摘要
通过对车间区、办公区、住宿区和厂外区4个区域室内空气中SO2、NO2、甲醛、PM2.5、PM10浓度指标进行分析,并与室内空气质量标准(GB/T 18883-2002)各污染物标准值进行对比,结果表明,SO2、PM2.5、PM10浓度随季节变化较大,且在7月车间区SO2、PM2.5、PM10浓度分别为0.201 mg/m3、0.058 mg/m3、0.198 mg/m3,办公区SO2、PM2.5、PM10浓度分别为0.532 mg/m3、0.049 mg/m3、0.178 mg/m3,都处于较高浓度水平,NO2、甲醛浓度在4个区域中最大浓度分别为0.232 mg/m3、0.044 1 mg/m3,都未超过国家标准。
The concentration index of SO2,NO2,formaldehyde,PM2.5 and PM10 of the workshop area,office area,residential area and outside the factory area four regional is analyzed. Compared with the indoor air quality standard(GB/T 18883-2002) each pollutant standard,the results showed that SO2,PM2.5 and PM10 concentration changed greatly with the seasons,and in workshop area,SO2,PM2.5 and PM10 concentration were 0.201 mg/m3,0.058 mg/m3,0.198 mg/m3 respectively in July.In the office area,the concentration of SO2,PM2.5 and PM10 were 0.532 mg/m3,0.049 mg/m3,0.178 mg/m3 respectively,which were all at a relatively high level. The maximum concentration of NO2 and formaldehyde in the four areas is 0.232 mg/m3 and 0.044 1 mg/m3 respectively,which do not exceed the national standard.
