- Abstract:
- Based on the relevant concepts of gray infrastructure and green infrastructure, as well as the understanding of the challenges and issues related to single infrastructure systems, this paper summarizes the concept of gray-green synergy and its implications in three aspects: efficient resilience, composite utilization, and green and low-carbon. On this basis, based on the practical case of sewage purification plant in the Hengqin Guangdong-Macao in-deep cooperation zone, three strategies for the gray-green synergy of sewage treatment plants were explored: maximizing the benefits of land three-dimensional composite utilization; overlaying ecological engineering methods to enhance sewage purification efficiency; emphasizing process innovation to achieve full resource and energy circulation, and creating a zero-carbon park through carbon emission reduction and carbon sequestration. Finally, the paper proposes interdisciplinary collaborative technologies for multi-dimensional gray-green symbiosis and discusses the future potential of digital integration and optimization, offering recommendations for advancing the construction of ecological municipal gray-green synergy.
