Description
Technical field
The fast purification agent the present invention relates to a kind of water base haze (fine particle) is met an urgent need.More specifically to a kind of water base
Haze (pm2.5) is met an urgent need fast purification agent, belongs to public health and security fields.
Background technology
Haze is also called fine particle, pm2.5.Fine particle finger ring border in the air equivalent aerodynamic diameter be less than etc.
In 2.5 microns of particulate matter.It can be suspended in the air long period, its in atmosphere content concn higher, just represent sky
Gas pollution is more serious.Although pm2.5 is the little component of content in earth atmosphere composition, it is to air quality and visibility
Etc. there being important impact.Compared with thicker Atmospheric particulates, pm2.5 particle diameter is little, and area is big, and activity is strong, easily subsidiary poisonous, have
Evil material (for example, heavy metal, microorganism etc.), and time of staying length in an atmosphere, fed distance are remote, thus to health
Bigger with the impact of atmosphere quality.
The chemical composition of pm2.5 includes inorganic constituentss, organic principle, minor metallic element, elemental carbon, biological substance (carefully
Bacterium, pathogenic bacteria, mycete etc.) etc..Carbon contg particle in air is made up of the elemental carbon (ec) of organic carbon (oc) and extinction, element
Similar to impure graphite, organic carbon is content highest component in pm2.5 to the chemical constitution of carbon.
In air, fine particle mainly has Water-soluble inorganic ions, carbonaceous material and insoluble mineral to constitute, wherein water-soluble
Property inorganic ionss and carbonaceous material are mainly derived from the combustion process of all kinds of Fossil fuels and biomass, and gaseous contaminant
Conversion.Pm2.5 is by being directly discharged into the primary particle of in the air and the gaseous contaminant of in the air is generated by chemical conversion two
Secondary particle composition.The primary particle mainly carbon black (organic carbon) producing that burns by dust particle and by plant and fossil fuel
Particle two big class forms.Offspring is mainly by ammonium sulfate and ammonium nitrate (reacting generation by so2 and nox in air and nh3)
Composition, the main process that it forms is gaseous contaminant so2 and nox in air by homogeneous or heterogeneous oxidation shape
Become acid aerosol, then generate ammonium sulfate (ammonium sulfite) and ammonium nitrate gas with the gas nh3 reaction of meta-alkalescence unique in air
Sol particles.Water droplet in air is that these chemical conversion process provide important precondition.So, the water droplet in air
Just easily become the secondary pollution important medium that low latitude constantly accumulates below 1000 meters.
Organic substance is the important chemical species in Chinese pm2.5；so4 2-, so3 2-, no3 -, nh4 +, cl-It is East China
Topmost chemical species in pm2.5；The high-load of soil dirt is a feature of Chinese pm2.5, on the ground being affected by sand and dust
Area and season are more so.
Polycyclic aromatic hydrocarbon (polycyclic aromatic hydrocarbons, abbreviation pahs) is the weight of Atmospheric particulates
Want ingredient, be a kind of carcinogenic, teratogenesis, mutagenic material, participate in biological and human body metabolism, have very strong
Toxicity.
The composition of haze particulate matter is very complicated, depends primarily on its source.Mainly there are natural source and two kinds of artificial source, but danger
That evil is larger is the latter.
Natural source include soil airborne dust (containing oxide mineral and other compositions) sea salt (the second largest source of particulate matter,
Its composition is similar with the composition of sea water), plant pollen, spore, antibacterial etc..
Artificial source includes stationary source and mobile source.Stationary source includes various fuel combustion sources, such as generating, metallurgy, oil, change
The various industrial process such as, textile printing and dyeing, heat supply, the coal-fired flue dust with combustion gas or fuel emission in gastronomical process.Mobile source master
If all kinds of vehicles when in running using fuel to air in discharge tail gas.Between past 50 years, due to
Gradually made no public appearances using coal in the family in London and industry, traffic emission becomes the source of the maximum of air pollution.
The nitrogen oxides of London in the air 58%, and 68% pm10 contaminant particle both is from motor vehicle exhaust emission.Indoors, two
Handss cigarette is the topmost source of particulate matter.
Although fine particle is the little component of content in earth atmosphere composition, research shows, fine particle is to human body
The harm of health is bigger, because diameter is less, the position entering respiratory tract is deeper.The particulate matter of 10 μ m diameter is usually deposited at
Upper respiratory tract, less than 2 μm of be deep into bronchioless and alveolar.Fine particle enters human body to after alveolar, directly affects lung
Ventilatory function, make body easily be in anaerobic condition.

On October 17th, 2013, international cancer research institution of World Health Organization (WHO) issued report, pointed out atmospheric pollution pair first
The mankind are carcinogenic, and regard it as universal and main environmental carcinogen.When the concentration of in the air pm2.5 is higher than 10 μ g/m for a long time, just
The rising of mortality risk can be brought.Concentration often increases by 10 μ g/m, and total mortality risk rises 4%, the dead wind that heart and lung diseases bring
Danger rises 6%, and the mortality risk that pulmonary carcinoma is brought rises 8%.Additionally, the organic pollution such as pm2.5 easily absorbing multiring aromatic hydrocarbon and weight
Metal, makes carcinogenic, teratogenesis, mutagenic probability significantly raised.
In addition, pm2.5 can affect into cloud and rainfall, remote-effects climate change.Under the conditions of some, pm2.5 meeting
Increase the quantity of the nuclei of condensation, the raindrop making sky aerial increase, it may happen that heavy rain when extreme.
Therefore, concern fine particle present situation and development trend, inquires into and how to pay attention to and take precautions against pm2.5, concerning human health,
The important topic of safety and economy coordinated development.
