摘　　要：为了考察高盐污水生物处理过程中营养污染物的去除效果及盐度对去除率的影响,试验选用革新MUCT工艺在稳定盐度下对淡水污泥进行驯化后,对盐度约为10 g/L的实际含盐污水进行处理.结果表明,系统对总无机氮和P的平均去除率分别为87%和72%;在不同盐度冲击下,系统对有机物和N、P的去除特性也不同,盐度冲击对有机物和N的去除影响较小而对P的去除影响较大,高盐度的冲击影响远大于低盐度的冲击影响.In order to find out the removal efficiency of nutrient pollution of real saline sewage and the influence of salinity shock, a lab-scale nutrient removal activated sludge system, based on the MUCT configuration, is modified to treat 10 g/L saline sewage. The results indicate that after domestication of microorganism at 10 g/L salinity, the total organic nitrogen and phosphorus average removal efficiency can achieve 87% and 72 % respectively. The nutrient removal efficiency was also changed under different salinity shock. The salinity shock, especially increased salinity shock, influences phosphorus removal efficiency much more than the removal efficiency of nitrogen and organic matter.
