介绍了三峡水利枢纽拦污和排污的研究成果和设计所采取的工程和调度措施。试验研究表明，其效果较为满意。即使在最低库水位１３５ｍ运行，拦污栅被部分堵塞时，也不会影响电厂正常引水发电，但必须重视厂前特别是右电厂前的清污。 The research results and the engineering and scheduling measures adopted by the Three Gorges Project are introduced. Experimental studies show that the effect is more satisfactory. Even when the minimum reservoir water level is 135m, the trash rack is partially blocked, it will not affect the normal power plant hydropower generation, but must pay attention to the factory before, especially right before the plant clean-up.
