- Abstract:
- Urban water security serves as the foundation of urban security and the basis of life and health maintenance. The drainage system acts as the crucial link between human life and health and water environment, clean water supply and the management of domestic waste. By examining the development history of drainage system, this study analyzed the general characteristics of the drainage system in three historical periods: ancient drainage system based on water utilization, modern drainage system with sanitary driving type, modern drainage system with water quality and quantity driving type. And then，the overall technical characteristics of sewage biological treatment stages were summarized. With the increasing extreme rainfall frequency due to global warming and the external environmental constraints such as the “dual carbon”strategy, the challenges of the traditional urban drainage system were analyzed. In response, it is suggested to construct a sustainable urban drainage system oriented to future climate adaptation， and to achieve the functional transformation for modern drainage system from water quality and quantity oriented to climate adaptive systems. The “Safe & SuRe” criteria for constructing climate adaptable drainage system from a watershed perpective was analyzed. And the “downscaling” overall technical route and concept based on climate-driven model simulation and prediction were introducted. Additionally, pathways for achieving basin coordination, converting resource source to energy and resource utilization, and implementing real?time control system from the perspective of smart basin were also proposed.
