Embodiment 1

[0021] refer to figure 1 , a control method of PM2.5 in the suburbs of Beijing. The method is to spray a solution containing haze-retaining agent and ozone at a height of 2000m in the suburbs of Beijing. The content of haze-retaining agent is 0.5kg / L, and the content of ozone is 0.05g / L; Set up a moat around Beijing in the suburbs of Beijing, with a width of 5-6m. Use airplanes to spray solutions containing haze agents 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 the haze agent is 0.5-1kg / L. The haze-reducing agent is prepared by the following method: 45 parts by weight of vegetable dregs or peels, 8 parts by weight of tea leaves, 5 parts by weight of mushrooms, 5 parts by weight of starter and 75 parts of clear water are fermented for 4 months and then filtered get.

Embodiment 2

[0024] refer to figure 1 , a method for controlling PM2.5 in the suburbs of Beijing. The method is to spray a solution containing haze-retaining agent and ozone at a height of 200m in the suburbs of Beijing. The content of the haze-retaining agent is 3kg / L, and the content of ozone is 0.08g / L ; Set up a moat around Beijing in the suburbs of Beijing, with a river width of 5-6m; use a super-high fog spray system to spray solutions containing haze agents and ozone; , an electric control device 3 connected to the high-pressure liquid pump 2, a PM2.5 monitoring device 4 connected to the electric control device 3, a nozzle 5 and a horizontally rotatable nozzle 6, and the height of the nozzle 5 is 200m; in Beijing Set up an ultra-high fog spray system every 150 kilometers in the suburbs; when the PM2.5 value is 150-250μg / m3, the amount of haze agent used is 3.5-5kg / L, and when the PM2.5 value is 75-150μg / m3 , the consumption of the haze suppressing agent is 1-3.49kg / L, when the PM2....

Embodiment 3

[0026] refer to figure 1 , a method for controlling PM2.5 in the suburbs of Beijing. The method is to spray a solution containing a haze agent and ozone at a height of 500m in the suburbs of Beijing. The content of the haze agent is 5kg / L, and the content of ozone is 0.1g / L ; Set up a moat around Beijing in the suburbs of Beijing, with a river width of 5-6m; use an ultra-high fog spray system to spray solutions containing haze agents and ozone; the ultra-high fog spray system includes a foundation base set on the ground 1, a high-pressure liquid pump 2. The electric control device 3 connected to the high-pressure liquid pump 2, the PM2.5 monitoring device 4 connected to the electric control device 3, the nozzle 5 and the horizontally rotatable nozzle 6, and the height of the nozzle 5 is 500m; Set up an ultra-high fog spray system every 200 kilometers in the suburbs of Beijing; when the PM2.5 value is 150-250μg / m3, the dosage of the haze agent is 3.5-5kg / L, and 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 treatment method for PM2.5 in the suburbs of 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 ...
