摘要
指出了句容河是秦淮河的重要支流,其水质污染不仅影响城市发展,还会对整体水域水质状况造成威胁,因此,全面了解句容河的水质状况至关重要。采用单因子指数法和内梅罗综合污染指数法2种常用的水质评价方法对句容河的水质进行了评价,结果表明:句容河各断面水质均存在不同程度污染,只有少数断面能达到全年Ⅲ类水质标准,主要污染指标为化学需氧量和氨氮。
Jurong River is an important tributary of the Qinhuai River.Water pollution in Jurong River not only affects urban development,but also poses a threat to the overall water quality.Therefore,a comprehensive understanding of the water quality of Jurong River is of vital importance.The water quality of Jurong River is evaluated by single factor index method and Nemero comprehensive pollution index method.The results show that the water quality of each section of Jurong River is polluted to different degrees, and only a few sections can meet the annual Ⅲ water quality standard. The main pollution indexes are chemical oxygen demand and ammonia nitrogen.
