摘要
研究了污水厂剩余污泥在不同pH、SS时对染料吸附的影响。结果显示pH值是决定染料吸附的最重要的因素,随着pH值的降低吸附量明显增大。在SS小于1g/L时,吸附量较大;但在SS大于1g/L时,吸附量则相对变化不大。应用多层吸附模型可计算吸附吉布斯焓变和单层吸附量,进而可以求算不同污泥颗粒的比表面积。
The dye absorption characteristics of sludge particulates were studied. Major factors such as pH and SS on dye absorption wereevaluated. Results show that pH is the most important factor determining the dye absorption. Decreasing pH can significantly increase theabsorption of the dye. Greater absorption density can be achieved with SS less than 1 g/L. However, with SS concentration greater than 1 g/L, thedye absorption density remains relatively unchanged. The multilayer absorption model allows the calculation of both the monolayer absorptiondensity and standard free energy change. It is possible to determine the specific surface area of various sludge particles.
