Research on the Implementation Path of Modular Design and Construction of Smart Environmental Protection Facilities in Waste Free Scenic Spots in Seaside Cities

Coastal scenic areas face significant challenges associated with marine debris accumulation, salt-spray corrosion, and seasonal fluctuations in waste generation. To address these issues, this study proposes a modular implementation framework for smart environmental protection facilities in waste-free coastal scenic areas. Multi-source environmental data are utilized to support adaptive facility deployment, while standardized modular units constructed from corrosion-resistant materials improve environmental durability. A wind–solar–storage microgrid architecture is introduced to enhance energy self-sufficiency, and a digital twin platform is employed for intelligent scheduling and operational management. Experimental results indicate that the proposed framework achieves an energy self-sufficiency rate of 88.2%, reduces overflow alarms by 73%, and significantly improves response efficiency. The study provides a replicable solution for sustainable coastal environmental governance and offers methodological references for wireless sensing, intelligent monitoring, and distributed environmental information systems.
