| 摘 要： | 以产气量为指标测试了10种邻苯二甲酸酯的厌氧生物降解性状，发现随分子结构的变化，其厌氧终极降解速率和降解半衰期表现出较大差异，厌氧生物降解难易程度依次为：DMP：DEP〉DnPP〉DnBP〉DnAP〉〉DiHP〈DnOP=DINP〉DUP；将分子结构参数与降解速率、半衰期用SPSS进行多元回归分析表明邻苯二甲酸酯的分子结构是决定其厌氧生物降解性的关键因素，高分子量的化合物不利于厌氧生物降解．研究结果对其厌氧生物处理、生物修复具有一定的理论指导意义．

| Abstract: | Net biogas production(NBP) was used to judge the anaerobic biodegradability of 10 kinds of PAEs.It indicated that along with the change of the molecular structure,the anaerobic degradation rate and degradation half-life also changed.The relative biodegradation rate descended in the order DMP=DEP>DnPP>DnBP>DnAP>>DiHPDUP.A multiple regression analysis in SPSS was then carried out on biodegradation rates and biodegrad ation half-life and molecular structure parameters.It shows that the molecular structure is a key factor in biodegradation.The results provide directions to the anaerobic biology disposal and bioremediation. |
