摘要
太湖蓝藻危机进一步促使国内重点流域提高了氨氮及总氮的最高允许排放标准,推动了含氮废水处理技术的创新开发和处理工艺的应用推广。目前应用的脱氮技术主要包括物化法和生化法两大类,其中生化法中的新型生化脱氮技术是近年的研究热点,包括同步硝化反硝化、短程硝化反硝化、厌氧氨氧化和全程自养脱氮等工艺。综述了物化、生化及物化-生化集成脱氮技术,分析了含氨氮、有机氮、硝态氮、垃圾渗滤液等含氮废水适宜的处理工艺,指出物化-生化集成工艺及新型生物技术是经济、高效、稳定脱氮技术的发展趋势。
The present paper is inclined to review the recent advances in treating nitrogen-containing pollutants for the aquatic environment by taking the blue algae bloom of Taihu Lake for example. As is known, industrial sewage, household sewage and fish farming sewage are the three major sources of nitrogen-containing sewage. In this paper, two kinds of treating technology, are mainly discussed, especially the new biological nitrogen removal technology, including simultaneous nitrification and denitrification, short-term nitrification-denitrification, anaerobic ammonium oxidation and deammonification. In addition, the physical-chemical process, the biological denitrification process and the integration process have been introduced with a brief mentioning of the treating processes of typical nitrogen-containing wastewater, such as ammonia nitrogen, organic nitrogen, nitrate wastewater and landfill leachate. Besides, a primary prospect for the development tendency of economic, efficient and steady techniques has also been made. Thus, it can be seen that the biological treatment technology will be made more popular in pollution control and reduction of the pollution coming from nitrogen-containing contaminants.
