Water Quality Analysis and Treatment at Bajiao Cross Section of Mianyuan River
绵远河在德阳的经济发展中具有重要作用，八角断面是绵远河功能区的出境断面，本文首次对德阳市绵远河流域八角断面水环境质量现状及未来趋势，分别利用spea珊叽秩相关系数法和灰色系统模型GM（1，1）趋势因子a法进行了分析和评价，得出NH3-N为现实污染因子的结论，并讨论了污染原因，提出了该断面水环境保护要从多方面着手，对落实绵远河出境水质达标工作具有指导意义。
Mianyuan River plays an important role in economic development of Deyang. Bajiao cross section is at the exit of the river functional zone. For the first time, this paper analyzed and evaluated the status quo and future trend of the water quality at Bajiao cross section using the methods of Spearman rank correlation coefficient and the grey model GM （ 1, 1 ） trend factor alpha respectively. It concluded that the NH3-N was the reality pollution factor. The ca…查看全部>>
