中文摘要：

以两种不同结构的絮状污泥（有丝状菌和无丝状菌）为接种污泥，在SBR反应器中利用水力选择的方法培养具有除磷能力的颗粒污泥。结果表明，两种污泥分别在第10天（有丝状菌）和第43天（无丝状菌）时开始颗粒化，运行了20d和82d后颗粒化完全；所形成的颗粒污泥粒径（均为0．5～1mm）和污泥沉降性能（SVI值均在30mL／g左右）无明显差异，但污泥的形态和活性存在显著不同。此外，在污泥由絮状向颗粒状转化的过程中，其含水率和部分金属元素的含量明显降低。

英文摘要：

Using flocculent sludge with/without filamentous bacteria as seed sludge, granular sludge with phosphorus removal capability was cuhivated in SBR. The results show that the sludge granulation starts on the 10^th day for sludge with filamentous bacteria and on the 43^rd day for sludge without filamentous bacteria, and is complete on the 20^th and 82^nd days, respectively. For both kinds of flocculent sludge, the diameter of the formed granular sludge is 0.5 to 1 mm and SVI is 30 mL/g, but the differences in the sludge morphology and activity are significant. In addition, the concentrations of water and metal elements in the granular sludge obviously decrease during sludge granulation.
