摘要
传统生物脱氮除硫过程中存在着许多问题。近年来,通过对脱氮微生物的深入研究,生物脱氮技术取得了突破性进展,而在生物同步脱氮除硫方面发展相对缓慢。总结了包括反硝化除硫、硫酸盐还原—自养反硝化—硝化、反硝化氨氧化以及硫酸盐型厌氧氨氧化等生物同步脱氮除硫工艺的特点,分析了各自的工艺原理及面临的挑战,并提出了今后的研究方向。
There are some problems in conventional biological nitrogen removal and sulfur-removal processes. With the recently intensive study of nitrogen removal microorganisms, significant progresses have been made in bio logical nitrogen removal technologies. Comparatively speaking, the development of biological processes for simultane-ous removal of nitrogen and sulfur is relatively slow. This review summarizes the features of the processes for simul- taneous removal of nitrogen and sulfur, including denitrifying sulfide removal, sulfate reduction-autotrophic denitrifi cation-nitrification integrated process, denitrifying ammonium oxidation, sulfate dependent ANAMMOX, it also ana lyses their principles and challenges. Then a prospect concerned for future research is also put forward.
