标识指数法在秃尾河流域水质评价中的应用研究

采用现场调研和资料收集相结合的方法收集2007年-2013年秃尾河流域水质参数,以DO、COD、BOD、氨氮、石油类、挥发酚等16项为评价指标,采用水质标识指数法对秃尾河流域水环境状况分别进行单因子评价和综合评价.结果表明:秃尾河历年的综合水质标识指数都未超过水功能区标准;秃尾河的各项单因子标识指数大部分达标,只有COD、BOD、氨氮和石油类有不达标的情况出现,水质治理时可以COD、BOD、氨氮和石油类作为重点指标.

Application of Identification Index Assessment in Tuiwei River Water Quality Evaluation

The water quality of Tuwei River was evaluated through the methods of single factor and comprehensive water qual-ity identification index, based on the data collected by field investigation and data collection from 2007 to 2013. Sixteen water quality evaluation factors included DO, COD, BOD, NH4+ -N, the petroleum, the volatile phenol and so on were discussed. The results indicated the comprehensive water quality identification index of the calendar year of Tuwei River arrived the standard of water environmental function region. Most of the Tuwei River of the single factor identification index arrived the standard of water environmental function region with the exception that the single factor identification index of COD, BOD, ammonia nitrogen and petroleum exceeded the standard sometimes.
