The heavy metals including Pb, Cd, Cr, As and Mn emission characteristics of coal-fired power plant boilers, industrial boilers, lead and zinc smelters, cement kilns, and steel industries were studied in this paper. The removing effects of heavy metals by pollution control technology were analyzed. ICP-AES method was used to measure the contents of heavy metals in solid samples. In addition, M-29, the U.S. EPA isokinetic sampling method was used to sample heavy metals in the flue gas, and the sampled heavy metals were tested by ICP-AES-hydride generator system. For coal-fired boilers, heavy metal contents in descending order were Mn, Pb and Cd in the tested coal. The heavy metals’ emission concentrations of coal-fired industrial boilers were much higher than the heavy metals’ emission concentrations of power plants. For the lead and zinc smelters, Pb and its compounds in flue gas after cleaning can meet the emission standards. The heavy metal contents in the cement raw materials in descending order were Pb, Cr and Cd. For the sintering mixture, the heavy metal contents in descending order were Pb, Cr and Cd as well. The removal effects of heavy metals by existing pollutant control technologies in the various typical industries were also tested and analyzed in the paper. The research did in the paper made a scientific basis for controlling heavy metal emissions from typical industries.
