丹东市大中型水库富营养化评价与防治

通过对丹东市8座大中型水库的基本情况、水质现状和污染源调查,应用综合营养状态指数法对其水质富营养化水平进行评价,得出这8座水库分别处于中营养和富营养状态。分析了造成水体富营养化的主要原因是水库周边工业污染源、生活面源、渔业养殖和蓄水量减少的综合影响,并在此基础上提出有效的污染防治对策。

Based on the status of eight large and middle-scaled reservoirs in DanDong , water quality , and survey on pollutant sources , an assessment of eutrophication level was carried out using the method of aggregative index number . the result shows that the eutrophication in each reservoir ranged between high and middle level . further as the visible eutrophication cause , industrial pollution sources , domestic pollution sources , fishery and cultivating , water volume decrease were pointed out , and some countermeasures were put forward .
