摘要
通过对宝钢厂区大气环境主要污染物监测数据的整理,综合分析了宝钢厂区大气环境中二氧化硫、氮氧化物、可吸入颗粒物(PM10)和一氧化碳四种主要污染物的平均浓度随季节的变化趋势以及厂区内降尘的污染状况,并对2008年大气环境质量状况进行了综合评价。分析对比结果表明宝钢内大气主要污染因子是PM10和SO2,从监测资料看,2008年厂区降尘量比2007年有了明显下降,SO2和NOx的达标率均呈现上升趋势,可见宝钢在粉尘和脱硫脱氮治理方面取得了显著效果,污染程度明显下降。
Through sorting out the monitoring data of the main atmospheric pollutants in Baosteel plant area,the average concentration and the variation trend of SO2,NOx,PM10and four main CO pollutants varying with the seasons,and the status of natural fall dust were analyzed.The general situation of the atmospheric environmental quality in Baosteel plant area in 2008 was estimated.The analysis shows that the major pollutant factors in Baosteel are PM10 and SO2.According to the monitoring data,the amount of natural fall dust was reducing and the eligible rate of SO2 and NOx was increasing in 2008, compared with the data in 2007. It indicates that the degree of pollution is decreasing apparently and treatment measures for reducing dust, desulfurization and denitrogenation have achieved remarkable effectiveness.
