钠吸附比值法评价农田灌溉用水水质
首发时间:2009-10-26
摘要:介绍了钠吸附比值法及其评定标准。进一步用钠吸附比值法对渭河北岸傍农田潜水灌溉用水水质进行评价。由该区域潜水中的钠离子毫克当量,钙离子毫克当量和镁离子毫克当量求出钠吸附比值A,再由Surfer软件依据标准画出分区图。从分区图上看出研究区的钠吸附比值A均小于8,属于相当安全的水,故单从钠吸附比值评价来看该地区的潜水是可以被用来灌溉的。

The method used sodium adsorption ratio to evaluate
Abstract:This passage introduced the method of sodium adsorption ratio and the standards of assessment. This method is used to evaluate the quality of irrigation water in north of weihe. We obtained sodium adsorption ratio A from sodium ions, calcium ions and magnesium ions in phreatic groundwater of this region and then used the Surfer software draw out zoning chart based on standards. From the zoning chart we know sodium adsorption ratios are less than 8 and the water is quite safe. So phreatic groundwater of this region can be used for irrigation only from the value of sodium adsorption ratio.
Keywords: diving irrigation sodium adsorption ratio Water Quality Assessment
