| 摘 要： | 通过对西安市北石桥污水净化中心DE型氧化沟不同断面、不同水深处的水质指标测定分析，了解到沟内的混合液基本上处于完全混合状态，氧化沟高效率脱氮除磷的原因在于高浓度、高活性污染对水中污染物的迅速吸附和沟内污泥的高度稳定性。

| Abstract: | Through an investigation of water quality parameters at different cross section and different depth, it was revealed that liquid is almost completely mixed in the DE type oxidation ditch in Beishiqiao Wastewater Purification Center, Xi'an. The high efficiency of nitrogen and phosphorus removal is resulted from fast absorption of pollutants by the high sludge concentration and activity in the ditch. |
