摘　　要：微灌作为一种节水灌溉方式,在国内外水资源紧缺地区已得到广泛应用。微灌用过滤装置作为微灌系统的核心,其重要性日益凸显,而其所带来的经济效益亦受到广泛关注。本试验针对一种已在实际工程上应用的新型组合式过滤器,对其进行了水力性能分析,以指导该装置的实际工程应用。试验表明新型组合式过滤器过滤性能与传统单一旋流过滤器相比有明显提升;与单一网式过滤器相比,其反冲洗间隔明显延长。当流量大于等于100m3/h时,其压降随时间变化曲线表现为双段式。Micro-irrigation as a way of water-saving irrigation has been widely used in water-shortage areas at home and abroad .Mi‐cro-irrigation filtering device is used as the core of micro-irrigation system .Its importance is increasingly prominent ,and its economic benefits have also attracted much attention .This experiment is targeted at a new kind of composite filter ,which has been in practical engineering application ,and an analysis is made of the filtration performance to guide the practical engineering application of the de‐vice .Experiment shows that the performance of the new composite filter compared with the traditional single spiral flow filter is im‐proved significantly .Compared with the single screen filter ,its backwash intervals have extended obviously .
