氨氮废水生物处理技术研究进展

摘要

氨氮废水是造成河流及湖泊富营养化的主要因素，因此广泛开展研究了高效的处理氨氮废水，以降低河流及湖泊中的氨氮物质的技术。本文综述了氨氮废水主要生物处理新工艺，其中包括同步硝化反硝化、短程硝化反硝化、厌氧氨氧化、短程硝化-厌氧氨氧化联合工艺，简单概括了各方法的物理化学处理技术及其工艺，以及比较它们在工业中的应用和特点，并探讨了氨氮废水降解机制，综述了目前国内外研究进展状况。%The ammonia-nitrogen wastewater is the main factor of rich nourishment in the polluted rivers and lakes. Thus, highly efficient process to deal with amnonia-nitrogen from wastewater in order to decrease amnonia-nitrogen content of rivers and lakes is widely applied. Some new biological processes to remove ammonia-nitrogen in wastewater were discussed, including SHARON, SND, ANAMMOX and SHARON-ANAMMOX. The physical and chemical treatment technology and characteristics of these biotechnology processes were mainly introduced. Different methods were compared in industry apply and their advantages and disadvantages were found. Besides, the degradation mechanism of ammonia nitrogen from wastewater was discussed, the development trend of biotechnology process for removing ammonia-nitrogen for wastewater was predicted.
