为了解蚌埠市龙子湖水质状况,测定了其水中的pH值、溶解氧( DO)、化学需氧量( COD)、总氮( TN)、总磷( TP)、铅( Pb)、铜( Cu)和锌( Zn)等指标,并以《地表水环境质量标准》( GB3838-2002)为依据,采用单项污染指数法和综合污染指数法对其污染程度进行评价。结果显示:龙子湖水体的TP、TN、COD、Pb和Zn超出了Ⅲ类地表水体标准限值;由单项污染指数法评价结果可知,TP为中污染,TN、COD、Pb和Zn为轻污染,pH、DO和Cu为清洁。综合污染指数法评价结果表明,蚌埠学院西门断面为中污染,龙湖大桥断面、淮河风情园断面和珍珠桥断面均为轻污染。
為瞭解蚌埠市龍子湖水質狀況,測定瞭其水中的pH值、溶解氧( DO)、化學需氧量( COD)、總氮( TN)、總燐( TP)、鉛( Pb)、銅( Cu)和鋅( Zn)等指標,併以《地錶水環境質量標準》( GB3838-2002)為依據,採用單項汙染指數法和綜閤汙染指數法對其汙染程度進行評價。結果顯示:龍子湖水體的TP、TN、COD、Pb和Zn超齣瞭Ⅲ類地錶水體標準限值;由單項汙染指數法評價結果可知,TP為中汙染,TN、COD、Pb和Zn為輕汙染,pH、DO和Cu為清潔。綜閤汙染指數法評價結果錶明,蚌埠學院西門斷麵為中汙染,龍湖大橋斷麵、淮河風情園斷麵和珍珠橋斷麵均為輕汙染。

In order to investigate the water quality of Longzi lake in Bengbu city , the index of pH , dissolved oxygen ( DO) , chemical ox-ygen demand(COD), total nitrogen (TN), total phosphorus (TP), lead (Pb), copper (Cu) and zinc (Zn) were surveyed.The meth-ods of single factor pollution index and comprehensive pollution index were used to assess pollution levels in water .The results showed that TP, TN and COD, Pb and Zn were beyond the national surface water environmental quality type Ⅲ(GB3838-2002).The single factor pollution index assessment showed the moderate pollution of TP .The indexes of TN and COD , Pb and Zn displayed light pollu-tion, while pH, DO, and Cu could be regarded as clean levels .According to the results of the comprehensive pollution index method , the section of Bengbu University was the moderate pollution .Meanwhile , the light pollution appeared in the section of Longzi Lake Bridge, Huaihe Style Garden and Pearl Bridge .
