Among them, the contribution rate of industrial sources to PM2.5 in Wuhan ranks first.
A preliminary study on the causes of smog in Wuhan shows that external pollution accounts for about 20-30% in Wuhan.
Endogenous pollutants are the main reasons, and the three main sources are industrial emissions, automobile exhaust emissions and urban dust pollution.
Among them, the contribution rate of industrial sources to PM2.5 in Wuhan ranks first, accounting for about 40%, the contribution rate of dust is about 25%, the exhaust emission of motor vehicles is about 20%, and the others are domestic sources and rural non-point sources.
The Urban Ambient Air Quality Standard Planning and Wuhan Air Quality Improvement Action Plan compiled by Wuhan Municipality have clearly defined the phased goals and tasks of improving air quality.
The overall goal is: after five years of hard work, the city's air quality has generally improved and the heavily polluted weather has been greatly reduced; Strive to use another five years, basically eliminate the heavily polluted weather, and obviously improve the urban air quality.
Specific indicators: By 20 17, the average annual concentration of inhalable particulate matter (PM 10) in the air in this city will be 20% lower than that in 20 12, and the average annual concentration of fine particulate matter (PM2.5) will be 20% lower than that in 20 13, and the number of days with good air quality will generally increase year by year.
Focusing on the "smog control plan", Wuhan will focus on the following three tasks: First, accelerate the adjustment of energy structure; Second, speed up the adjustment of industrial structure and layout; Third, vigorously reduce the emission of air pollutants, control industrial pollution, control motor vehicle pollution, reduce dust pollution, and reduce the pollution emissions of cooking fume and garbage incineration.
