摘　　要：为实现短程硝化的快速启动,采用序批式反应器(SBR),在实时控制条件下,探究短程硝化的启动策略,考察短程硝化的启动过程,并分析稳定短程硝化条件下典型周期内氮素及有机物的转化情况。研究结果表明,在进水COD/ρ(TN)为1,温度为30~35℃,pH为7.5~8.1,DO的质量浓度为0.3~0.5 mg/L的条件下,使反应剩余FA的质量浓度为0.13~0.39 mg/L,可在第8天(16个周期)启动短程硝化(连续7个周期维持85%以上的NAR视为启动成功),并稳定32 d,亚硝积累率(NAR)达90%以上。稳定阶段时,氮素及有机物的去除转化符合线性变化规律,平均比氨氧化速率(SAOR)为10.98 mg/(mg·h),是启动阶段的2倍。In order to achieve quick start-up of partial nitrification, sequential batch reactor (SBR) was used to investigate the start-up strategy and process of partial nitrification under conditions of real-time control, and analyze the typical period of nitrogen under stable partial nitrification conditions as well as the conversion of organic matter. The results showed that the residual mass concentration of F A of the reaction was 0.13-0.39 mg/L under the condition of influent COD/ρ(TN) of 1, temperature of 30-35℃, pH of 7.5-8.1 and mass concentration of DO of 0.3-0.5 mg/L. Partial nitrification could be started on the 8th day (the 16th cycle)(the N A R was maintained at 85 % or more for 7 consecutive cycles) and stabilized for 32 d, and the nitrite accumulation rate (NAR) was over 90%.During the stabilization phase, the removal and conversion of nitrogen and organic matter conformed to linear variation, and the average specific ammonia oxidation rate (SAOR) was 10.98 mg/(mg·h), which was twice that of the start-up phase.
