河流环境中硝基苯的归趋模型研究

河流发生硝基苯污染事件发生后，将对沿岸的生产生活产生较大影响。为了分析污染物在下游河流中的时空分布情况，以北方某江段突发硝基苯污染事件为研究对象，基于河流水质数学模型理论及苯污染物迁移转化规律，建立了一维水流和硝基苯迁移转化模型。所建模型涉及硝基苯光降解、挥发、吸附与沉积等多方面，系统地考虑了硝基苯在水、气和固三相间的转化。利用所建立的模型对突发污染事件的河段进行了水质模拟分析，揭示了事故发生地河流中硝基苯的时空分布情况，模拟结果与实测结果较为吻合，可为有关部门处理突发污染事故提供决策依据。

Study of fate model of nitrobenzene in rivers

In order to analyze the distribution condition of pollutant,an emergent water pollution accident of nitrobenzene of a river reach in northern China is taken as a research object,and based on river quality model and nitrobenzene migration and transformation theory,a 1D hydrodynamic and nitrobenzene transformation model is developed,which considers the transformation of nitrobenzene among water,air and solid and can reflect photodegradation,volatilization,absorption and silting of nitrobenzene.The model was a...
