Embodiment 1

[0025] In Beijing, for example:

[0026] refer to figure 1 , a treatment method for reducing PM2.5 in Beijing. This method is divided into three layers of treatment. The first layer is ground greening, the second layer is vertical greening and wall greening that are symbiotic with middle and high-rise buildings or elevated roads, and the third layer is The ultra-high fog spray system and greening on the top of high-rise buildings. The super-high fog spray system is installed on the top of high-rise buildings. The distance from the nozzle to the top of the building is 150m. The tap water containing the haze suppressing agent is 0.5-5kg / L, and the tap water containing the haze suppressing agent is sprayed at road intersections in Beijing at the same time. The ultra-high fog spray system includes a foundation base 1 arranged on the top of a high-rise building, a high-pressure liquid pump 2, an electronic control device 3 linked with the high-pressure liquid pump 2, a PM2.5 monit...

Embodiment 2

[0030] refer to figure 1, a treatment method for reducing PM2.5 in Beijing. This method is divided into three layers of treatment. The first layer is ground greening, the second layer is vertical greening and wall greening that are symbiotic with middle and high-rise buildings or elevated roads, and the third layer is The super-high fog spray system and greening on the top of high-rise buildings. The super-high fog spray system is installed on the top of high-rise buildings. The distance from the nozzle to the top of the building is 200m. The tap water containing the haze suppressing agent is 0.5-5kg / L, and the tap water containing the haze suppressing agent is sprayed at road intersections in Beijing at the same time. The ultra-high fog spray system includes a foundation base 1 arranged on the top of a high-rise building, a high-pressure liquid pump 2, an electronic control device 3 linked with the high-pressure liquid pump 2, a PM2.5 monitoring device 4 linked with the elect...

Embodiment 3

[0034] refer to figure 1 , a treatment method for reducing PM2.5 in Beijing. This method is divided into three layers of treatment. The first layer is ground greening, the second layer is vertical greening and wall greening that are symbiotic with middle and high-rise buildings or elevated roads, and the third layer is The super-high fog spray system and greening on the top of high-rise buildings. The super-high fog spray system is installed on the top of high-rise buildings. The distance from the nozzle to the top of the building is 220m. The tap water containing the haze suppressing agent is 0.5-5kg / L, and the tap water containing the haze suppressing agent is sprayed at road intersections in Beijing at the same time. The ultra-high fog spray system includes a foundation base 1 arranged on the top of a high-rise building, a high-pressure liquid pump 2, an electronic control device 3 linked with the high-pressure liquid pump 2, a PM2.5 monitoring device 4 linked with the elec...

Abstract

The present invention relates to a governance method for reducing PM2.5 in Beijing. The method comprises three levels of governance. The first level of governance is ground greening, the second level of governance is symbiotic vertical greening for high-rise buildings or elevated road and wall greening, and the third level of governance is an ultra-high mist spray system and greening at the tops of high-rise buildings. The ultra-high mist spray system is installed on the tops of high-rise buildings, and the distance from the vents to the top of the building is 150-220m; and the ultra-high mist spray system uses tap water containing a haze management agent in the content of 0.5-5 kg/L. Planting of suitable tree species can beautify the urban landscape, purify the air of the city, cover middle and high level roofs and high level wall with green plants, ease the urban heat island effect, expand the living space of modern urban citizens and improve the happiness index in the city. The method can allow more residents to participate in outdoor sports, and reduce incidence of disease.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a treatment method for reducing PM2.5 in Beijing. Background technique [0002] PM2.5 is a kind of fine particulate matter, also known as fine particles or fine particles, which refers to those particles in the atmosphere whose particle size is less than 2.5 microns. This kind of fine particles accounts for a small proportion of atmospheric components, can stay in the atmosphere for a long time, and can spread to far away places, seriously affecting the visibility and quality of the atmosphere. In the newly revised "Ambient Air Quality Standards" released by the State Council in February 2012, "fine particulate matter" in the air has become a new monitoring indicator. [0003] Generally speaking, there are three main sources of PM2.5 in cities. Take Beijing as an example: 1. The introduction of external pollution; Neighboring Shanxi is also a very important energy base in China,...
