摘　　要：通过机制木炭与碳酸钙对锑矿废水的处理效果,找出对锑矿井废水处理最经济有效的方法。对典型锑矿污染地区矿井水进行了采样,利用氢化物原子荧光光谱仪测定其锑、砷、汞含量,并与国家排放标准进行了对比。利用机制木炭、碳酸钙两种方法分别对锑矿井废水进行处理,并测定其锑、砷、汞含量。结果显示:机制木炭的吸附过滤作用可将锑矿井废水中含锑量从5 557.44—5 714.01μg/L降低至40.11μg/L;粉状碳酸钙的吸附作用可将废水含锑量降至最低83.97μg/L(P<0.05),且碳酸钙对酸度较高(p H=3)的矿井废水有良好的调节效果(p H达7.8左右)。实验证实利用机制木炭和碳酸钙的吸附技术可以实现对锑矿井废水中锑、砷、汞等重金属的有效处理,使其达到国家排放标准。Through the treatment effect of mechanism charcoal and calcium carbonate to antimony wastewater,find out the most economic and effective method that treats of antimony wastewater. Methods： Took samples of the typical antimony mine water pollution area,and the content of antimony,arsenic and mercury were tested by hydride—atomic fluorescence spectrometer,which compared with the national discharge standard. To treat the antimony wastewater by the two methods of mechanism charcoal and calcium carbonate,and determine the content of antimony,arsenic and mercury. Results： the adsorption filtration functions of mechanism charcoal made the antimony content in the waste of antimony wastewater from 557.44—714.01μg / L reduced to 40.11μg / L; the adsorption filtration functions of calcium carbonate made the antimony content in the waste of antimony wastewater reduced to 83.97μg / L（ P〈0.05）,and calcium carbonate of high acidity（ p H = 3） mine wastewater had the very good adjustment effect（ p H 7. 8）. Conclusion： These experiments confirmed that the adsorption filtration functions of mechanism charcoal and calcium carbonate could treat the content of antimony,arsenic and mercury in antimony mine wastewater,making it meet the national discharge standard.
