城市河湖水体综合整治与品质提升技术研究及示范应用

Technical Research and Demonstration on Comprehensive Rehabilitation and Performance Improvement of Urban River and Lake Waters

城市河湖水体水质的下降、水体景观与生态功能的缺失,对城市水体生态功能和人居环境品质的提升造成了严重影响。在全面推进生态文明建设和美丽中国实现的新时代背景下,如何构建适合于我国城市河湖水体综合整治和功能品质提升的系统性解决方案迫在眉睫。随着国家水体污染控制与治理科技重大专项的实施,经过一系列城市河湖水体监测、评估、治理与修复技术的研发与示范应用,总结凝练出“城市水体监测评估—污染负荷控制—水体水质提升—生态功能恢复”的全链条技术体系,有效解决了我国城市河湖水环境监测评价、水污染控制、水环境整治、水生态恢复的技术问题。在天津、重庆、安徽等重点流域、区域的示范应用验证了水专项技术成果的系统性和实用性,促进了城市河湖水体整治技术的发展与规模化应用,为我国城市水环境工程相关科研、设计、建设、运维和监管人员提供了可参考借鉴的技术方案和工程经验。

The decline of water quality and the lack of landscape and ecological functions of urban rivers and lakes have seriously affected the ecological functions of urban water bodies and the improvement of the quality of human living environment.In the new era of comprehensively promoting the construction of ecological civilization and a beautiful China,it is urgent to build a systematic solution,which is suitable for the comprehensive improvement on the quality and function of urban rivers and lakes in China.A series of research,development and demonstration application of urban river and lake water body including monitoring,assessment,management,and restoration technologies were performed.With the implementation of the National Science and Technology Major Project for Water Pollution Control and Management,the whole technical chain of“urban water body monitoring and assessment-pollution load control-water quality improvement-ecological function restoration”has been summarized.It has effectively solved the technical problems such as water environment monitoring and evaluation,water pollution control,water environment remediation and water ecology restoration in urban rivers and lakes in China.The demonstration and application in key watershed areas such as Tianjin,Chongqing and Anhui have verified the systemic and practical advantages from the outcomes of the water special projects.These outcomes promoted the technical development and large-scale application in urban river and lake water.The technical research and practical application provided technical solutions and engineering experience to researchers,designers,constructors,operators,and supervisors who work for urban water environment projects in China.
