摘　　要：采用ABR工艺对肉类加工废水进行前期氨化处理,通过试验得到最佳水力停留时间为6～8h,氨氮递增率在90%～196%之间;同时发现了厌氧氨氧化这一新现象;最后对氮素、pH等水质指标在氨化反应过程中的的转化规律进行了分析,以期为肉类加工废水的生物脱氮处理工艺提供一定的理论指导。Meat processing wastewater was treawnent by ABR process. Through the test, the optimal hydraulic retention time （HRT） was found to be within 6h-8h, NH3-N increasing rate, within 90%-96%, and a new phenomenon of anaerobic ammoniation was found, Finally the conversion regulation of nitrogen, pH etc, water quality indexes in the course of ammoniation reaction was analysed to provide theoretical guiding for the biological denitrification of meat processing wastewater.
