| 摘 要： | 为贯彻落实《大气污染防治行动计划》,环境保护部指导各地开展大气污染源排放清单编制工作,其中包括固定源PM_(10)和PM_(2.5)的排放清单.但目前国内尚无固定源PM_(10)和PM_(2.5)标准采样方法.本研究提出了适合我国固定源PM_(10)和PM_(2.5)测量的双级虚拟撞击采样方法,开发了相应的分级采样系统,并用该方法对各类固定源进行了现场测试.测试结果表明,所测试的煤粉炉电厂的烟囱入口PM_(2.5)质量浓度为(0.93±0.03)mg·m~(-3),PM_(10)质量浓度为(1.13±0.11)mg·m~(-3).所测试的垃圾焚烧电厂的烟囱排放口PM_(2.5)质量浓度为(3.3±0.65)mg·m~(-3),PM_(10)质量浓度为(6.9±0.86)mg·m~(-3).所测试的大型循环流化床发电厂的烟囱排放口PM_(2.5)质量浓度为(0.59±0.04)mg·m~(-3),PM_(10)质量浓度为(1.12±0.16)mg·m~(-3).所测试的钢铁转炉的烟囱排放口PM_(2.5)质量浓度为(0.15±0.04)mg·m~(-3),PM_(10)质量浓度为(0.43±0.15)mg·m~(-3).

| Abstract: | Recently, the Ministry of Environmental Protection of China started the development of emission inventories in fifteen Chinese cities. It includes the esmission of PM10 and PM2.5 from stationary sources. However, there is no national standard method in China for stationary source PM10 and PM2.5 sampling. In this study, a two-stage virtual impactor was developed for sampling PM10 and PM2.5 from stationary sources. Its performance was evaluated for four types of sataionary sources, i.e., coal-fired power plant, waste incineration, circulating fluid bed, and converter steelmaking. These four tested emission sources were equipped with high efficiency PM control devices. PM2.5 mass concentrations measured in the chimneys of these emission sources were (0.93±0.03), (3.3±0.65), (0.59±0.04), and (0.15±0.04) mg·m-3, respectively, while the PM10 mass concentrations were (1.13±0.11), (6.9±0.86), (1.12±0.16), and (0.43±0.15) mg·m-3, respectively. |
