| 目的 分析以大气沉降为主的土壤影响预测及评价。方法 采用AERMOD模型进行有机废气干沉降量、湿沉降量、总沉降量的计算。结果 该区域内甲苯干沉降量占总沉降量比在97%~99%之间，湿沉降对总沉降量的贡献值很小，甲苯在该区域干沉降过程沉降速度范围为0.0003~0.0033 m/s，平均沉降速度为0.0016 m/s。结论 以甲苯为代表的有机废气大气沉降计算主要以干沉降为主，干沉降速度具有明显的日变化特征，一般在中午前后出现最大值，大气沉降对周围土壤环境影响较小。 |

| The work aims to analyze the prediction and evaluation method of soil impact mainly based on atmospheric deposition. The dry deposition, wet deposition and total settlement of organic waste gas were calculated by AERMOD model. The dry deposition of toluene accounted for 97% to 99% of the total settlement in this area, and the contribution value of wet deposition to the total settlement was very small. The settlement speed range of toluene in the dry deposition process of this area was 0.0003~0.0033 m/s and the average settlement speed was 0.0016 m/s. The calculation of atmospheric deposition of organic waste gas represented by toluene is mainly based on dry deposition. The dry deposition rate has obvious diurnal variation characteristics, and generally the maximum value appears around noon. The atmospheric deposition has little impact on the surrounding soil environment. |
