Abstract: A total of 2589 industrial sources were investigated in the second national pollution source census in Cao County, and the distribution, quantity and emission of industrial waste gas pollution sources were found out. According to enterprise production raw materials, the circumstance such as emissions of sulfur dioxide,nitrogen oxides and volatile organic compounds and particulate matter were analyzed. The results showed that the emissions of waste gas from the wood processing and wood, bamboo, cane, palm, grass products contained more sulfur dioxide, nitrogen oxides and particulate matter. Paper-making and paper products emitted more organic waste gas. The removal efficiency of nitrogen oxides was the lowest in the process of pollutant treatment.Therefore, the countermeasures and strategies of regional waste gas treatment were proposed, which provided a scientific basis for regional air pollutants treatment.
