芜湖龙窝湖水质现状评价

Water Quality Assessment of Longwo Lake in Wuhu City

在芜湖龙窝湖选择6个样点,采集表层水样,测定水体总氮(TN)、氨氮(NH3-N)、总磷(TP)以及化学需氧量(CODCr)指标,评价了龙窝湖水体水质状况。结果表明:龙窝湖春季水体中TN的含量为1.50～7.42mg/L,NH3-N含量为2.58～6.67 mg/L,TP含量为0.029～0.288 mg/L,CODCr浓度为16～46mg/L。样点水质指标达标率和各指标的样点达标率均低于50%。龙窝湖水质氮、磷指标未满足《地表水环境质量标准》III类水域水质标准。

Six surface water samples were collected to study water quality in Longwo Lake, Wuhu. The total nitrogen（ TN）, ammonia nitrogen（NH3- N）, total phosphorus（TP）, chemical oxygen demand（ CODcr） were determined and the result showed that TN, NH3 - N, TP and CODcr was between 1.50 - 7.42 mg/L, 2.58 - 6.67 mg/L, 0.029 - 0. 288 mg/L and 16 - 46mg/L respectively. The standard - reaching rate of water quality index and sampling plots was between 0% - 50% , which showed that water quality in Longwo Lake can not meet the standard for III kind of waters of water environment quality standard.
