重庆市首个数智化低排放工地“智能门禁”控扬尘|长江奔涌看巴渝

Core Viewpoint - The Chongqing Medical University First Affiliated Hospital's second phase project has implemented a low-emission digital supervision system, marking a significant advancement in pollution control in construction sites in Chongqing, enhancing the city's digital governance capabilities [1][4]. Group 1: Implementation of Digital Supervision System - The project is the first in Chongqing to fully apply a low-emission digital supervision system, addressing the challenges of dust and vehicle emissions in construction sites [1][4]. - The system utilizes GIS technology to establish electronic fences, allowing for automatic vehicle verification and significantly improving regulatory efficiency [2][3]. - The project has already monitored over 780 dump trucks and 9,000 vehicle trips, achieving comprehensive vehicle identification and behavior analysis [2]. Group 2: Dust Control Measures - The system integrates GPS and sensors on construction machinery and dust control equipment, enabling real-time tracking of operations and dust suppression measures [2]. - Dust control devices are activated simultaneously with the operation of heavy machinery, effectively reducing dust emissions at the source [2]. Group 3: Regulatory Effectiveness and Outcomes - The system has established a 24/7 monitoring capability, identifying violations such as uncovered loads and excessive emissions, and facilitating rapid response mechanisms across multiple departments [3]. - Since the system's implementation, there has been a notable improvement in the emission structure of freight vehicles, with a 15% increase in compliance with National VI emission standards [4]. - The air quality in the region has improved, with a decrease in PM10 concentrations, leading to increased public satisfaction regarding air quality [4]. Group 4: Future Developments - The Chongqing ecological environment bureau plans to further optimize the digital supervision system and expand its application across various construction sites and transportation hubs [4]. - The initiative aims to create a new framework for mobile source pollution control characterized by intelligent perception, precise regulation, and collaborative governance [4].
