新型复合填料强化两级曝气生物滤池脱氮效能研究

Research on Nitrogen Removal Efficiency of Anaerobic-aerobic Biological Filter Enhanced by New Composite Filter

针对传统BAF对TN去除率低,及运行过程中易堵塞的问题,采用环保海绵、陶粒和沸石组成的复合填料,开发了新型BAF技术。通过技术改进及参数优化,反应器对TN的去除率提高了27.6%,对COD的去除率提高了约10%。

Aiming at the problem of low removal rate of TN and blocking phenomenon in the traditional process of BAF,a new BAF technology was developed,which was composed by environmental sponge,ceramsite and zeolite filter. Through the technical improvement and optimization of parameters of the reactor,the removal rate of TN increased 27. 6%,the removal rate of COD increased about 10%.
