流域水环境综合治理集成技术应用研究
|
摘要
城镇化快速发展带来水资源紧缺、水污染严重和生态环境脆弱等突出矛盾和问题,严重破坏河道水环境质量。为解决水环境污染问题,国内外学者在水治理领域研究多年,提出多种技术措施。结合近年来河道治理的关键技术和工程实践,提出以生态修复为核心的综合治理集成技术的应用研究,并将此技术理念应用于云南小清河的水环境提升中。结果表明:采用以生态修复为核心的集成技术治理模式,河道水质由劣Ⅴ类提升至准Ⅳ类,且COD、TP、NH_3-N等污染物浓度显著降低,水质明显改善,生态系统逐渐恢复,水体自净能力显著提升。
The rapid development of urbanization has brought about outstanding contradictions and problems such as water shortage, serious water pollution and fragile ecological environment, which have seriously damaged the water environment quality of rivers. In order to solve the problem of water environmental pollution, scholars at home and abroad have studied in the field of water treatment for many years, and put forward a variety of technical measures. Based on the key technologies and engineering practices of river regulation in recent years, the application research of integrated management technology with ecological restoration as the core is put forward, and this technology concept is applied to the improvement of water environment of Xiaoqing River in Yunnan. The results showed that the water quality of the river was improved from inferior V to quasi IV by using integrated technology with ecological restoration as the core. The concentrations of pollutants such as COD, TP and NH_3-N are significantly reduced,the water quality is significantly improved,the ecosystem is gradually restored, and the self-purification ability of the water body is significantly improved.
