摘　　要：以购物商场等公共场所的环境空气为监测和治理对象,针对喷雾抑尘后空气的粉尘浓度在线监测结果易受高湿度环境影响等问题,利用统计模型法的经验公式对光散射法监测结果进行修正,以克服湿度对粉尘浓度监测准确性的影响。运用国际上规定的粉尘监测的基准方法（滤膜称重法）,对湿度修正光散射法进行平行对比监测试验,试验结果表明修正后的光散射法和滤膜称重法监测结果具有高度一致性。在此研究的基础上,将基于湿度修正的光散射法的粉尘浓度在线监测技术实际应用于某购物商场环境的空气在线监测与治理,取得了良好效果。The purpose of this article is to monitor and improve the air in public places,e.g.,the shopping mall.At present,the result of field dust concentration monitoring in the air after spraying is easily affected by the high humidity environment.In order to eliminate the influence of moisture on the accuracy of dust concentration monitoring,the empirical formula of the statistical model method is utilized to correct the light scattering method.In addition,the parallel comparison monitoring test is performed between the corrected light scattering method and the international dust monitoring method（i.e.,the membrane weighing method）.The experimental results show that these two methods have the high consistency.Based on this study,the dust concentration field monitoring method has been applied to the practical monitoring and environmental treatment of ambient air in a shopping mall,which has obtained excellent results.
