摘　　要：　为了确定无盐、含25g/L盐度和35g/L盐度活性污泥系统的最大抗盐度冲击范围而进行了试验。结果表明,上述3系统的最大抗盐度冲击范围分别是0～20、5～30和15～35g/L。当处理系统受到盐度冲击时,普遍会出现有机物去除率下降、出水悬浮固体浓度升高、污泥大量流失等现象,但是当进水盐度恢复到初始值且保持稳定,有足够长的恢复时间,则系统的处理效果可以恢复。Experiment was made to determine the maximum resistance to salinity shock in activated sludge systems with salt content of zero, 25 g/L, and 35 g/L respectively . The result showed that the maximum resistance to salinity shock of the three systems above mentioned is in the range of 0～20, 5～30, and 15～35 g/L respectively. When the systems are subject to the shock of salinity, the phenomena such as decrease of organic removal, rising of effluent SS concentration, and washout of lot of sludge will occur. However, when the influent salinity is allowed to return to initial value and is kept stable, the treatment effect of the system can be recovered after enough time.
