试验证明,山形斜管具有沉淀所需要的良好水力条件,处理原水浊度范围较广等优点。本文提出了山形斜管构造参数的选用意见;做了山形斜管与正六角形斜管的对比试验研究;给出了山形斜管的水力特性参数公式,为山形斜管的实际应用提供了理论依据。

Research results show that chevron-shaped tube has adva-ntages of better hydraulic condition needed for sedimentation and adapta-bility for treatment of raw water turbidity.This paper points out the wayto select the construction parameters of chevron-shaped tube.The contrastresearch between chevron-shaped tube and honeycomb-shaped tube has beendone.The formula of hydraulic characteristic parameter of chevron-shapedtube is given.This formula sets out a theoretic base for practical applicationof chevron-shaped tube.
