摘要
苏州河上海区段底泥中SOD的数据分析表明,市区河段底泥中SOD的大小,与上层河水中COD_(Mn)、DO、BOD_5、NH_3-N的含量均有密切的相关性。在流动水相作用下,研究了水温及流速等主要环境因素对底泥耗氧的影响。提出了市区河段水质模式中的底泥耗氧表达式。指出在市区河段中,底泥耗氧在总的耗氧过程中灵敏度最大,占主要地位。若河流两旁无污染源排入时,约占该河流总耗氧的51％;
The value of SOD in urban reach of Suzhou Creek showed that which has a direct bearing on COD,DO,BOD and NH_3^-N in the upper layer water. On the basis of studying the relations between SOD and some main environmental factors, such as temperature and flow velocity SOD expression pattern has been suggested in mathematical model It showed that sensitivity of SOD was very agile, and sediment oxygen demand might be responsible for 51％ of the total oxygen depletion in urban reach of Suzhou Creek.
