  • 摘要: 针对北运河水系沉积物耗氧污染严重问题，选择凉水河上、中、下游作为研究对象，探讨了沉积物中NH4+-N、TOC、SOD的分布特征，初步判断了沉积物耗氧情况。结果表明凉水河表层沉积物中NH4+-N和TOC含量均较高。其中：NH4+-N在凉水河上游最高，均值为114.38 mg·kg，中游最低，均值为54.06 mg·kg-1；TOC在凉水河上、中、下游依次降低，均值分别为3.64%、3.36%和1.81%。凉水河表层沉积物SOD较高，且变化范围较大，沉积物耗氧污染较为严重。其中：凉水河中游SOD最高，均值为1.012 g·（m2·d）-1；上游最低，均值为0.939 g·（m2·d）-1。
    Abstract: Based on oxygen demand pollution in the typical urban rivers of Beiyun River Basin, Liangshui River was selected for this study. The distribution characteristics of NH4+-N, TOC, and sediment oxygen demand (SOD) in the sediments from the upstream, middle and downstream of Liangshui River were investigated. The results showed that the contents of NH4+-N and TOC in the sediment samples were high. NH4+-N contents were higher in the upstream (mean value 114.38 mg·kg-1), and lower in the midstream (mean value 54.06 mg·kg-1).TOC contents were 3.64%, 3.36% and 1.81% in the upstream, middle and downstream of Liangshui River, respectively. SOD in the middle of Liangshui River was highest (mean value 1.012 g·(m2·d)-1), and lowest in the upstream (mean value 0.939 g·(m2·d)-1).
