某小型水厂山涧取水和原水输水管道排污设计

The design of mountain stream water intake and sewage discharge of raw water pipeline for a small water plant

在某工程设计时,把提高山涧取水安全、取水水质和原水输水管泄水排污能力作为设计重点。在取水设计时,选择山涧小潭为取水点,用过滤管方式取水,对取水坝和过滤管进行了针对性设计。在泄水排污设计时,分析了泄水排污水力特征,放大泄水管管径,对泄水点处阀门设置和排污冲洗方式进行创新设计,探讨了泄水排污的周期问题。

In the design of a certain project,the improvement of the safety of mountain stream water intake,the quality of water intake and the discharge and sewage capacity of the raw water pipeline is the design focus.In the design of water intake,the mountain stream small pool has been selected as the water intake point,and the filter tube has been used to draw water,the intake dam and filter tube have been designed pertinently.In the design of water discharge and sewage,the characteristics of water discharge and sewage have been analyzed,and the diameter of the drainage pipe has been enlarged,the valve setting at the discharge point and sewage flushing method have been innovatively designed,and the problem of the discharge and sewage cycle has been discussed.
