以苏州市为例,利用2013-2014年MODIS高分辨率大气气溶胶卫星遥感产品对国控空气监测点位布设调整方案进行评估论证,通过提取2 km和5km半径范围的PM2.5遥感观测数据,与现有国控布设点位的地面监测数据进行相关性分析后,确定卫星产品用于评估验证是可靠的;通过不同天气场下PM2.5月均值浓度分布的比较,表明调整后空气点位布设具有很好的代表性.     

高炉炉顶煤气中HCl气体脱除的试验研究

高炉炉顶煤气中HCl气体会加速TRT叶片和煤气管道腐蚀。脱除高炉炉顶煤气中HCl气体可以采用石灰石、轻烧石灰石、Na_2CO_3和KOH作为脱氯剂的活性组分,脱氯剂粒度控制为3~6 mm、脱氯剂料层厚度控制为200 mm以上并适当提高煤气温度来改善高炉煤气中HCl气体的脱除过程。     

烟气调质技术在近零排放机组中的研究与应用

为了满足燃煤机组烟尘近零排放的要求,采用烟气调质技术对电除尘器的除尘效率进行升级提效是一种有效的方式,尤其是针对燃用高比电阻煤种的燃煤电厂。从烟气调质技术的基本理论入手,研究烟气调质对除尘提效的主要影响因素,并介绍了常用的3种烟气调质技术,SO_3调质、水调质和低低温电除尘器的原理与实际应用,并论述了不同烟气调质技术取得的效果和所存在的问题。     

热解析-脉冲低温等离子体集成系统脱汞研究

热解析-脉冲低温等离子体集成处理系统是专门针对典型含汞废物安全处置而开发的,可以同时有效控制汞等多种复合气体污染物。通过检测热解炉后烟气中和等离子体反应器入口、出口气体中Hg0和Hg2+浓度,研究汞的价态转化及添加剂对脱汞效果的影响。结果表明:热解烟气中Hg2+/HgT为17%~45%,Hg0/HgT为55%~83%,热解温度主要影响汞价态分布,WMC添加量主要影响汞浓度值;加入添加剂会促进汞的脱除,但添加剂过量不利于汞的氧化;热解炉中添加50 g WMC和5 g升华硫添加剂时,反应器内Hg0氧化率和总汞损失率分别可达55%和42%。该研究可以为探索新型含汞废物处置工艺,实现含汞废物深度净化提供新思路。     

Local governance of greenhouse gas emissions from air travel

Global greenhouse gas emissions from air travel (GHG-A) are on the rise, and projections point towards a rapid growth in the coming decades. This study aims to examine how local government (cities), addresses GHG-A in their Sustainable Energy Action Plans (SEAP). To fulfil this aim, over 200 SEAPs were analysed focusing on three issues: (1) Treatment of GHG-A in local emissions inventories; (2) Policy initiatives within this domain; and (3) The cities’ perceptions of the conflicts of interests. Results showed that more than half of the cities acknowledge the challenge of GHG-A, around one third include GHG-A in their emissions inventories, and more than one quarter have initiated policy interventions. To categorise these interventions, we have added a mode ‘governing by agenda setting’ to an existing analytical framework, ‘Modes of governing’. With their authority limited to the local setting, this mode of governing is a common channel for cities to push changes at higher levels.     

A tale of ‘fat cats’ and ‘stupid activists’: contested values,governance and reflexivity in the brno railway station controversy

ABSTRACT

The article explores one of the biggest controversies over sustainability in modern Czech history, a protracted conflict over whether the Brno railway station should be re-built in a new location. By examining the language of the interaction between a ‘modernizing discourse’ and a ‘sustainability discourse’, the article highlights reflexivity as analytic enterprise that bares the governance dimension of policy conflicts. The reflexive analysis focuses on how actors justify their positions, how they distinguish themselves from their opponents and how they express trust in their own group. It reveals that both discourses are not only related to the re-location issue per se, but that they entail contested notions of legitimate knowledge and modes of governance. Since such power contest is common in sustainability controversies, the reflexive analysis suggests a novel analytical agenda for addressing policy conflicts in sustainability issues.     

燃煤锅炉烟气中SO_3的生成、危害及控制技术研究进展

SO_3是燃煤锅炉烟气中的污染物之一,会造成烟气酸露点升高、空气预热器堵塞腐蚀、"烟羽"现象等,并且降低选择性脱硝催化剂的活性和锅炉的脱汞效率,危害设备安全和大气环境。介绍了燃煤锅炉中SO_3的主要生成途径、危害、控制方法以及SO_3的控制政策。用于燃煤锅炉中SO_3的控制方法有降低燃煤硫含量,采用ROFA燃烧技术,炉内喷碱性吸收剂,炉后喷碱性吸收剂,除尘器前喷氨和使用湿式电除尘器等。
