- Abstract:
- Climate change is one of the threats to human development. Facing the significant increase of extreme rainfall and the continuous expansion of cities, the vulnerability of traditional urban drainage system is becoming increasingly prominent. With the strategic background of carbon neutrality and carbon peaking, it is a scientific problem for planning, design, construction and operation of drainage system on how to systematically build a future oriented sustainable drainage system to improve the reliability and resilience of the drainage system under complex external disturbance factors. In view of the systematic shortcomings of the traditional drainage system, this paper puts forward some suggestions on the key elements in the planning, design and construction of the drainage system, such as water-energy nexus, resilience design, eco-hydrology, and biodiversity. At the same time, this paper analyzes the environmental impact of some current measures, such as the implementation of high discharge standards, extreme high standard denitrification and sewage chlorine disinfection. On this basis, the sustainable drainage system evaluation index system including six first?level indicators and 48 secondary indicators is constructed.
