气象因素的城市固定污染源中氟化物含量监测点设定研究

Selection of Monitoring Points for Fluoride Content in Urban Fixed Pollution Sources Considering Meteorological Factors

城市固定污染源中氟化物监测点的合理设定,没有考虑气象因素的影响。为此,提出考虑气象因素的城市固定污染源中氟化物含量监测点设定方法。确定氟化物逸散时风向以及污染系数对污染空间的影响;结合低空气象特征,确定监测点布设数量以及监测点布设原则,完成监测点的设置;根据设置结果对污染源位置的氟化物含量进行监测,从而实时获取城市固定污染源的氟化物浓度含量。实验结果表明,非生长季节,污染源位置10个监测点中,仅有两个监测点未有效警告;下风向污染较重,越靠近污染源的位置越容易发出告警,符合设定要求。

The current selection of fluoride monitoring points in urban stationary pollution sources does not consider the influence of meteorological factors.Therefore,a method for setting monitoring points for fluoride content in urban fixed pollution sources considering meteorological factors is proposed.The study determined the impact of wind direction and pollution coefficient on the polluted space when fluoride escapes and determined the number and principles of monitoring point layout based on low altitude meteorological characteristics.It monitored the fluoride content at the pollution source location based on the setting results in order to obtain real-time fluoride concentration content of fixed pollution sources in the city.The experimental results show that out of the 10 monitoring points at the pollution source location during non growing seasons,only two monitoring points did not provide effective warnings.The downwind direction is heavily polluted,and the closer it is to the pollution source,the easier it is to issue an alarm,which meets the set requirements..
