汽车修理养护企业挥发性有机物排放控制标准探讨

通过对汽车修理养护企业喷烤漆废气排放现状进行调查分析,指出中国目前适用于控制汽车修理养护企业废气排放的标准《大气污染物综合排放标准》(GB 16297-1996)在实际运用中存在的问题。依据《制定地方大气污染物排放标准的技术方法》(GB/T 3840-1991)《大气污染物综合排放标准详解》《工作场所有害因素职业接触限值化学有害因素》(GBZ 2.1-2007)《工业企业设计卫生标准》(TJ 36-1979)、美国环保局多介质环境模型等,用不同方法计算汽车修理养护企业排放的废气中几种挥发性有机物的排放浓度和排放速率限值,并对监测结果进行评价分析,提出编制汽车修理养护企业废气排放控制标准的建议。

Discussion on Volatile Organic Substance Emission Control Standard of Vehicle Repair and Maintenance Company

The problem was discussed on ＂ Integrated emission standards of air pollutants＂ （GB 16297 - 1996） in practical application, used in China to control exhaust gas emission of vehicle repair and maintenance company. In this standard, the controlled environmental factor didnt contain the main pollution agents of exhaust gas emission, without controlling the emission of Total Volatile Organic Compounds （TVOC） which would affect atmospheric environment quality. Based on ＂ Technical methods for making local emission standards of air pollu- tants＂ （ GB/T 3840 - 1991 ） , ＂ Occupational Exposure Limit for Hazardous Agents in the Workplace＂ （ GBZ 2. 1 -2007 ）, ＂ Hygienic Standards for the Design of Industrial Enterprises＂ （TJ 36 - 1979）, and USEPA muhilay- ered medium environmental model, the study calculated the limit value of emission concentration and emission rate of several volatile organic substances of exhaust gas discharged by vehicle repair and maintenance company with different methods. The data was analyzed to make suggestion on drafting standard for exhaust gas emission of vehicle repair and maintenance company.
