摘要
以夹沟铝土矿矿渣为对象进行浸泡试验,测定浸出液的pH和C r6+,Cu2+,Zn2+,Pb2+,Cd2+等的含量,对照矿区矿坑水和地下水水质检测结果,分析充填矿渣对地下水环境的影响。浸出液各项指标测定结果均在国家标准以内,重金属离子随浸泡时间增加而缓慢上升并趋于平衡,矿渣复垦不会对地下水环境造成二次污染。
The experiments of leaching extraction of the bauxite slag after filling reclamation are conducted, and the pH and contents of Cr6＋,Cu2＋,Zn2＋,Ph2＋,Cd2＋ are measured, and the environment impacts of these factors on the ground water are investigated by comparison with the composition of the mine drainage and the underground water. It is concluded that all these measured indexes are consonant with the national standard, although the contents of these heavy metal ions are slowly increased and tended to balance ultimately. As a result of the experiment, the filling gully with bauxite slag would not cause the secondary pollution of underground water environment.
