| 摘 要： | 针对黄河水微灌泥沙含量高、极易堵塞灌水器的难题,开展了黄河宁夏段泥沙特性、高效节水灌溉工程配套沉沙、调蓄水池水质净化,组合过滤器泥沙去除、水质净化研究。在对大量工程运行效果监测研究的基础上,提出了不同蓄水池规模、黄河水进入蓄水池沉淀时间、组合过滤器水质净化效果,同时结合宁夏引扬黄灌区特点,推荐黄河水微灌水质净化处理模式为渠道→预沉池→调蓄池→泵站前池→加压泵站→首部砂石+叠片过滤器或筛网+叠片过滤器→输水管网→配水管网→灌水器,可为宁夏高效节水灌溉工程建设提供技术支撑。

| Abstract: | In view of the problems of high sediment concentration of Yellow River and the emitters being easy to be blocked, the research on the sediment characteristics in Ningxia section of the Yellow River, the matched desilting facilities for efficient water-saving irrigation engineering, the water quality purification of the storage pond and using composite filters to remove silt and purify water, is conducted in this paper.On the basis of the monitoring data of the operating effects of large project, different reservoir scale, precipitation time for Yellow River water in the storage pond and the water quality purification effect of composite filters are put forward.Moreover, combining with the characteristics of Yellow River irrigation districts in Ningxia, the water quality purification treatment process for micro-irrigation is recommend as from the channel, pre-sedimentation pond, storage pond, forebay of pumping station, pump station, the head grit filter with laminated filter or screen filter with laminated filter, water distribution pipe network, to irrigation emitter, which can provide technical support for efficient water-saving irrigation project construction in Ningxia. |
