摘要
污染物衰减系数是反映河流水质污染变化情况、建立水质模型和计算河流水环境容量的重要参数。本文采用实测资料分段反算法计算大沽河调水期间COD_(Mn)和氨氮衰减系数,并建立水质数学模型验证衰减系数的适用性。分析结果表明:由衰减系数建立的水质模型计算精度高,此次计算的衰减系数可以应用到大沽水环境容量及河纳污能力等的分析计算中。
The degradation coefficient of pollutant is an important parameter which can reflect the change situation of water quality, set up the water quality model and calculate the water environment capacity of river. The paper utilized segmentation anti algorithm method based on measured data to cal- culate the degradation coefficient of CODMn and Ammonia during water diversion of Dagu river. The wa- ter quality model were built to validate the applicability of degradation coefficient. The results indicated that the water quality model built from degradation coefficient has high accuracy. The degradation coef- ficient in the study can be used to research the water environment capacity and pollution perceiving ca- pacity of Dagu river.
