摘　　要：以大同地区两个代表性矿区煤样为原料,通过加入特殊添加剂的方式,采用压块活性炭制备工艺,得到了性能优良的饮用水深度净化专用活性炭产品,并重点考察了活化时间对产品强度、装填密度、亚甲蓝吸附值和碘吸附值等性能的影响。结果表明:两种原料煤制得活性炭的强度最低分别为95.2%和95.6%,装填密度最低为490 g/L和498 g/L,亚甲蓝吸附值最高均为240 mg/g,碘吸附值最高值达到1100 mg/g以上,均优于现有普通活性炭。通过对比两种原料煤制得活性炭产品的孔结构,说明2号原料煤制得的活性炭产品具有更发达的孔隙结构,其比表面积和孔容分别比1号煤制得产品高出74 m2/g和0.03 mL/g。因此,2号原料煤是制备饮用水深度净化专用活性炭的合适原料煤。Prepare the excellent activated carbon for deep purification of drinking water through adding additive to two kinds of representative Datong coals using briquetting method.Investigate the influence of activation time on product strength,loading density,iodine and methylene blue adsorption.The results show that,the minimum strength of activated carbon products is 95.2 percent and 95.6 percent,the minimum loading density is 490 g/L and 498 g/L,both of the maximum methylene blue adsorption is 240 mg/g,and iodine adsorption is more than 1100 mg/g.So the performance of the product is better than that of the common activated carbon.The comparison of pore structure of the two kinds of products show that,the activated carbon preparing from No.2 raw coal has flourishing pore structure,its specific surface area and pore volume is greater than that of the product making from No.1 raw coal by 74 m2/g and 0.03 mL/g.So No.2 raw coal is the beat choice for preparing activated carbon for deep purification of drinking water.
