摘要
本文从理论上分析了平流直线型顺坡及逆坡沉沙池的水流特性及泥沙运动过程。结果表明,在池长相同的条件下,逆坡沉沙池的沉淀效率明显高于顺坡沉沙池,而且出池泥沙粒径也较细。文中分别给出了顺、逆坡沉沙池出池泥沙粒径之比和沉淀效率相同的条件下,二者池长之比的关系式。工程实例也表明了逆坡沉沙池具有良好的沉淀效率及冲洗效果。
The hydraulic properties and the course of sediment movement in settling basins of straight-line type with positive or reverse gradient slope are deseribed. It is found that the settling effect of back-slope basin is obviously higher than that of a positive slope one in the meanwhile the size of particles out ofthe basin is also smaller. Existing practical engineering examples also shown that the back-slope settling basin is of good effects.
