摘要
基于水文、水质和污染源资料,建立了汤水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汤水河水环境容量,根据水文水质同步监测资料进行了后桥头路桥考核断面污染溯源分析,进而制定出近远期水质达标方案,为汤水河乃至秦淮流域的水环境综合治理提供技术支撑。结果表明:2020年后桥头路桥断面水质稳定达标时,汤水河COD、氨氮、总磷水环境容量分别为197.39t/a、18.50t/a、2.22t/a。后桥头路桥断面污染主要源自于句容市和淳化街道,建议两地协作配合,共同促进汤水河的水环境改善。
Based on the data of hydrology,water quality and pollution sources,the one-dimensional mathematical model of water environment of the Tangshui River basin was established.The water environmental capacity of the Tangshui River is calculated by using the control section meeting standard method,and the pollution source analysis of the assessment section of the Houqiaotoulu Bridge is carried out according to the hydrological and water quality synchronous monitoring data.Then the short-term and long-term water quality meeting standard plan is set up,which provides technical support for the comprehensive treatment of water environment in Tangshui River and even Qinhuai river basin.The results showed that when the water quality of Houqiaotoulu Bridge section meets the standard,the environmental capacity of COD,NH 3-N and TP in the Tangshui river is 197.39t/a,18.50t/a,and 2.22t/a respectively.The pollution of the Houqiaotoulu Bridge section is mainly caused by the Jurong City and Chunhua Street,it is suggested that the two places work together to improve the water environment of the Tangshui river.
