典型恶臭有机污染自动监测技术与应用探究

对比6种主流有机硫自动监测仪的4种有机硫混标测试结果,表明80%仪器的性能指标能满足国家恶臭排放标准中厂界监测的定量要求。复杂环境适用性研究显示,有机硫化物间测定影响相对较小,高浓度标气有残留,定性受到常见挥发性有机物中个别物质干扰。优选3种检测器为FPD的仪器现场连续实测,结果表明甲硫醇、甲硫醚、二甲二硫醚和二硫化碳为石化园区的有机硫常检出物种;3种仪器的监测数据可较好地反映该石化园区空气恶臭污染特征。

Study and Application of Typical Organic Odor Pollutant Automatic Monitoring Technology

By utilizing six mainstream automatic monitors in analyzing a mixed standard gases of four organic sulfur compounds,it turned out that 80%of the tested instruments could meet the quantitative requirements of plant boundary monitoring in national emission standards for odor pollutants.Complex environment application research showed that there was less impact on the determination of these organic sulfides,high concentration of standard gases had residues,several common volatile organic compounds interfered in qualitative test.Three instruments with FID detector were optimized for continuous field monitoring in a petrochemical industry park,results showed that methyl mercaptan,dimethyl sulfide,dimethyl disulfides and carbon disulfide were common detected pollutants.The monitoring data from these three instruments reflected the odor pollution characteristics of that area.
