摘要

Abstract

During wet complexation denitrification of flue gas

EDTA regeneration

also known as reducing Fe

III

EDTA and Fe

EDTA-nitric oxide (NO) to Fe

EDTA

is crucial. In this paper

ultraviolet (UV) light was used for the first time to reduce Fe

EDTA-NO. The experimental result demonstrated that Fe

EDTA-NO reduction rate increased with UV power increasing

elevated temperature

and initial Fe

EDTA-NO concentration decreasing. Fe

EDTA-NO reduction rate increased first and then decreased as pH value increased (2.0-10.0). Fe

EDTA-NO reduction with UV irradiation presented a first order reaction with respect to Fe

EDTA-NO. Compared with other Fe

EDTA regeneration methods

EDTA regeneration with UV show more superiority through comprehensive consideration of regeneration rate and procedure. Subsequently

NO absorption experiment by Fe

EDTA solution with UV irradiation confirmed that UV can significantly promote the NO removal performance of Fe

EDTA. Appropriate oxygen concentration (3% (vol)) and acidic environment (pH = 4) was favorable for NO removal. With UV power increasing as well as temperature decreasing

NO removal efficiency rose. In addition

the mechanism research indicates that NO from flue gas is mostly converted to NO

and N

O with Fe

EDTA absorption liquid with UV irradiation. UV strengthens NO removal in Fe

EDTA absorption liquid by forming a synergistic effect of oxidation-reduction-complexation. Finally

compared with NO removal methods with Fe

EDTA

EDTA combined UV system shows prominent technology advantage in terms of economy and secondary pollution.
