在某污染的工业废物填埋场环境水文 地质评价中的同位素水文学研究

本文论述了某污染的工业废物填埋场场址的地质、水文地质条件,应用水化学方法、环境同位素技术(地下水中氚及氢、氧稳定同位素)和同位素单孔示踪技术等同位素水文学领域中的新方法对区内地下水的活动条件以及填埋场场址区分布的第四系孔隙潜水和第三纪红层孔隙-裂隙水的成因进行了分析,测量并确定了填埋场下部地下水的流速及流向。研究结果表明场区地下水的运动与地表水无直接水力联系。污染的工业废物填埋后不会通过地下水的迁移造成对地表水的污染,进而证实填埋场的地质、水文地质条件对处置污染的工业废物是安全可靠的。

A STUDY OF ISOTOPE HYDROLOGY ON ENVIRONMENTAL HYDROGEOLOGICAL ASSESSMENT OF A DISPOSAL SITE FOR CONTAMINATED INDUSTRIAL WASTES

This paper describes the geological-hydrogeological conditions of a disposal site for contaminated industrial wastes. Some new methods in the field of isotope hydrology such as hydrochemical method, environmental isotopic techniques(tritium, hydrogen and oxygen stable isotopes in waters)and radioisotopic single borehole tracing techniques were applied to investigate the groundwater movement in the area. The sources of Quaternary pore phreatic water and Tertiary red bed pore-fissure water have been distinguished and groundwater flow rate and flow direction under the disposal site have been measured and determined. The obtained data show that the movement of groundwater is not hydraulically related to surface water. The disposal of contaminated industrial wastes will not cause the pollution of surface water through groundwater migration. The above-mentioned information demonstrates that the geological and hydrogeological environments are safe and reliable for disposing contaminated industrial wastes.
