| 摘 要： | 通过对升流式厌氧污泥床的流动分析，提出了用离散数Ｄ定量地表示筛分强度。通过实验和回归分析，建立了Ｄ与水力负荷（Ｌ）和沼气沼气容积产量（Ｇ）的数学关系：Ｄ＝０．００３３Ｌ＋０．０４５Ｇ＋０．０７３。当Ｄ在０．０８８－０．０９５之间，用生活污水作基质，成功地培养出了颗粒污泥。

| Abstract: | Through analysis of flow state in upflow anaerobic sluge bed, showed that the dispersion number D could be represented as selection pressure quantitatively. By experiment and regression analysis, the mathematical relation between D and hydraulic loading rate (L) and biogas production volumetric rate (G) was D=0.0033L+0.045G-0.073. Under D=0.088-0.095, the granular sludge would be formed when treated with domestic sewage. |
