In the eyes of the common people, blue sky, white clouds, and no odor are the most direct criteria for judging the quality of air.

In 2022, the Party Working Committee and Management Committee of Nantong Economic and Technological Development Zone launched the creation of a "odorless park". During the creation period from July to December 2022, the VOCs concentration in the park decreased by 36% year-on-year, and in 2023, the VOCs concentration in the park decreased by another 25% year-on-year. In 2023, the annual average concentration of fine particulate matter was 25.8 micrograms per cubic meter, ranking first among the seven national control stations in Nantong City.

The achievement of these achievements cannot be separated from the "brain" of pollutant monitoring and management in the jurisdiction - the integrated environmental protection and safety emergency management platform. The platform assists in environmental governance, and the development zone promotes atmospheric governance work in accordance with the concept of "sound monitoring network, precise traceability analysis, and scientific promotion of governance". "Last year, our park received a total of 11 work-related complaints, which is one tenth of the previous year." According to Bu Xiaopeng, Director of the Ecology and Environment Bureau of Nantong Economic and Technological Development Zone, since the establishment of the "odorless park", more than 200 gas related problems have been discovered and rectified in Nantong Economic and Technological Development Zone, with an investment of 250 million yuan in environmental protection. All problems have been tracked and managed through "hanging accounts", achieving "full collection, full treatment, and full supervision" of exhaust gas.

Massive data, intelligent management

On the large screen inside the Ecological Environment Bureau of Nantong Economic and Technological Development Zone, it can be seen that the platform is operating in an orderly manner. Real time data from the air and water quality monitoring points in the park, as well as online monitoring of enterprise pollution sources, are integrated into the network here, making it clear at a glance. At the same time, all key management enterprises in Nantong Economic and Technological Development Zone have installed intelligent terminals for total quantity control. The platform achieves precise control of paid pollution discharge, limited pollution discharge, over discharge valve closure, and total quantity control.

Empowering intelligent supervision with big data, platform construction data traceability analysis, and assisting management personnel in quickly identifying abnormal monitoring data or pollution events. Once an abnormal situation occurs, quickly retrieve the files of surrounding pollution sources, use traceability models and automatic monitoring data, combined with meteorological conditions, analyze the pollution discharge and diffusion paths of surrounding enterprises, and determine the source of pollutant emissions. Provide scientific basis for administrative law enforcement and pollution control through precise traceability.

In terms of point layout, taking atmospheric environment governance as an example, the platform connects 135 key pollution source emission online monitoring stations, 56 enterprises with more than 200 unorganized emission plant boundary stations, 6 park boundary stations, 2 upwind and downwind VOCs stations, 4 standard air stations in the area, 43 grid micro stations, 2 sensitive target stations, and 1 motor vehicle exhaust station; Equipped with a navigation monitoring vehicle, capable of monitoring over 120 types of atmospheric pollutants, and conducting regular or irregular navigation inspections of the park. The staff clicked on a large screen on an information platform and immediately saw real-time air quality data from environmental monitoring points. Once a certain data exceeds the limit, the system will automatically alarm, and the grid responsible person will understand the alarm situation and react quickly in the first time

Combination of peace and war, safety and environmental linkage

The platform builds a daily monitoring and early warning network, warning and risk management mechanism, and emergency support system, highlighting the full process control of risk sources, comprehensively improving regional risk monitoring and early warning and prevention capabilities, transforming passivity into initiative, and forming an emergency management system of "peacetime prevention and wartime linkage". In response to emergencies, we aim to detect, warn, and respond promptly. Provide a guided emergency response process for risk events, assisting operators in completing the entire process from incident response, incident identification, plan initiation, on-site investigation, incident reporting, to on-site command, resource scheduling, emergency rescue, emergency termination, incident assessment, and post disaster reconstruction.

In addition, the platform also has the function of providing feedback to enterprises in environmental management. Build an environmental protection comprehensive service platform with a single enterprise dimension, assign management accounts to enterprises, which is not only a management platform for ecological environment departments, but also a service platform to cooperate with enterprise environmental protection work. Fully communicate and connect with the Nantong Ecological Environment Bureau and horizontal department management departments, prioritize the return of data that can be returned, and strive to present the most valuable data and functions.
