【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。
[Abstract]:The new sand sink for micro-irrigation is a new type of sediment treatment equipment. Surface water resources can be directly used as irrigation water source to enter the micro-irrigation system. The distribution of sediment along the course and the change of sediment concentration in the flow of the new sediment basin for micro-irrigation are studied. The results show that the sedimentation effect of the new sediment pool is more obvious than that of the traditional sedimentation basin. The distribution of sediment particles from the top of the pond to the tail of the pond shows the law of variation from large to small, and the suspended sediment content of the flow in the outlet of the canal tail decreases obviously, which has a broad application prospect.

【正文快照】： 1研究背景新疆是农业灌溉用水大省,目前主要采用节水微灌技术进行大田灌溉[1-3]。因灌溉水源含有有机物、杂草、砂石、泥沙等各种杂质,故需要对灌溉水源进行过滤和净化处理措施才能进入滴灌系统,这是保证农田滴灌系统正常、安全、长期可靠的运行的重要前提保证[4,5]。在新疆农
