摘　　要：本论文主要探讨的是固定污染源中二氧化硫监测的方法,目前在国家生态环境部网站公布的二氧化硫监测的方法有碘量法、定电位电解法、非分散红外吸收法。2015年10月13日,山东省地方标准出台了《固定污染源废气二氧化硫的测定紫外吸收法》(DB37/T2705-2015);2019年10月24日,生态环境部发布了《固定污染源烟气(二氧化硫和氮氧化物)便携式紫外吸收法测量仪器技术要求及监测方法》(HJ1045-2019),本文将对紫外吸收法测量二氧化硫一并讨论。通过探讨,我们将分析各种方法的原理和优缺点,从而使我们监测二氧化硫的方法更加科学、合理,适应现场监测的要求。This paper mainly discusses the monitoring methods of sulfur dioxide in stationary pollution sources.The monitoring methods of sulfur dioxide currently published on the official website of Ministry of Ecological Environment include iodometric method,constant potential electrolysis method and non-dispersive infrared absorption method.On October 13,2015,Shandong Province has published the"Ultraviolet Absorption Method for the Determination of Sulfur Dioxide in Waste Gas from Stationary Pollution Sources"(DB37/T2705-2015);On October 24,2019,Ministry of Ecological Environment published"(Sulfur Dioxide and Nitrogen Oxides)Technical Requirements and Monitoring Methods for Portable Ultraviolet Absorption Gauge"(HJ1045-2019).The measurement of sulfur dioxide using ultravioletabsorption method will be discussed in this paper.Through discussion,we will analyze the principles,advantages and disadvantages of various methods,so that our method of monitoring sulfur dioxide is more scientific and reasonable,and meets the requirements of on-site monitoring.
