| 摘 要： | 探讨了一体式膜生物反应器中料液粘度变化的原因,以及料液粘度对膜过滤阻力的影响。试验结果表明:料液粘度的增加主要因反应器中累积的高浓度胞外聚合物(EPS)所致;污泥粘度随着EPS浓度的变化而变化,二者之间存在很好的相关性(r=0.9958);污泥粘度与膜过滤阻力有较好的相关性(r=0.9006)。

| Abstract: | The reason of the change of the sludge viscosity in submerged membrane bioreactor and the effect of the viscosity on the filtration resistance of the membrane were discussed.The results of the test showed that: high-concentration extracellular polymeric substances(EPS) accumulated in the reactor was the main reason caused the increasing of the sludge viscosity;the sludge viscosity changed with the variation of the EPS concentration,there existed a good relativity between the above two(r = 0.9958),and the relativity between the sludge viscosity and the filtration resistance of the membrane was also good(r = 0.9006). |
