基于硫循环的污水处理工艺--SANI工艺研究进展

摘要

The sulfate reduction,autotrophic denitrification and nitrification integrated(SANI)process is a new wastewater treatment process based on sulfur cycle and low sludge production. This technology not only can successfully meet the requirements,such as removing organic matter,nitrogen and disinfection,etc.,but also solve the problems of producing a large amount of sludge from the sources during wastewater treatment process. The origin, form,principle,development process and current research situation of SANI process and its modification process are summarized in detail,and problems existing in its technology analyzed. At the end,future research directions of SANI process are predicted,so as to provide new ideas for the development of wastewater treatment fields.%硫酸盐还原、自养反硝化和硝化集成工艺（ sulfate reduction，autotrophic denitrification and nitrification integrated，SANI）是一种基于硫循环、低污泥产出的污水处理新工艺。该工艺不仅可实现去除有机物、脱氮、消毒等水处理要求，还从源头上解决了污水处理产生大量污泥的问题。对SANI工艺及其改型工艺的起源、形式、原理、研究现状进行了详细综述，对该工艺存在的问题进行了分析，并对未来研究方向进行了展望，以期为污水处理行业的发展提供新思路。
