高含沙水微灌非全流过滤方法及装置研究

Study on Non all flow Filtering Method and Devices for Micro irrigation with High silt Content Water

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．

Aiming at the serious pluging problem of micro irrigation with high silt content water from the Yellow River,and on the basis of analysing the present situation and the defect of purified equipment at home and abroad,the author invented the non all flow filtering (shortened NAFF) method for micro irrigation with high silt content water,designed many types of NAFF devices and the typical layout of irrigation system.The outdoor and indoor experiments verify that the invented method and devices are feasible and have popularizing value.It is a new way for micro irrigation with high silt content water from the Yellow River.
