The advantages that efficient, but there is also take up a large area, operating cost is high, waste water and by-product gypsum secondary pollution problems；
Denitration then mainly use selective catalytic reduction (SCR) technology, reducing agent under the effect of the catalyst, by NOXIt is reduced to nitrogen
And water, catalyst are the core of SCR technology, V2O5/TiO2And its modified catalyst has obtained industrial applications.However desulfurization
Denitrification integral technology is not only without the problems of the independent desulfurization of solution, but also domestic SCR technology and used catalyst are almost
All quoted from foreign countries or by import, investment and operating cost are very high.Simultaneous SO_2 and NO removal technology can be in a process by cigarette
SO in gas2And NOXThe technology of removing simultaneously, not only saving space makes device resource effectively be configured, it is often more important that work
Skill is simple, reduces capital construction and operating cost.So exploitation simultaneous SO_2 and NO removal technique will be smoke gas treatment technology development from now on
Main trend, and associated catalysts and preparation method then be develop this technique the focus of work.
