污染物排放量与河流水质输入响应关系初步研究——小清河(济南段)为例

Study on Response Relationship between Pollutant Emission and River Water Quality——Taking Jinan Section of Xiaoqing River As An Example

污染物排放量与河流水质输入响应关系的建立,是实施排污总量控制的关键。文章以小清河(济南段)为例,将小清河分为睦里庄-还乡店段,还乡店-大码头段和大码头-辛丰庄段,应用一维稳态河流水质模型,确定相应模型参数,与水质实测值相结合,建立污染物排放量与河流水质的输入响应关系,计算响应系数。结果表明:小清河不同段COD的响应系数分别为94.3%、76.7%和76.6%,氨氮的响应系数分别为277.2%、85.7%和58.8%;COD的计算值与实测值比较接近,而睦里庄-还乡店段、大码头-辛丰庄段氨氮的计算值与实测值偏差较大。

The establishment of input - response relationship between pollutant emission and water quality is the key of imple- mentation of total discharge control of water pollution. The input - response relationship between pollutant emission and water quality was established by taking Xiaoqing River in Jinan as an example. The Xiaoqing River was divided into Mulizhaung - Huanxiangdian fiver section, Huanxiangdian - Damatou fiver section, and Damatou - Xinfengzhuang fiver section, the one - dimensional steady water quality mode and corresponding model parameters were determined. The values calculatedon base of theone - dimensional steady water quality mode and measured values wereanalyzed. The results showed that the response coefficient of COD in different fiver sections were 94. 3%, 76.7% and 76. 6%, the response coefficient of NH3 - N in different fiver sections were 277.2%, 85.7% and 58. 8%. The calculated values of COD were close to the measured values, but there were a significant deviation between calculated values and measured values of NH3 - N in Mulizhaung - Huanxiangdian fiver section and Damatou - Xinfengzhuang fiver section.
