spectrometry(GC-MS) was used to determine the degradation process of organic pollutants in this two totally different treatment processes. The same analysis was also conducted to the sludge and discharged water. The results showed that the “physicochemical+biochemical” process displayed a poorer effect than “biochemical+physicochemical” in degrading the organic pollutants. The latter was 6.2% higher than the former in removing the organic pollutants averagely. The difference was mainly manifested in the efficiency of anaerobic hydrolysis in the two coupled processes.Moreover, the implement of “physicochemical+biochemical” process resulted in the migration of plenty of typical organic pollutants to sludge from primary coagulation sedimentation process and to the discharged water, which would cause secondary pollution easily. |
