On May 18, Xiling Gorge of the Yangtze River after rain, with high gorges and flat lakes, green mountains and green waters, and swirling clouds, formed a beautiful natural ecological beauty. Mercury pollution is becoming a serious global pollution, especially coal-fired power plants account for a large proportion. In this paper, the mercury pollution situation at that time and the monitoring requirements of various governments are sorted out, and the calibrators, catalytic conversion methods, measurement methods, key points and points for attention in the system planning of the mercury continuous emission monitoring system CEMS are introduced. Polaris Atmosphere News: Recently, Henan Province printed and distributed the work plan for Henan Province to promote industrial restructuring and win the battle against pollution. According to the plan, by the end of 2019, the province's steel, aluminum carbon, cement, glass, coking and electrolytic aluminum industries will strive to complete ultra-low emission transformation.
