火电厂烟气排放对广州大气环境的影响

广州市是酸雨、可吸入颗粒物污染严重的地区之一,这与其能源结构以煤为主有关.广州发电厂以燃煤为主,其周围大气采样数据分析显示燃煤电厂可对周围大气环境造成较大影响,是酸雨前体物、可吸入颗粒物的主要排放源.酸雨破坏了生态环境,也阻碍了经济的发展;燃煤排放的烟尘细颗粒物属于可吸入颗粒物,其上附着的As、Cr等微量元素多为致癌物质和致基因毒性诱变物质,对周围居民的健康危害极大.最后, 对当前的环境保护工作及存在的问题进行了阐述.

Pay Attention to Atmospheric Environment of Guangzhou of Coal-fired Power Plants

Guangzhou is one of the cities which are seriously polluted by acid rain and PMIO, and the trend is becoming more and more serious, This is related to its major energy source being coal, Main fuel of Guangzbeu Power Plant is coal. The analysis data of air sample surrounding Guangzbeu Power Plant show that coal - fired power plants can affect their surrounding atmospheric environment seriously. Coal - fired power plants are main emission source of predecessor of acid rain and PM10. Acid rain has destroyed ecological environment and stopped economic development. On the other hand, soot particles are PMIO, As, Cr and other trace dements absorbed by soot particles are mostly carcinogenic substances and substances that can cause gene toxicant salutatory changed, being extremely endanger health of surrounding residents. Finally, this paper presents current environmental protection work and prablems.
