摘 要: | 分析了江西宜春石溪水库的水环境状况,运用沃伦威德尔模型和狄龙模型等水库水环境容量计算方法,对石溪水库COD Mn、NH 3-N、TN、TP的水环境容量进行了计算。结果表明:石溪水库2012年水质为Ⅳ类,营养状态为中营养,入库的污染物量超出其自净能力。将水环境容量按照Ⅲ类和Ⅱ类水标准分为近期目标和远期目标,按近期目标CODM n、NH 3-N、TN、TP的超标率分别为7.6%、86.1%、121.1%、40.7%。在此基础上,分析了石溪水库水污染原因,提出了水污染控制方案。

Abstract: | In this paper,the status of water environment of Shixi Reservoir was analyzed.By use of the calculation methods such as Vollenweider model and Dillion model,water environmental capacity for CODMn,NH3-N,TN and TP in Shixi Reservoir was calculated.The results showed that water quality of Shixi reservoir in 2012 was Class Ⅳ and the nutritional status was in an intermediate level.The amount of pollutants discharged into Shixi reservoir exceeded its self-purification capacity.With regard to the water environmental capacity,a short-term goal was set to reach the Class Ⅲ water standard and a long-term goal was set to reach the Class Ⅱ water standard.According to the short-term goal,the standard rates of CODMn,NH3-N,TN and TP were 7.6%,86.1%,121.1% and 40.7% respectively.On the basis of the above,the causes for water pollution in Shixi Reservoir were analyzed and measures for water pollution control were proposed accordingly. |
