中新天津生态城水体水质保持技术研究

Research on water quality conservation technology of China-Singapore Tianjin ECO-City

2007年,中国和新加坡两国签订战略合作协议,决定在环境比较恶劣的区域,建设一个"资源节约、环境友好、经济蓬勃、社会和谐"的新型城市,为中国其他同类地区提供借鉴和参考,经过多方优选,最终选定在天津的滨海新区。2008年开工建设,命名为中新天津生态城。生态城建设之初确定了22项控制性指标、4项引导性指标。其中,指标要求2020年,非传统水源利用率达到50%,地表水环境质量达到IV类。本研究通过生态补水和水系连通循环的方式,实现河湖水体的有序流动和强制循环,最大程度地让中新生态城区内河水活起来。通过水系连通,生态补水,实现"水清、水满、水活"的调度目的,有效地改善生态城水环境质量。

In 2007, China and Singapore signed a strategic cooperation agreement, the two countries decided in the area of environment is dirty, the construction of a "resource saving and environment friendly, economic boom, social harmony," a new type of city, to provide reference for other similar areas of China, after optimization, finally selected in tianjin binhai new area.Construction began in 2008 and the city was named china-singapore tianjin eco-city.At the beginning of eco-city construction, 22 control indicators and 4 guidance indicators were determined.Among them, the target requires the utilization rate of non-traditional water sources to reach 50% and the surface water environment quality to reach class IV by 2020.This study realizes the orderly flow and forced circulation of river and lake water by means of the river pumping station and the use of sluice culvert to control the water level of the river, so as to make the river in china-singapore eco-city alive to the greatest extent.A oneway flow is formed in the landscape water body. By increasing the flow, optimizing the landscape water level and controlling the water level, the dispatching purpose of "clear water, full water and live water" can be realized, and the water environment and landscape in the ecological city area can be effectively improved.
