针对黄河泥沙水大田微灌的严重堵塞问题，分析了国内外净化设备与设施现状与缺陷，提出了高含沙水微灌非全流过滤方法，设计了多种类型的排渗过滤装置以及与之配套的田间灌溉系统的典型布置．通过野外与室内试验验证，方法及装置可行，处理泥沙效果好，具有推广价值，为利用黄河高含沙水微灌开辟了一条新路． In view of the serious blockage of micro-irrigation in the Yellow River silt water field, the status quo and defects of purification equipment and facilities at home and abroad are analyzed, and the non-full flow filtration method of micro-irrigation with high concentration of sandy water is proposed. Various types of drainage filtration devices are designed With the accompanying field irrigation system typical layout. Through the field and laboratory tests, the method and the device are feasible, the treatment effect of sediment is good, and has the promotion value, which opens up a new road for using the micro-irrigation of the high sediment concentration in the Yellow River.
