太原市高架源二氧化硫排放分布特性分析

Analysis on the Distribution Characteristics of Sulfur Dioxide Discharged by Elevated Pollution Sources in Taiyuan

选取2017年7月—2018年6月太原市所有高架源排口的二氧化硫在线监测数据,分析二氧化硫排放浓度和排放量全年变化规律,同时利用GIS作图得出太原市二氧化硫污染分布格局。结果表明:太原市6大行业采取了多种削减二氧化硫排放的措施,二氧化硫浓度大幅减小;各行业二氧化硫排放量由大到小排序依次为水泥、钢铁、火电、焦化、冬季采暖、常年运行锅炉;太原市二氧化硫污染分布格局全年变化较小,太原城区东北部、清徐和古交是太原市二氧化硫排放的重点区域。

This paper analyzes the change rule of sulfur dioxide concentration and amount from July 2017 to June 2018,meanwhile obtains the distribution characteristics of sulfur dioxide pollution in Taiyuan by GIS map,selecting the on-line monitoring data of sulfur dioxide from elevated pollution sources . The results show:the six major industries had adopted various measures to reduce sulfur dioxide pollution,and the concentration of sulfur dioxide has been greatly reduced;the sulfur dioxide discharge amount were ranked from large to small in order:cement industry,steel industry,thermal power industry,coking industry,winter heating industry,and running boilers industry all year round;the distribution of sulfur dioxide pollution in Taiyuan had little change throughout the year,the northeast part of urban area,Qingxu and Gujiao were the key areas for sulfur dioxide pollution in Taiyuan .
