湿法络合脱硝及其再生技术的研究进展

Researches in wet complexation denitrification and regeneration technologies

湿法脱硝具有同时脱硫脱硝的特点,在氮氧化物排放控制中显现出明显的优势。湿法脱硝技术包括直接吸收法、氧化吸收法、还原吸收法和络合吸收法等。对比了各种技术特点,总结了生物法、还原法和电解法再生吸收液的方法,以及辅助抗氧化剂的种类。

Wet denitrification method,being able to desulfurizing and denitrifying simultaneously,has obvious advantages in NOx emission control.Wet denitrification technologies include direct absorption,oxidation absorption,reduction absorption and complexation absorption.This article compares various wet denitrification technologies and outlines biological method,reduction method,electrolytic regeneration absorption solution method,and the types of supplementary antioxidants.
