摘　　要：该文结合山东华能日照电厂二期(2×680MW)工程运行调试中遇到的循环泵启动瞬间排水系统壅水较为严重的问题,运用数学模型计算对直流循环排水系统壅水现象进行分析,得出了循环水排水井井顶、虹吸井井顶的计算设计标高,提出了减少壅水的改进措施,为以后直流循环排水系统减少壅水设计提供经验。Combined with the problems that backwater of drainage system upon instantaneous startup of a circulating pump seriously existed in commissioning and operation of Shandong Huaneng′s Rizhao Power Plant Phase II Project（2×680MW）,the backwater drainage system of DC circulating water was analyzed by using a mathematical model calculation.Then the calculation design elevation of the well top of the drainage well and siphon well were obtained,and some improvement measures on reducing backwater were proposed,which could provide experiences for reducing backwater on future designing of a DC circulating water system.
