| 中文摘要: |
| 在分析乐安河沿程水质的基础上，将乐安河全年按丰水期、平水期、枯水期分别统计进出水量、总重金属及溶解态重金属年出入河通量。结果表明：乐安河总重金属质量浓度及溶解态重金属质量浓度呈先上升后下降趋势，出水水质仍能达到Ⅲ类水质标准；2016年乐安河内新增Cu、Zn、Pb质量分别为36968 t、5139 t、0288 t；乐安河内每年可新增重金属量已逐年减少，大量重金属元素将最终排入鄱阳湖内。 |
| 英文摘要: |
| Based on the water quality of Lean river，the water volume, total and dissolved heavy metal flux in and out of Lean river during wet season, normal season and dry season were studied. Results showed that the mass concentration of total and dissolved heavy metal were ascend at first and descend at last. The effluent quality reached the water quality standard of Ⅲ grade. In 2016, the increment of Cu、Zn and Pb in Lean river were 36.968 t, 51.39 t and 0.288 t, respectively. The annual acceptable increment of heavy metals were decreased year by year, and a large amount of heavy metals were discharged into Poyang Lake finally. |
