An explosion in a petrochemical plant in Jilin in the northeast of China on 13 November 2005 was responsible for the discharge of large quantities of benzene and nitrobenzene into Songhua River. This endangered the water supply of Harbin city and influenced the daily life for millions of people. The dispersion-advection equation was solved analytically and numerically and used to simulate the concentration of benzene and nitrobenzene in the Songhua River after the accident. Both solutions gave practically identical results. The main elimination process for both compounds was volatilization. The model results are quite close to the results obtained by measurements at monitoring stations. Arrival time of the pollutant wave, peak concentrations and end of the pollutant wave at Harbin and along the river were predicted successfully. The peak concentrations of nitrobenzene at Harbin were more than 30 times above the permissible limits for drinking water.
2005年11月13日，中国东北部吉林省的一家石化厂发生爆炸，导致大量苯和硝基苯排入松花江。这危及了哈尔滨市的供水，并影响了数百万人的日常生活。对扩散-平流方程进行了解析求解和数值求解，并用于模拟事故后松花江中苯和硝基苯的浓度。两种解法得出的结果几乎相同。两种化合物的主要消除过程是挥发。模型结果与监测站的测量结果非常接近。成功预测了污染物波的到达时间、峰值浓度以及在哈尔滨和沿江的污染物波结束时间。哈尔滨硝基苯的峰值浓度超过饮用水允许限值30多倍。
