金泽水库拦污排与格栅清污机的组合应用

The Combination Application of Floating Trash Rack and Grille Trash Cleaner in Jinze Reservoir Project

针对金泽水库工程引水河道短期内污物量增大的特点,提出了在引水河道进口处分别布置浮式拦污排与回转式格栅清污机、进行组合式拦污清污的方案,并阐述了浮式拦污排和回转式格栅清污机的设计要点。工程自运行以来,拦污排与清污机的组合应用能够及时有效地拦截和清除流道污物,收效良好,为平原河网地区类似工程提供了可借鉴的经验。

In view of the characteristics of the increase of the amount of sewage in the diversion channel of Jinze Reservoir Project in a short period of time,three schemes of installing floating trash rack,rotary grille trash cleaner and the combined sewage cleaner at the inlet of the diversion channel is proposed. The main design points of floating trash rack and rotary grille trash cleaner are described in this paper. Since the operation of the project,the combined application of trash rack and trash cleaner can effectively block and remove the sewage in the flow canal in time. The result of the project is good,which can be used as reference for similar projects in the plain river network area.
