新运粮河下游水质监测

摘要

对新运粮河水质进行为期1a的监测，结果表明新运粮河2011—2012年水质为劣Ⅴ类，TP、TN超标严重；各个河段的污染状况为：4＃＞1＃＞3＃＞2＃＞5＃；其水质大部分指标的季节（旱、雨季）变化规律不明确；污染负荷高，CODCr、TP、TN、SS、BOD5为其主要染因子。%The water quality of Xinyunliang River in 201 1 to 2012 was worse than theⅤclass of national water quality standard based on a one-year water quality monitoring data.Five sample sites were monitored along the river.The results showed that the No.4 site was most polluted,followed by the No.1 and the No.3 sites.The No.2 site was worse than the No.3 site.The No.5 site was the worst.Most of the water quality indices didn't show any obvious pat-tern in different seasons in a year.The CODCr,TP,TN,SS and BOD5 were the main pollution factors.
