包埋硝化菌流化床处理温瑞塘河河水的中试研究

以快速去除温瑞塘河河水中的氨氮为目的，研究了包埋硝化菌流化床中试装置处理河水的特性.研究结果表明，在实验条件下，当进水氨氮平均值为6.15 mg/L时，氨氮平均去除率可达到45.50%，且转化产物基本上以硝酸盐氮为主.此外，中试装置对河水中的COD_Mn也具有一定的去除效果.包埋硝化菌流化床可以对河水中毒害性较大的氨氮进行快速转化，在城市河道的治理方面具有一定的应用前景.

Pilot scale study on the treatment of water in Wenruitang River by fluidized bed reactor with embedded nitrobacteria

The treatment characteristics of a pilot scale fluidized bed reactor with embedded nitrobacteria was investigated to rapidly remove ammonia from Wenruitang River. Results showed that 45.50% of the ammonia nitrogen in the Wenruitang River was removed by the fluidized bed reactor with the average influent ammonia nitrogen concentration of 6.15 mg/L. The main product of the nitrification process was nitrate nitrogen. COD_Mn could also be removed during the treatment process. Harmful ammonia nitrogen in urban rivers could be rapidly be removed by the fluidized bed reactor with embedded nitrobacteria. This could be applied in the treatment of urban river water.
