七格三期污水处理厂转鼓式细格栅的改造与运行

Reconstruction and Operation of Drum Type Fine Screen in Qige PhaseⅢWastewater Treatment Plant

细格栅对于污水处理厂的稳定运行起着重要作用。针对七格三期污水处理厂转鼓式楔形网细格栅运行中遇到的问题,将转鼓式楔形网细格栅改造为转鼓式内耙齿细格栅,并对改造后的运行效果进行了评估,可为同类细格栅的选型与运行提供参考。

Fine screen plays an important role in stable operation of WWTP.In this paper,the problems encountered in the operation of drum type fine screen in Qige PhaseⅢWastewater Treatment Plant were analyzed.The drum type wedge grid fine screen was reconstructed to inner rake tooth fine screen,and the operation effect after reconstruction was evaluated.It can provide reference for the selection and operation of similar fine screens.
