介绍一种新型沸石填料 ,用于提高生物脱氮系统中硝化反应器的硝化性能。试验结果表明 ,应用了沸石填料的硝化反应器的硝化性能得到了显著提高 ,在脱氮效率和速率上 ,与普通生物载体硝化反应器相比具有明显的优势。硝化反应器连续运行 17d ,出水氨氮基本在 1mg/L以下 ,氨氮去除率在 97%以上。该系统停止运行 5 0d后再次启动 。

A novel permutit filling for further improving the nitrification performance of the nitrification reactor in biological nitrogen removal system is presented in this paper. The experimental results indicated that the nitrification reactor using permutit filling could improve nitrification performance and had evident advantages over those using normal biocarriers in efficiency. During the continuous running for 17 d, NH-3-N in the effluent had basically been lower than 1 mg/L and the removal ratio of NH-3-N had always been at a level higher than 97%. The nitrification performance of the reactor was recovered in a week after it had been stopped for 50 days.
