Research on the water-rock interaction of the ash water and the basal Middle-Ordovician limestone under the red-mud yard in Zhongzhou Aluminum

Department of Materials Engineering, Luoyang College of Technology

摘要

摘要: 以焦作中铝一期赤泥堆场为研究对象,利用室内淋溶试验模拟了在冲灰水的作用下,赤泥附液及冲灰水中的不同污染物质(总硬度、氯离子、硫酸根离子、氟离子等)在向地下水运移过程中的水岩作用。结果表明,赤泥附液及其冲灰水在入渗的过程中,通过运移积累、溶解、吸附和离子交换等水岩作用对地下水造成污染,可溶盐溶解作用的动力学特征为:在试验初期,溶解速率大,而后逐渐减小,直至趋于零;赤泥灰水入渗过程中水岩作用的特点是,在试验初期表现为以溶解作用为主,而后以离子交换作用为主。

Abstract: Taking the red-mud storage yard of Zhongzhou aluminum in Jiaozuo as the research object, the water-rock interaction during the transportation of the pollutants, total hardness, chloride ion, sulfate ion, fluorine ion etc. that adhered in the red-mud towards the ground water is stimulated by means of indoor leaching test. The results prove that the ground water is polluted through the rock-water interaction of transportation, accumulation, dissolution and adsorption as well as ion exchange during the infiltration of the liquid that adhered to the red-mud and the ash water. The dynamics of the dissolution of soluble salts is characterized as that the dissolving rate is large at the beginning of the test and then decreases gradually, until tends to zero. The water-rock interaction during the infiltration of ash water is predominated by dissolution in the early period of the test and then by ion exchange.
