| 摘 要： | 微灌用新型沉沙池是一种新型泥沙处理设备,地表水资源经过它处理后可直接作为灌溉水源进入农田微灌系统。通过原型观测实验分析,对微灌用新型沉沙池的泥沙沿程分布情况和水流含沙量变化进行了研究。结果表明:相比传统沉沙池,新型沉沙池对泥沙的沉淀效果更明显,泥沙颗粒自池首至池尾的沿程分布表现出由大到小变化规律,且渠尾出池水流的悬移质含沙量明显减小,具有广阔的应用前景。

A Study on Removal Efficiency of New-type Sand Basin in Practical Project |

| Abstract: | New-type sand basin for micro-irrigation is new type disposal equipment .After deposed by the new-type sand-basin ,sur‐face water resource can be utilized directly as irrigation water for farmland micro-irrigation system .Based on prototype observation , sediment distribution along route and sediment concentration of the new-type sand basin has been analyzed .The results show that :compared with the traditional sand basin ,the new-type sand basin setting effect has better sedimentation efficiency ;the sediment particles distribution from the upstream to the downstream of basin shows the rule of changing from big to small ;and the suspend load sediment concentration significantly decreases in the end of sand basin ;so the new-type sand basin has a good application prospect . |
