Abstract:
On the basis of the related statistical data,the distribution status and industry,type and spatial characteristics of major air pollutants( SO
2,NO
X and particulates) from the industrial furnaces and kilns of Anhui Province in 2017 were analyzed. The results showed that SO
2,NO
X and particulates emission of Huainan,Fuyang,Tongling,Wuhu,Xuancheng,Ma'anshan and Chuzhou City accounted for 68. 8%,68. 0% and 74. 1% of total emission of all industrial furnaces and kilns from the perspective of spatial distribution. From the perspective of industry distribution,SO
2,NO
X and particulates emission of non-metallic mineral products industry,non-ferrous metals smelting and pressing industry,petroleum,coal and other fuel processing industries,chemical raw materials and chemical manufacturing industry accounted for 95. 3%,96. 1% and 97. 3% of total emission of all industrial furnaces and kilns. From the perspective of type distribution,SO
2,NO
X and particulates emission of sintering kiln,cement clinker kiln,smelting furnace,melting furnace and calcining furnace accounted for 82. 2%,85. 3% and 92. 6% of total emission of all industrial furnaces and kilns. Generally,the denitrification efficiency of industrial furnaces and kilns was low. Therefore,future pollution control and environmental management measures should be strengthened on exhaust gas of industrial furnaces and kilns in key areas,industries and types.
