摘　　要：含氨废水的短程硝化能够实现节能降耗,是目前废水生物脱氮领域的研究热点.本文分析了短程硝化的原理及基于短程硝化的新型生物脱氮工艺的优势,探讨了温度、pH、溶解氧、游离氨、污泥龄等控制条件对实现短程硝化的影响以及适宜的参数范围,并介绍了短程硝化的工艺途径.Partial nitrification of ammonia-containing wastewater can save energy and reduce cost, and has become one of the hotspots in the research of biological nitrogen removal from wastewater. The principle of partial nitrification and the merits of a new process based on that principle were analyzed, effects of the controlling conditions such as temperature, pH, dissolved oxygen, free ammonia and sludge age were discussed, and some new processes for partial nitrification were presented.
