摘　　要：通过强化富集培养出高硝化细菌数量的硝化污泥,并以此选择性投加,进行因进水波动而导致出水氨氮异常增高生化系统的削峰试验。结果表明,在进水氨氮质量浓度为40 mg/L左右时,培养出的富集硝化污泥性能最好。当由于进水氨氮质量浓度变化而造成硝化系统稳定性受到冲击时,在保持适当碱度的条件下,投加质量分数0.5%和1.0%的富集硝化污泥,即可具有显著的出水氨氮削峰效果,对硝化系统性能的恢复和提升产生积极的影响。The nitrifying sludge with a large number of nitrifying bacteria is obtained by strengthening enrichment culture. The experiment of ＂cut peak ＂ of biochemical system is carried out by adding nitrifying sludge. The best performance of enriched nitrifying sludge can be achieved when the concentration of ammonia concentration in the influent water is 40 mg / L. If the nitrification system is affected by the fluctuations of ammonia-nitrogen in the influent water,the addition of 0. 5% or 1% of nitrifying sludge under adequate alkaline condition is useful to cut＂peak of ammonia-nitrogen＂. In addition,it also has a significant effect on the recovery and improvement of the nitrification system.
