蒲河单因子水质标识指数法水质评价研究

Pu River Water Quality Assessment Based on the Single Factor Water Quality Identification Index Method

选取CODcr、NH3-N、BOD5、TN、TP五项水质指标,采用单因子标识指数法对蒲河进行水质评价,为环境规划与管理提供科学依据。评价结果表明:在平水期CODcr、NH3-N、BOD5、TN、TP超标率分别为10%、60%、90%、100%、100%,枯水期超标率分别为80%、60%、90%、90%、90%。其中,九龙河入蒲河干流后断面超标最严重。

The five water quality indicators of CODcr,NH3- N,BOD5,TN and TP were targeted and single factor water quality identification index method was used for Pu river evaluation to provide scientific basis for environmental planning and management. The results show that Over Standand rates of CODcr,NH3- N,BOD5,TN,TP are 10%,60%,90%,100%,100% in the flat water,and in the dry season Over Standand rates are 80%,60%,90%,90%,90%. The moat polluted water is found on the cross section of main stream of Pu River after Jiulong River joins in it.
