基于可凝结颗粒物采样的乌鲁木齐典型污染源烟气水溶性离子排放特征研究OA

In order to analyze the emission characteristics of water-soluble ions in flue gas from typical stationary pollution sources in Urumqi,a CPM sampling method was adopted to determine and analyze water-soluble ions in filterable particulate matter(FPM)and CPM from flue gas of several typical local pollution sources.The results demonstrated that the distribution and chemical composition of water-soluble ions varied significantly among different types of flue gas,and there were characteristic ions in some flue gases.The total concentration of water-soluble ions in CPM exceeded that in FPM,highlighting its dominant contribution to ion emissions,which indicates that CPM should be the key focus of future in-depth emission reduction and control.This study provides a scientific basis and technical support for regional air pollutant source apportionment and the precise control of stationary pollution sources.
