| 摘 要： | 以盐度约2%的某制药废水为对象,考察了盐度分别降低至1/2、1/4、1/8后COD去除率、MLSS、MLVSS的变化以及VSS/SS与盐度的关系。结果表明,降低盐度不能提高COD的去除率;微生物主要通过排出细胞内的无机组分来适应盐度的降低;VSS/SS与盐度的对数呈线性关系。 |
| 关 键 词： | 活性污泥法 盐度 COD去除 |

| Abstract: | Pharmaceutical wastewater with salinity of 2% was chosen and the COD removal rate,change of MLSS and MLVSS concentration,as well as the ratio of VSS and SS were investigated by decreasing salinity to 1%,0.5% and 0.25%,respectively.The results showed that COD removal rate can't be increased after decreasing salinity.Microorganisms were easily adapted to salinity decreasing by discharging inorganic components from their cells.The ratios of VSS and SS were presented linear relationship with salinity. |
| Keywords: | Activated sludge method Salinity Removal of COD |
