折板絮凝是我国研究开发的高效水力絮凝工艺，但水头损失计算方法还不完善，计算值与实测值误差比较大。通过理论分析及模型试验，探寻了针对异波折板絮凝单元的水头损失半经验半理论计算公式
Flake flocculation is a high-efficiency hydraulic flocculation process researched and developed in China, but the head loss calculation method is not perfect, and the error between the calculated value and the measured value is relatively large. Through theoretical analysis and model tests, the semi-empirical and semi-theoretical calculation formula for the head loss of the folded plate flocculation unit is explored.
