Embodiment 1

[0021] Reference figure 1 , A method for the treatment of PM2.5 in the suburbs of Beijing. The method is to spray a solution containing haze agent and ozone at a height of 2000m in the suburbs of Beijing. The content of haze agent and ozone is 0.5kg / L and the content of ozone is 0.05g / L; Set up a moat around Beijing on the outskirts of Beijing, with a width of 5-6m. Use airplane to spray solution containing haze agent and ozone;

[0022] When the PM2.5 value is 150-250μg / m³, the dosage of the haze agent is 3.5-5kg / L, when the PM2.5 value is 75-150μg / m³, the dosage of the haze agent is 1-3.49kg / L , When the PM2.5 value is 35-75μg / m³, the dosage of haze agent is 0.5-1kg / L. The haze agent is prepared by the following method: 45 parts by weight of vegetable residue or peel, 8 parts by weight of tea, 5 parts by weight of mushrooms, 5 parts by weight of starter and 75 parts of clean water are fermented for 4 months and filtered get.

Embodiment 2

[0024] Reference figure 1 , A method for controlling PM2.5 in the suburbs of Beijing. The method is to spray a solution containing haze agent and ozone at a height of 200m in the suburbs of Beijing. The content of haze agent and ozone is 3kg / L and the content of ozone is 0.08g / L Establish a moat around Beijing on the outskirts of Beijing, with a width of 5-6m; use an ultra-high fog spray system to spray solutions containing haze and ozone; the ultra-high fog spray system includes a foundation base 1, high-pressure liquid pump 2 set on the ground , The electronic control device 3 connected to the high-pressure liquid pump 2, the PM2.5 monitoring device 4 connected to the electronic control device 3, the nozzle 5 and the horizontally rotatable nozzle 6, the height of the nozzle 5 is 200m; in Beijing A super-high fog spray system is installed every 150 kilometers in the suburbs; when the PM2.5 value is 150-250μg / m³, the amount of haze agent is 3.5-5kg / L, when the PM2.5 value is 75...

Embodiment 3

[0026] Reference figure 1 , A method for the treatment of PM2.5 in the suburbs of Beijing. The method is to spray a solution containing haze agent and ozone at a height of 500m in the suburbs of Beijing. The content of haze agent and ozone is 5kg / L and the content of ozone is 0.1g / L Establish a moat surrounding Beijing in the outskirts of Beijing, with a width of 5-6m; use an ultra-high fog spray system to spray solutions containing haze and ozone; an ultra-high fog spray system, including a foundation base set on the ground 1. High-pressure liquid pump 2. The electronic control device 3 connected to the high-pressure liquid pump 2, the PM2.5 monitoring device 4 connected to the electronic control device 3, the nozzle 5 and the horizontally rotatable nozzle 6, the height of the nozzle 5 is 500m; An ultra-high fog spray system is installed every 200 kilometers in the suburbs of Beijing; when the PM2.5 value is 150-250μg / m³, the amount of haze agent is 3.5-5kg / L, when the PM2.5 v...

Abstract

The invention relates to a treatment method of PM2.5 in suburban areas of Beijing. According to the method, a solution containing a haze covering agent and ozone is sprayed on the height position of 200-500 mm in the suburban areas of Beijing, the content of the haze covering agent is 0.5-5 kg / L, and the content of the ozone is 0.05-0.1 g / L. According to the treatment method, fresh natural air can be brought to Beijing, people can live in a fresh and clean living environment, and the groupment public health event caused by standard exceeding of bacteria and microorganisms in air can be reduced; hazardous substances can be decomposed in time, fresh air is conveyed, secondary harm to people from haze is reduced, and a forceful guarantee is provided for safety of public places; very important significance and high value are achieved for building a civilization and harmony society; and the happiness index of the city resident is increased, more residents can participate in outdoor sports, the fitness of the bodies of the residents is facilitated, and the morbidity is reduced.

Description

Technical field [0001] The invention relates to the field of air purification, in particular to a method for treating PM2.5 in the suburbs of Beijing. Background technique [0002] PM2.5 is a kind of fine particles, also known as fine particles or fine particles, which refers to those particles in the atmosphere with a particle size less than 2.5 microns. This kind of fine particulate matter accounts for a small proportion of the atmospheric composition, can stay in the atmosphere for a long time, can spread to far places, and seriously affect the visibility and quality of the atmosphere. In the newly revised "Ambient Air Quality Standards" issued 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 urban PM2.5. Taking Beijing as an example: 1. The introduction of external pollution; Inner Mongolia and Beijing are close to each other and located in the upper a...
