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。

Abstract: Resin containing airlift loop reactor was designed to enhance the denitrification in the biological treatment process of wastewater. Ammonia loading shock resistance of the reactor in continuous mode was investigated in the experiment. The biological regeneration of the strong acid cation resin in the reactor, which had adsorbed ammonium ion, was also proved and the mechanism 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.-
