Under the strong "hydrogen" wind, the "temperament" of Jiaxing Port Area cities continues to improve

Summer is strong, and white clouds float freely in the blue sky. Recently, the circle of friends of citizens in Jiaxing Port District, Zhejiang Province has continued to be dominated by blue skies and white clouds. The reporter learned from the Zhejiang Zhapu Economic Development Zone Branch of the Ecological Environment Bureau of Jiaxing City that in the first half of this year, the average air quality rate in the port area was 88.5%, and the ozone concentration reached 138 micrograms/cubic meter. Both indicators ranked second in Jiaxing City.

Behind the data is that the port area focuses on the continuous improvement of air quality, pays close attention to the source of air pollution, optimizes the green industrial structure, carries out comprehensive management in key areas, strengthens multi-department linkage and coordination, and improves the systematicness of atmospheric environmental management.

On the busy Jiaxing Port terminal, white, blue and green-painted hydrogen energy trucks (i.e. hydrogen energy heavy trucks) shuttle between them in an orderly manner. They are not only a strong driving force for cargo transportation, but also a green and low-carbon transportation. An important breakthrough in transportation methods. Hydrogen energy collection trucks use hydrogen fuel cells as power sources to continuously output electrical energy through the electrochemical reaction between hydrogen and oxygen to drive the vehicle, thereby achieving zero carbon emissions.

The normal operation of hydrogen energy collection trucks is a true reflection of the port area's continuous optimization of the industrial energy structure and acceleration of green, low-carbon and high-quality development. In recent years, the port area has taken "hydrogen energy + chemical industry" as the main line, giving full play to the advantages of sufficient industrial by-product hydrogen resources, gathering leading hydrogen energy equipment manufacturing enterprises such as takin hydrogen energy, and building a "hydrogen-using" entire industrial chain. So far, a total of 80 hydrogen energy trucks have been put into operation, and carbon emissions are expected to be reduced by 4000 tons per year.

Under the strong "hydrogen" wind, the port area has taken the construction of national-level collaborative innovation pilot projects for pollution reduction and carbon reduction as the starting point to solidly promote the green and low-carbon transformation of industry and energy. The relevant person in charge of the Ecological Environment Branch told reporters that Jiaxing Port Area strictly adheres to the two major barriers of environmental assessment and energy assessment, resolutely curbs the blind development of high-energy-consuming, high-emission, and low-level projects, and controls the increase in emissions at the source. Since the beginning of this year, 6 "two highs and one low" enterprises have been renovated, 294 acres of inefficient land have been vacated, and 46,000 tons of backward energy-consuming standard coal have been eliminated.

The three colors of white, green and blue hydrogen energy collectors have become a beautiful scenery for the port area and terminal. However, in the chemical industry park, a "magic car" with unique functions-VOCs cruising vehicle, also "quietly" protects the air quality of the port area through cruising monitoring.

A set of monitoring data beats every 5 seconds to detect more than 100 pollution sources in the ambient air in real time... The carrier is equipped with advanced monitoring equipment, which can quickly and accurately monitor air quality and reflect the distribution of pollutants. Inside the car, the private smell sniffers and law enforcement officers carefully observed the changes in the line chart on the screen. When the passenger vehicle detects abnormal pollutant concentrations, it will immediately stop the car for monitoring at a fixed point, and notify the private smell sniffers to get off the bus for on-site inspection. This organic combination of machine monitoring and manual sniffing has greatly improved the efficiency and accuracy of environmental monitoring and ensured that pollution sources have nowhere to hide.

In response to the discovered pollution sources, the port area continues to carry out comprehensive management of VOCs and promote PM in accordance with the "Special Action Plan for the Prevention and Control of Volatile Organic Pollution in Zhapu Economic Development Zone (Jiaxing Port Area)(2023-2025)"_2.5Coordinate control with ozone to strengthen exhaust gas terminal management and law enforcement supervision.

"Since May this year, we have also carried out performance rating work on air pollution prevention and control of enterprises in key industries, guiding 15 enterprises in the region to formulate and implement upgrading work plans based on Class A enterprise standards, so as to improve the atmosphere of industrial enterprises in the port area as a whole. Pollution prevention and control level, cultivate and create a number of leading enterprises." The relevant person in charge said.

In addition, the Ecological Environment Branch has also joined forces with Zhapu Town, the Natural Resources and Planning and Construction Bureau, the Comprehensive Law Enforcement Branch, the Public Security Branch, the Market Supervision Branch and other departments to continue to fight the battle against air pollution in multiple directions and in multiple fields to carry out joint law enforcement methods such as road inspections and household supervision and sampling testing to crack down on illegal activities such as excessive emissions from diesel trucks, and comprehensively grasp the prevention and control of pollution emissions from mobile sources. Since the beginning of this year, a total of 7 joint law enforcement operations for road inspections have been jointly carried out, and 126 diesel trucks and 35 diesel vehicles have been sampled and tested. In the future, the port area will continue to focus on source governance, highlight major areas, key industries and key links, deepen the battle to defend the blue sky, and polish the ecological background of high-quality development in the port area.
