摘　　要：分析了现有短程硝化反硝化工艺处理高浓度氨氮废水所存在的问题,试验利用序批式反应器(SBR)的内部水力特性对其进行改造,以畜禽养殖废水为研究对象,从宏观上创造同步硝化反硝化(SND)条件,并实现了同一反应器内短程硝化反硝化的同步进行,改造后系统pH值下降速度减缓,反硝化效率提高,最终出水的亚硝酸盐和硝酸盐浓度分别降低了39%和38%。Problems of short-cut nitrification and denitrification technique in the treatment of wastewater with ammonia nitrogen of high concentration were analyzed. The sequencing batch reactor （SBR） was modified based on its hydraulic characteristics. Taking piggery wastewater as a case, the simultaneous short-cut nitrification and denitrification （SND） condition was provided and the SND in the improved SBR was realized. Comparing with the usual SBR, the pH value of the new system dropped more slowly and the denitrification efficiency was improved. 39 % of the nitrite and 38 % of the nitrate were removed respectively.
