摘　　要：为了提高废水生物处理过程的脱氮性能,设计了树脂-气升式环流生物反应器,通过实验考察了该反应器连续抗氨氮冲击的能力,并验证了反应器中吸附铵离子的强酸阳离子树脂生物再生的可行性,分析了生物再生机理。结果表明,原水中铵离子之外的阳离子的存在是实现树脂生物再生的关键。Resin containing airlift loop reactor was treatment process of wastewater. Ammonia loading shock designed to enhance the denitrification in the biological resistance of the reactor in continuous mode was investi- gated in the experiment. The biological regeneration of the strong acid cation resin in the reactor, which had ad- sorbed ammonium ion, was also proved and the riaechanism was explained. It was shown that the presence of non-ammonium cations in the raw water played an important role in the biological regeneration of the resin.
