摘要(Abstract)：

以安阳市重要河段“安阳河北士旺公路桥—曹马桥上”为例，运用一维水质模型、湖(库)均匀混合模型进行纳污能力计算.通过增加计算节点，反映各河段不同的水文特征和确定更加符合实际的综合衰减系数，以确保计算结果更加客观、准确.通过对比分析不同情景纳污能力计算结果，深入分析影响城市河段纳污能力大小的主要因素，重点探讨城市河段排污口设置、闸坝工程布局等对城市河段纳污能力的影响程度，为城市河段综合整治和减轻或彻底消除城市河段黑臭水体提供科学依据.
Taking the important urban reach, Anyang River Beishiwang Highway Bridge-Caomaqiao, as an example, one-dimensional water quality model and lake(reservoir)uniform mixing model are used to calculate the pollutant carrying capacity. By adding calculation nodes which can better reflect the different hydrological characteristics of each river section and determine the more practical comprehensive attenuation coefficient, this research tries to ensure that the calculation results are more objective and accurate. By comparing the calculation results of pollutant carrying capacity in different scenarios, the main factors affecting the pollutant carrying capacity of urban reach are analyzed in depth. What's more, This research focuses on exploring the impact of the sewage outlet setting in urban reach and the layout of sluice and dam on the pollutant carrying capacity of urban river reach, providing a scientific basis for comprehensive treatment and reduction or elimination of black and odorous water in urban river reach.
