摘要
依据GB3838-2002地表水环境质量标准,对粤东地区东丽湖水的酸碱度量、溶解氧、化学需氧量、生化需氧量、氨氮、总氮、总磷、铜、锌、铅、镉等进行检测,其中总磷、BOD5、COD均劣于Ⅴ类,超标率分别为13%、110%和81.75%;总氮含量为1.87mg/L,属于Ⅴ类水质。富营养化是东丽湖水质污染面临的主要问题,其水质的改善、保护应根据其水质状况、地理位置、环境状况等来综合分析。
DO,pH,COD,BOD5,NH4-N,TN,TP,Cu,Zn,Pb,Cd and so on of Dongli lake by GB 3838-2002 Environmental quality standard of surface water were determined. The result shows that TP, BOD5 and COD are inferior to Ⅴ level, over standard rates are 13%, 110%, 81.75% respectively, and the concentration of TP is 1.87 mg/L,belongs to Ⅴ level. Eutrophication is the major problem in water population of Dongli lake. Improvement and conservation of Dongli lake should base on its water quality, geographical situation, environment and so on.
