摘　　要：根据千岛湖水质现状和水功能区划,确定2015年和2020年千岛湖水质保护目标的污染物浓度,核算现状污染负荷量。将现状CODMn、NH3-N和TP污染负荷量作为千岛湖CODMn、NH3-N和TP的纳污能力,即千岛湖湖区CODMn、NH3-N和TP指标纳污能力分别为16 420 t/a、2 225 t/a和434 t/a。采用狄龙模型核算千岛湖TN指标的纳污能力,2015年千岛湖TN质量浓度目标值为0.88 mg/L,对应湖区限排总量为3 468 t/a;2020年将千岛湖TN质量浓度目标值进一步提高至0.8mg/L,此时对应湖区TN限排总量为3 176 t/a。Based on the current water quality and water function zones of Qiandao Lake , the pollutant concentrations that will meet the water quality requirements in 2015 and 2020 were determined , and the current pollutant loads were calculated .The current pollutant loads of COD Mn , NH3-N, and TP were examined , in order to study the environmental capacity of the lake .The lake’s capacities of CODMn, NH3-N, and TP, were 16 420 t per year, 2 225 t per year, and 434 t per year, respectively.The Dillon model was used to calculate the pollutant capacity of TN in the lake .The results show that the target TN concentration will be 0.88 mg/L for the year 2015 , and the corresponding total pollutant discharge limit will be 3 468 t per year .In the year 2020 , the target TN concentration will decrease to 0.8 mg/L, and the corresponding total pollutant discharge limit will be 3 176 t per year.
