[ Focus on Chemical Machinery Equipment Network ] Today (November 16), Hangzhou seems to have ended the blue sky and white clouds for several consecutive days.
When I went out in the morning, the editor found that the sky became gray.
Although it was not as serious as the smog, the air quality had also changed from "excellent" to "good".
There may be 200 meters of intensity fog in some areas, and air pollution in some areas.
The editor here reminds everyone to pay attention to safety when going out.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentWhen I went out in the morning, the editor found that the sky became gray.

There may be 200 meters of intensity fog in some areas, and air pollution in some areas.
The editor here reminds everyone to pay attention to safety when going out.
In addition, the weather forecast shows that because the cold air is still relatively "weak", my country's weather stage as a whole still maintains a large pattern of sparse rain and snow and high temperatures.
It is expected that it will not usher in a more obvious turning point until the 17th.
Due to the calm and stable weather, the fog and haze in the North China Plain have also taken the opportunity to "add play".
It is expected that there will be heavy haze in Tianjin, southern Hebei, northern Henan and other places.

The problem of smog control has long become the primary environmental problem to be solved in major cities.
The smog, known as the "winter killer", has not only endangered human health in recent years, but also affected the development of transportation, but also caused a trillion in economic losses a year, and the indirect losses are even more unpredictable.

What is the harm when the smog is coming?
Haze weather is a state of atmospheric pollution.
Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.
5 (particulate matter with aerodynamic equivalent diameter less than or equal to 2.
5 microns) is considered to cause haze The "culprit" of the weather.
With the deterioration of air quality, the phenomenon of haze weather has increased and the damage has increased.
Many regions in China incorporate haze weather phenomena into fog as early warning and forecasts of severe weather.

With the deterioration of air quality, the phenomenon of haze weather has increased and the damage has increased.
Many regions in China incorporate haze weather phenomena into fog as early warning and forecasts of severe weather.
According to data, there are more than 20 kinds of fine particles and toxic substances harmful to the human body in the fog, including acids, alkalis, salts, amines, phenols, etc.
, as well as dust, pollen, mites, influenza viruses, tuberculosis, pneumococcus, etc.
The content is dozens of times that of ordinary atmospheric water droplets.
, as well as dust, pollen, mites, influenza viruses, tuberculosis, pneumococcus, etc.
The content is dozens of times that of ordinary atmospheric water droplets.
Compared with fog, haze is more harmful to human health.
Because the fine powdery floating particles in the haze are generally below 0.
01 microns in diameter, they can directly enter the bronchial tubes and even the lungs through the respiratory system.
Therefore, it is the human respiratory system that haze has the greatest impact, and the diseases caused are mainly concentrated in respiratory diseases, cerebrovascular diseases, nasal inflammation and other diseases.
At the same time, in the haze weather, the air pressure drops, the inhalable particles in the air increase sharply, and the air mobility is poor.
The spread of harmful bacteria and viruses to the surrounding area slows down, resulting in an increase in the concentration of viruses in the air and a high risk of disease transmission.

No need to be afraid of "smog", our country is acting
It is reported that the haze weather in northern China has reduced the life expectancy of northern residents by 5.
5 years on average.
my country has been taking action to control smog.
5 years on average.
my country has been taking action to control smog.
In order to further promote the comprehensive treatment of air pollution, continue to improve air quality, and strive to win the blue sky defense war, and build a beautiful China, during the "13th Five-Year Plan" period, the "Three-Year Action Plan for Winning the Blue Sky Defense War" will be issued to countries in the next three years.
Air pollution prevention and control work is deployed.
Air pollution prevention and control work is deployed.
The overall goal of the Action Plan is to drastically reduce the total emissions of major air pollutants after three years of hard work, coordinate reduction of greenhouse gas emissions, further significantly reduce PM2.
5 concentration, significantly reduce the number of days of heavy pollution, and significantly improve ambient air quality , Obviously enhance the people's blue sky happiness.
In order to further develop the basic environmental monitoring project, in September 2019, * reviewed and approved in principle the "Ecological Environment Monitoring Planning Outline (2020-2035)".

It can be seen that my country is also continuously strengthening environmental protection efforts.
In recent years, various provinces and cities across the country have been scrambling to build environmental monitoring networks.
Therefore, we do not need to be afraid of "smog".
my country has been taking action to prevent and control smog, and its monitoring must be carried out first.

Monitoring instruments are also protecting us
Monitoring instrument When haze occurs, the top priority is how to cause haze and how to adopt corresponding strategies.
From the above, it can be seen that the haze problem is caused by a large number of fine particles emitted by the economic and social activities of a high-density population.
(PM2.
5) is often difficult to fundamentally solve, the problem of haze control has been mentioned at the forefront of the storm, and in response to this phenomenon, environmental monitoring instruments have gradually become the target of everyone's hot hands.

The environmental monitoring instrument industry refers to the manufacture of * instruments and meters that monitor pollutants in water and air, as well as noise, radioactive materials, electromagnetic waves, etc.
Environmental monitoring instruments and meters mainly include five categories: ambient air detectors, smoke and smoke monitors, water quality monitors, particulate matter samplers, and data collectors.
Its monitoring methods include all methods that can characterize environmental quality such as chemistry, physics, biology, etc.
; monitoring objects include objects such as air, water, soil, solid waste, and biology.
In addition, due to the spatio-temporal characteristics of environmental pollution, only by insisting on * measurement, can we reveal its changing laws from a large amount of data.

In the "smog and haze" monitoring, a single air monitoring instrument is already "powerless".
Relying on its own strength to achieve multi-angle anti-haze is no different from climbing on foot.
Therefore, with the development of science and technology, the continuous automatic monitoring system of air quality, the online automatic monitoring system of flue gas, and the digital emergency monitoring vehicle and other instrument products comprehensively analyze the formation mechanism and diffusion law of secondary fine particles in haze, which affect haze and photochemistry.
Smog formation factors, pollution source analysis methods, etc.
, provide scientific basis for air pollution control, and extract scientific solutions from them.

In addition, in addition to the above-mentioned air quality monitoring system, Chinese scientists have developed a radar for detecting air pollution on the problem of "smog" monitoring.
Its shape is a laser beam that can detect the distance from the ground to the high altitude.
The distribution of smog in the middle and the analysis of the punishment of smog.
It can emit light beams at high altitude from any direction on the earth's surface, and can even move on the surface; the light beams will form a three-dimensional network.
This research and development is different from the previous air quality detection instruments, and successfully achieved no blind spots for air pollution phenomena such as smog.
The vertical three-dimensional detection also points out the direction for the treatment of air pollution.
