摘　　要：研究在葡萄糖作为共代谢基质时酸性媒介黑T,派拉丁兰RRN的降解情况.结果表明,在厌氧微生物的作用下,酸性媒介黑T、派拉丁兰RRN还原氮氮双键效果较好,酸性媒介黑T、派拉丁兰RRN的厌氧降解都符合零级动力学方程.其反应速率常数K分别为0.2238mg/(h·L)和0.2652mg/(h·L);半衰期分别为34h和35h,在同样条件下派拉丁兰RRN的厌氧降解比酸性媒介黑T降解快.The degradation states of Acid Complex Black T and Mordant Blue RRN were studied in this paper with glucose as cometabolism substrate. Under the anaerobic microbe action, the effects of deazo reduction of Acid Complex Black T and Mordant Blue RRN were better; their anaerobic degradations all coincided on zero order kinetics equation. Their reaction rate constants K was 0.2238mg/(h?L) and 0.2652mg/(h?L) respectively; half-life was 34h and 35h respectively. The anaerobic degradation rate of Mordant Blue RRN quicker than that of Acid Complex Black T under same conditions.
