Description
Technical field
The present invention relates to field hazes to administer field, and in particular to photocatalysis eliminates the auxiliary agent of haze, more particularly to one
The quick elimination haze of kind low cost removes haze auxiliary agent and preparation method.
Background technology
Haze is the particles such as the PM2 .5 equidimensions particle, dust, aerosol floated in air, in certain humidity, temperature
The weather phenomenon generated under the weather conditions metastable states such as degree is specific weather condition and the knot of mankind's activity interaction
Fruit.Haze main constituents are sulfur dioxide, nitrogen oxides and pellet.The main reason for forming haze is
Industrial production discharge, vehicle exhaust, coal combustion exhaust, construction site and road traffic airborne dust etc..China's haze pollution has been in more next
Stronger trend, haze can generate serious adverse effect to health, the ecosystem and traffic safety caused seriously to endanger
Evil, has made hot issue in recent years.
At present, the main method for administering haze is to reduce pollutant emission, afforestation and water spray except haze.It sprays water except haze is
Currently used technological means, but can only be effective to the inorganic solid particles in haze, and then cannot root to organic aerosol
This removal.In practice, elimination haze that can only be of short duration frequently with the water spray of flood tide, not only water consumption is big, and needs to continue
Water spray could inhibit haze.In recent years, become a kind of emerging and efficient technology using photocatalysis technology degradation haze, be subject to
The common concern of people.At present, except haze effect is good, efficient, quick, harmless to human body and Environmental security, spy easy to use
The drop haze auxiliary agent of point becomes the Main Topics that haze is administered.
