河道水体富营养化污染综合治理的研究

Integrative Pollution Control of Urban Eutrophication Rivers

根据丽娃河及丽娃支河污染现状和河道特征,经充分论证后确定综合整治方案,主体工程包括截污、调活水体、水质强化净化和河道生境恢复等,并付诸实施。对比综合整治跟踪监测结果和治理前河道水质状况调查结果显示,综合整治后,DO有了显著提高,NH3-N、TN、TP从治理前的劣Ⅴ类达到地表水Ⅴ类标准,河道的生态环境有了明显的改善等。结果表明,丽娃河采用水质强化和水生态重建方案并举,是行之有效的。

Based on eutrophication status of Liwa River, an integrative renovation scheme including pollution interception, activating water body, water purification and ecological river-restoration was carded out. By comparing the water quality and river landscape before and after the implementation, it was found that DO was improved greatly and NH3-N, TN and TP were removed efficiently, with water quality of the River up to Grade V of Surface Water Standard by GB3838-2002. Results indicated that the pollution control scheme was effective in treatment of urban river eutrophication.
