摘要
本文研究了松花江氮转化规律。发现低水温条件下(特别是冰封期)氨氮的实测浓度变化不符合目前广泛采用的一级动力学模式,氮扭的实测浓度主要受有机氮生成氨氮的速度和氨氮衰减速度两方面制约。应用化学动力学"连续反应"理论建立了松花江氨氮水质模型。在此基础上计算了松花江氨氮污染环境容量.
On the basis of studying the transformation principle of nitrogen in the middle-stream of the Songhua River the authors found that the change of real measured concentration of ammonianitrogen did not conform to the graded dy- namic model adopted extensively under low water temperature(especially in fre- ezing phase).The real concentration of ammonianitrogen is mainly affected by the speed of transforming organonitrogen into ammonianitrogen and the speed attenuation of ammonianitrogen.And the authors advance that the water quality of model of the Songhua River should be set up with the theory of chemical dynamic successive reaction and estimate the environmental capacity of ammo- nianitrogen pollution in the Songhua River.
