【摘要】 综述了含氨废水处理的传统硝化/反硝化途径的新发展,并对短程硝化/反硝化、厌氧氨氧化、好氧反硝化、人工湿地等新途径的研究进展进行了分析。指出传统途径的研究方向是剩余污泥的处理和提高菌体的代谢强度;建议重视对短程硝化的溶氧等问题的研究,开发出更加高效、普适性更强的短程硝化工艺;深入研究厌氧氨氧化途径的机理,利用生物工程技术培育高生长速率的菌株;对于好氧反硝化途径,研究如何控制外界条件以利于好氧反硝化菌的累积;在人工湿地方面,加强对耐高盐碱环境植物的研究并用生物修复技术对其进行改良,以开发盐碱地、滩涂等生产力较低下的土地资源。更多还原

【Abstract】 Development of nitrogen wastewater treatment is reviewed. The process of traditional nitrification and denitrifica-tion pathway, technologies involved in novel pathways such as shortcut nitrification-denitrification, anammox, aerobic denitrifica-tion, constructed wetlands, etc. , are summarized. It is pointed out that working on avoiding residual sludge and enhancing metab-olizability of microorganism will improve traditional methods. Study on factors like dissolved oxygen is recommended in shortcut nitrification-denitrification. And mechanism of anammox needs to be studied to improve conversion ability of "aerobic" ammonium oxidizers. It is also valuable to seek out methods of accumulation of aerobic denitrifier by controlling environmental conditions . Strengthening the research of plants can endure high salinity and alkalinity and meliorating these plants by using biological technologies will make it easier to develop land resource which has poor fertility,such as salina and swamp.更多还原
