京杭运河(苏州段)污染负荷核算及源解析

Pollution load calculation and source apportionment of Beijing-Hangzhou Canal(Suzhou section)

以流域污染负荷核算为重点,对京杭运河(苏州段)两岸涉及的5个区20个街道各污染源负荷进行核算,对污染源进行系统、高精度分析,明确排污单元,核算污染贡献,根据各区及各街道水污染源解析结果,形成重点整治内容的各控制单元。研究为削减氨氮和总磷的总量提供数据支撑,为各项水污染防治提供技术支持和科学指导。

Focusing on the basin pollution load accounting,the paper calculated the load of each pollution source of 20 streets in 5 districts on both sides of Beijing-Hangzhou Canal(Suzhou section),made a systematic and high-precision analysis of the pollution sources,defined the pollution discharge unit,calculated the pollution contribution,and formed each control unit of the key remediation content according to the water pollution source analysis results of each district and street.The study provided data support for reducing the total amount of ammonia nitrogen and total phosphorus,and provided technical support and scientific guidance for water pollution control.
