Datong coal was being as main coal, the Shandong coal somewhere was used as auxiliary coal, columnar activated carbon with silver was prepared by doping method. Meanwhile, regular performance indicators of the samples were measured, its research concentrated on the antimicrobial action on E. coli and the silver erosion performance. The results showed that silver load of the samples increased with the concentration of AgNO3 solution increased, and the doping did not affect the pore development of activated carbon. In terms of the sample that silver content was 0.517%, the number of average recovery living bacteria was killed from the concentration of 3.3×105 CFU/mL, less than 100 CFU/mL after 24 h, the antibacterial rate was greater than 99%. This fully showed that the activated carbon with silver were prepared had the stronger antibacterial performance. Simultaneously, the sample had favorable resistance to water erosion, the silver loss was only 2.13% in 480 h for surging.
