焦化废水生物脱氮工艺的探讨

焦化废水是一种氨氮和有机物浓度较高的难生化降解有机废水。随着排放指标的日益严格，出现了很多焦化废水的处理新技术，而焦化废水的生物脱氮技术的发展是其中非常重要的一个方面。本文以生物脱氮硝化／反硝化反应的反应途径为线索，系统分析了国内外近年来在焦化废水生物脱氮方面的研究进展，并简要介绍了国外一些生物脱氮的新技术，包括SHARON工艺、OLAND工艺和ANAMMOX工艺。

Advance in the Research of Biological Nitrogen Removal from Coke Plant Wastewater

Coke plant wastewater is a kind of refractory organic one which has high concentration of ammonia and organisms. As the discharge standard becoming more and more strict, some new technologies for the wastewater treatment turn up. Biological nitrogen removal is one important aspect in this field, which is discussed according to the nitrification and denitrification process. This paper also introduces some potential new methods and their advantages and disadvantages.
