树脂吸附法治理兰州新区灰土次生盐渍化试验研究

Experimental Study on Secondary Salinization of Lime Soil in Lanzhou New Area by Resin Adsorption Method

论文重点介绍掺入树脂后灰土易溶盐的减小情况。本试验是在查明了兰州新区灰土次生盐渍化机理的前提下进行的进一步试验,目的是用树脂治理次生盐渍化病害。通过试验发现了一种吸附树脂对盐渍土中的硫酸根离子有很好的吸附效果,故可以选择适宜的树脂吸附土中的SO_(4)^(2-),从而治理因SO_(4)^(2-)引起的土壤膨胀病害。

This paper focuses on the reduction of soluble salts in lime-soil after adding resin.This test is a further test under the premise of finding out the mechanism of secondary salinization of lime soil in Lanzhou New Area,and the purpose is to use resin to treat secondary salinization diseases.Through experiments,it was found that an adsorption resin has a good adsorption effect on sulfate ions in saline soil,so a suitable resin can be selected to adsorb SO_(4)^(2-) ions in the soil,so as to control the soil swelling disease caused by SO_(4)^(2-).
