摘　　要：堰式回收技术在海上溢油污染治理中应用广泛。应用堰过流理论对堰式撇油器中回收堰的过流性能进行分析,确定薄壁回收堰发生过流不稳而导致回收效率变差的原因,提出应用曲线形实用堰代替薄壁堰以改进回收堰的过流稳定性和回收速度,并给出曲线形实用堰的设计方法,为堰式撇油器实现溢油的快速高效回收奠定了理论基础。Weir recovery technology has been widely used in dealing with marine oil spill. The theory of weir flow is presented to analyze discharge capacity of recovery weir in weir skimmer,and the reason of flow instability,which occurs to thin-walled recovery weir and results in decreased recovery efficiency,is ascertained. The curved practical weir is presented to enhance flow stability and recovery rate of thin-walled recovery weir,and design method of curved practical weir is provided,which lay the theoretical foundation for achieving more rapid and efficient oil spill recovery by weir skimmer.
