催化加氢法脱除水中硝酸盐的研究进展

Advance of aqueovs nitrate removal by catalytic hydrogenization

近年来,地下水中硝酸盐污染日益严重。催化加氢还原硝酸盐生成氮气具有高效、无二次污染等特点,是一种应用前景良好的脱氮技术。本文结合国内外最新的研究进展,对硝酸盐和亚硝酸盐的催化加氢脱氮进行了综述,并对该领域的研究进行了展望。

Nitrate pollution became more serious in the groundwater. The catalytic hydrogenization process offers a practical approach to remove nitrate from water due to the high efficiency and the benefit free from secondary pollution. In this paper, the catalytic reduction of nitrate and nitrite were reviewed and the research progress was addressed. Finally,the future research in this field was recommended.
