本文中，针对流域污染物最大允许纳污量进行研究通过构建常州运河以北研究区

In this paper, the maximum allowable amount for watershed pollutant contaminants research by building a canal north of Changzhou Research hydrodynamic water quality model region, on the basis of the status quo on emissions, thus changing the status quo of water environment north of the Canal by providing some D.

In this paper, the study on the maximum allowable amount of pollutants in the basin provides a certain reference significance for changing the current situation of water environment north of Changzhou Canal by constructing a model of hydrodynamic water quality in the study area north of Changzhou Canal, on the basis of the current discharge of pollutants.

In this paper, the study on the maximum allowable amount of pollutants in the river basin through the construction of the hydrodynamic water quality model of the research area north of Changzhou canal, on the basis of the current discharge of pollutants, thus providing a certain reference for changing the current situation of the water environment north of Changzhou canal.<br>
