摘要
介绍了反硝化生物滤池(DNBF)的工作原理及类型,阐述了DNBF对氨氮、总氮、有机物及悬浮物等污染物的去除效果。探讨了碳源、p H、温度、溶解氧、回流比、水力负荷、反冲洗、挂膜等因素对DNBF处理效果的影响。指出了DNBF目前存在的问题,展望了DNBF未来的发展方向,为相关理论研究以及实际工程应用提供参考依据。
Introducing the working principle and the type of denitrifying biological filter(DNBF)and expatiates the treatment effect of DNBF on ammonia nitrogen,total nitrogen,organics and suspended matter.In addition,the effects of carbon source,pH,temperature,dissolved oxygen,reflux ratio,hydraulic load,backwashing and the biofilm way were discussed.The existing problems and the future development trend of DNBF were pointed out in order to provide reference for theoretical research and practical engineering application.
