摘要
用A2/O工艺,研究活性污泥接种培养工艺对活性污泥性能及污染物去除效果的影响。结果表明,在培养阶段,间歇式和连续式的MLSS、MLVSS分别为5 400,2 850,3 580,2 100 mg/L;运行阶段,污泥对COD、TN和TP的去除率分别为91.2%,87%,92%和89.5%,83%,72%,连续式优于间歇式。采用先间歇后连续方式培养污泥,能获得高活性污泥,缩短培养时间,有利于A2/O工艺启动和运行。
The activated sludge domestication was investigated by A^2/ O craft to affect the activated sludge performace and pollutants removal effect. The results show that MLSS and MLVSS of batch and continuous culture system in the culture period were 5 400,2 850,3 580,2 100 mg / L,respectively. The average removal rate of COD,TN and TP of batch and continuous culture system in the operation stage were 91. 2%,87%,92% and 89. 5%,83%,72%. The average removal rate of pollutants of and continuous was superior to batch system. High activity sludge could be obtained by batch and continuous in turn process,and domestication time could be shorten,which was good to the startup and operation of A2/ O craft.
