国外发达国家滴灌发展迅速 ,主要原因之一是研究形成了比较完善的过滤技术和设备。目前国外只解决了一般水质的过滤问题 ,对高含沙水的过滤并没有根本解决。本文以国家“九五”攻关项目“内蒙阿左旗荒漠地区示范区建设与研究”为背景 ,提出水源动态状况下用高含沙水滴灌的四级过滤模式 ,经试运行测试 ,基本达到设计指标。 Rapid development of drip irrigation in developed countries, one of the main reasons is the formation of a relatively complete filtration technology and equipment. At present, foreign countries only solve the problem of filtration of general water quality, and there is no fundamental solution to the filtration of high silt water. Based on the project of “Ninth Five-Year” national key project “Construction and Research of Demonstration Zones of Aozuoqi Desert in Inner Mongolia”, this paper proposes a four-stage filtration model with high concentration of drip irrigation under dynamic conditions of water source. index.
