面向水环境改善的城市河网综合调控研究进展与前沿

Research Progress and Frontiers of Comprehensive Regulation of Urban River Network for Water Environment Improvement

面向日益突出的城市河网水环境改善需求,从支撑技术和管理决策两方面,总结了当前研究进展,并提出了3个待解决的技术难题:(1)城市河道高效适应性水质净化技术和装置;(2)城市河网精细水环境模拟和全局优化调控技术;(3)城市河网水环境改善管理决策支持技术.在此基础上,提出了亟需突破和解决的前沿技术,包括城市河网联动水循环净化系统的集成水质净化技术、城市河网水循环净化系统的水动力-水质耦合数值模拟与综合调控技术、城市河网联动水循环净化系统管理信息平台构建技术,并阐述了技术的研究思路.

Focusing on the increasingly prominent demands of water environment improvement of urban river network,this paper summarizes current research progress from both aspects of technical support and management decisions.Three technical problems which need to be solved are also put forward：（1）High-efficiency and adaptive water quality purification technology and equipment for urban river network;（2）Refined water environment simulation and global regulation technology for urban river network;（3）Decision support technology of water environment improvement management for urban river network.Based on the above three problems,this paper proposes the advanced technologies that need to be broken through and solved urgently for urban river network linked with water circulation and purification system,including integrated water purification technologies,hydrodynamic-water quality coupling numerical simulation and comprehensive regulation technologies,and information management platform construction technology,and then elaborates the research ideas for the technologies.
