天津生态城水治理模式的探索与研究

Exploration and Research on Water Management Model in Tianjin Eco-city

天津生态城在10年建设和发展过程中,通过借鉴新加坡经验并因地制宜,在水治理标准化体系构建、水安全保障、水环境改善和水资源优化等方面进行了有益探索。制定了《安全供水与应急导则》《节水导则》和《非传统水资源管理利用导则》,在全国率先建立了《中新天津生态城指标体系》,形成《中新天津生态城水务管理导则》体系;治理2.56 km2的污水库存量污染,实施汇水分区并保证透水性地面不少于45%等低影响开发策略,建立供水监测机制,以保障水安全;提升污水排放标准以满足生态补水水质水量需求,强化入河径流生态净化,进行水体连通循环,改善水体环境;开展水量平衡匹配、科学用水决策,优化配置水资源,非传统水源利用率已超过60%;实施集水质监测、处置预警、应急调度于一体的闭环式智能化水务管理。目前天津生态城已形成了日臻完善的科学水治理模式,可为其他城市水治理提供参考和借鉴。

During 10 years construction and development of Tianjin Eco-city,through drawing lessons from Singapore’s experience and adapting measures to local condition,beneficial explorations on the construction of standardization system of water treatment,water security guarantee,improvement of water environment,optimization of water resources and other aspects have been made in Tianjin Eco-city:the Guidelines for Safe Water Supply and Emergency Response Water Saving and Non-traditional Water Resources Management and Utilization were formulated,and The Index System of Sino-Singapore Tianjin Eco-city was first established in China,thus forming the system of Sino-Singapore Tianjin Eco-city Water Management Guidelines.The stock pollution of 2.56 km^2 wastewater reservoir was controlled,the catchment area was implemented.Then,the permeable surface was ensured not less than 45% and other relevant low-impact development strategy,and the water supply monitoring mechanism was built to ensure water security.Through upgrading wastewater discharge standards to meet the water quality and quantity of ecological recharge water,strengthening ecological purification of runoff into rivers,connecting water system and promoting water circulation to improve water environment, carrying out water balance matching to increase the science of water application decisions and optimize allocation of water resources,now the utilization rate of non-traditional water resources of Tianjin Eco-city has exceeded 60%.Meanwhile,Tianjin Eco-city implemented a closed-loop intelligent water management system that integrated water quality monitoring,early warning and emergency response.At present,an improving scientific water management model has been formed in Tianjin Eco-city,which can provide reference for other urban water management.
