曹县第二次全国污染源普查工业源废气分析

Analysis of Industrial Exhaust Gas of the Second National Pollution Sources Census in Cao County

为进一步掌握区域内各类污染源的数量、行业和地区分布情况,了解主要污染物产生、排放和处理情况,曹县开展了第二次全国污染源普查,摸清了曹县工业废气污染源的分布、数量及排放情况。根据企业生产原料、废气排放量等情况对二氧化硫、氮氧化物、挥发性有机物和颗粒物进行分析,结果显示木材加工和木、竹、藤、棕、草制品业排放的废气含二氧化硫、氮氧化物、颗粒物较多,造纸和纸制品业排放的废气中有机废气较多。废气污染物治理过程氮氧化物的去除效率最低,由此提出区域废气治理的应对措施和策略,为区域大气污染物治理提供科学依据。

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.
