摘要《火电厂大气污染物排放标准》（GB13223-2011）实施后对现有的火电厂减排是一个巨大的挑战。为了解新标准实施后徐州市火电厂大气污染物的达标情况，本文选取徐州市7家国家重点控制的污染源火电企业为研究对象，共设立16个监测站点，以火电厂产生的主要大气污染物SO2，NO2，烟尘及新标准中的汞为评价因子，通过2015年手工监测数据与全年在线监测数据的对比分析，发现大部分监测点的污染物排放都能稳定达标，结果表明徐州市国控火电企业采用布袋除尘和静电除尘工艺均能稳定达标，采用湿法脱硫工艺比半干法脱硫工艺更能稳定达标，采用SNCR脱硝技术比低氮燃烧法更易达标，但是徐州市目前的脱硝技术还存在一定的升级空间。因此改进大气污染物处理设施，降低大气污染物排放浓度成为火电厂清洁生产和稳定达标的必然选择。67290

The Analysis of Standard Reach of Atmospheric Pollutants Emission in Xuzhou City State-controlled Thermal Power Plants

Abstract

The emission standard of air pollutants in thermal power plant "(GB13223-2011)  is a big challenge to the air pollution control of thermal power enterprises in Xuzhou city. In order to research the standards of atmospheric pollutants of thermal power plants in Xuzhou after the implementation of new standards,This thesis selects Xuzhou City seven key state-controlled sources of pollution of thermal power enterprises as the research object, setting up 16 monitoring sites, generating the main atmospheric pollutants of thermal power plants (sulfur dioxide, nitrogen dioxide, smoke dust and mercury) as the evaluation factors, by comparison analysis between 2015 manual monitoring data and annual online monitoring data, It is found that the most of the monitoring of the pollutant discharge standards and stability. The results show that in Xuzhou City control of thermal power enterprises using bag filter and electrostatic precipitator technology can stable up to standard, the wet desulfurization process than semi dry desulfurization process more stable and standard, adopting the SCR denitration technology than low nitrogen combustion method is more easily achieved, but in Xuzhou the denitration technology still exist certain space to upgrade. Therefore, it is necessary to improve the installations of pollutants treatment and decrease the emission concentration of atmospheric pollutants, to achieve clean production and standard meeting of thermal power plants.
