若干冶炼砷渣(场)周边水环境特征研究

Characteristics of peripheral water environment of arsenic smelting slag(dump)

对冶炼砒霜产生砷渣堆放后没有扰动砷渣(场)、扰动并已修复的砷渣场及扰动正在修复砷渣场周边水环境进行分析,发现长期堆放后没有被扰动的砷渣(场)周边地表水体达到《地表水环境质量标准》(GB3838—2002)Ⅲ类标准;扰动正在修复和已修复的砷渣(场)周边地表水环境恢复较快,地下水恢复较慢,恢复周期较长。

According to the analysis on the peripheral water environment of arsenic slag dumps,as a product of white arsenic smelting,which were not disturbed after stockpiling,and those which were disturbed and re-stored,and those which were being restored after disturbance,it is suggested that the peripheral surface wa-ters of the arsenic slag dumps after stockpiled for a long time reached the standards of Type III in Environ-mental Quality Standards for Surface Water (GB3838-2002).The peripheral water environment of arsenic slag dumps which were disturbed during or after restoration recovered shortly while the ground water recov-ered slowly with longer recovery periods.
