摘　　要：针对某1 000 MW燃煤机组超低排放示范工程,开展污染物现场测试及排放特性分析研究。对关键常规污染物、非常规污染物的脱除效率进行实测,并分析得到其排放特征及排放绩效。测试结果表明,通过燃煤电站超低排放技术改造可显著降低大气污染物排放水平,各污染物控制单元对常规污染物实现高效控制,非常规污染物通过现有污染物控制单元实现高效协同脱除。以测试的1号机组为例,测试期间,总排放口处烟尘、SO2、NOx平均排放浓度分别为1.1、13.38、31.75 mg/m3,Hg及其化合物、PM2.5、液滴及SO3平均排放浓度分别为1.65μg/m3、0.29、6.95、2.92 mg/m3。SO2、NOx排放绩效分别为0.039 7、0.094 2(k W·h),污染物排放远优于国际平均排放水平。100%负荷条件下,SCR、ESP、WFGD、WESP分别实现SO3的脱除效率为-27.1%、21.8%、76.8%及73.9%,WFGD对Hg的协同脱除效率达到80%。Different pollutants emissions were monitored in an ultra-low pollutants emission coal-fired power plant. The pollutants removal efficiencies and emission characteristics can be calculated based on the monitoring results. Pollutants emission characteristics and performance were obtained. The results show that pollutants emission decreases obviously with the application of ultra-low emission technology in power plant Common pollutants and other pollutants is effective controlled through the pollution control equipment and coordinated control. The average concentrations of PM, SO2 and NOx are 1.08, 13.38, 31.75 mg/m3 respectively, and the concentrations of mercury, PM2.5, droplet and SO3 are 1.65 μg/m3, 0.94, 6.95, 2.92mg/m3. The emission achievements of SO2 and NOx were 0.0397 and 0.0942g/（kW·h）respectively. The sulfur trioxide removal efficiencies of SCR, ESP, WFGD and WESP are -27.1%, 21.8%, 76.8% and 73.9% respectively, and the mercury removal efficiency by WFGD is about 80%.
