摘　　要：通过分析大型体育场馆挥发性污染物恒定挥发速率和动态挥发速率,在模拟环境仓中,对挥发性污染物开展源测试,源测试的目的是明确挥发性污染物释放速率受时间影响的变化规律,在此基础上,建立大型体育场馆挥发性污染物排放规律动态监测模型。通过该模型监测宜昌市大型体育场馆挥发性污染物排放规律为体育场馆装修完3年后,甲醛超标率为7.66%,苯系物超标率达到0.00%,时间越长,体育场馆挥发性污染物浓度越低;温度是10℃和30℃时,体育场馆挥发性污染物浓度分别是0.05 mg/m^3和0.60 mg/m^3,温度越高,挥发性污染物浓度越大;低温度低湿度环境使挥发性污染物排放量增加。证明该监测模型效果好,准确性高。After the decoration of large sports venues,volatile pollutants cause different degrees of damage to the human body.Therefore,a model is designed to dynamically monitor the emission law of volatile pollutants in large sports venues.The study analyzed constant volatilization rate and dynamic evaporation rate in large sports venues,in the simulation environment storehouse,the volatile pollutants in source test,source test is clear the purpose of volatile pollutants release rate affected by the time the change rule.On this basis,the establishment of large-scale sports venues volatile pollutants discharge rule of dynamic monitoring model.The model was used to monitor the emission law of volatile pollutants in large sports venues in Yichang:three years after the decoration of sports venues,the exceeded formaldehyde rate was 7.66%,and the exceeded benzene rate reached 0.00%.The longer the time,the lower the concentration of volatile pollutants in sports venues.When the temperature is 10℃and 30℃,the concentration of volatile pollutants in the stadium is 0.05 mg/m^3 and 0.60 mg/m^3 respectively.The higher the temperature,the greater the concentration of volatile pollutants.Low temperature and humidity increase the emission of volatile pollutants.
