摘要：
分别以厌氧产甲烷污泥（AMS）、新鲜厌氧氨氧化污泥（FAS）和储藏厌氧氨氧化污泥（SAS）作为接种物，研究了厌氧氨氧化膨胀颗粒污泥床（Anammox-EGSB）反应器启动过程中的污泥性能。结果表明，3种接种物启动Anammox-EGSB反应器的有效性为：FAS＞SAS＞AMS；启动过程中3种接种物的生物含量（VSS/SS比）上升，污泥粒径增大，沉降速度加快，反应活性提高，颜色趋向鲜红，Anammox性能逐渐改善，细胞悬液在
Abstract:
The characteristics of the anaerobic sludges in Anammox-EGSB bioreactors started up with anaerobic methanogenic sludge(AMS), fresh Anammox sludge(FAS)and stored Anammox sludge(SAS)were investigated respectively.It was found that Anammox-EGSB bioreactors could be started up successfully with these three kinds of seeding sludges.The performance of the bioreactor inoculated with SAS was better than that inoculated with AMS, but worse than that inoculated with FAS.After the start-up, the VSS/SS ratio, granular diameter, settling velocity and SAA of these three seeding sludges were superior to those of the initial state.The color of three seeding sludges tended to be bright red.Besides, the cell suspension showed the characteristic absorption peaks between 400 nm and 420 nm.The changes on color and the absorption spectrum of the sludges were correlated with the changes of numbers and the activity of microorganisms during the start-up.The color and absorption spectrum could be used as an indicator in the start-up of Anammox reactors.
