生物滤池旋转布水装置的设计

Study on Design for Turning Spurt Water Device Used for Biologic Filter

对旋转布水器中的水头变化进行了研究,对现有的水头计算公式进行了讨论。指出:只有当布水横管直径D≥60mm时,才能将其视为一等压体,当D<60mm时,水头的沿程变化较大,可按本文给出的计算公式进行旋转布水器的设计计算。

Hydraulic drop of turning spurt water device is studied, and the existing formula of hydraulic pressure is discussed. It is pointed out that, when the horizontal pipe's diameter D≥60mm, it is can be regarded as a isotonic system; while D < 60mm, the hydraulic drop along the pipe is greater, the design and calculate for turning spurt water device should be done with the formula presented in this text.
