摘要
冶炼厂利用冶炼废气回收SO2生产硫酸,生产过程中排放的SO2危害作业人员健康。SO2污染状况调查的目的是为了控制工作场所的空气质量,提醒各类职业人君密切注意职业卫生安全作业,在作业过程中加强防范意识。本调查采用气泡吸收法采样后,用二氧化硫甲醛缓冲溶液-盐酸副玫瑰苯胺分光光度法测定样品。结果表明该冶炼厂中工作场所某些岗位的SO2超标,应进行整改,加强工作场所通风和改进生产装置。
The SO2 from sulfuric acid production process using the waste gas of metallurgy plant is harmful to workers health. The aim of investigating SO2 pollution state is to remind professional groups to keep watch out of safe operation and professional sanitation, and to enhance protection consciousness. The samples were collected by bubble absorption method in this investigation, and the samples were determined by formaldehyde absorbing - pararosaniline spectrophotometry method. The results showed that the SO2 content at some posts of the plant was over national standard, it should be rectified and improved, the ventilation of workplace should be enhanced and the production devices should be improved.
