修正内梅罗污染指数法在广州市河涌水质评价中的应用
|
摘要
河流水质评价是水环境治理的重要基础工作。对于污染严重的河流(如劣Ⅴ类水质),水质往往经过长期的整治仍未发生好转,现行的水质评价方法不能反映水质在不同时段的变化趋势。本论文提出了利用修正内梅罗污染指数法对广州市典型河涌水质进行综合评价,并将其与单因子评价法及传统内梅罗污染指数法进行对比研究。结果表明,修正内梅罗污染指数法能够有效评价广州市河涌水质的污染现状和变化趋势,突显河涌长期治理成效。该方法为广州市河涌综合整治效果评估提供理论指导和技术支撑。
Water quality evaluation is an important foundation of water environmental management. For the river which is heavily polluted, such as water quality worse than Grade V, when the water quality category has not changed, current water quality assessment system often fails to reflect variation tendency of the same river at different times. In this paper, amendatory Nemerow index was applied to the comprehensive evaluation of water quality evaluation of Guangzhou city, and the calculation results were also compared with single factor evaluation method and traditional Nemerow index method. Results show that amendatory Nemerow index can objectively reflect the water quality evaluation of Guangzhou city and highlight the governed effectiveness. The amendatory Nemerow index may provide the theoretical basis and technical support for the evaluation of remediation effect.
