摘    要:以通榆河南段控制单元为研究区,利用现有的平原感潮河网区水量模型、面源污染负荷统计模型和水环境容量模型,估算研究区2010年污染物最大日负荷总量(TMDL),并进行负荷削减和分配研究。结果表明:研究区COD、氨氮(NH3-N)90%保证率(2004年)下的水环境容量分别为7.76万t,0.37万t;xCN2010年污染物入河量,COD、NH3-N的最大年负荷分别为1.99万t,0.28万t。在研究区涉及的各县市中,海安、姜堰、东台是负荷削减的重点区域;对于不同的污染源,城镇生活点源和农业面源是研究区污染物总量控制的关键。

关 键 词:最大日负荷总量  削减  分配  通榆河

Abstract:TMDL(Total Maximum Daily Load) of Tongyu River southern reach control unit in 2010 was calculated based on the existing tidal river network water model, non-point source pollution load statistical model and water environmental capacity model.. Load reduction and allocation was then studied. The result showed that the water environmental capacity of COD and NH3--N under 90% guarantee rate in the studied area were 77 600 t per year and 3 700 t per year, respectively. Compared to the amount of pollu- tants into the river in 2010, the total maximum annual load of COD and NH3--N in the studied area were 19 900 t per year and 2 800 t per year, respectively. Among the county-level cities involved in the studied area, load reduction should be mainly implemen- ted in Haian, Jiangyan, Dongtai. In terms of different pollution sources, total amount control of pollutants should be preferentially focused on urban domestic pollution source and agricultural non-point source.
Keywords:TMDL( Total Maximum Daily Load)  reduction  allocation  Tongyu River
