| 摘 要： | 通过现场模拟试验,探讨了雾化管、射流器、橡胶坝和叶轮4种曝气工艺对改善佛山水道水质的影响。结果表明,4种工艺的平均复氧效率(14.3%~36.6%)和对COD的平均去除率(9.6%~24.6%)显示了较大差异。橡胶坝和雾化管曝气工艺的复氧效率较高,而叶轮和射流器曝气工艺则对COD去除有较好效果。在曝气并结合混凝的对照试验中,投加絮凝剂有助于提高水中DO和去除COD。

| Abstract: | Based on spot simulative experiments,it was explored that the impacts of the four different aeration techniques(atomizing pipe,rubber dam,ejector and impeller aeration) on improving water quality of Foshan River.Results showed that average aeration efficiency(from 14.3% to 36.6%)and removal rate of COD(from 9.6% to 24.6%)presented great differences in four techniques.Atomizing pipe and rubber dam aeration techniques had a higher aeration efficiency.Impeller and ejector aeration techniques had a good effect ... |
