Shanxi Changzhi: How to refresh the blue sky transcript?

The Taihang Mountains are towering and magnificent, and the north and south are hundreds of miles. There is a rich plateau basin between the southern section of the Taihang Mountain and the Tauru Mountain. Changzhi City, Shanxi Province is located, the name is taken from the meaning of "Changzhi and Safe".

As one of the "2+26" cities of Beijing -Tianjin -Hebei air pollution transmission channels, the practice exploration of Changzhi has been used for several years to achieve the average concentration of PM2.5 from 69 micrograms/cubic meters in 2016 to 38 micrograms/cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic The breakthrough of rice has become a "dark horse" for air pollution control.

Xiaoxian County is no longer "trapped by coal"

It was a real portrait of Xiangyuan County, Changzhi City due to coal and being trapped by coal. Xiangyuan County is rich in mineral resources. The coal is the most. It is currently proven 7.58 billion tons of coal reserves, which is one of the national high -quality power coal production bases.

When economic activities are mainly based on industries such as coal mining, coal chemical industry, and thermal power generation, coal has brought unprecedented material wealth to Xiangyuan, but it also brings a serious pollution with large emissions and high concentrations to Xiangyuan. It was once ranked in the countdown of Changzhi City.

"It's really exaggerated. At that time, when I went out, I didn't dare to wear light -colored clothes. When I came back, I was in a soil, and there was a black dust." Jia Hang from Shangcun Village, Southeast Village, Guhan Town told reporters.

This situation also plagued Zhao Huimei, who was once troubled by the northwest of Xiadian Town. She told reporters: "Our village originally belonged to Fuyang Industrial Park. The surroundings of the village were distributed with coking plants, power plants, and coal washing plants. In the past, we could see the black smoke and yellow smoke of coking plants and power plants at home. There is another black and gray at night. After washing the clothes, I didn't dare to dry in the yard at all.

In the face of the increasingly complicated situation of atmospheric pollution and the improvement of the quality of the atmospheric environment, especially the coking and thermal power industries, it has always been a large discharge of air pollutants in Xiangyuan County and the focus of air pollution control.

In three years, Xiangyuan changed the situation of "black smoke covering the sky" and "dust permeating" in some key areas. In recent years, Xiangyuan has implemented ultra -low emission transformation on the thermal power industry, and the focusing of special emission limit transformation has been carried out. Coking plants, thermal power plants, coal mines, coal washing plants, and building materials industries are stored in the past, and they have changed the situation in the past, and now they have all built tube warehouses and steel structures or gas membrane material sheds. The main import and export installation without organization dust online monitoring equipment, the level of pollution prevention and control has been significantly improved.

"It's not the same now. I don't need to consider a lot of white T -shirts. Today I wore small white shoes. After walking for a while, the shoes were still clean. Enhance the sense of gain. Nowadays, the quality of the air environment in Xiangyuan County has steadily risen, and the average PM2.5 concentration has dropped to less than 40 micrograms/cubic meter. The excellent environmental air quality of the year has reached more than 270 days. The continuous exploration of Xiangyuan has also become a microcosm of Changzhi atmospheric pollution.

A group of people change a city

As a member of the "2+26" city, the improvement of the air quality of Changzhi is inseparable from such a group of people. This group of people was ordered to "diagnose the pulse" for the cities. Aiming at the "2 + 26" cities in Beijing, Tianjin -Hebei and surrounding areas with severe air pollution, implement the "charter production to households" follow -up research mechanism, conduct guidance in the station, master the first -hand information of prevention and control work, and propose "one city, one policy" Comprehensive air pollution solution.

Changzhi is one of the cities that this group of people pay attention to. The team of Professor Peng Lin of North China Electric Power University came to Changzhi a few years ago to study in to study.

From the laboratory to the streets of Changzhi, from the hot summer to the cold and winter, there has always been their figure. On -site research, follow -up research, scientifically analyzes the source of air pollutants, deeply excavate the cause of pollution, and propose suggestions for pollution prevention measures targeted.

As a 4 -year -old father, Yan Yulong, a teacher of the North China School of Electric Power University, who stationed in Changzhi, often lacked the growth of the child. Over the year, he has traveled more than dozens of times between Beijing and Changzhi City. The time of nearly half of the year was either a business trip or on a business trip.

"At the beginning, the residents saw that the members of our team sampled at their doorstep, and there would be uncomfortable situations and unwilling to stay. A few years have passed. The improvement of air quality has allowed people here to understand our responsibilities and recognize our responsibilities and recognize it. Our job. "When talking about the changes of Changzhi, Yan Yulong said comfortably.

By carrying out the analysis of the source of air particulate matter, the team has established the use of carbon isotope technology to analyze air particulate matter and organic pollutant sources, help scientific decision -making, and innovate the analysis method of particulate matter source and ozone sources based on isotopes. Refined analysis of objects and launching a series of regulatory methods of "scientific analysis -promotion decision -effective regulation -post -post evaluation".

Efforts to live up to careless people, and the blue sky and white clouds of Changzhi are increasing. In 2021, Professor Peng Lin's team was approved by the "Prime Minister Fund" second phase of the "one city and one strategy" project, which will continue to provide strong scientific and technological support for Changzhi's atmospheric PM2.5 and O3 collaborative control.

The pollution control is increasingly accurate, and the model is constantly upgrading

In 2021, Changzhi City obtained the "two breakthroughs" in the improvement of the quality of the atmospheric environment. One was the first time the PM2.5 average concentration in the urban area entered the "30+" (reached 38 micrograms/cubic meter), and the second was the first time that the proportion of excellent days reached 75.4 for the first time. %Or more (reached 79.2%, 289 days). Behind the results is the continuous innovation of pollution control model. The transformation, governance of enterprises, coal reduction, car control, and dust reduction "five tubes", and the rectification of the atmospheric environment has continued to increase. The pollution control is more accurate, the model continues to upgrade, and the investigation of grass -roots law enforcement depends on the "carpet type" investigation has also become a past.

"With the continuous upgrading of corporate pollution governance technology, coupled with the gradual investment in an information supervision system such as online monitoring of key pollution sources, accurate monitoring of atmospheric mesh, and online surveillance without organizational emissions. Zhang Chunyu, deputy captain of the comprehensive administrative law enforcement team of Xiangyuan County, told reporters that through automatic monitoring system data, combined with the analysis of the research and judgment of the expert team, the law enforcement work is accurate. Carry out on -site inspections, also flexibly and dynamically implement negotiation and emission reduction, characteristic pollutants emission reduction, and the accuracy and targetedness of law enforcement work are more prominent.

In recent years, Changzhi has not only completed the completion of the excess capacity of traditional industries, but also closed up 12 coal mines, but also 13 coal -fired power plants, 5 steel companies, and 5 cement clinkers in the city have completed ultra -low emissions transformation. Enterprises complete ultra -low emission transformation, and 1079 "scattered and polluting" enterprises have completed comprehensive rectification ...

In June, the General Office of the State Council issued the "Notice on the implementation of major policies and measures for the implementation of major policies and measures in 2021". Essence The numbers are constantly changing, and the dazzling transcripts are constantly refreshing. Changzhi this Taihang "Pearl" will also embrace more blue sky.
