硫自养反硝化技术在污水深度处理中的研究和应用

Research and Application of Sulfur Autotrophic Denitrification Technology in Advanced Wastewater Treatment

硫自养反硝化技术因其污泥产量低、效率高、无需额外投加碳源等优点而受到广泛关注。其中以铁硫化物作为电子供体的硫自养反硝化技术还能达到同步脱氮除磷的目的,进一步降低了出水氮、磷浓度,对于水体富营养化问题的解决有很大意义。介绍了硫自养反硝化技术的生化原理,主要的电子供体,叙述了近些年应用于污水处理领域的技术和工艺,讨论今后的发展动态,旨在为未来硫自养反硝化工艺发展提供参考。

Sulfur autotrophic denitrification technology has received widespread attention due to its advantages such as low sludge yield,high efficiency,and no need for additional carbon sources.Among them,the sulfur autotrophic denitrification technology with iron sulfide as the electronic donor can also achieve the goal of simultaneous nitrogen and phosphorus removal,further reducing the nitrogen and phosphorus concentration in the effluent,which is of great significance for solving the problem of Eutrophication of water bodies.The biochemical principles and main electronic donors of sulfur autotrophic denitrification technology were introduced,the technologies and processes applied in the field of sewage treatment in recent years were described,future development trends were discussed,aiming to provide reference for the development of sulfur autotrophic denitrification technology in the future.
