摘　　要：为研究浅丘山区中小型尾水补给河道的污染物降解能力,采用多断面高频次人工现场检测的手段,研究了浅丘山区河流双洎河(新密市段)不同水期、不同河段的COD、氨氮的综合降解系数,并用历史监测数据对试验得出的降解系数加以验证,最后应用降解系数对河流出境断面进行水质预测。结果表明,浅丘山区中小型尾水补给河道的降解能力整体偏高,COD、氨氮的降解系数在各水期差异不大,丰水期略高于平水期、枯水期;双洎河(新密市段)出境断面水质预测结果为枯水期COD为16.89mg/L,氨氮为0.859mg/L;平水期COD为16.64mg/L,氨氮为0.825mg/L;丰水期COD为15.07mg/L,氨氮为0.701mg/L,说明污水处理厂的提标改造可以显著改善尾水补给河道水质。In order to study the pollutant degradation capacity of small and medium-sized tail water replenishment channels in shallow hilly areas,the method of multi-section high-frequency manual on-site detection was used to study the comprehensive degradation coefficient of COD and ammonia nitrogen of the Shuangji River(Xinmi City Section)in different water periods and different sections that located in the shallow mountain hilly area.The degradation coefficient obtained by the experiment was verified by using historical monitoring data,and the water quality of the river exit section was predicted.The pollutant degradation capacity was overall high.The degradation coefficients of COD and ammonia nitrogen had little difference in each water period,and it was slightly higher in the high water period relative to the flat water and dry season.The prediction results of the water quality of the exit section of Shuangji River(Xinmi City Section)show that dry season:COD:16.89 mg/L,ammonia nitrogen:0.859 mg/L;flat water:COD:16.64 mg/L,ammonia nitrogen:0.825 mg/L;high water period COD:15.07 mg/L,ammonia nitrogen:0.701 mg/L.It indicates that the sewage treatment plant’s standard upgrading had a significant effect on improving water quality of the tail water supply channel.
