摘要
根据燃煤电厂湿法脱硫出口污染物排放浓度及其排放绩效,分析了超低排放湿法脱硫的治霾效果,阐明了湿法脱硫有利于减少SO2、颗粒物、SO3的排放量,这些污染物都是形成雾霾的前体物,表明超低排放湿法脱硫对雾霾治理有积极的贡献。同时,烟气超低排放具有协同治理有色烟羽的能力,对于有色烟羽治理应采取因地制宜的策略。煤电行业广泛开展烟气超低排放改造后,大气污染物排放量持续减少,空气环境质量逐年改善,湿法脱硫、烟气超低排放功不可没。
According to the emission concentration and emission performance of pollutants from wet flue gas desulfurization(WFGD)of coal-fired power plants.The haze control effects of ultra-low emission WFGD were analyzed.Emissions of SO2,particulate matter and SO3 are reduced by WFGD.These pollutants are precursors of haze.It shows that it has positive contribution to haze control by ultra-low emission WFGD.At the same time,the colored plume has been ability to control cooperatively by ultra-low emission.The colored plume should be controlled according to local conditions.After the extensive transformation of ultra-low emission in electricity industry,emissions of air pollutants have been continuously reduced.The quality of air environment has improved year after year.The contribution is due to WFGD and ultra-low emissions.
