摘要
无阔滤池反洗用虹吸管传统的静态设计方法,是造成反洗效果不佳的原因之一.为了在水箱水位变化的水力条件下,使滤床取得最佳的反洗效果,采用阻力特性曲线绘图法求得的虹吸管组合管径,可反映反洗全程的动态工况,使无阀滤池滤床处在反洗强度的有效区内工作.
The conventional rest design method for the valveless filter backwash si- phon is analyzed and believed to be one of the factors for its poor effect.In this paper, the drag characteristic curve graphic method is adopted to design the combined siphon diameters which can reflect backwash history of flow condition and enable the valveless filter bed backwash work effectively.
