摘　　要：以淮河支流洪河为例,选取驻马店洪河西平五沟营-塔桥乡河段,开展河流污染物降解系数室内测定试验,并将室内试验结果与现场实测结果进行对比。结果表明,五沟营-塔桥乡河段降解系数kCOD平均为0.1396 d-1、kNH3-N平均为0.0869 d-1、kTP平均为0.1235 d-1;与国内类似研究结果相比,淮河支流驻马店洪河河段水体的COD和氨氮降解系数处在平均水平之下,应严格控制整个流域的污染物入河量;实验室模拟所得污染物降解系数均小于现场监测值,偏差在15%以内。Taking the Honghe River,a tributary of the Huaihe River,as an example,the river section of Wugouying-Taqiao Township of Xiping of Zhumadian Honghe River was selected to carry out indoor measurement test of river pollutant degradation coefficient,and the indoor test results were compared with the field test results.The results showed that the average kCOD was 0.1396 d-1,the average kNH3-N was 0.0869 d-1,and the average kTP was 0.1235 d-1 in Wugouying-Taqiao Township.Compared with the similar research results of domestic,the COD and ammonia nitrogen degradation coefficients of the water body of the Honghe section of Zhumadian,a tributary of the Huaihe River,were below the average level,and the amount of pollutants entering the river should be strictly controlled.The degradation coefficients of the pollutants obtained from the laboratory simulation were all less than the on-site monitoring values,and the deviation was within 15%.
