| 摘 要： | 活性炭吸附二恶英技术是减少烟气二恶英排放的有效方法,在实际应用中90%以上的二恶英会被吸附于活性炭上,然而附集了二恶英的活性炭若不进行无害化处理会造成二次污染,低温脱氯法被认为是二恶英无害化处理的首选。以氯苯作为二恶英的模拟物,通过小试研究,探讨活性炭对氯苯的吸附量,以及温度对氯苯降解效率(DE)的影响,并寻找出最适合条件,开展中试工程研究。小试结果表明:在100℃下每克活性炭可吸附139 mg的氯苯,于降解氯苯部分发现,活性炭吸附的氯苯在高温的氮气气氛下会发生降解。当温度为340℃,反应4 h,DE可达62%,在400℃反应4 h后DE可达94%。采用活性炭对二恶英降解开展示范工程研究,中试采用连续式进料设备,处理能力达20 t/h,停留时间为2 h,在430℃反应后对活性炭中的二恶英降解率可达97%以上,表明二恶英有效分解,中试工程的成功为我国钢铁行业二恶英排放的控制提供技术支持。

| Abstract: | The emission concentration of pollutants from port greatly affects the ambient air quality.This paper evaluated the impact on air quality during the port paralysis,which took place in Hong Kong international container in March 28th,2013.Firstly,the correlation analysis between pollutants determined that pollutants influenced by the strike mainly were NO2,NOx,O3,SO2.Secondly,based on the pollutants concentration before,during and after the strike,the pollutant emission didn't have a certain degree of reduction during the strike through horizontal comparison.Thirdly,excluding the impact brought by the seasons,the longitudinal comparison assessed the air quality during the strike in different years but the same phase.Finally,taking NO2 as an example,establishing forecasting model predicted the concentration of NO2 during the strike.The differences between the actual value and predicted value affected the trend of NO2.This study mainly emphasized the influence of port air quality on the environment,offered decision support for the government to implement the policy to a certain extent,and focused on the impact of interactions between pollutants into the environment. |
