摘要
根据2015年、2016年J市5个空气质量自动监测点位PM 2.5相关浓度数据,对J市PM 2.5污染特征及防治策略进行了探究。结果表明,J市2016年3、11、12月PM 2.5均出现早晚高峰的高值,早高峰高值出现的时间分别为8时、9时、11时,这与逆温层的厚度关系密切,晚高峰高值出现的时间均为20时,主要的污染源贡献来自燃煤污染和机动车污染;J市5、6月份发电厂点位PM 2.5数值均出现剧烈波动的状况,考虑是监测设备运行稳定性存在问题;佳纺点位出现PM 2.5异常高点,主要来自棚户区及小散污企业污染物排放贡献,其他点位异常高点,主要来自点位附近污染物排放量瞬时增加。此外,还从监测点位布设与管理、加强部门合作、强化污染管控等方面提出了相应的防治策略。
Based on the PM 2.5 concentration data of five air quality automatic monitoring sites in J city in 2015 and 2016,the PM 2.5 pollution characteristics and control strategies of J city in 2016 were studied.The results showed that PM 2.5 in March,November and December 2016 all had the peak value in the morning and evening,and the peak value appeared at 8:00,9:00 and 11:00 respectively,which was closely related to the thickness of inversion layer.The peak value appeared at 20:00 in the evening,and the main pollution sources contributed from coal-fired pollution and motor vehicle pollution.The monitoring value of PM 2.5 in Fenghua Power Station fluctuates sharply,considering the stability of the monitoring equipment;the abnormal high point of PM 2.5 in Jiatfang Station mainly comes from the contribution of pollutant emission from shanty towns and small scattered enterprises.The abnormal high point of other points mainly comes from the instantaneous increase of pollutant emission near the point.In addition,the corresponding prevention and control strategies are put forward from the aspects of the layout and management of monitoring points,the strengthening of cooperation between departments,and the strengthening of pollution control and control.
