摘要从2014年7月1日开始国家环保部将公布新的大气污染物排放标准(GB13223-2011)对于现有火力发电厂。新的排放标准对火电厂的主要排放污染物(二氧化硫,烟尘,氮氧化物等)提出了更加严格的排放要求。火电厂作为国企,不仅仅是大气污染的主要来源,也是大气环境治理的成员。环境压力和社会责任都以日剧增。本文通过对其产生的氮氧化物,烟尘和SO2的排放量进行分析,并且阐述它们会对周围环境产生一系列的污染问题。了解到这些污染物对人们的身体、周围环境以及其附近建筑物都有直接或者间接的威胁。与此同时,它们也会使人们患慢性咽炎、支气管哮喘等病的可能性大大增加,尤其是对年龄小的和年龄大的人群。其中氮氧化物和二氧化硫是形成酸雨的主要原因,而烟尘会对人类的呼吸系统造成较大的伤害。最后通过提出合理的措施来降低这些污染物的排放量,达到减少对周围的环境和周围生活的生物的伤害。例如针对烟尘的排放有各类除尘器,针对二氧化硫的排放有各种脱硫技术,针对氮氧化物的排放有燃烧脱氮和烟气脱硝。54627
Abstract Starting in July 1, 2014, the State Environmental Protection Department will announce the new emission standards for air pollutants (GB13223-2011) for existing fossil fuel power plants.New emission standards for thermal power plant emissions of major pollutants (sulfur dioxide, soot, nitrogen oxides, etc.) put forward more stringent emissions requirements.Thermal power plant as a state controlled enterprise, not only is the main source of atmospheric pollution, but also a member of the atmospheric environment management.Environmental pressures and social responsibility are increasing.Based on Zhejiang Yueqing power plant nitrogen oxides, soot, sulfur dioxide emissions analysis, and their emissions will cause a series of environmental pollution problems.It is known that these pollutants have direct and potential hazards to human health, ecosystem and building facilities.Can make children's immune function decline, chronic pharyngitis, bronchial asthma incidence increased, while the elderly eye, respiratory rate increased.Nitrogen oxides and sulfur dioxide are the main reasons for the formation of acid rain, and the smoke will cause greater damage to the human respiratory system.The smoke and dust can cause greater damage to the human respiratory system.Finally, put forward reasonable measures to reduce emissions of these pollutants, reduce to the surrounding environment and the surrounding life damage.For example, there are various types of dust for the discharge of dust, sulfur dioxide emissions have a variety of desulfurization technology, nitrogen oxides emissions of NOx and flue gas denitrification.
