摘　　要：通过对邯郸市西污水处理厂改良型氧化沟的流态进行测试,得出了氧化沟系统各直沟道和弯道处的流速分布规律;分析了该氧化沟系统内的积泥原因,提出了相应的改进措施和建议;在出水水质达标的前提下,可获得曝气转碟和水下推动器的最优组合方式,以期达到节省运行费用、降低能耗的目的。By testing the flow pattern of modified oxidation ditch adopted by Western Wastewater Treatment Plant in Handan City, the velocity distribution rule in straight sections and curved sections of the oxidation ditch was gained. The reasons why sludge deposit exists in the oxidation ditch were analyzed, and the relevant improvement measures and suggestions were put forward. Based on the standard discharge of the effluent, the optimal combination schemes of aeration disks and submerged flow drivers can be obtained to save the operation cost and reduce the energy consumption.
