摘　　要：基于水文、水质和污染源资料,建立了大丰区通榆河流域一维水环境数学模型。利用控制断面达标法计算得到通榆河水环境容量,进而与断面现状污染物入河量对比,确定了研究区域内各类污染物的削减量,并对草堰大桥考核断面污染源解析,最终制定断面水质达标方案及可行性分析,为草堰大桥断面乃至通榆河的水环境综合治理提供技术支持。结果证明:草堰大桥断面达到Ⅲ类水要求时,水环境容量分别为:COD 272.66 t/a,氨氮33.77 t/a,总磷7.45 t/a;草堰大桥断面污染源主要为畜禽养殖污染、上游污染及生活污水等。Based on the data of hydrology, water quality and pollution sources, the one-dimensional mathematical model of water environment of the Tongyu River basin was established. The water environmental capacity of the Tongyu River is calculated by using the control section meeting standard method. Then compared with the amount of pollutants discharged into rivers, the amount of pollutants cut was determined. And the sections pollution sources of Caoyan Bridge were analyzed. The plan of meeting the water quality standards and feasibility analysis were applied in order to provide technical support for the comprehensive treatment of the water environment of Caoyan Bridge section and Tongyu River further. The result showed that, when the section of Caoyan Bridge reaches the standards for Grade III water quality, the environmental capacity of COD, NH3-N and TP is 272.66 t/a, 33.77 t/a, 7.45 t/a respectively. The sections pollution sources of Caoyan Bridge are mainly livestock and poultry breeding pollution, upstream pollution and domestic sewage.
