大化水电站漂浮污物综合治理方案探讨

Discussion on Comprehensive Control Scheme for Floating Pollutants of Dahua Hydropower Station

大化水电站由于上游随水流携带的生活垃圾、树枝等漂悬杂物甚多,引起机组进水口拦污栅堵塞而直接影响水电站的有效运行,文章针对大化水电站漂浮污杂物现状和存在的问题进行分析,提出"拦污+导漂+排漂+清污"相结合的综合治理方案,可供相似工程借鉴。

Generally, the riverbed hydropower station is located in middle and lower reaches. The blocking up of intake trash rack, due to domestic garbage, tree branches and other floating trashes carried by the water flow of upper and middle reaches, is a common problem in riverbed hydropower station, which may directly influence the effective operation of the station. The paper presents a comprehensive control scheme of ＂stopping ＋ guiding ＋ draining ＋ cleaning of floating trashes＂ based on the analysis on the problems resulting from the existing floating pollutants of Dahua hydropower station, which can be well reference by similar projects.
