【摘要】 对鱼新街国控点空气质量自动监测站八方位污染源进行了排查,国控点监测数据显示:冬春季节PM_2.5、PM₁₀、SO₂小时平均值曲线波动趋势平缓,NO_x小时平均值曲线呈W形发展;从小时峰值点看:PM_2.5、PM₁₀、NO_x夜间比较集中,SO₂则是午间比较集中;污染源调查结果表明:国控点周边污染源负荷较大,有珞璜电厂总装机2 640MW发电机组、玖龙纸业,以及4个年产能共计930万t的水泥企业等大型污染源;其中珞璜电厂小时浓度与自动监测站小时浓度之间有较强的正相关,高架源仍然是重点污染源;重载汽车尾气、餐饮油烟、夜市烧烤也是影响国控点监测数据的重要原因。更多还原

【Abstract】 The source of the air quality automatic monitoring station of the national controlled Yuxinjie Point was checked. The national controlled point Monitoring data show that Winter and Spring season PM_2.5, PM₁₀, SO₂ hour average curve fluctuation trend is flat, which of NO_x is W type; Viewed from the peak point of the hour: PM_2.5、PM₁₀、NO_x peak point centralize in night time, and which of SO₂ is centralize in midday. Pollution source survey results show that Large load of pollution sources around national control point, there are Luohuang Power Plant with 2640 MW generator Unit and New Dragon paper（Chongqing）Limited and 4 cement companies with an annual production capacity of 9.3 million t. the hourly concentration is strong positive correlation between the Luohuang Power plant and the automatic monitoring station. Elevated sources are still a key source of pollution. Heavy duty car exhaust, catering fumes, Night market barbecue is also an important reason to influence the monitoring data of national control points.更多还原
