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(NH3〖CD2〗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;对照2010年污染物入河量,COD、NH3〖CD2〗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。

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 NH3—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 pollutants into the river in 2010, the total maximum annual load of COD and NH3—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 implemented 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.
