硝基苯在冰-水环境中的迁移分配研究

Study on migration and distribution of nitrobenzene in ice-water environment

本文通过松花江哈尔滨江段实际水样冰冻试验,研究了自然冰冻过程中硝基苯在松花江冰-水环境中的迁移分配规律,同时对松花江四方台断面和大顶子山断面水中硝基苯含量进行了监测。文中推算了硝基苯污染团过境哈尔滨下游江段时冻结在冰体中硝基苯的含量,分析预测了春季冰体融化过程硝基苯污染物的释放对松花江水质和江居民取水的影响。同时,也为进一步研究硝基苯在冰-水环境中的迁移规律及其转化机理提供了可借鉴的参考依据。

In this paper,the migration and distribution of nitrobenzene in the ice-water environment of Songhuajiang River during the natural freezing process were studied based on the freezing test of water samples in Harbin section of Songhuajiang River.This study not only calculates the content of nitrobenzene frozen in the ice body when the nitrobenzene pollution group transits the lower reaches of Harbin,but also analyzes and predicts the impact of the release of nitrobenzene pollutants on the water quality of Songhua River and the water intake of residents along the river.At the same time,it also provides a reference basis for further research on the migration and transformation mechanism of nitrobenzene in ice-water environment.
